Introduction
Indicates a hazardous situation which, if not avoided, will result in death or serious injury.
DANGER
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
WARNING
Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
CAUTION
Indicates practices not related to personal injury.
NOTICE
Ensure that all connections to the product are correct so as to avoid accidental risk of shock
DANGER and/or fire, for example such as can arise from high voltage connected to low voltage terminals.
Follow the requirements of this manual, including adequate wiring size and type, terminal torque settings, voltage,
current magnitudes applied, and adequate isolation/clearance in external wiring from high to low voltage circuits.
Use the device only for its intended purpose and application.
Ensure that all ground paths are uncompromised for safety purposes during device operation and service.
Ensure that the control power applied to the device, the AC current, and voltage input match the ratings specified on
the relay nameplate. Do not apply current or voltage in excess of the specified limits.
Only qualified personnel are to operate the device. Such personnel must be thoroughly familiar with all safety
cautions and warnings in this manual and with applicable country, regional, utility, and plant safety regulations.
1 Hazardous voltages can exist in the power supply and at the device connection to current transformers, voltage
transformers, control, and test circuit terminals. Make sure all sources of such voltages are isolated prior to
attempting work on the device.
Hazardous voltages can exist when opening the secondary circuits of live current transformers. Make sure that
current transformer secondary circuits are shorted out before making or removing any connection to the current
transformer (CT) input terminals of the device.
For tests with secondary test equipment, ensure that no other sources of voltages or currents are connected to such
equipment and that trip and close commands to the circuit breakers or other switching apparatus are isolated,
unless this is required by the test procedure and is specified by appropriate utility/plant procedure.
When the device is used to control primary equipment, such as circuit breakers, isolators, and other switching
apparatus, all control circuits from the device to the primary equipment must be isolated while personnel are
working on or around this primary equipment to prevent any inadvertent command from this device.
Use an external disconnect to isolate the mains voltage supply.
LED transmitters are classified as IEC 60825-1 Accessible Emission Limit (AEL) Class 1M. Class 1M
CAUTION devices are considered safe to the unaided eye. Do not view directly with optical instruments.
This product is rated to Class A emissions levels and is to be used in Utility, Substation Industrial
NOTICE environments. Not to be used near electronic devices rated for Class B levels.

2.2 Security
The following security features are available:
• Password security — Basic security present by default
• EnerVista security — Role-based access to various EnerVista software screens and configuration elements. The
feature is present by default in the EnerVista software.
• CyberSentry security — Advanced security available as a software option. When purchased, the options are
automatically enabled, and the default Password security and EnerVista security are disabled.
• An Authentication, Authorization, Accounting (AAA) Remote Authentication Dial-In User Service (RADIUS) client that is
centrally managed, enables user attribution, provides accounting of all user activities, and uses secure standards-
based strong cryptography for authentication and credential protection
• A Role-Based Access Control (RBAC) system that provides a permission model that allows access to UR device
operations and configurations based on specific roles and individual user accounts configured on the AAA server (that
is, Administrator, Supervisor, Engineer, Operator, Observer roles)
• Security event reporting through the Syslog protocol for supporting Security Information Event Management (SIEM)
systems for centralized cybersecurity monitoring
• Strong encryption of all access and configuration network messages between the EnerVista software and UR devices
2
using the Secure Shell (SSH) protocol, the Advanced Encryption Standard (AES), and 128-bit keys in Galois Counter
Mode (GCM) as specified in the U.S. National Security Agency Suite B extension for SSH and approved by the National
Institute of Standards and Technology (NIST) FIPS-140-2 standards for cryptographic systems
Example: Administrative functions can be segmented away from common operator functions, or engineering type access,
all of which are defined by separate roles (see figure) so that access of UR devices by multiple personnel within a
substation is allowed. Permissions for each role are outlined in the next section.

842838A2.CDR
The following types of authentication are supported by CyberSentry to access the UR device:
• Device Authentication (local UR device authenticates)
• Server Authentication (RADIUS server authenticates)
The EnerVista software allows access to functionality that is determined by the user role, which comes either from the local
UR device or the RADIUS server.
The EnerVista software has a device authentication option on the login screen for accessing the UR device. When the
"Device" button is selected, the UR uses its local authentication database and not the RADIUS server to authenticate the
user. In this case, it uses its built-in roles (Administrator, Engineer, Supervisor, Observer, Operator) as login names and the
associated passwords are stored on the UR device. As such, when using the local accounts, access is not user-attributable.
In cases where user-attributable access is required especially to facilitate auditable processes for compliance reasons, use
RADIUS authentication only.
When the "Server" Authentication Type option is selected, the UR uses the RADIUS server and not its local authentication
database to authenticate the user.
No password or security information is displayed in plain text by the EnerVista software or UR device, nor is such
information ever transmitted without cryptographic protection.

The UR samples its AC signals at 64 samples per cycle, that is, at 3840 Hz in 60 Hz systems, and 3200 Hz in 50 Hz systems.
The sampling rate is dynamically adjusted to the actual system frequency by an accurate and fast frequency tracking
system.
The A/D converter has the following ranges of AC signals:
Voltages:
RMS values include harmonics, inter-harmonics, DC components, and so on, along with fundamental frequency values.
The true RMS value reflects thermal effects of the current and is used for the thermal related monitoring and protection
functions.
Protection and control functions respond to phasors of the fundamental and/or harmonic frequency components
(magnitudes and angles), with an exception for some functions that have an option for RMS or fundamental
measurements, or some function responding to RMS only. This type of response is explained typically in each element's
section in the instruction manual.
2 Currents are pre-filtered using a Finite Impulse Response (FIR) digital filter. The filter is designed to reject DC components
and low-frequency distortions, without amplifying high-frequency noise. This filter is referred to as a modified MIMIC filter,
which provides excellent filtering and overall balance between speed and accuracy of filtering. The filter is cascaded with
the full-cycle Fourier filter for the current phasor estimation.
Voltages are pre-filtered using a patented Finite Impulse Response (FIR) digital filter. The filter has been optimized to reject
voltage transformers specific distortions, such as Capacitive Voltage Transformer (CVT) noise and high-frequency
oscillatory components. The filter is cascaded with the half-cycle Fourier filter for the voltage phasor estimation.
The URs measure power system frequency using the Clarke transformation by estimating the period of the waveform from
two consecutive zero-crossings in the same direction (negative-to-positive). Voltage or current samples are pre-filtered
using a Finite Impulse Response (FIR) digital filter to remove high frequency noise contained in the signal. The period is
used after several security conditions are met, such as true RMS signal must be above 6% nominal for a certain time and
others. If these security conditions are not met, the last valid measurement is used for a specific time after which the UR
reverts to nominal system frequency.
Synchrophasors are calculated using a patented convolution integral algorithm. This algorithm allows use of the same
time stamped samples, which are used for protection and taken at the same sampling frequency. This allows URs to use
one sampling clock for both protection algorithms and synchrophasors.
Synchrophasors on firmware versions 7.23 and up have been tested and certified to meet IEEE C.37.118-2011 and
C.37.118.1a-2014 standards for both metering and protection classes with outputs available up to 60 synchrophasors per
second for the metering class and 120 synchrophasors per second for the protection class. Synchrophasors measurement
are also available via IEC 61850-90-5 protocol.
Contact inputs threshold is settable in the firmware with 17, 33, 84, 166 VDC settings available. Inputs are scanned every
0.5 ms and can be conditioned for the critical applications, using debounce time timer, settable from 0.0 ms to 16.0 ms.
Contact inputs with auto-burnishing are available as well, when external contacts are exposed to the contamination in a
harsh industrial environment.
All measured values are available in the UR metering section on the front panel and via communications protocols.
Measured analog values and binary signals can be captured in COMTRADE format with sampling rates from 8 to 64
samples per power cycle. Analog values can be captured with Data Logger, allowing much slower rates extended over
long period of time.
Other advanced UR order code options are available to support IEC 61850 Ed2.0 (including fast GOOSE, MMS server, 61850
services, ICD/CID/IID files, and so on), IEEE 1588 (IEEE C37.238 power profile) based time synchronization, CyberSentry
(advanced cyber security), the Parallel Redundancy Protocol (PRP), IEC 60870-5-103, and so on.

RS422 distance is based on transmitter power and does not take into consideration the clock source provided
by the user.
NOTE
These power budgets are calculated from the manufacturer’s worst-case transmitter power and worst case
receiver sensitivity.
NOTE
The power budgets for the 1300 nm ELED are calculated from the manufacturer's transmitter power and
receiver sensitivity at ambient temperature. At extreme temperatures these values deviate based on
component tolerance. On average, the output power decreases as the temperature is increased by a factor
1 dB / 5 °C.
Typical distances listed are based on the following assumptions for system loss. As actual losses vary from one
installation to another, the distance covered by your system can vary.

Do not touch any rear terminals while the relay is energized, else death or serious injury can
WARNING result from electrical shock.
The small form-factor pluggable ports (SFPs) are pluggable transceivers. Do not use non-validated
NOTICE transceivers or install validated transceivers in the wrong Ethernet slot, else damage can occur.
The relay follows a convention with respect to terminal number assignments, which are three characters long and
assigned by module slot position, row number, and column letter. Two-slot wide modules take their slot designation from
the first slot position (nearest to CPU module), indicated by an arrow marker on the terminal block. The figure shows an
example of rear terminal assignments.

The tables and diagrams on the following pages illustrate the module types (6A and so on) and contact arrangements that
can be ordered for the relay. Since an entire row is used for a single contact output, the name is assigned using the module
slot position and row number. However, since there are two contact inputs per row, these names are assigned by module
slot position, row number, and column position.
Some form-A / solid-state relay outputs include circuits to monitor the DC voltage across the output contact when it is
open, and the DC current through the output contact when it is closed. Each of the monitors contains a level detector
whose output is set to logic “On = 1” when the current in the circuit is above the threshold setting. The voltage monitor is
set to “On = 1” when there is a voltage across open contact (the detector allows a current of about 1 to 2.5 mA), and the
current monitor is set to “On = 1” when the current flowing through the closed contact exceeds about 80 to 100 mA. The
voltage monitor is intended to check the health of the overall trip circuit, and the current monitor can be used to seal-in
the output contact until an external contact has interrupted current flow. If enabled, the current monitoring can be used as
a seal-in signal to ensure that the form-A contact does not attempt to break the energized inductive coil circuit and weld
the output contacts.
3 Block diagrams are shown as follows for form-A and solid-state relay outputs with optional voltage monitor, optional
current monitor, and with no monitoring. The actual values shown for contact output 1 are the same for all contact
outputs. Form-A contact output with or without a current or voltage monitoring option is not polarity sensitive. The polarity
shown in the figure is required for solid-state contact output connection.

The operation of voltage and current monitors is reflected with the corresponding FlexLogic operands (CONT OP # VON, CONT OP
# VOFF, and CONT OP # ION) that can be used in protection, control, and alarm logic. The typical application of the voltage
monitor is breaker trip circuit integrity monitoring; a typical application of the current monitor is seal-in of the control
command.
See the Digital Elements section of chapter 5 for an example of how form-A and solid-state relay contacts can be applied
for breaker trip circuit integrity monitoring.
Consider relay contacts unsafe to touch when the unit is energized. Death or serious injury can
WARNING result from touching live relay contacts.
Where a tilde “~” symbol appears, substitute the slot position of the module. Where a number sign “#” appears,
substitute the contact number.

NOTE
When current monitoring is used to seal-in the form-A and solid-state relay contact outputs, give the
NOTICE FlexLogic operand driving the contact output a reset delay of 10 ms to prevent damage of the output
contact (in situations when the element initiating the contact output is bouncing, at values in the
region of the pickup value).

Regular contact inputs limit current to less than 3 mA to reduce station battery burden. In contrast, contact inputs with 3
auto-burnishing allow currents up to 50 to 70 mA at the first instance when the change of state was sensed. Then, within
25 to 50 ms, this current is slowly reduced to 3 mA as indicated. The 50 to 70 mA peak current burns any film on the
contacts, allowing for proper sensing of state changes. If the external device contact is bouncing, the auto-burnishing
starts when external device contact bouncing is over.
Another important difference between the auto-burnishing input module and the regular input modules is that only two
contact inputs have common ground, as opposed to four contact inputs sharing one common ground (see the Contact
Input and Output Module Wiring diagrams). This is beneficial when connecting contact inputs to separate voltage sources.
Consequently, the threshold voltage setting is also defined per group of two contact inputs.
The auto-burnish feature can be disabled or enabled using the DIP switches found on each daughter card. There is a DIP
switch for each contact, for a total of 16 inputs.
Figure 3-16: Auto-burnish DIP switches
842751A1.CDR
The auto-burnish circuitry has an internal fuse for safety purposes. During regular maintenance, check the auto-burnish
functionality using an oscilloscope.
Transducer output modules provide DC current outputs in several standard DCmA ranges. Software is provided to
configure virtually any analog quantity used in the relay to drive the analog outputs.
Every transducer input/output module has a total of 24 terminal connections. These connections are arranged as three
terminals per row with a total of eight rows. A given row can be used for either inputs or outputs, with terminals in column
"a" having positive polarity and terminals in column "c" having negative polarity. Since an entire row is used for a single
input/output channel, the name of the channel is assigned using the module slot position and row number.
Each module also requires that a connection from an external ground bus be made to terminal 8b. The current outputs
require a twisted-pair shielded cable, where the shield is grounded at one end only. The following figure illustrates the
transducer module types (5A, 5C, 5D, 5E, and 5F) and channel arrangements that can be ordered for the relay.
Where a tilde “~” symbol appears, substitute the slot position of the module.

Lightning strikes and ground surge currents can cause large momentary voltage differences between remote ends of the
communication link. For this reason, surge protection devices are provided internally at both communication ports. An
isolated power supply with an optocoupled data interface also acts to reduce noise coupling. To ensure maximum
reliability, ensure that all equipment has similar transient protection devices installed.
Terminate both ends of the RS485 circuit with an impedance as shown in the figure.

IRIG-B is a standard time code format that allows stamping of events to be synchronized among connected devices. The
IRIG-B code allows time accuracies of up to 100 ns. Using the IRIG-B input, the C30 operates an internal oscillator with 1 µs
resolution and accuracy. The IRIG time code formats are serial, width-modulated codes that can be either DC level shifted
or amplitude modulated (AM). Third party equipment is available for generating the IRIG-B signal; this equipment can use a
global positioning system (GPS) satellite system to obtain the time reference so that devices at different geographic
locations can be synchronized.

The interconnection for dual-channel type 7 communications modules is shown as follows. Two-channel modules allow for
a redundant ring configuration. That is, two rings can be created to provide an additional independent data path. The
required connections are: UR1-Tx1 to UR2-Rx1, UR2-Tx1 to UR3-Rx1, UR3-Tx1 to UR4-Rx1, and UR4-Tx1 to UR1-Rx1 for the
first ring; and UR1-Tx2 to UR4-Rx2, UR4-Tx2 to UR3-Rx2, UR3-Tx2 to UR2-Rx2, and UR2-Tx2 to UR1-Rx2 for the second ring.

The following diagram shows the connection for three UR-series relays using two independent communication channels.
UR1 and UR3 have single type 7 communication modules; UR2 has a dual-channel module. The two communication
channels can be of different types, depending on the type 7 modules used. To allow the direct input and output data to
cross-over from channel 1 to channel 2 on UR2, set the DIRECT I/O CHANNEL CROSSOVER setting to “Enabled” on UR2. This
forces UR2 to forward messages received on Rx1 out Tx2, and messages received on Rx2 out Tx1.

The following figure shows the 64K ITU G.703 co-directional interface configuration.
The G.703 module is fixed at 64 kbps. The SETTINGS PRODUCT SETUP DIRECT I/O DIRECT I/O DATA RATE setting is not
applicable to this module.
AWG 24 twisted shielded pair is recommended for external connections, with the shield grounded only at one end.
Connecting the shield to pin X1a or X6a grounds the shield since these pins are connected internally to ground. Thus, if
pin X1a or X6a is used to ground the shield at one end, do not ground the shield at the other end. This interface module is
protected by surge suppression devices.

In dual loopback mode, the multiplexers are active and the functions of the circuit are divided into two with each receiver/
transmitter pair linked together to deconstruct and then reconstruct their respective signals. Differential Manchester data
enters the Differential Manchester receiver module and then is returned to the differential Manchester transmitter module.
Likewise, G.703 data enters the G.703 receiver module and is passed through to the G.703 transmitter module to be
returned as G.703 data. Because of the complete split in the communications path and because, in each case, the clocks
are extracted and reconstructed with the outgoing data, in this mode there must be two independent sources of timing.
One source lies on the G.703 line side of the interface while the other lies on the differential Manchester side of the
interface.

3.4.5.1 Description
There are two RS422 inter-relay communications modules available: single-channel RS422 (module 7T) and dual-channel
RS422 (module 7W). The modules can be configured to run at 64 kbps or 128 kbps. AWG 20-24 twisted shielded pair cable
is recommended for external connections. These modules are protected by optically-isolated surge suppression devices.
The shield pins (6a and 7b) are connected internally to the ground pin (8a). Proper shield termination is as follows:
• Site 1 — Terminate shield to pins 6a or 7b or both
• Site 2 — Terminate shield to COM pin 2b
Match the clock terminating impedance with the impedance of the line.

The UR-series C37.94 communication module can be connected to the electrical interface (G.703, RS422, or X.21) of a non-
compliant digital multiplexer via an optical-to-electrical interface converter that supports the IEEE C37.94 standard. The
following figure shows the concept.
842756A2.CDR
In 2008, GE Digital Energy released revised modules 76 and 77 for C37.94 communication to enable multi-ended fault
location functionality with firmware 5.60 release and higher. All modules 76 and 77 shipped since the change support this
feature and are fully backward compatible with firmware releases below 5.60. For customers using firmware release 5.60
and higher, the module can be identified with "Rev D" printed on the module and is to be used on all ends of C30
communication for two and three terminal applications. Failure to use it at all ends results in intermittent communication 3
alarms. For customers using firmware revisions below 5.60, it is not required to match the revision of the modules installed.
The UR-series C37.94 communication module has six switches to set the clock configuration. The following figure shows
the functions of these control switches.
Figure 3-43: Switches
Loop timing mode
Internal timing mode (factory default)
842753A2.CDR
For the internal timing mode, the system clock is generated internally. Therefore, set the timing switch selection to internal
timing for relay 1 and loop timed for relay 2. There must be only one timing source configured.
For the looped timing mode, the system clock is derived from the received line signal. Therefore, set the timing selection to
loop timing mode for connections to higher order systems.
The IEEE C37.94 communications module cover removal procedure is as follows:
1. With power to the relay off, remove the IEEE C37.94 module (type 2G, 2H, 2I, 2J, 76, or 77 module) as follows. Record
the original location of the module to help ensure that the same or replacement module is inserted into the correct
slot.
2. Simultaneously pull the ejector/inserter clips located at the top and bottom of each module in order to release the
module for removal.
3. Remove the module cover screw.
4. Remove the top cover by sliding it towards the rear and then lift it upwards.
5. Set the timing selection switches (channels 1 and 2) to the required timing modes (see description earlier).
6. Replace the top cover and the cover screw.
7. Re-insert the IEEE C37.94 module. Take care to ensure that the correct module type is inserted into the correct slot
position. The ejector/inserter clips located at the top and at the bottom of each module must be in the disengaged
position as the module is inserted smoothly into the slot. Once the clips have cleared the raised edge of the chassis,
engage the clips simultaneously. When the clips have locked into position, the module is inserted fully.

• IN SERVICE — This LED indicates that control power is applied, all monitored inputs, outputs, and internal systems are
OK, and that the device has been programmed
• TROUBLE — This LED indicates that the relay has detected an internal problem
• TEST MODE — This LED indicates that the relay is in test mode. For more information, see the Test Mode section in the
Settings chapter.
• TRIP — This LED indicates that the FlexLogic operand serving as a trip switch has operated. This indicator always
latches; as such, a reset command must be initiated to allow the latch to reset.
• ALARM — This LED indicates that the FlexLogic operand serving as an alarm switch has operated. This indicator is
never latched.
• PICKUP — This LED indicates that an element is picked up. This indicator is never latched.
The event-cause indicators in the first column are as follows.
Event-cause LEDs are turned on or off by protection elements that have their respective target setting selected as either
“Enabled” or “Latched.” If a protection element target setting is “Enabled,” then the corresponding event-cause LEDs
remain on as long as the operate operand associated with the element remains asserted. If a protection element target
setting is “Latched,” then the corresponding event-cause LEDs turn on when the operate operand associated with the
element is asserted and remain on until the RESET button on the front panel is pressed after the operand is reset.
All elements that are able to discriminate faulted phases can independently turn off or on the phase A, B, or C LEDs. This
4 includes phase instantaneous overcurrent, phase undervoltage, and so on. This means that the phase A, B, and C operate
operands for individual protection elements are ORed to turn on or off the phase A, B, or C LEDs.
• VOLTAGE — This LED indicates voltage was involved
• CURRENT — This LED indicates current was involved
• FREQUENCY — This LED indicates frequency was involved
• OTHER — This LED indicates a composite function was involved
• PHASE A — This LED indicates phase A was involved
• PHASE B — This LED indicates phase B was involved
• PHASE C — This LED indicates phase C was involved
• NEUTRAL/GROUND — This LED indicates that neutral or ground was involved
In the C30, only the OTHER indicator is applicable and indicates that a digital element was involved.
NOTE
The user-programmable LEDs consist of 48 amber LED indicators in four columns. The operation of these LEDs is user-
defined. Support for applying a customized label beside every LED is provided. Default labels are shipped in the label
package of every C30, together with custom templates. The default labels can be replaced by user-printed labels.
User customization of LED operation is of maximum benefit in installations where languages other than English are used
to communicate with operators. See the User-Programmable LEDs section in chapter 5 for the settings used to program
the operation of the LEDs on these panels.

5.2 Overview
5.2.1 Introduction to elements 5
The main characteristics of an element are shown on a logic diagram. This includes the inputs, settings, fixed logic, and the
output operands generated. The previous chapter explains how to read a logic diagram, and the abbreviations used in a
diagram are defined in the Abbreviations chapter.
• FUNCTION setting — This setting programs the element to operate when selected as “Enabled.” The factory default is
“Disabled.” Once “Enabled,” any element associated with the function becomes active and all options become
available.
• NAME setting — This setting is used to uniquely identify the element.
• PICKUP DELAY setting — This setting sets a time-delay-on-pickup, or on-delay, for the duration between the pickup
and operate output states.
• RESET DELAY setting — This setting is used to set a time-delay-on-dropout, or off-delay, for the duration between the
operate output state and the return to logic 0 after the input transits outside the defined pickup range.
• BLOCK setting — The default output operand state of all comparators is a logic 0 or “flag not set.” The comparator
remains in this default state until a logic 1 is asserted at the RUN input, allowing the test to be performed. If the RUN
input changes to logic 0 at any time, the comparator returns to the default state. The RUN input is used to supervise
the comparator. The BLOCK input is used as one of the inputs to RUN control.
• TARGET setting — This setting is used to define the operation of an element target message. When set to "Disabled,"
no target message or illumination of a faceplate LED indicator is issued upon operation of the element. When set to
“Self-Reset,” the target message and LED indication follow the operate state of the element and self-resets once the
operate element condition clears. When set to “Latched,” the target message and LED indication remains visible after
the element output returns to logic 0 until a RESET command is received by the relay.
• EVENTS setting — This setting is used to control whether the pickup, dropout, or operate states are recorded by the
event recorder. When set to “Disabled,” element pickup, dropout, or operate are not recorded as events. When set to
“Enabled,” events are created for
<Element> PKP (pickup)
<Element> DPO (dropout)
<Element> OP (operate)
The DPO event is created when the measure and decide comparator output transits from the pickup state (logic 1) to
the dropout state (logic 0). This can happen when the element is in the operate state if the reset delay time is not zero.
Not every operand of a given element in a UR relay generates events, only the major output operands. Elements,
asserting output per phase, log operating phase output only, without asserting the common three-phase operand
event.
Lost password
If all passwords are lost, recovery is possible by resetting the unit to default values. Note that the relay is reset to default
5 values, not just the passwords.
To reset the unit after a lost password:
1. Email GE customer service at multilin.tech@ge.com with the serial number and using a recognizable corporate email
account. Customer service provides a code to reset the relay to the factory defaults.
2. Enter the reset code on the front panel, under COMMANDS RELAY MAINTENANCE SERVICE COMMAND.
3. Change the default password of ChangeMe1# as outlined in the Set Up CyberSentry and Change Default Password
section at the end of the Installation chapter.
Password requirements
A user account requires an alpha-numeric password that meets the following requirements:
• Password is case-sensitive
• Password cannot contain the user account name or parts of the user account that exceed two consecutive
characters
• Password must be 6 to 20 characters in length
• Password must contain characters from three of the following four categories:
– English uppercase characters (A through Z)
– English lowercase characters (a through z)
– Base 10 digits (0 through 9)
– Non-alphabetic characters (for example, ~, !, @, #, $,%, &)
A command or setting write operation is required to update the state of the remote and local security
operands listed.
NOTE
PASSWORD ACCESS EVENTS — This setting allows recording of password access events in the event recorder.
As outlined in the previous section, there are two user security access levels, setting and command. Use of a password for
each level controls whether users can enter commands or change settings.
Proper password codes are required to enable each access level. When a CHANGE COMMAND PASSWORD or CHANGE
SETTING PASSWORD setting is programmed to “Yes” via the front panel interface, the following message sequence is
invoked:
5 1. ENTER NEW PASSWORD: ____________.
2. VERIFY NEW PASSWORD: ____________.
3. NEW PASSWORD HAS BEEN STORED.
To gain write access to a “Restricted” setting, program the ACCESS LEVEL setting in the main security menu to “Setting” and
then change the setting, or attempt to change the setting and follow the prompt to enter the programmed password. If the
password is correctly entered, access is allowed. Access automatically reverts to the “Restricted” level according to the
access level timeout setting values and when power is cycled.
If the setting and command passwords are identical, then this one password allows access to both commands
and settings.
NOTE
If a remote connection is established, local passcodes are not visible.
5. Click the OK button. The password is checked to ensure that it meets requirements.
If you establish a local (serial) connection to the relay, you cannot view remote passcodes.

SUPERVISION TIMEOUTS
These settings allow the user to specify the length of inactivity required before returning to the Restricted access level.
Note that the access level is set to Restricted when control power is cycled.
COMMAND LEVEL ACCESS TIMEOUT — This setting specifies the length of inactivity (no local or remote access) required to
return to Restricted access from the Command password level.
SETTING LEVEL ACCESS TIMEOUT — This setting specifies the length of inactivity (no local or remote access) required to return
to Restricted access from the Command password level.
This feature provides a mechanism to prevent unauthorized or unintended upload of settings to a relay through the local
or remote interface.
The following settings are available through the local (front panel) interface only.
• LOCAL SETTING AUTH — This setting is used for local (front panel or RS232 interface) setting access supervision. Valid
values for the FlexLogic operands are either “On” (default) or any physical “Contact Input ~~ On” value.
If this setting is “On,“ then local setting access functions as normal; that is, a local setting password is required. If this
setting is any contact input on FlexLogic operand, then the operand must be asserted (on) prior to providing the local
setting password to gain setting access.
5 If setting access is not authorized for local operation (front panel or RS232 interface) and the user attempts to obtain
setting access, then the UNAUTHORIZED ACCESS message displays on the front panel.
If this setting is "Off," firmware upgrades are blocked. If this setting is "On," firmware upgrades are allowed.
• REMOTE SETTING AUTH — This setting is used for remote (Ethernet or RS485 interface) setting access supervision.
If this setting is “On” (the default setting), then remote setting access functions as normal; that is, a remote password is
required. If this setting is “Off,” then remote setting access is blocked even if the correct remote setting password is
provided. If this setting is any other FlexLogic operand, then the operand must be asserted (set as on) prior to
providing the remote setting password to gain setting access.
If this setting is "Off," firmware upgrades are blocked. If this setting is "On," firmware upgrades are allowed.
• ACCESS AUTH TIMEOUT — This setting represents the timeout delay for local setting access. This setting is applicable
when the LOCAL SETTING AUTH setting is programmed to any operand except “On.” The state of the FlexLogic operand
is monitored continuously for an off-to-on transition. When this occurs, local access is permitted and the timer
programmed with the ACCESS AUTH TIMEOUT setting value is started. When this timer expires, local setting access is
immediately denied. If access is permitted and an off-to-on transition of the FlexLogic operand is detected, the
timeout is restarted. The status of this timer updates every five seconds.
The following settings are available through the remote (EnerVista UR Setup) interface only. Select the Settings > Product
Setup > Security menu item to display the security settings window.
The Remote Settings Authorized setting is used for remote (Ethernet or RS485 interface) setting access supervision. If this
setting is “On” (the default setting), then remote setting access functions as normal; that is, a remote password is required).
If this setting is “Off,” then remote setting access is blocked even if the correct remote setting password is provided. If this
setting is any other FlexLogic operand, then the operand must be asserted (on) prior to providing the remote setting
password to gain setting access.
The Access Authorized Timeout setting represents the timeout delay remote setting access. It applies when the Remote 5
Settings Authorized setting is programmed to any operand except “On” or “Off.” The state of the FlexLogic operand is
continuously monitored for an off-to-on transition. When this occurs, remote setting access is permitted, and the timer
programmed with the Access Authorized Timeout setting value is started. When this timer expires, remote setting access
is denied immediately. If access is permitted and an off-to-on transition of the FlexLogic operand is detected, the timeout
is restarted. The status of this timer updates every five seconds.
2. Enable the Enable Security check box in the lower-left corner to enable the security management system.
3. Click the Ok button.
5 If you force password entry by using this feature, ensure that you know the Administrator password. If you do
not know the password and are locked out of the software, contact GE Digital Energy for the default password
NOTE
of a UR device. When using CyberSentry, the default password is "ChangeMe1#".
Security is now enabled for the EnerVista UR Setup software. Upon starting the software, users are now required to enter a
username and password.
3. Select the user access rights by enabling the check box of one or more fields.
3. Modify the user access rights by enabling or disabling one or more of the check boxes.
When the "Server" Authentication Type is selected, the C30 uses the RADIUS server and not its local authentication
database to authenticate the user.
When the "Device" button is selected, the C30 uses its local authentication database and not the RADIUS server to
authenticate the user. In this case, it uses built-in roles (Administrator, Engineer, Supervisor, Operator, Observer), as login
accounts and the associated passwords are stored on the C30 device. In this case, access is not user-attributable. In cases
where user-attributable access is required, especially for auditable processes for compliance reasons, use server
authentication (RADIUS) only.
No password or security information is displayed in plain text by the EnerVista software or the UR device, nor are they ever
transmitted without cryptographic protection.
Only (TCP/UDP) ports and services that are needed for device configuration and for customer enabled features
NOTE
are open. All the other ports are closed. For example, Modbus is on by default, so its TCP port 502, is open. But if
Modbus is disabled, port 502 is closed. This function has been tested and no unused ports have been found
5
open.
When CyberSentry is enabled, Modbus communications over Ethernet is encrypted, which is not always tolerated by
SCADA systems. The UR has a bypass access feature for such situations, which allows unencrypted Modbus over Ethernet.
This "Bypass Access" setting is available on the SETTINGS PRODUCT SETUP SECURITY SUPERVISORY screen. Note that
other protocols (DNP, 101, 103, 104, EGD) are not encrypted, and they are good communications options for SCADA
systems when CyberSentry is enabled.

LOGIN — This setting is applicable for Device authentication only. This setting allows a user to log in with a specific role, as
outlined here. For the Supervisor role, enable the “Supervisor Role” setting.
Whenever a new role is logged in, the user is prompted to enter a password. Passwords must obey the requirements
specified earlier in the chapter in the Password Requirements section.The UR device supports five roles. Roles have their
corresponding passwords, except the Observer role, which does not require a password.
The roles are defined as follows:
• Administrator — Complete read/write access to all settings and commands. This role does not allow concurrent
access. This role has an operand to indicate when it is logged on.
• Engineer — Complete read/write access to all settings and commands except configuring Security settings and
firmware upgrades. This role does not allow concurrent access.
• Operator — The Operator has read/write access to all settings under the Commands menu/section. This role does not
exist offline.
• Supervisor — This is only an approving role. This role’s authentication commits setting changes submitted by
Administrator or Engineer. The Supervisor role authenticates to unlock the UR relay for setting changes and not
approve changes after the fact. Only a Supervisor can set the Settings Lock and Firmware Lock in the Security
settings. This role also has the ability to forcefully log off any other role and clear the security event log. This role can
also be disabled, but only through a Supervisor authentication. When this role is disabled its permissions are assigned
to the Administrator role.
• Observer — This role has read-only access to all C30 settings. This role allows unlimited concurrent access but it has
no download access to any files on the device. Observer is the default role if no authentication has been done to the
device. This role displays as "None" on the front panel.
The Factory service role is not available. It is for factory use only.
NOTE
The Change Local Passwords menu is shown on the front panel and in EnerVista upon successful login of the Administrator
role.
The LOGIN setting in this menu is similar to that described in SETTINGS > PRODUCT SETUP > SECURITY except for the factory
role.
Passwords are stored in text format. No encryption is applied.
5
In Device authentication mode, the Observer role does not have a password associated with it. In Server
authentication mode the Observer role requires a password.
NOTE
If you are locked out of the software, contact GE Digital Energy for the default password. When using
CyberSentry, the default password is "ChangeMe1#".
Once the passwords are set, the Administrator with Supervisor approval can change the role-associated
password.
In CyberSentry, password encryption is not supported.

authentication with roles is enabled. When this setting is disabled, the UR only authenticates to the AAA server (RADIUS). 5
However, the Administrator and Supervisor (when enabled) remain active even after device authentication is disabled and
their only permission is to re-enable Device authentication. To re-enable Device authentication, the Supervisor unlocks the
device for settings changes, then the Administrator re-enables device authentication.
BYPASS ACCESS — The bypass security feature provides an easier access, with no authentication and encryption for those
special situations when this is considered safe. Only the Supervisor, or the Administrator when the Supervisor role is
disabled, can enable this feature.

Example: If this setting is enabled and an attempt is made to change settings or upgrade the firmware, the UR device
denies the settings changes or denies upgrading the firmware. If this setting is disabled, the UR device accepts settings
changes and firmware upgrade.
This role is disabled by default.
FACTORY SERVICE MODE — When Enabled, the device can go into factory service mode. For this setting to become enabled a
Supervisor authentication is necessary. The default value is Disabled.
SUPERVISOR ROLE — When Enabled, the Supervisor role is active. To Disable this setting a Supervisor authentication is
necessary. If disabled, the Supervisor role is not allowed to log in. In this case, the Administrator can change the settings
under the Supervisory menu.
If enabled, Supervisor authentication is required to change the settings in the Supervisory menu. If the Supervisor disables
their role after authentication, the Supervisor session remains valid until they switch to another role using MMI or until they
end the current Supervisor session if using communications.
This role is disabled by default.
SERIAL INACTIVITY TIMEOUT — The role logged via a serial port is auto logged off after the Serial Inactivity timer times out. A
separate timer is maintained for RS232 and RS485 connections. The default value is 1 minute.

CyberSentry setup
When first using CyberSentry security, use the following procedure for setup.
1. Log in to the relay as Administrator by using the VALUE keys on the front panel to enter the default password
"ChangeMe1#". Note that the Lock Relay setting needs to be disabled in the Security > Supervisory menu. When this
setting is disabled, configuration and firmware upgrade are possible. By default, this setting is disabled.
2. Enable the Supervisor role if you have a need for it.
3. Make any required changes in configuration, such as setting a valid IP address for communication over Ethernet.
4. Log out of the Administrator account by choosing None.
5. Next, Device or Server authentication can be chosen on the login screen, but the choice is available only in EnerVista.
Use Device authentication to log in using the five pre-configured roles (Administrator, Supervisor, Engineer, Operator,
Observer). When using a serial connection, only Device authentication is supported. When Server authentication is
required, characteristics for communication with a RADIUS server must be configured. This is possible only in the
EnerVista software. The RADIUS server itself also must be configured. The appendix called RADIUS Server at the end of
this instruction manual gives an example of how to set up a simple RADIUS server. Once both the RADIUS server and
the parameters for connecting the UR to the server have been configured, you can choose Server authentication on
the login screen of EnerVista.
The use of CyberSentry for devices communicating through an Ethernet-to-RS485 gateway is not
NOTICE supported. Because these gateways do not support the secure protocols necessary to communicate
with such devices, the connection cannot be established. Use the device as a non-CyberSentry
device.
Users logged in through the front panel are not timed out and cannot be forcefully logged out by a
supervisor. Roles logged in through the front panel that do no allow multiple instances (Administrator,
Supervisor, Engineer, Operator) must switch to None (equivalent to a logout) when they are done in
order to log out.
For all user roles except Observer, only one instance can be logged in at a time, for both login by front
panel and software.
To configure Server authentication:
1. In the EnerVista software, choose Device authentication and log in as Administrator.
2. Configure the following RADIUS server parameters: IP address, authentication port, shared secret, and vendor ID.
3. On the RADIUS server, configure the user accounts. Do not use the five pre-defined roles as user names (Administrator,
Supervisor, Engineer, Operator, Observer) in the RADIUS server. If you do, the UR relay automatically provides the
authentication from the device.
4. In the EnerVista software, choose Server authentication and log in using the user name and password configured on
the RADIUS server for Server authentication login.
5. After making any required changes, log out.
When changing settings offline, ensure that only settings permitted by the role that performs the 5
NOTICE settings download are changed because only those changes are applied.
Pushbuttons (both user-control buttons and user-programmable buttons) located on the front panel can be pressed by an
Administrator or Engineer role. This also applies to the RESET button, which resets targets, where targets are errors
displayed on the front panel or the Targets panel of the EnerVista software. The RESET button has special behavior in that it
allows these two roles to press it even when they are logged in through the RS232 port and not through the front panel.
To reset the security event log and self-test operands:
1. Log in as Supervisor (if the role is enabled) or Administrator (if the Supervisor role is disabled) and execute a clear
security command under Commands > Security > Clear Security.

Some relay messaging characteristics can be modified to suit different situations using the display properties settings.
LANGUAGE — This setting selects the language used to display settings, actual values, and targets. This setting displays
when a language other than English was purchased, and the range depends on the order code of the relay.
FLASH MESSAGE TIME — Flash messages are status, warning, error, and information messages displayed in response to
certain key presses during settings programming. These messages override any normal messages. Use this setting to
change the duration of flash messages on the display.
DEFAULT MESSAGE TIMEOUT — If the keypad is inactive for a period of time, the relay automatically reverts to a default
message. The inactivity time is modified using this setting to ensure that messages remain on the screen long enough
during programming or reading of actual values.
DEFAULT MESSAGE INTENSITY — To extend phosphor life in the vacuum fluorescent display, the brightness can be
attenuated during default message display. During keypad interrogation, the display always operates at full brightness.
SCREEN SAVER FEATURE and SCREEN SAVER WAIT TIME — These settings are only visible if the C30 has a liquid crystal display
(LCD) and control its backlighting. When the SCREEN SAVER FEATURE is “Enabled,” the LCD backlighting turns off after the
DEFAULT MESSAGE TIMEOUT followed by the SCREEN SAVER WAIT TIME, provided that no keys have been pressed and no
target messages are active. When a keypress occurs or a target becomes active, the LCD backlighting turns on.
CURRENT CUT-OFF LEVEL — This setting modifies the current cut-off threshold. Very low currents (1 to 2% of the rated value)
are very susceptible to noise. Some customers prefer very low currents to display as zero, while others prefer the current to
display even when the value reflects noise rather than the actual signal. The C30 applies a cut-off value to the magnitudes
and angles of the measured currents. If the magnitude is below the cut-off level, it is substituted with zero. This applies to
phase and ground current phasors as well as true RMS values and symmetrical components. The cut-off operation applies
to quantities used for metering, protection, and control, as well as those used by communications protocols. Note that the
cut-off level for the sensitive ground input is 10 times lower that the CURRENT CUT-OFF LEVEL setting value. Raw current
samples available via oscillography are not subject to cut-off.
VOLTAGE CUT-OFF LEVEL — This setting modifies the voltage cut-off threshold. Very low secondary voltage measurements
(at the fractional volt level) can be affected by noise. Some customers prefer these low voltages to be displayed as zero,
5
while others prefer the voltage to be displayed even when the value reflects noise rather than the actual signal. The C30
applies a cut-off value to the magnitudes and angles of the measured voltages. If the magnitude is below the cut-off level,
it is substituted with zero. This operation applies to phase and auxiliary voltages, and symmetrical components. The cut-off
operation applies to quantities used for metering, protection, and control, as well as those used by communications
protocols. Raw samples of the voltages available via oscillography are not subject to cut-off.
Lower the VOLTAGE CUT-OFF LEVEL and CURRENT CUT-OFF LEVEL with care as the relay accepts lower signals as
valid measurements. Unless dictated otherwise by a specific application, the default settings of “0.02 pu” for
CURRENT CUT-OFF LEVEL and “1.0 V” for VOLTAGE CUT-OFF LEVEL are recommended.
NOTE
Selected records can be cleared from user-programmable conditions with FlexLogic operands. Assigning user-
programmable pushbuttons to clear specific records is a typical application for these commands. Since the C30 responds
to rising edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.
Clearing records with user-programmable operands is not protected by the command password. However, user-
programmable pushbuttons are protected by the command password. Thus, if they are used to clear records, the user-
programmable pushbuttons can provide extra security if required.
For example, to assign user-programmable pushbutton 1 to clear demand records, apply the following settings.
1. Assign the clear demand function to pushbutton 1 by making the following change in the SETTINGS PRODUCT SETUP
CLEAR RELAY RECORDS menu:
CLEAR DEMAND: “PUSHBUTTON 1 ON”
2. Set the properties for user-programmable pushbutton 1 by making the following changes in the SETTINGS PRODUCT

and has settings for baud rate and parity. It is important that these parameters agree with the settings used on the
computer or other equipment that is connected to these ports. Any of these ports can be connected to a computer
running the EnerVista software. This software can download and upload setting files, view measured parameters, and
upgrade the relay firmware. A maximum of 32 relays can be daisy-chained and connected to a DCS, PLC, or computer
using the RS485 ports. If IEC 60870-103 is chosen as the protocol, valid baud rates are 9600 and 19200 bit/s, and valid

As outlined in the previous section, when using more than one Ethernet port, configure each to belong to a different
network or subnet using the IP addresses and mask. Configure the network IP and subnet settings before configuring the
routing settings.
SETTINGS PRODUCT SETUP COMMUNICATIONS NETWORK 1(3)
NETWORK PORT 1 PRT1 IP ADDRESS: Range: standard IPV4 address format
127.0.0.1
The IP addresses are used with the DNP, Modbus/TCP, IEC 61580, IEC 60870-5-104, TFTP, HTTP, and PRP protocols. PRP is
explained in its own section later.
PRT1 (2 or 3) IP ADDRESS — This setting sets the port’s IPv4 address in standard IPV4 format. This setting is valid on port 3 if
port 2 REDUNDANCY is set to None.
PRT1 (2 or 3) SUBNET MASK — This setting sets the port’s IPv4 subnet mask in standard IPV4 format. This setting is valid on
port 3 if port 2 REDUNDANCY is set to None.
PRT2 REDUNDANCY — Determines if ports 2 and 3 operate in redundant or independent mode. If a license for PRP was
purchased, the options are None, Failover, and PRP. If a license for PRP was not purchased, the options are None and
Failover. In non-redundant mode (REDUNDANCY set to None), ports 2 and 3 operate independently with their own MAC, IP,
and mask addresses. If REDUNDANCY is set to Failover, the operation of ports 2 and 3 is as follows:
• Ports 2 and 3 use the port 2 MAC address, IP address, and mask
• The configuration fields for IP address and mask on port 3 are hidden
• Port 3 is in standby mode and does not actively communicate on the Ethernet network but monitors its link to the
Multilink switch. If port 2 detects a problem with the link, communications is switched to Port 3. Port 3 is, in effect,
acting as a redundant or backup link to the network for port 2. Once port 2 detects that the link between itself and the
switch is good and that communication is healthy for five minutes, then switching back to port 2 is performed. The
delay in switching back ensures that rebooted switching devices connected to the C30, which signal their ports as
active prior to being completely functional, have time to completely initialize themselves and become active. Once
port 2 is active again, port 3 returns to standby mode.
If REDUNDANCY is set to PRP, the operation of ports 2 and 3 is as follows:
• Ports 2 and 3 use the port 2 MAC address, IP address, and mask
• The configuration fields for IP address and mask on port 3 are overwritten with those from port 2. This is visible on the
front panel but not displayed in the EnerVista software.
5 • Port 2 MCST ADDRESS field is visible
• The port 2 PTP function still uses only port 2 and the port 3 PTP function still uses only port 3. The relay still
synchronizes to whichever port has the best master. When ports 2 and 3 see the same master, as is typically the case
for PRP networks, the port with the better connectivity is used.
The two ports must be connected to completely independent LANs with no single point of failure, such as
common power supplies that feed switches on both LANs.
NOTE
For any changes to this setting to take effect, restart the unit.
PRT2 PRP MCST ADDR — This setting allows the user to change the multicast address used by the PRP supervision frames.
This setting is available if REDUNDANCY is set to PRP. All devices in the same PRP network need to have the same multicast
address. Choose an address that does not conflict with another multicast protocol.
It is strongly recommended to have switches used for substation automation that support the Far-End Fault feature,
especially when UR 7 redundancy Failover is selected for redundancy.
The C30 is provided with optional PRP capability. This feature is specified as a software option at the time
of ordering. See the Order Codes section in chapter 2 for details.
The Parallel Redundancy Protocol (PRP) defines a redundancy protocol for high availability in substation automation
networks. It applies to networks based on Ethernet technology (ISO/IEC 8802-3) and is based on the second edition (July
2012) of IEC 62439-3, clause 4.
PRP is designed to provide seamless recovery in case of a single failure in the network, by using a combination of LAN
duplication and frame duplication. Identical frames are sent on two completely independent networks that connect source
and destination. Under normal circumstances both frames reach the destination and one of them is sent up the OSI stack
to the destination application, while the second one is discarded. If an error occurs in one of the networks and traffic is
prevented from flowing on that path, connectivity is provided through the other network to ensure continuous
communication. Take care when designing the two LANs, so that no single point of failure (such as a common power
supply) is encountered, as such scenarios can bring down both LANs simultaneously.
Figure 5-7: Example of parallel redundant network
PRP uses specialized nodes called doubly attached nodes (DANPs) for handling the duplicated frames. DANP devices have
an additional module, called a Link Redundancy Entity (LRE). LRE is responsible for duplicating frames and adding the
specific PRP trailer when sending the frames out on the LAN, as well as making decisions on received frames as to which
one is sent up the OSI stack to the application layer and which one is discarded. LRE is responsible for making PRP
transparent to the higher layers of the stack.
In addition, there is a second type of specialized device used in PRP networks, called RedBox, with the role of connecting
Single Attached Nodes (SANs) to a redundant network.
UR relays implement the DANP functionality. The RedBox functionality is not implemented.
The original standard IEC 62439-3 (2010) was amended to align PRP with the High-availability Seamless Redundancy (HSR)
protocol. To achieve this, the original PRP was modified at the cost of losing compatibility with the PRP 2010 version. The
revised standard IEC 62439-3 (2012) is commonly referred to as PRP-1, while the original standard is PRP-0. The UR relays
support PRP-1.
The relay implements PRP on two of its Ethernet ports, specifically Ports 2 and 3 of the CPU module. Use the previous
section (network port configuration) to configure PRP.
PRP is purchased as a separate option. If purchased (valid order code), PRP can be enabled in configuration through a
setting available on the network configuration menu, REDUNDANCY, which already has the capability of enabling failover
redundancy. The options on this setting must be changed to accommodate two types of redundancy: failover and PRP.
When REDUNDANCY is set to either failover or PRP, the ports dedicated for PRP (Ports 2 and 3) operate in redundant mode.
In this mode, Port 3 uses the MAC, IP address, and mask of Port 2.

• The route mask has IP mask format. In binary this needs to be a set of contiguous bits of 1 from left to right, followed
by one or more contiguous bits of 0.
• The route destination and mask must match. This can be verified by checking that
RtDestination and RtMask = RtDestination
Example of good configuration: RtDestination = 10.1.1.0; Rt Mask = 255.255.255.0
Example of bad configuration: RtDestination = 10.1.1.1; Rt Mask = 255.255.255.0
The following rules must be observed when you configure static routes:
• The route destination must not be a connected network
• The route gateway must be on a connected network. This rule applies to the gateway address of the default route as
well. This can be verified by checking that:
(RtGwy & Prt1Mask) == (Prt1IP & Prt1Mask) || (RtGwy & Prt2Mask) == (Prt2IP & Prt2Mask) || (RtGwy & Prt3Mask) == (Prt3IP

The serial communication ports utilize the Modbus protocol, unless the port is configured for DNP or IEC 60870-5-103
operation. This allows the EnerVista UR Setup software to be used on the port. UR devices operate as Modbus slave
devices only.
For more information on the protocol, including the memory map table, see the UR Series Communications Guide.
MODBUS SLAVE ADDRESS — When using the Modbus protocol on the RS232 port, the C30 responds regardless of the
MODBUS SLAVE ADDRESS programmed. For the RS485 port, each device on the serial bus must have a unique slave address
from 1 to 254. Address 0 and addresses from 248 and up are reserved by the Modbus protocol specification, and so their
use here is not recommended. Address 0 is the broadcast address to which all Modbus slave devices listen. When MODBUS
SLAVE ADDRESS is set to 0, the C30 accepts broadcast messages, but in compliance with protocol specifications for
broadcast messages, never replies. Addresses do not have to be sequential, but no two devices can have the same
address or conflicts resulting in errors occur. Generally, starting at 1, set each device added to the link to use the next
higher address. When using Modbus TCP/IP, the client must use the programmed MODBUS SLAVE ADDRESS value in the Unit
Identifier field.
MODBUS TCP PORT NUMBER — Modbus over TCP/IP can also be used on any of the Ethernet ports. The listening TCP port 502
is reserved for Modbus communications, and only in exceptional cases when MODBUS TCP PORT NUMBER is set to any other
port. The MODBUS TCP PORT NUMBER setting sets the TCP port used by Modbus on Ethernet. A MODBUS TCP PORT NUMBER of
0 disables Modbus over TCP/IP, meaning closes the Modbus TCP port. When the port number is changed to 0, the change
takes effect when the C30 is restarted. When it is set to 0, use the front panel or serial port to communicate with the relay.
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.

The Distributed Network Protocol (DNP) allows for the optimization of control and data acquisition between the equipment
in the substation and the central control center. The protocol is scalable; that is, it is designed to be compatible with the
latest high speed LAN technology yet still be implemented over slower speed serial links.
The DNP improves upon many master-slave protocols by improving overall communication performance requirements
and provides time-stamping with millisecond accuracy.
The C30 supports the Distributed Network Protocol (DNP) version 3.0. DNP is enabled when the SETTINGS PRODUCT SETUP
COMMUNICATIONS PROTOCOL setting is set to DNP 3.0. The C30 can be used as a DNP slave device connected to
multiple DNP masters (usually an RTU or a SCADA master station). Since the C30 maintains two sets of DNP data change
buffers and connection information, two DNP masters can actively communicate with the C30 at one time.
See the UR Series Communications Guide for more information on DNP.
The DNP Channels sub-menu is shown.

NONE NETWORK - TCP, NETWORK - UDP
DNP CHANNEL 2 PORT: Range: NONE, COM2 - RS485, FRONT PANEL - RS232,
NONE NETWORK - TCP
The DNP CHANNEL 1 PORT and DNP CHANNEL 2 PORT settings select the communications port assigned to the DNP protocol
for each channel. Once DNP is assigned to a serial port, DNP is the only protocol running on that port; Modbus or IEC
60870-5-103 are disabled. If DNP is assigned to RS485, the protocol must be set to DNP on the serial port configuration as
well, for the change to take effect. When the DNP CHANNEL 1(2) PORT setting is set to “Network - TCP,” the channel 1(2) DNP
protocol can be used over TCP/IP on the Ethernet ports. When this value is set to “Network - UDP,” the DNP protocol can be
used over UDP/IP on channel 1 only.
Changes to these port settings take effect when power has been cycled to the relay.
5 Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.
NOTE
The DNP ADDRESS setting is the DNP slave address. This number identifies the C30 on a DNP communications link. Assign a
unique address to each DNP slave.
The C30 can specify a maximum of five clients for its DNP connections. These are IP addresses for the controllers to which
the C30 can connect. The settings follow.

CLIENT ADDRESSES 0.0.0.0

The DNP TCP/UDP PORT NUMBER setting is for normal DNP operation. To close the port, set the port number to 0. The change
takes effect when the C30 is restarted.
The DNP UNSOL RESPONSE FUNCTION is set to “Disabled” for RS485 applications since there is no collision avoidance
mechanism. The DNP UNSOL RESPONSE TIMEOUT sets the time the C30 waits for a DNP master to confirm an unsolicited
response. The DNP UNSOL RESPONSE MAX RETRIES setting determines the number of times the C30 retransmits an
unsolicited response without receiving confirmation from the master; a value of “255” allows infinite re-tries. The DNP
UNSOL RESPONSE DEST ADDRESS is the DNP address to which all unsolicited responses are sent. The IP address to which
solicited responses are sent is determined by the C30 from the current TCP connection or the most recent UDP message.
The DNP scale factor settings are numbers used to scale analog input point values. These settings group the C30 analog
input data into the following types: current, voltage, power, energy, power factor, and other. Each setting represents the
scale factor for all analog input points of that type. For example, if the DNP VOLTAGE SCALE FACTOR setting is set to “1000,”
all DNP analog input points that are voltages are returned with values 1000 times smaller (for example, a value of 72000 V
on the C30 is returned as 72). These settings are useful when analog input values must be adjusted to fit within certain
ranges in DNP masters. Note that a scale factor of 0.1 is equivalent to a multiplier of 10 (that is, the value is 10 times larger).
The DNP DEFAULT DEADBAND settings determine when to trigger unsolicited responses containing analog input data. These
settings group the C30 analog input data into the following types: current, voltage, power, energy, power factor, and other.
Each setting represents the default deadband value for all analog input points of that type. For example, to trigger
unsolicited responses from the C30 when any current values change by 15 A, the DNP CURRENT DEFAULT DEADBAND setting
is set to “15.” Note that these settings are the deadband default values. DNP object 34 points can be used to change
deadband values, from the default, for each individual DNP analog input point. Whenever power is removed and re-
applied to the C30, the default deadbands are in effect.
The C30 relay does not support power metering. As such, the DNP POWER SCALE FACTOR and DNP POWER
DEFAULT DEADBAND settings are not applicable.
NOTE
The C30 relay does not support energy metering. As such, the DNP ENERGY SCALE FACTOR and DNP ENERGY
DEFAULT DEADBAND settings are not applicable.
NOTE
The DNP TIME SYNC IIN PERIOD setting determines how often the Need Time Internal Indication (IIN) bit is set by the C30.
Changing this time allows the DNP master to send time synchronization commands more or less often, as required.
The DNP MESSAGE FRAGMENT SIZE setting determines the size, in bytes, at which message fragmentation occurs. Large
fragment sizes allow for more efficient throughput; smaller fragment sizes cause more application layer confirmations to
be necessary, which provides more robust data transfer over noisy communication channels.
Check the “DNP Points Lists” C30 web page to view the analog inputs and/or binary inputs points lists. This
page can be viewed with a web browser by entering the IP address of the C30 Ethernet port employed to
5
NOTE
access the C30 Main Menu, then by clicking the Device Information Menu item, then the DNP Points Lists
item.
The DNP OBJECT 1 DEFAULT VARIATION to DNP OBJECT 32 DEFAULT VARIATION settings select the DNP default variation
number for object types 1, 2, 20, 21, 22, 23, 30, and 32. The default variation refers to the variation response when variation
0 is requested and/or in class 0, 1, 2, or 3 scans. See the DNP Implementation section in the UR Series Communications
Guide.
The DNP binary outputs typically map one-to-one to IED data points. That is, each DNP binary output controls a single
physical or virtual control point in an IED. In the C30 relay, DNP binary outputs are mapped to virtual inputs. However, some
legacy DNP implementations use a mapping of one DNP binary output to two physical or virtual control points to support
the concept of trip/close (for circuit breakers) or raise/lower (for tap changers) using a single control point. That is, the DNP
master can operate a single point for both trip and close, or raise and lower, operations. The C30 can be configured to
support paired control points, with each paired control point operating two virtual inputs. The DNP NUMBER OF PAIRED
CONTROL POINTS setting allows configuration of 0 to 32 binary output paired controls. Points not configured as paired
operate on a one-to-one basis.
The DNP TCP CONNECTION TIMEOUT setting specifies a time delay for the detection of dead network TCP connections. If
there is no data traffic on a DNP TCP connection for greater than the time specified by this setting, the connection is
aborted by the C30. This frees up the connection to be re-used by a client. Any change takes effect after cycling power to
the relay.
Up to 256 binary and up to 256 analog input points for the DNP protocol, or the MSP and MME points for IEC 60870-5-104
protocol, can be configured. The value for each point is user-programmable and can be configured by assigning FlexLogic
operands for binary inputs / MSP points or FlexAnalog parameters for analog inputs / MME points.
The menu for the binary input points (DNP) or MSP points (IEC 60870-5-104) follows.

ignored.
The C30 is provided with optional IEC 61850 communications capability. This feature is specified as a
software option at the time of ordering. See the Order Codes section in chapter 2 for details.
The IEC 61850 settings are accessible in EnerVista software or a substation configuration language (SCL) generating tool.
The path is Settings > Product Setup > Communications > IEC 61850. The settings are not accessible from the front panel
of the device.
IEC 61850 messaging can form part of protection schemes. Consider IEC 61850 settings with the same
criticality as protection element settings. To ensure reliable performance of protection schemes utilizing IEC
NOTE
61850 messaging, route IEC 61850 traffic on a separate port from SCADA communications, or use redundant,
independent ports, and a high speed network recovery method, such as PRP.
Overview
IEC 61850 is a series of international standards and technical reports applicable to power utility automation systems. It
includes semantics, abstract communication services, specific communication services, performance specifications,
network engineering guidelines, configuration description methodologies, and engineering processes. The standard
enables interoperability among intelligent electronic devices (IEDs) from different suppliers and interoperability among
software configuration tools from different suppliers. Interoperability in this case is the ability for IEDs to operate on the
same network or communication path sharing information and commands, and for configuration tools to understand
each other's configuration files.
The UR series supports a large subset of IEC 61850 features. These are detailed in the UR Series Communications Guide
and include the information model, GOOSE publish, GOOSE subscribe, buffered report server, unbuffered report server, and
Manufacturing Message Specification (MMS) query, read, write, and control services. In addition, the UR and EnerVista UR
Setup software support IEC 61850 Substation Configuration Language (SCL) file import/export.
Whereas prior UR releases used edition 1.0 of IEC 61850, this release uses edition 2.0, with certain modifications according
to IEC/TR 61850-90-5. Only edition 2.0 61850 configuration tools can interoperate with edition 2.0 devices such as the UR
7.3x release. The UR release uses edition 2.0 SCL, which differs from edition 1.0 SCL. GSSE, fixed GOOSE, and fixed report
services of previous releases are no longer supported, and thus UR devices of previous releases using these features have
to be converted to configurable GOOSE to communicate with a 7.3x device.
Many settings of UR protection, control, and monitoring elements, that is to say elements that are not concerned with the
IEC 61850 protocol, can nevertheless be accessed via IEC 61850. These settings are documented elsewhere in this Settings
5
chapter. This section of the Settings chapter deals solely with the settings that configure the IEC 61850 protocol itself.
The maximum number of simultaneous clients supported by the UR series is five.
The IEC 61850 window is divided into a navigation pane on the left and a settings panel on the right. You expand and click
an option on the left to display its panel on the right. The following figure shows an example for Server Configuration. The
setting entry panel contains in the SETTING column the names of the settings, and the settings entry boxes are in the
PARAMETER column. Hovering the mouse over a setting name displays a tool-tip showing the 61850 information model
name of the setting or its location in SCL files.
5 Figure 5-10: Main IEC 61850 panel
Opening the IEC 61850 window while online causes the UR Setup software to retrieve and import an SCL file from the
connected C30. This SCD file contains all the settings in the UR at the time of the file request, both those that are mapped
into the IEC 61850 information model (that is, the "public" sections) and those that are not in the model (that is, the "private"
section). The UR Setup software imports all of these settings into the current session, not just those in the IEC 61850
window. To avoid loss of any unsaved setting changes made in other panels during the current session, all other panels for
the C30 must be closed before the IEC 61850 panel can be opened; the software prompts for this when applicable. Panels
for other devices can be open concurrently to facilitate parameter coordination.
The Restore button restores all settings in the IEC 61850 window to their last saved values. The Default button causes all
settings in the IEC 61850 window to revert to factory default values. Both buttons affect the current panel being displayed.
Neither button affects settings in other than the IEC 61860 window.
Server configuration
The Server Configuration panel contains IEC 61850 settings relevant to the server functions of the IED implementation.
The path is Settings > Product Setup > Communications > IEC 61850 > Server Configuration.
The following settings are available, where <iedName> is a syntactic variable representing the present value of the IED
NAME setting.
IED NAME 5
Range: 1 to 64 VisibleString characters
Default: TEMPLATE
The value entered sets the IED name used by IEC 61850 for the C30. An IED name unique within the network must be
entered for proper operation. Valid characters are upper and lowercase letters, digits, and the underscore (_) character.
The first character must be a letter.
Master functional ldName
Range: 0 to 64 VisibileString characters
Default:
The Master logical device contains the UR logical nodes modelling communications and setting group control. Valid
characters are upper and lowercase letters, digits, and the underscore (_) character. If the number of characters entered
is greater than zero, this setting sets the name used in communications for the Master logical device. If an ldName is
entered, a name unique within the network must be entered for proper operation. The standard recommends choosing
this name according to IEC 81346-1. If the number of characters entered is zero, the name used in communications for
the Master logical device is "<iedName>Master", where <iedName> is the value of setting IED NAME described earlier.
Throughout the remainder of this section, <LDName> is a syntactic variable representing the present name of
the master logical device. Depending on its context, <LDName> can be a product-related name or a function-
NOTE
related name. In SCL files, <LDName> is always the product-related name. In IEC 61850 messages, <LDName>
is the function-related name if one is set by the Master functional ldName setting, otherwise <LDName> is
again the product-related name. The product-related name of the Master logical device is
"<iedName>Master". The function related name of the Master logical device is the value of the Master
functional ldName setting.
Altitude
Range: 0 to 10,0000 m in steps of 1 m
Default: 0 m
The value entered sets the value of the data attribute <LDName>/LPHD1.PhyNam.altitude. This data attribute is provided
by the protocol to allow the user to declare the geographical position of the device in WGS84 coordinates - altitude.
Prefix for GGIO1
Range: 0 to 7 VisibleString characters
Default:
This setting sets the LN Prefix of the logical node GGIO1 that is described in the GGIO1 section later. Valid characters are
upper and lowercase letters, digits, and the underscore (_) character. The first character must be a letter.
Prefix for GGIO2
Range: 0 to 7 VisibleString characters
Default:
This setting sets the LN Prefix of logical node GGIO2 that is described in the GGIO2 section later. Valid characters are
upper and lowercase letters, digits, and the underscore (_) character. The first character must be a letter.
Prefix for GGIO4
Range: 0 to 7 VisibleString characters
Default:
This setting sets the LN Prefix of logical node GGIO4 that is described in the GGIO4 section later. Valid characters are
upper and lowercase letters, digits, and the underscore (_) character. The first character must be a letter.
Master configRev
Range: 0 to 255 ASCII characters
Default: 5
This data attribute is provided by the protocol to allow the user to declare changes to the semantic of the data model of
the UR. The intent is that the user changes Master configRev each time that the semantic or data model changes, so
that clients can readily detect the change. A semantic change is a logical node getting a new semantic use; for example,
an instance of logical node CSWI is now serving a different physical switch, or an instance of a logical node PDIS is now
used for another zone. A data model change is a change in the presence of logical nodes, data objects, data attributes,
or instance names.
The scope of Maser configRev is the entire relay configuration as the Master logical device is the root logical device.
Similar settings are provided for the other logical nodes; the scope of these other configRev settings is limited to the
corresponding logical device configuration.
paramRev
Range: -2,147,483,648 to 2,147,483,647 in steps of 1
Default: 0
This data attribute is provided by the protocol to make changes to the settings of the C30 apparent to clients. The
Substation Configuration Tool and UR Setup software advance the value of paramRev each time any setting changes.
The C30 increments the value of parmRev when a setting change is made other than through CID file download.
LLN0.Mod.ctlModel
Range: status-only, direct-with-normal-security, sbo-with-normal-security
Default: sbo-with-normal-security
This setting specifies the control service that clients must use to control the TEST MODE FUNCTION of the C30. An "on"
control to <LDName>/LLN0.Mod changes TEST MODE FUNCTION to Disabled, an "on-blocked" control changes it to
Forcible, and a "test/blocked" changes it to Isolated.
IEC/MMS TCP PORT NUMBER
Range: 0 to 65535 in steps of 1
Default: 102
This setting allows the user to change the TCP port number for Manufacturing Message Specification (MMS) connections.
It is recommended that this setting be left at the default value.
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.
NOTE
Configuration Type
Range: G2, E3-2.0
Default: G2
This setting specifies the method used to describe GOOSE subscription configuration in SCL. See the UR Series
Communications Guide for details. Basically, in the G2 mode, the CID file contains IED elements for IEDs subscribed to by
this IED containing GOOSE subscription information. In the E3 2.0 mode, the CID file has only one IED element and
GOOSE subscription information is coded in data objects in the standard LGOS logical node used to monitor reception of
the subscribed GOOSE. UR 7.30 or later accepts either mode.
GOOSE
The path is Settings > Product Setup > Communications > IEC 61850 > GOOSE.
Figure 5-11: IEC 61850 TxGOOSE Access Points panel
TxGOOSE
IEC 61850 GOOSE is an efficient method for simultaneous high-speed delivery of a set of generic substation event
information in a publishing physical device to more than one subscribing physical device. A TxGOOSE is a UR element
implementing a single IEC 61850 GOOSE message publishing service. The subscribing function in URs is performed by
RxGOOSE elements, as described in the next section. Each UR with IEC 61850 order code options has eight TxGOOSE
elements. Each TxGOOSE element can publish the values of up to 64 FlexLogic or FlexAnalog operands in the UR.
Published TxGOOSE messages configured in the EnerVista UR Setup software can be subscribed by and the published
operand values understood by other UR devices. In fact, they can be subscribed to and understood by any device of any
manufacturer that implements the IEC 61850 edition 1.0 or 2.0 GOOSE subscription mechanism. The messages are
published with a multicast address so that the network sends the messages to all devices; any number of devices that
want to subscribe can.
The entities whose values are published in GOOSE messages are known as members. The members are itemized in an
ordered list known as a data set. Each TxGOOSE can use any one of the data sets provided. See the DataSets section later
for details.
Each enabled TxGOOSE transmits its message whenever a value change is detected in one or more of its members. To
guard against the possibility that such a message is lost in the network before it reaches all subscribers, the message is
quickly retransmitted several times. To allow subscribers to verify that their link to the publisher and the publisher itself are
healthy, each message is also periodically retransmitted even while the values are unchanging. These latter messages are
known as heartbeat messages, while the former are known as event messages. Heartbeat messages also provide means
for a subscriber newly online to receive the published values in the absence of an event.
TxGOOSE1 and TxGOOSE2 scan for value changes in its FlexLogic operand members as frequently as such a change can
occur. TxGOOSE1 and TxGOOSE2 are therefore suitable for highly time critical signals, such as tripping and dynamic
blocking. FlexAnalog members are scanned for value changes only every 250 ms. See the Deadband Settings section later
for a description of what is considered a value change in an analog member.
The remaining TxGOOSE, meaning TxGOOSE3 and up, scan both their FlexLogic and FlexAnalog members for value
changes every 250 ms. They are suited for control applications, such as voltage control or power factor regulation.
The details of TxGOOSE message construction are contained in the UR Series Communications Guide. Knowledge of these
details is not required to configure GOOSE.
The UR does not implement the Fixed-Length encoded GOOSE messages option specified in IEC 61850-8-1:2011 clause
A.3; the UR always uses the ASN.1 Basic encoding rules (as specified in ISO/IEC 8825-1) as specified in IEC 61850-8-1:2004
and as optional in IEC 61850-8-1:2011 clause A.3. So do not try to configure the UR for fixed-offset TxGOOSE.
TxGOOSE
Navigate to Settings > Product Setup > Communications > IEC 61850 > GOOSE > TxGOOSE > Access Points to access
the settings that are common to all GOOSE messages published.
The following settings are available.
PORT1 GOOSE ENABLE
Range: Enabled, Disabled 5
Default: Enabled
When set to Disabled, no GOOSE messages are published on C30 Ethernet port 1, and any GOOSE messages received on
port 1 are ignored. When set to Enabled, all enabled GOOSE messages are published on C30 Ethernet port 1, and any
GOOSE messages received on port 1 are listened to.
C30 Ethernet ports 2 and 3 each have a similar setting.
TxGOOSE UPDATE TIME
Range: 1 to 60 s in steps of 1 s
Default: 60 s
This setting specifies the time interval between heartbeat messages, which are messages that are sent periodically
while no events are detected. The standard suggests that the heartbeat time be less than (actually half) of the
timeAllowedtoLive parameter, which is set by the TxGOOSE TIME TO LIVE settings described later.
Navigate to Settings > Product Setup > Communications > IEC 61850 > GOOSE > TxGOOSE > TxGOOSE1 to access the
settings for the first TxGOOSE. The settings and functionality for the others are similar.
TxGOOSE1 FUNCTION
Range: Enabled, Disabled
Default: Enabled
When set to Disabled, TxGOOSE1 messages are not published. When set to Enabled, TxGOOSE1 messages are published.
When TxGOOSE1 to 8 are set to Disabled in EnerVista and subsequently Enabled by writing via MMS, the panel continues
to read Disabled until relaunched. There is no polling capability to update automatically the IEC 61860 readings, so the
panel needs to be closed then opened for the correct status to display.
5 TxGOOSE1 GoID
Range: 0 to 129 VisibleString characters
Default: TxGOOSE1
The entered value sets the goID value published in TxGOOSE1 messages, and can be used by subscribers to discriminate
the TxGOOSE1 messages from other GOOSE messages.
TxGOOSE1 DatSet
Range: None, DataSet01, DataSet02,...
Default: None
This setting selects the published data set using the UR Setup software designator for the data set. The IEC 61850 name
of the data sets are configured in the Datasets panel, as described later.
An ObjectReference to the data set, which consists of the concatenation of the string "<LDName>/LLN0." and the data
set name, is published in the datSet field of TxGOOSE1 messages and can be used by subscribers to discriminate
TxGOOSE1 messages from other GOOSE messages.
TxGOOSE1 DST MAC
Range: any 12 digit hexadecimal number
Default: 01-0C-CD-01-00-00
The value entered sets the Ethernet destination Media Access Control (MAC) address in published TxGOOSE1 messages.
As the standard requires that the address have the multicast bit set TRUE, that is to say the second digit is set to an odd
number, messages transmitted have the multicast bit set TRUE no matter its value in this setting.
The destination MAC address can be used by the network to restrict message delivery to selected devices that need to
receive them, reducing network loading. This address also can be used by hardware in receiving devices to filter out
messages that are of no interest to them, reducing processor burden. Different filtering algorithms are implemented by
different devices. The standard recommends that the algorithm used by hardware of the receiving device be considered
when assigning destination multicast addresses.
Subscribers can use this address to discriminate TxGOOSE1 messages from other GOOSE messages.
Base this setting on the TxGOOSE UPDATE TIME and the tolerable number of contiguous message delivery misses. For
example, if the heartbeat time is 10 s, and missing up to three successive messages is tolerable, make the setting 10*3 +
1 = 31 s. The extra second is to ensure that arrival of the third heartbeat transmission beats the timeAllowedtoLive timer.
The standard suggests that the heartbeat time be less than (actually half) of the timeAllowedtoLive parameter.
RxGOOSE
Navigate to Settings > Product Setup > Communications > IEC 61850 > GOOSE > RxGOOSE > RxGOOSE Messages.
IEC 61850, GOOSE is an efficient method for simultaneous high-speed delivery of the same generic substation event
information in a publishing physical device to more than one subscribing physical device. An RxGOOSE is a UR element
implementing a single IEC 61850 GOOSE message subscribing service. The publishing function in URs is performed by
TxGOOSE elements, as described in the previous section. Each C30 has 32 RxGOOSE elements. Each RxGOOSE element can
subscribe to GOOSE messages from a specified publisher. Subscribed messages can contain up to 64 of any set of data
attributes with basic types BOOLEAN, FLOAT32, INT32, Dbpos, TimeStamp, or Quality. Messages containing data objects,
that is to say structured data, are not accepted.
With these conditions, GOOSE messages from any device of any manufacturer that implements the IEC 61850 edition 1.0
or 2.0 GOOSE publish service can be subscribed to. The UR accepts both the variable-length encoded GOOSE messages
specified in IEC 61850-8-1:2004 and the Fixed-Length encoded GOOSE messages as specified in IEC 61850-8-1:2011
clause A.3.
Each enabled RxGOOSE monitors for interruption of the GOOSE messages that it subscribes to based on the value in the
timeAllowedtoLive field of the last message received. If a new message is not received within that time interval, the
RxGOOSE assumes that connectivity is lost. FlexLogic operands (for example, RxGOOSE1 On, RxGOOSE1 Off) reflect the
status of each RxGOOSE connectivity. RxGOOSE connectivity of an RxGOOSE with non-zero MAC address is also considered
5 lost after the C30 finishes restart until a message is received. When RxGOOSE connectivity is lost, a common RxGOOSE Fail
self-test activates.
Navigate to Settings > Product Setup > Communications > IEC 61850 > GOOSE > RxGOOSE > RxGOOSE Messages >
RxGOOSE1 to access the settings that specify the messages to be accepted by the first RxGOOSE element. Messages that
contain the value true in the ndsCom field are never accepted. Messages that contain the value true in the simulation field
(test field in edition 1.0 messages) are accepted only when the UR test mode is Forcible; see the Testing section at the end
of this chapter for details. The settings and functionality for the other RxGOOSE are similar.
Navigate to Settings > Product Setup > Communications > IEC 61850 > GOOSE > RxGOOSE > RxGOOSE Messages >
RxGOOSE1. The following settings are available.
Figure 5-13: IEC 61850 RxGOOSE Messages panel
RxGOOSE1 ID
Range: 0 to 129 VisibleString characters
Default:
If the value entered has one or more characters, the goID field of incoming GOOSE messages must exactly match this
value for the message to be accepted as a valid RxGOOSE1 message. If the entered value is the empty string, RxGOOSE1
does not check the value received in the goID field.
RxGOOSE1 Dst MAC
Range: any 12 digit hexadecimal number
Default: 00-00-00-00-00-00
Set this setting to the MAC address of the publisher. Only received GOOSE messages having a Media Access Control
(MAC) address equal to this value are accepted as valid RxGOOSE1 messages. An entered address of zero disables
RxGOOSE1.
If the publisher is a UR Series 7.3x device, the setting needs to match the value of the publisher’s TxGOOSE Dst MAC
setting.
RxGOOSE1 ETYPE APPID
Range: 0 to 65535 in steps of 1
Default: 0
If the value entered is non-zero, the APPID field of incoming GOOSE messages must exactly match this value for the
message to be accepted as a valid RxGOOSE1 message. If the value entered is zero, RxGOOSE1 does not check the value
received in the APPID field.
If the publisher is a UR Series 7.3x device, the setting needs to match the value of the publisher’s TxGOOSE ETYPE APPID
setting.
RxGOOSE1 GoCBRef
Range: 0 to 129 alphanumeric, underscore, slash and period characters, beginning with an alpha character
5
Default:
The gocbRef field of incoming GOOSE messages must match this value for the message to be accepted as a valid
RxGOOSE1 message. If the entered value is the empty string, RxGOOSE1 is disabled. If not the empty string, the entry
needs to be an ACSI ObjectReference to the publishing control block in the format:
<LDName>/LLN0.<GoCBName>
where <LDName> is the function-related name if any of the logical device containing the publishing control block,
otherwise the product-related name of that logical device, and <GoCBName> is the name of the publishing control
block.
The C30 translates the ACSI format required for this setting to the MMS format used in GOOSE messages:
<LDName>/LLN0$GO$<GoCBName>
If the publisher is a UR 7.3x series device, <LDName> is the value of the publisher's Master functional ldName setting if
that setting is not empty, otherwise it is the value of the publisher's IED NAME suffixed with "Master". If the publisher is a
UR 7.3x series device, <GoCBName> is "GoCB" suffixed with the two digit TxGOOSE instance number, for example
"GoCB01".
RxGOOSE1 datSet
Range: 0 to 32 alphanumeric and underscore characters, beginning with an alpha character
Default:
If the entered value has one or more characters, the datSet field of incoming GOOSE messages must exactly match this
value prefixed by <LDName>/LLN0$ for the message to be accepted as a valid RxGOOSE1 message. <LDName> is as
specified in the RxGOOSE GoCBRef setting above. If the entered value is the empty string, RxGOOSE1 does not check the
value received in the datSet field.
If the publisher is a UR 7.3x series device, set this setting to the value of the publisher's DataSetxx name setting, where xx
is the instance number of the data set selected by the publisher's TxGOOSE datSet setting.
RxGOOSE1 ConfRev
Range: 0 to 4294967295 in steps of 1
Default: 1
If the value entered is non-zero, the confRev field of incoming GOOSE messages must exactly match this value for the
message to be accepted as a valid RxGOOSE1 message. If the entered value is zero, RxGOOSE1 does not check the value
received in the confRev field.
If the publisher is a UR 7.3x series device, set this setting to match the value of the publisher's TxGOOSE ConfRev setting.
RxGOOSE1 Member 1
Range: End of List, BOOLEAN, Dbpos, FLOAT32, INT32, Quality, TimeStamp
Default: End of List
This setting specifies the type that the first member of incoming GOOSE messages must be for the message to be
accepted as a valid RxGOOSE1 message. There are similar settings for each of the members that the UR is able to
subscribe to in a given GOOSE message. The member before the first member setting set to "End of List" must be the last
member of the message for the message to be accepted as a valid RxGOOSE1 message.
If the publisher is a UR 7.3x series device, set these settings to match the basic type of the members of the publisher's
data set selected by the publisher's TxGOOSE datSet setting.
RxGOOSE inputs
The values received by RxGOOSE elements need to be converted to FlexLogic or FlexAnalog operands so that they can be
used by other UR elements. This conversion is done by RxGOOSE Boolean, RxGOOSE DPS, and RxGOOSE Analog elements.
Each RxGOOSE Boolean can convert the value of a specified Boolean member received by a specified RxGOOSE to a
FlexLogic operand. Each RxGOOSE DPS can convert the value of a specified Dbpos (Double bit position) member to four
FlexLogic operands, one for each of the four possible Dbpos states. Each RxGOOSE Analog can convert the value of a
5 specified FLOAT32 member to a FlexAnalog operand. Each of these operands reverts to its default state when the
RxGOOSE connectivity is lost. INT32, Quality, and TimeStamp members cannot be converted to operands, and thus
although they can be accepted in GOOSE messages, they have no effect on the UR.
RxGOOSE Boolean, RxGOOSE DPS, and RxGOOSE Analog elements are mapped to various data objects in
<iedName>Master/GGIO3. This is to allow reading of their values via MMS and to allow references to them in SCL files.
GGIO3 has no settings, nor is it visible via UR Setup software. See the UR Communications Guide for more information on
GGIO3.
RxGOOSE Boolean1 ID
Range: 0 to 12 characters
Default: RxG Bool1
This setting allows the user to assign descriptive text to the name of the RxGOOSE Boolean1 FlexLogic operand. The full
operand name is the value of this setting appended with " On". This descriptive text also appears in the SCL files
associated with the UR.
RxGOOSE Boolean1 RxGOOSE 5
Range: None, RxGOOSE1, RxGOOSE2, and so on
Default: None
This setting selects the RxGOOSE containing the value that drives the RxGOOSE Boolean1 FlexLogic operand. If set to
None, the RxGOOSE Boolean1 FlexLogic operand assumes its default state.
RxGOOSE Boolean1 Member
Range: 1 to 64 in steps of 1
Default: 1
This setting selects the GOOSE message member that drives the RxGOOSE Boolean1 FlexLogic operand. A setting of 1
selects the first member, 2 selects the second member, and so on. Entering a number greater than the number of
members in the message and entering the number of a member that is not a BOOLEAN results in the RxGOOSE
Boolean1 FlexLogic operand assuming its default state.
RxGOOSE Boolean1 DEFAULT STATE
Range: On, Off, Latest/On, Latest/Off
Default: On
This setting selects the logic state for the RxGOOSE Boolean1 FlexLogic operand if the UR has just completed startup and
the selected RxGOOSE has not yet received a message, or the selected RxGOOSE has lost its connectivity with the
publisher. The following choices are available:
– "On" value defaults the input to logic 1
– "Off" value defaults the input to logic 0
– "Latest/On" freezes the input in case of lost connectivity. If the latest state is unknown, such as after UR power-up
but before the first communication, the input defaults to logic 1. When communication resumes, the input
becomes fully operational.
– "Latest/Off" freezes the input in case of lost connectivity. If the latest state is unknown, such as after UR power-up
but before the first communication, the input defaults to logic 0. When communication resumes, the input
becomes fully operational.
RxGOOSE DPS1 ID
Range: 0 to 12 characters
Default: RxG DPS1
This setting allows the user to assign descriptive text to the names of the four RxGOOSE DPS1 FlexLogic operands. The
full operand name is the value of this setting appended with "Intermediate," "On," "Off," or "Bad." This descriptive text
also appears in the SCL files associated with the C30.
RxGOOSE DPS1 RxGOOSE
Range: None, RxGOOSE1, RxGOOSE2, and so on
Default: None
This setting selects the RxGOOSE containing the value that drives the RxGOOSE DPS1 FlexLogic operand. If set to None,
the RxGOOSE DPS1 FlexLogic operand assumes its default state.
RxGOOSE DPS1 Member
Range: 1 to 64 in steps of 1
Default: 1
This setting selects the GOOSE message member that drives the RxGOOSE DPS1 FlexLogic operand. A setting of 1 selects
the first member, 2 selects the second member, and so on. Entering a number greater than the number of members in
the message and entering the number of a member that is not a Dbpos results in the RxGOOSE DPS1 FlexLogic operand
assuming its default state.
RxGOOSE Analog1 ID
Range: 0 to 12 characters
Default: RxG Analog1
This setting allows the user to assign descriptive text to RxGOOSE Analog1. This descriptive text also appears in the SCL
files associated with the C30. Unlike RxGOOSE Booleans and RxGOOSE DPS, the RxGOOSE Analog operands have fixed
names, for example RxGOOSE Analog1.
5 When the selected RxGOOSE has lost its connectivity with the publisher and this setting is "Last Known," the value of the
RxGOOSE Analog1 FlexLogic operand remains at the last received value. When the selected RxGOOSE has lost its
connectivity with the publisher and this setting value is "Default Value," then the RxGOOSE Analog1 FlexLogic operand is
defined by the RxGOOSE Analog1 DEFAULT setting. After restart, until a message is received, the operand value is the
default value.
RxGOOSE Analog1 UNITS
Range: up to 4 characters
Default:
This setting specifies a four-character string that can is used in the actual values display of RxGOOSE Analog1.
RxGOOSE Analogs are floating-point values, with no units. The RxGOOSE UNIT and PU base settings allow the user to
configure RxGOOSE Analog, so that it can be used in a FlexElement.
RxGOOSE Analogs that represent current, voltage, power, frequency, angles, or power factor can be used in a
FlexElement. The following text must be used in the UNITS setting, to represent these types of analogs: A, V, W, var, VA,
Hz, deg, and no text (blank setting) for power factor.
RxGOOSE Analogs can be compared to other RxGOOSE Analogs with any character string or no string.
RxGOOSE Analog1 PU
Range: 0.000 to 1000000000.000 in steps of 0.001
Default: 1.000
This setting specifies the per-unit base value for other C30 features to use with the RxGOOSE Analog1 operand. A
FlexElement for instance subtracts two quantities after converting their values to integers rescaled to a common base,
the common base being the largest of the base values of the two quantities. If one of quantities is RxGOOSE Analog1 and
its per-unit base value is not appropriate, the rescaling operation can result in unnecessary loss of precision or overflow
in the integer result. The FlexElement Base Units table in the Settings > FlexLogic > FlexElements section later, which
tabulates the per-unit base value used by its pickup setting and implies the per-unit base used by other FlexAnalogs, can
be of use in selecting a value for the RxGOOSE Analog1 PU setting.
Some UR elements have requirements for the type of input operands, for instance current type or voltage type. These
elements assume that RxGOOSE Analog operands are of whatever type is necessary to meet these requirements.
The per-unit base setting represents thousands, not single units. For example, a PU base of 1.000 is actually 1000 and a
PU base of 0.001 is 1.
When using RxGOOSE Analogs and PU base in FlexElements, the largest value that can be displayed in the FlexElement
actual values is 2,140,000.000.
Reports
Navigate to Settings > Product Setup > Communications > IEC 61850 > Reports.
Figure 5-17: IEC 61850 buffered report panel
An IEC 61850 Report server is an efficient method for delivery of generic substation event information in a single server to 5
a single client, such as a supervisory control IED. A Configurable Report is a UR element implementing an IEC 61850 Report
server, either of the buffered or unbuffered kind. The following table lists the number of Configurable Report elements.
Each Configurable Report element can report the values of up to 64 FlexLogic or FlexAnalog operands. Buffered report
elements queue value changes that occur while the client is offline and delivered when the client re-connects. Up to 512
events can be queued. Unbuffered control blocks purge all value change events when the connection to the client is lost;
any events that occur while the client is not connected are lost.
Table 5-9: Number of report elements
Number
Buffered reports 20
Unbuffered reports 14
Configurable Reports interoperate with any client device of any manufacturer that conforms to the IEC 61850 edition 1.0
or 2.0 report client requirements.
The entities whose values are reported by a Configurable Report are known as members. The members are itemized in an
ordered list known as a data set. Each Configurable Report can use any one of the data sets provided that no more than
four data sets are used for reports. This restriction is to limit the amount of processing power that can be allocated to
reporting.
Each enabled Configurable Report transmits an update to its client whenever a value change is detected in one or more of
its members. Also, the control block can be configured to send integrity reports containing the present value of all
members either on demand from the client or periodically. A TCP handshaking mechanism causes messages that are not
read and acknowledged by the client to be retransmitted.
For a Configurable Report to operate, its members must be selected (that is, its data set configured) and a client must open
a connection to, configure, and enable its report control block. Control blocks and data sets can be pre-configured by
sending the C30 a CID file. See the UR Series Communications Guide for details. EnerVista UR Setup also can be used to
select the data set members and to pre-configure the control blocks.
Each buffered report has the following settings.
– conf-revision
Notice that OptFlds bits buffer-overflow and entryID are not applicable to unbuffered reports even though the bits exist
in the protocol. They are therefore labelled N/A (not applicable) on the display.
Unbuffered Report1 BufTm
Range: 0 to 4294967295 in steps of 1
Default: 0
The entered value sets the time interval in milliseconds for the buffering of events for inclusion into a single report.
Unbuffered Report1 TrgOps
Range: The check box for an individual bit can be enabled or not
Default: All bits true
The TrgOps setting is bitstring that controls which trigger conditions are monitored in this report. The options are as
follows:
– data-change
– quality-change
– integrity
– general interrogation
Unbuffered Report1 IntgPd
Range: 0 to 4294967295 in steps of 1.
Default: 0
The entered value sets the period in milliseconds for generating Unbuffered Report1 integrity reports. An integrity report
includes the values of all members of the referenced data set, whether a change has occurred or not.
5 DataSets
Navigate to Settings > Product Setup > Communications > IEC 61850 > DataSets.
As mentioned in the preceding GOOSE and Reports sections, the members whose values are communicated by these
services are itemized in an ordered list known as a data set. Each UR with the IEC 61850 option has 12 data sets. Each data
set can contain as many as 64 members. Any data set can be used simultaneously by any number of TxGOOSE elements
and/or by any number of Configurable Report elements. UR Setup software can configure any FlexLogic operands and any
FlexAnalog operands as members.
Figure 5-19: IEC 61850 DataSets
UR Setup requires data set members to be IEC 61850 data objects or data attributes with Functional Constraint ST or MX.
Certain FlexLogic and FlexAnalog operands have factory assigned data attributes as tabulated in the UR Series
Communications Guide. All FlexLogic and FlexAnalog operands can be user-assigned to GGIO1 or GGIO4 data attributes,
so that operands without factory assigned data attributes can still have their values published. See the GGIO1 and GGIO4
sections later for details.
Datasets used by TxGOOSE1, TxGOOSE2, and/or by reports also provide a chatter suppression service for their Boolean
members. Oscillation in a value, also known as chatter, can be caused by errors in logic programming, inadequate
hysteresis (deadband) on a threshold, or a failed station component. Chatter can flood a communications network with
GOOSE messages, degrading response time for all users. If chatter is detected in a Boolean member, TxGOOSE suspends
GOOSE event message triggering and report message triggering from that member for as long as the condition exists, and
for a minimum period of one second. While sending is suspended, a self-test message identifying the specific data item
detected as oscillating is activated.
Navigate to Settings > Product Setup > Communications > IEC 61850 > DataSets > DataSet01 to access the settings for
the first data set. The settings and functionality for the others are similar.
DataSet01 name
Range: 0 to 32 VisibleString characters
Default: DataSet01
The value entered sets the name of the data set, which is required to be unique within the UR for proper operation. An
ObjectReference to the data set consists of a string that is the concatenation of "<LDName>/LLN0$" and the DataSet01
name setting value. An ObjectReference to the data set is published in the datSet field of TxGOOSE messages, and it can
be used by subscribers to discriminate the messages of that TxGOOSE from other GOOSE messages. An ObjectReference
to the data set is optionally published in the DatSet field of Report messages. Valid characters are upper and lowercase
letters, digits, and the underscore (_) character. The first character must be a letter.
DataSet01 Member1
Range: End of List or any instantiated 61850 data object or data attribute with Functional Constraint ST or MX
Default: End of List
This setting specifies the first member in TxGOOSE1 messages. There is a similar setting for each of the up to 64
members that the UR allows in a Dataset. Only values of members before the first set to End of List are published.
Deadband settings
5
A deadband is a range in which no action occurs, expressed as a percentage.
The IEC 61850 panels contain hundreds of deadband settings, such as in the following panels: System Setup > Signal
Sources, FlexLogic, Grouped Elements, Control Elements, and GGIO4. Each panel is not outlined here.
Deadband setting names all end either with "DEADBAND" or .db. As they all work the same way, but each on a different
analog value, a single description applicable to all deadband settings is given here. The analog value that each deadband
setting applies to is usually obvious from the name of the setting. However, a tabulation of the analog values and their
associated deadband setting can be found in the UR Series Communications Guide.
Figure 5-20: Deadband settings with .db suffix
GOOSE, buffered report, and unbuffered report messages are for the most part transmitted only when there is a value
change in one or more of their members. Most analog values continuously dither by an amount that is not significant.
Were a report to be sent each time an insignificant analog value change occurred, then the communications network
floods with GOOSE and report messages, degrading response time for all users.
To control this, a deadband setting is provided for each analog value. Also, in addition to the present actual value of each
analog ("instMag" in the following figure), there is a deadbanded value ("mag" in the figure), which is updated with the
present value only when the difference between the two exceeds the deadband setting (db in the figure). Changes to this
deadbanded value trigger transmissions when included in GOOSE and report data sets.
Deadband settings are entered in UR Setup in units of percent of the difference between the "max." and "min." of the
associated analog value. A zero deadband setting suppresses transmission triggering. The range of deadband settings is
0.000 to 100.000% in steps of 0.001. The default value is 10.000%.
GGIO4 elements have individual settings for "min." and "max." The min. and max. for FlxEIGAPC#.OpSig.db (FLEXELEMENT #
OpSig) are -50 pu and +50 pu respectively. The min. value for all other quantities is 0. The max. values are as follows:
• Phase current — 46 x phase CT primary setting
• Neutral current — 46 x ground CT primary setting
• Phase and phase-to-phase voltage — 275 x VT ratio setting
• Power (real, reactive, apparent, 3-phase, and 1-phase) — 46 x phase CT primary setting x 275 x VT ratio setting
• Energy (real or imaginary) — 46 x phase CT primary setting x 275 x VT ratio setting x 1 hour
5 • Frequency — 90 Hz
• Frequency rate of change — 90 Hz/s
• Power factor — 2
• Angle — 360 degrees
Select the deadband settings from knowledge of the characteristics of the power system quantity measured and
knowledge of the demands of the applications receiving the measurement via GOOSE or report such that changes of
significance to the application are promptly reported, yet the network is not overly burdened with event messages.
Breaker 1
The UR breaker control and status monitoring elements have certain settings that configure how the IEC 61850 protocol
interacts with these elements. These settings are described in this section. See the Breakers section in the System Setup

GGIO1
GGIO1 is a UR feature that allows up to 128 UR FlexLogic operands to be user-mapped to IEC 61850 information model
data attributes.
For the value of a FlexLogic operand to be read via MMS, included in TxGOOSE messages, or included in buffered/
unbuffered reports, the value must be assigned to a data attribute. GGIO1 allows those FlexLogic operands that have not
yet been factory-assigned to a data attribute to be user-assigned to a generic data attribute, and thus have their values
included in IEC 61850 communications.

NOTE
IEC 60870-5-104 is a transmission protocol for network access, specifically for communication between a control station
and substation over a TCP/IP network.
5 The C30 supports the IEC 60870-5-104 protocol. This protocol is enabled when the SETTINGS PRODUCT SETUP
COMMUNICATIONS PROTOCOL setting is set to IEC 60870-5-104. The C30 can be used as an IEC 60870-5-104 slave device
connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the C30 maintains two
sets of IEC 60870-5-104 data change buffers, ideally no more than two masters actively communicate with the C30 at one
time.
The IEC ------- DEFAULT THRESHOLD settings are used to determine when to trigger spontaneous responses containing
M_ME_NC_1 analog data. These settings group the C30 analog data into types: current, voltage, power, energy, and other.
Each setting represents the default threshold value for all M_ME_NC_1 analog points of that type. For example, to trigger
spontaneous responses from the C30 when any current values change by 15 A, the IEC CURRENT DEFAULT THRESHOLD
setting is set to 15. Note that these settings are the default values of the deadbands. P_ME_NC_1 (parameter of measured
value, short floating point value) points can be used to change threshold values, from the default, for each individual
M_ME_NC_1 analog point. Whenever power is removed and re-applied to the C30, the default thresholds are in effect.
The IEC REDUNDANCY setting decides whether multiple client connections are accepted or not. If redundancy is set to Yes,
two simultaneous connections can be active at any given time.
IEC TCP PORT NUMBER — To close the port, set the port number to 0. The change takes effect when the C30 is restarted.
The C30 relay does not support power metering. As such, the IEC POWER DEFAULT THRESHOLD setting is not

The C30 can specify a maximum of five clients for its IEC 104 connections. These are IP addresses for the controllers to

The C30 is provided with optional Ethernet Global Data (EGD) communications capability. This feature is
specified as a software option at the time of ordering. See the Order Codes section in chapter 2 for
details. 5
Ethernet Global Data (EGD) is a suite of protocols used for the real-time transfer of data for display and control purposes.
The relay can be configured to ‘produce’ EGD data exchanges, and other devices can be configured to ‘consume’ EGD data
exchanges. The number of produced exchanges (up to three), the data items in each exchange (up to 50), and the
exchange production rate can be configured.
The relay supports one fast EGD exchange and two slow EGD exchanges. There are 20 data items in the fast-produced
EGD exchange and 50 data items in each slow-produced exchange.
EGD cannot be used to transfer data between UR series relays. The relay supports EGD production only. An EGD exchange
is not be transmitted unless the destination address is non-zero, and at least the first data item address is set to a valid
Modbus register address. The default setting value of “0” is considered invalid.
Fast exchanges (50 to 1000 ms) are generally used in control schemes. The C30 has one fast exchange (exchange 1) and
two slow exchanges (exchange 2 and 3).
The settings menu for the fast EGD exchange follows.
SETTINGS PRODUCT SETUP COMMUNICATIONS EGD PROTOCOL FAST PROD EXCH 1 CONFIGURATION
FAST PROD EXCH 1 EXCH 1 FUNCTION: Range: Disable, Enable
CONFIGURATION Disable
Slow EGD exchanges (500 to 1000 ms) are generally used for the transfer and display of data items. The settings for the
fast and slow exchanges are as follows.
EXCH 1 DESTINATION — This setting specifies the destination IP address of the produced EGD exchange. This is usually
unicast or broadcast.
EXCH 1 DATA RATE — This setting specifies the rate at which this EGD exchange is transmitted. If the setting is 50 ms, the
exchange data is updated and sent once every 50 ms. If the setting is 1000 ms, the exchange data is updated and sent
once per second. EGD exchange 1 has a setting range of 50 to 1000 ms. Exchanges 2 and 3 have a setting range of 500 to
1000 ms.
5 EXCH 1 DATA ITEM 1 to 20/50 — These settings specify the data items that are part of this EGD exchange. Almost any data
from the C30 memory map can be configured to be included in an EGD exchange. The settings are the starting Modbus
register address for the data item in decimal format. See the Modbus memory map in the UR Series Communications
Guide for details. The Modbus memory map display shows addresses in hexadecimal format. Convert these hex values to
decimal format before entering them as values for these setpoints.
To select a data item to be part of an exchange, it is only necessary to choose the starting Modbus address of the item.
That is, for items occupying more than one Modbus register (for example, 32 bit integers and floating point values), only the
first Modbus address is required. The EGD exchange configured with these settings contains the data items up to the first
setting that contains a Modbus address with no data, or 0. That is, if the first three settings contain valid Modbus addresses
and the fourth is 0, the produced EGD exchange contains three data items.
The C30 is provided with optional IEC 60870-5-103 communications capability. This feature is specified as
a software option at the time of ordering. See the Order Codes section in chapter 2 for details.
IEC 60870-5-103 is a companion standard to the IEC 60870-5 suite of standards for transmission protocols. It defines
messages and procedures for interoperability between protection equipment and devices of a control system in a
substation for communicating on a serial line.
The IEC 60870-5-103 protocol is enabled when the SETTINGS PRODUCT SETUP COMMUNICATIONS PROTOCOL setting
is set to IEC 60870-5-103.
The IEC 60870-5-103 is an unbalanced (master-slave) protocol for coded-bit serial communication, exchanging
information with a control system. In the context of this protocol, the protection equipment is the slave and the control
system is the master. The communication is based on a point-to-point principle. The master must be able to interpret the
IEC 60870-5-103 communication messages.
The UR implementation of IEC 60870-5-103 consists of the following functions:
• Report binary inputs
• Report analog values (measurands)
• Commands
• Time synchronization
The RS485 port supports IEC 60870-5-103.
The UR Series Communications Guide contains more information on the protocol.
IEC103 COMMON ADDRESS OF ASDU — This setting uniquely defines this C30 on the serial line. Select an ID between 0 and
254. This ID does not need to be in sequential order for all stations that communicate with a controller, but it is 5
recommended. Note that RS485 only allows a maximum of 32 slave stations on a communication line, so the entire range
of 254 addresses is never exhausted.
IEC103 SYNC TIMEOUT — This setting defines the time that the C30 waits for a synchronization message. The C30
synchronizes its clock using all available sources, with the source synching more frequently overwriting the time of the
other sources. Since the synchronization message received from the IEC 60870-5-103 master is less frequent than IRIG-B,
PTP, or SNTP, its time is overwritten by these three sources, if any of them is active. If the synchronization timeout occurs
and none of IRIG-B, PTP, or SNTP is active, the C30 sets the invalid bit in the time stamp of a time-tagged message.
The settings for the remaining menus are outlined as follows.
SETTINGS PRODUCT SETUP COMMUNICATIONS IEC 60870-5-103 IEC103 INPUTS BINARY
IEC103 INPUTS POINT 0 See below
BINARY
The binary input points are mapped using elements from a list of possible FlexLogic operands. A maximum of 96 binary
inputs (points) can be mapped this way.
The IEC 60870-5-103 point list always starts with point 0 and ends at the first "Off" value. Since the IEC 60870-5-103 point
list must be in a continuous block, any points assigned after the first "Off" point are ignored.
For each defined point, set appropriate values for the Function Type (FUN) and Information Number (INF), which form the
Information Object Identifier field of the ASDU, as defined in IEC 60870-5-103.
The binary input points are sent as Class 1 data. They are sent either as a response to a general interrogation received
from the controller or reported spontaneously. Spontaneous transmission occurs as a response to cyclic Class 2 requests.
If the C30 wants to transmit Class 1 data at that time, it demands access for Class 1 data transmission (ACD=1 in the
control field of the response).
• If the measured value is larger than what fits in the format defined in IEC 103. The format defined in the standard
allows for signed integers up to 4095. By offsetting, unsigned integers up to 4096 + 4095 = 8191 are supported.
Scaling using factors <1 can be required in such cases. The calculation is outlined in the IEC 60870-5-103 chapter of
the UR Series Communications Guide. Two examples follow, where you decide factors a and b.
Example 1: Nominal power Pn = 100 MW = 100000 KW (power is transmitted in KW)
Since P can be both positive and negative:
Transmitted power Pt = (4095/(Pn*2.4)) * P = (4095/(100000 * 2.4) ) * P
= 0.017 * P
a = 0.017
b=0
Pt = 0.017 * P
For a max power 100000 KW * 2.4 = 240000 KW, we transmit
Pt = 0.017 * 240000 = 4080
A value above 240 MW is indicated by overflow.
COMMAND 1
COMMAND 31
Commands are received as General Command (Type Identification 20). The user can configure the action to perform when
an ASDU command comes.
A list of available mappings is provided on the C30. This includes 64 virtual inputs (see the following table). The ON and OFF
for the same ASDU command can be mapped to different virtual inputs.
Each command is identified by the unique combination made by the function type (FUN) and information number (INF). If
the master sends an ASDU command that does not have the FUN and INF of any configured command, the relay rejects it.

incremented by 1. An address value of “0” in the initial register means “none” and values of “0” display for all registers.
Different ADDRESS values can be entered as required in any of the register positions.

the IP address of the C30 in a web browser and click the option.
The relay contains a real time clock (RTC) to create timestamps for communications protocols as well as for historical data,
such as event records and oscillography. When the relay restarts, the RTC initializes from an onboard battery-backed
clock, which has the same accuracy as an electronic watch, approximately ±1 minute per month (~23 ppm). Once the RTC
is synchronized with the Precision Time Protocol (PTP), IRIG-B, or SNTP, its accuracy approaches that of the synchronizing
time delivered to the relay.
The SYNCHRONIZING SOURCE setting configures the priority sequence of the time synchronization source, to determine
which of the available external time sources to use for time synchronization. A setting of None causes the RTC and the
synchrophasor clock to free-run. A setting of PP/IRIG-B/PTP/SNTP, IRIG-B/PP/PTP/SNTP, or PP/PTP/IRIG-B/SNTP causes the
relay to track the first source named that is enabled and operational, or free-run if none of these are available. Here, PP
means a time source that is strictly compliant with PP, and PTP means a time source that is not strictly compliant with PP.
When a time source fails or recovers, the relay automatically transfers synchronization as required by this setting.
Setup for IRIG-B is illustrated in the Installation chapter.
The clock is updated by all sources active in the device. This means that whenever a time synchronization message is
received through any of the active protocols, the C30 clock updates. However, given that IEC 60870-5-103, IEC 60870-5-
104, Modbus, and DNP are low-accuracy time synchronization methods, avoid their use for synchronization when better
5 accuracy time protocols, such as IRIG-B, PTP, and SNTP, are active in the system.
See the COMMANDS SET DATE AND TIME menu section of this manual to manually set the RTC.
The REAL TIME CLOCK EVENTS setting allows changes to the date and/or time to be captured in the event record. The event
records the RTC time before the adjustment.
To enable IRIG-B synchronization, the input IRIG-B SIGNAL TYPE must be set to DC Shift or Amplitude Modulated. IRIG-B
synchronization can be disabled by making this setting None.
To configure and enable PTP and/or SNTP, or to set local time parameters (for example time zone, daylight savings), use the
following sections.

The C30 is provided with optional Precision Time Protocol capability. This feature is specified as the IEEE
1588 software option at the time of ordering. See the Order Codes section in chapter 2 for details.
The C30 supports the Precision Time Protocol (PTP) specified in IEEE Std 1588 2008 using the Power Profile (PP) specified in
IEEE Std C37.238 2011. This enables the relay to synchronize to the international time standard over an Ethernet network
that implements PP.
The relay can be configured to operate on some PTP networks that are not strictly PP. Time accuracy can be less than
specified for a PP network. Tolerated deviations from strict PP include 1) missing declaration of PP compliance in the
messages, 2) connection to a network device that does not support the PTP peer delay mechanism, 3) jitter substantially
greater than 1 µs in received event messages, and 4) certain non-compliant announce and sync message update rates.
The relay implements PTP according to IEEE Std 1588 2008 and the equivalent IEC 61588:2009(E), sometimes referred to as
version 2 PTP. It does not support the previous version of the standard (version 1).
PTP is a protocol that allows multiple clocks in a network to synchronize with one another. It permits synchronization
accuracies better than 1 ns, but this requires that each and every component in the network achieve very high levels of
accuracy and a very high baud rate, faster than normally used for relay communications. When operating over a generic
Ethernet network, time error can amount to 1 ms or more. PP is a profile of PTP which specifies a limited subset of PTP
suitable for use in power system protection, control, automation, and data communication applications, and thereby
facilitates interoperability between different vendor’s clocks and switches. PP specifies a worst-case delivered time error of 5
less than 1 µs over a 16-hop network.
In a PTP system and in a PP system, the clocks automatically organize themselves into a master-slave synchronization
hierarchy with the “best” clock available making itself the "grandmaster" at the top of the hierarchy; all others make
themselves “slaves” and track the grandmaster. Typically the grandmaster clock receives its time from GPS satellites or
some other link to the international time standard. If the grandmaster fails, the next “best” clock available in the domain
assumes the grandmaster role. When a clock on start-up discovers that it is “better” than the present grandmaster, it
assumes the grandmaster role and the previous grandmaster reverts to slave.
Time messages issued by the grandmaster are delayed as they pass through the network both due to the finite speed of
the signal in the interconnecting fiber or wire, and due to processing delays in the Ethernet switches. Each clock and switch
implementing PP measures the propagation delay to each of its PP neighbors, and compensates for these delays in the
time received. Each network device implementing PP measures the processing delay it introduces in each time message
and compensates for this delay in the time it transmits. As a result, the time delivered to end-devices such as the UR are
virtually identical to the grandmaster time. If one of the network devices in the hierarchy does not fully implement PP, the
associated propagation delay and/or latency may not be compensated for, and the time received at the end-device can be
in error by more than 100 µs.
See the preceding Real Time Clock section for a description of when time values received via PTP are used to update the
relay’s real time clock.
The following settings are available for configuring the relay for PTP. The PTP menu displays only when the option was
purchased.
STRICT POWER PROFILE — Power profile (IEEE Std C37.238 2011) requires that the relay only select a power profile compliant
clock as a grandmaster, that the delivered time have worst-case error of ±1 µs, and that the peer delay mechanism be
implemented. With the strict power profile setting enabled, the relay only selects as master the clocks displaying the
IEEE_C37_238 identification codes. It uses a port only when the peer delay mechanism is operational. With the strict power
profile setting disabled, the relay uses clocks without the power profile identification when no power profile clocks are
present, and uses ports even if the peer delay mechanism is non-operational. This setting applies to all of the relay’s PTP
capable ports.
PTP DOMAIN NUMBER — Set this setting to the domain number of the grandmaster-capable clock(s) to be synchronized to. A
network can support multiple time distribution domains, each distinguished with a unique domain number. More
commonly, there is a single domain using the default domain number zero.
This setting applies to all of the relay’s PTP capable ports.
PTP VLAN PRIORITY — This setting selects the value of the priority field in the 802.1Q VLAN tag in request messages issued
by the relay’s peer delay mechanism. In compliance with PP the default VLAN priority is 4, but it is recommended that it be
set to 7 in accordance with PTP. Depending on the characteristics of the device to which the relay is linked directly, VLAN
Priority can have no effect.
This setting applies to all of the relay’s PTP capable ports.
PTP VLAN ID — This setting selects the value of the ID field in the 802.1Q VLAN tag in request messages issued by the relay’s
peer delay mechanism. It is provided in compliance with PP. As these messages have a destination address that indicates
they are not to be bridged, their VLAN ID serves no function, and so can be left at its default value. Depending on the
characteristics of the device to which the relay is linked directly, VLAN ID can have no effect. This setting applies to all of
the relay’s PTP capable ports.
PORT 1 ... 3 FUNCTION — While this port setting is selected to disabled, PTP is disabled on this port. The relay does not
generate or listen to PTP messages on this port.
PORT 1 ... 3 PATH DELAY ADDER — The time delivered by PTP is advanced by the time value in this setting prior to the time
being used to synchronize the relay’s real time clock. This is to compensate to the extent practical for time delivery delays
not compensated for in the network. In a fully compliant PP network, the peer delay and the processing delay mechanisms
compensate for all the delays between the grandmaster and the relay. In such networks, make this setting zero.
In networks containing one or more switches and/or clocks that do not implement both of these mechanisms, not all
delays are compensated, so the time of message arrival at the relay is later than the time indicated in the message. This
setting can be used to approximately compensate for this delay. However, as the relay is not aware of network switching
5 that dynamically changes the amount of uncompensated delay, there is no setting that always and completely corrects
for uncompensated delay. A setting can be chosen that reduces the worst-case error to half of the range between
minimum and maximum uncompensated delay, if these values are known.
PORT 1 ... 3 PATH DELAY ASSYMMETRY — This setting corresponds to “delayAsymmetry” in PTP, which is used by the peer delay
mechanism to compensate for any difference in the propagation delay between the two directions of a link. Except in
unusual cases, the two fibers are of essentially identical length and composition, so make this setting zero.
In unusual cases where the length of the link is different in different directions, set this setting to the number of
nanoseconds the Ethernet propagation delay to the relay is longer than the mean of path propagation delays to and from
the relay. For instance, if it is known say from the physical length of the fibers and the propagation speed in the fibers that
the delay from the relay to the Ethernet switch it is connected to is 9000 ns and that the delay from the switch to the relay
is 11000 ns, then the mean delay is 10000 ns, and the path delay asymmetry is 11000 - 10000 = +1000 ns.
The C30 supports the Simple Network Time Protocol specified in RFC-2030. With SNTP, the C30 can obtain clock time over
an Ethernet network. The C30 acts as an SNTP client to receive time values from an SNTP/NTP server, usually a dedicated
product using a GPS receiver. UR series relays support unicast, broadcast, multicast, and anycast SNTP functionality.
The SNTP FUNCTION setting enables or disables the SNTP feature on the C30.
To use SNTP in unicast mode, set SNTP SERVER IP ADDR to the SNTP/NTP server IP address. Once this address is set and SNTP
FUNCTION is “Enabled,” the C30 attempts to obtain time values from the SNTP/NTP server. Since many time values are
obtained and averaged, it generally takes three to four minutes until the C30 clock is closely synchronized with the SNTP/
NTP server. It takes up to two minutes for the C30 to signal an SNTP self-test error if the server is offline.
To use SNTP in broadcast mode, set the SNTP SERVER IP ADDR setting to “0.0.0.0” and SNTP FUNCTION to “Enabled.” The C30
then listens to SNTP messages sent to the “all ones” broadcast address for the subnet. The C30 waits up to 18 minutes
(>1024 seconds) without receiving an SNTP broadcast message before signaling an SNTP self-test error.
The SNTP UDP PORT NUMBER is 123 for normal SNTP operation. If SNTP is not required, close the port by setting the port
number to 0, after which the change takes effect when the C30 is restarted.
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.

The real-time clock (RTC) and timestamps reported in historical records and communication protocols can be incorrect if
the Local Time settings are not configured properly.
LOCAL TIME OFFSET FROM UTC — Used to specify the local time zone offset from UTC (Greenwich Mean Time) in hours. Time
zones in the eastern hemisphere have positive values; time zones in the western hemisphere have negative values. A value
of zero causes the relay to use UTC for local time. This setting has two uses. When the system RTC is synchronized with a
communications protocol providing only local time or it is free-running, the offset setting is used to calculate UTC from the
local time these provide. When the RTC is synchronized with a communications protocol providing only UTC (such as PTP or
SNTP), the time offset setting is used to determine local time from the UTC provided. PTP
ALTERNATE_TIME_OFFSET_INDICATOR TLVs are not used to calculate local time. When a communications protocol other
than PTP provides UTC to local time offset (meaning IRIG-B), that offset is used instead of the local time and daylight time
settings.
DAYLIGHT SAVINGS TIME and DST — Can be used to allow the relay to follow the DST rules of the local time zone. Note that
when IRIG-B time synchronization is active, the local time in the IRIG-B signal contains any daylight savings time offset and
so the DST settings are ignored.

SETTINGS PRODUCT SETUP OSCILLOGRAPHY
OSCILLOGRAPHY NUMBER OF RECORDS: Range: 1 to 64 in steps of 1
15
Oscillography records contain waveforms captured at the sampling rate as well as other relay data at the point of trigger.
Oscillography records are triggered by a programmable FlexLogic operand. Multiple oscillography records can be captured
simultaneously.
The NUMBER OF RECORDS is selectable, but the number of cycles captured in a single record varies considerably based on
other factors, such as sample rate and the number of operational modules. There is a fixed amount of data storage for
oscillography; the more data captured, the less the number of cycles captured per record. See the ACTUAL VALUES
RECORDS OSCILLOGRAPHY menu to view the number of cycles captured per record. The following table provides sample
configurations with corresponding cycles/record. The minimum number of oscillographic records is three.

TRIGGER MODE — A new record automatically overwrites an older record when TRIGGER MODE is set to “Automatic
Overwrite.”
TRIGGER POSITION — Set this to a percentage of the total buffer size (for example, 10%, 50%, 75%, and so on). A trigger
position of 25% consists of 25% pre- and 75% post-trigger data.
TRIGGER SOURCE — Always captured in oscillography and can be any FlexLogic parameter (element state, contact input,
virtual output, and so on). The relay sampling rate is 64 samples per cycle.
AC INPUT WAVEFORMS — Determines the sampling rate at which AC input signals (that is, current and voltage) are stored.
Reducing the sampling rate allows longer records to be stored. This setting has no effect on the internal sampling rate of
the relay, which is always 64 samples per cycle. That is, it has no effect on the fundamental calculations of the device.
When changes are made to the oscillography settings, all existing oscillography records are cleared.
NOTE
DIGITAL 1(63) CHANNEL — This setting selects the FlexLogic operand state recorded in an oscillography trace. The length of
each oscillography trace depends in part on the number of parameters selected here. Parameters set to “Off” are ignored.
These settings select the metering actual value recorded in an oscillography trace. The length of each oscillography trace
depends in part on the number of parameters selected here. Parameters set to “Off” are ignored. The parameters available
in a given relay depend on
• the type of relay,
• the type and number of CT/VT hardware modules installed, and
• the type and number of analog input hardware modules installed
A list of all possible analog metering actual value parameters is presented in Appendix A: FlexAnalog Parameters. The
parameter index number shown in any of the tables is used to expedite the selection of the parameter on the relay display.
It can be time-consuming to scan through the list of parameters via the relay keypad and display — entering this number
via the relay keypad causes the corresponding parameter to display.
All eight CT/VT module channels are stored in the oscillography file. The CT/VT module channels are named as follows:
<slot_letter><terminal_number>—<I or V><phase A, B, or C, or 4th input>
The fourth current input in a bank is called IG, and the fourth voltage input in a bank is called VX. For example, F2-IB
designates the IB signal on terminal 2 of the CT/VT module in slot F.
If there are no CT/VT modules and analog input modules, no analog traces appear in the file; only the digital traces appear.
DATA LOGGER CONFIG: Range: Not applicable - shows computed data only
0 CHNL x 0.0 DAYS
The data logger samples and records up to 16 analog parameters at a user-defined sampling rate. This recorded data can
be downloaded to EnerVista UR Setup and displayed with parameters on the vertical axis and time on the horizontal axis.
All data is stored in non-volatile memory, so the information is retained when power to the relay is lost.
For a fixed sampling rate, the data logger can be configured with a few channels over a long period or a larger number of
channels for a shorter period. The relay automatically partitions the available memory between the channels in use. The
following table outlines examples of storage capacities for a system frequency of 60 Hz.

Changing any setting affecting data logger operation clears data in the log.
NOTE
DATA LOGGER MODE — This setting configures the mode in which the data logger operates. When set to “Continuous,” the
data logger actively records any configured channels at the rate as defined by the DATA LOGGER RATE. The data logger is
idle in this mode when no channels are configured. When set to “Trigger,” the data logger records any configured channels
at the instance of the rising edge of the DATA LOGGER TRIGGER source FlexLogic operand. The data logger ignores all
subsequent triggers and continues to record data until the active record is full. Once the data logger is full, a CLEAR DATA
LOGGER command is required to clear the data logger record before a new record can be started. Performing the CLEAR
DATA LOGGER command also stops the current record and resets the data logger to be ready for the next trigger.
DATA LOGGER TRIGGER — This setting selects the signal used to trigger the start of a new data logger record. Any FlexLogic
operand can be used as the trigger source. This setting only applies when the mode is set to “Trigger.”
DATA LOGGER RATE — This setting selects the time interval at which the actual value data is recorded.
DATA LOGGER CHNL 1(16) — This setting selects the metering actual value that is to be recorded in Channel 1(16) of the data
log. The parameters available in a given relay are dependent on: the type of relay, the type and number of CT/VT hardware
modules installed, and the type and number of Analog Input hardware modules installed. Upon startup, the relay
automatically prepares the parameter list. A list of all possible analog metering actual value parameters is shown in
Appendix A: FlexAnalog Parameters. The parameter index number shown in any of the tables is used to expedite the
selection of the parameter on the relay display. It can be time-consuming to scan through the list of parameters via the
relay keypad/display—entering this number via the relay keypad causes the corresponding parameter to display.

SETTINGS PRODUCT SETUP USER-PROGRAMMABLE LEDS
USER-PROGRAMMABLE LED TEST See below
LEDS
When enabled, the LED test can be initiated from any digital input or user-programmable condition, such as a user-
programmable pushbutton. The control operand is configured under the LED TEST CONTROL setting. The test covers all
LEDs, including the LEDs of the optional user-programmable pushbuttons.
The test consists of the following three stages:
1. All 62 LEDs on the relay are illuminated. This is a quick test to verify if any of the LEDs is “burned.” This stage lasts as
long as the control input is on, up to a maximum of 1 minute. After 1 minute, the test ends.
2. All the LEDs are turned off, and then one LED at a time turns on for 1 second, then back off. The test routine starts at
the top left panel, moving from the top to bottom of each LED column. This test checks for hardware failures that lead
to more than one LED being turned on from a single logic point. This stage can be interrupted at any time.
3. All the LEDs are turned on. One LED at a time turns off for 1 second, then back on. The test routine starts at the top left
panel moving from top to bottom of each column of the LEDs. This test checks for hardware failures that lead to more
than one LED being turned off from a single logic point. This stage can be interrupted at any time.
When testing is in progress, the LEDs are controlled by the test sequence, rather than the protection, control, and
monitoring features. However, the LED control mechanism accepts all the changes to LED states generated by the relay
and stores the actual LED states (on or off) in memory. When the test completes, the LEDs reflect the actual state resulting
from relay response during testing. The reset pushbutton does not clear any targets when the LED Test is in progress.
A dedicated FlexLogic operand, LED TEST IN PROGRESS, is set for the duration of the test. When the test sequence is initiated,
the LED TEST INITIATED event is stored in the event recorder.
The entire test procedure is user-controlled. In particular, stage 1 can last as long as necessary, and stages 2 and 3 can be
interrupted. The test responds to the position and rising edges of the control input defined by the LED TEST CONTROL
setting. The control pulses must last at least 250 ms to take effect. The following diagram explains how the test is
executed.

Application example 1
Assume one needs to check if any of the LEDs is “burned” through user-programmable pushbutton 1. Apply the following
settings.
Configure user-programmable pushbutton 1 by making the following entries in the SETTINGS PRODUCT SETUP USER-
PROGRAMMABLE PUSHBUTTONS USER PUSHBUTTON 1 menu. (The option does not display when not purchased.)
PUSHBUTTON 1 FUNCTION: “Self-reset”
PUSHBTN 1 DROP-OUT TIME: “0.10 s”
Configure the LED test to recognize user-programmable pushbutton 1 by making the following entries in the SETTINGS
PRODUCT SETUP USER-PROGRAMMABLE LEDS LED TEST menu:
LED TEST FUNCTION: “Enabled”
LED TEST CONTROL: “PUSHBUTTON 1 ON”
The test is initiated when the user-programmable pushbutton 1 is pressed. Keep the pushbutton pressed for as long as the
LEDs are being visually inspected. When finished, release the pushbutton. The relay then automatically starts stage 2. At
this point, test can be cancelled by pressing the pushbutton.
Application example 2
Assume one needs to check if any LEDs are “burned” as well as exercise one LED at a time to check for other failures. This
is to be performed via user-programmable pushbutton 1.
After applying the settings in application example 1, hold down the pushbutton as long as necessary to test all LEDs. When
finished, release the pushbutton so that the relay then automatically starts stage 2. When stage 2 is completed, stage 3
starts automatically. The test can be cancelled at any time by pressing the pushbutton.
The trip and alarm LEDs are in the first LED column (enhanced faceplate) and on LED panel 1 (standard faceplate). Each
indicator can be programmed to become illuminated when the selected FlexLogic operand is in the logic 1 state.
There are 48 amber LEDs across the relay faceplate LED panels. Each of these indicators can be programmed to illuminate
when the selected FlexLogic operand is in the logic 1 state.
For the standard faceplate, the LEDs are located as follows:
• LED Panel 2 — User-programmable LEDs 1 through 24
• LED Panel 3 — User programmable LEDs 25 through 48
For the enhanced faceplate, the LEDs are located as follows:
• LED column 2 — User-programmable LEDs 1 through 12
• LED column 3 — User-programmable LEDs 13 through 24
• LED column 4 — User-programmable LEDs 25 through 36
• LED column 5 — User-programmable LEDs 37 through 48
See the LED Indicators section in chapter 4 for information on the location of these indexed LEDs.
The user-programmable LED settings select the FlexLogic operands that control the LEDs. If the LED 1 TYPE setting is “Self-
Reset” (the default setting), the LED illumination tracks the state of the selected LED operand. If the LED 1 TYPE setting is
“Latched,” the LED, once lit, remains so until reset by the faceplate RESET button, from a remote device via a
communications channel, or from any programmed operand, even if the LED operand state de-asserts.
All major self-test alarms are reported automatically with their corresponding FlexLogic operands, events, and targets.
Most of the minor alarms can be disabled if so wanted.
When in the Disabled mode, minor alarms do not assert a FlexLogic operand, write to the event recorder, or display target
messages. Moreover, they do not trigger the ANY MINOR ALARM or ANY SELF-TEST messages. When in Enabled mode,
minor alarms continue to function along with other major and minor alarms. See the Relay Self-tests section in chapter 7
for information on major and minor self-test alarms.
There are three standard control pushbuttons, labeled USER 1, USER 2, and USER 3, on the standard and enhanced front
panels. These are user-programmable and can be used for various applications such as performing an LED test, switching
setting groups, and invoking and scrolling though user-programmable displays.
The location of the control pushbuttons are shown in the following figures.

USER 4
842733A2.CDR
Control pushbuttons are not typically used for critical operations and are not protected by the control password. However,
by supervising their output operands, the user can dynamically enable or disable control pushbuttons for security reasons.
Each control pushbutton asserts its own FlexLogic operand. Each operand need to be configured appropriately to perform
the required function. Each operand remains asserted as long as the pushbutton is pressed and resets when the
pushbutton is released. A dropout delay of 100 ms is incorporated to ensure fast pushbutton manipulation is recognized
by various features that can use control pushbuttons as inputs.
An event is logged in the event record (as per user setting) when a control pushbutton is pressed. No event is logged when
the pushbutton is released. The faceplate keys (including control keys) cannot be operated simultaneously—a given key
must be released before the next one can be pressed.

order code for your device, see the order codes in chapter 2 for details.
User-programmable pushbuttons provide an easy and error-free method of entering digital state (on, off) information. The
number of available pushbuttons is dependent on the faceplate module ordered with the relay.
• Type P faceplate: standard horizontal faceplate with 12 user-programmable pushbuttons
• Type Q faceplate: enhanced horizontal faceplate with 16 user-programmable pushbuttons
The digital state can be entered locally (by directly pressing the front panel pushbutton) or remotely (via FlexLogic
operands) into FlexLogic equations, protection elements, and control elements. Typical applications include breaker
control, autorecloser blocking, and setting groups changes. The user-programmable pushbuttons are under the control
level of password protection.

Both the standard and enhanced faceplate pushbuttons can be custom labeled with a factory-provided template,
available online at http://www.gedigitalenergy.com/multilin. The EnerVista software can also be used to create labels for
the enhanced faceplate.
Each pushbutton asserts its own “On” and “Off” FlexLogic operands (for example, PUSHBUTTON 1 ON and PUSHBUTTON 1 OFF).
These operands are available for each pushbutton and are used to program specific actions. If any pushbutton is active,
the ANY PB ON operand is asserted.
Each pushbutton has an associated LED indicator. By default, this indicator displays the present status of the
corresponding pushbutton (on or off). However, each LED indicator can be assigned to any FlexLogic operand through the
PUSHBTN 1 LED CTL setting.
The pushbuttons can be automatically controlled by activating the operands assigned to the PUSHBTN 1 SET (for latched
and self-reset mode) and PUSHBTN 1 RESET (for latched mode only) settings. The pushbutton reset status is declared when
the PUSHBUTTON 1 OFF operand is asserted. The activation and deactivation of user-programmable pushbuttons is dependent
on whether latched or self-reset mode is programmed.
• Latched mode — In latched mode, a pushbutton can be set (activated) by asserting the operand assigned to the
PUSHBTN 1 SET setting or by directly pressing the associated front panel pushbutton. The pushbutton maintains the set
state until deactivated by the reset command or after a user-specified time delay. The state of each pushbutton is
stored in non-volatile memory and maintained through a loss of control power.
The pushbutton is reset (deactivated) in latched mode by asserting the operand assigned to the PUSHBTN 1 RESET
setting or by directly pressing the associated active front panel pushbutton.
It can also be programmed to reset automatically through the PUSHBTN 1 AUTORST and PUSHBTN 1 AUTORST DELAY
settings. These settings enable the autoreset timer and specify the associated time delay. The autoreset timer can be
used in select-before-operate (SBO) breaker control applications, where the command type (close/open) or breaker
location (feeder number) must be selected prior to command execution. The selection must reset automatically if
control is not executed within a specified time period.
• Self-reset mode — In self-reset mode, a pushbutton remains active for the time it is pressed (the pulse duration) plus
the dropout time specified in the PUSHBTN 1 DROP-OUT TIME setting. If the pushbutton is activated via FlexLogic, the
pulse duration is specified by the PUSHBTN 1 DROP-OUT TIME only. The time the operand remains assigned to the
PUSHBTN 1 SET setting has no effect on the pulse duration.
The pushbutton is reset (deactivated) in self-reset mode when the dropout delay specified in the PUSHBTN 1 DROP-OUT
TIME setting expires.
The pulse duration of the remote set, remote reset, or local pushbutton must be at least 50 ms to operate the
pushbutton. This allows the user-programmable pushbuttons to properly operate during power cycling events
NOTE
and various system disturbances that can cause transient assertion of the operating signals.
The local and remote operation of each user-programmable pushbutton can be inhibited through the PUSHBTN 1 LOCAL
and PUSHBTN 1 REMOTE settings, respectively. If local locking is applied, the pushbutton ignores set and reset commands
executed through the front panel pushbuttons. If remote locking is applied, the pushbutton ignores set and reset
commands executed through FlexLogic operands.
The locking functions are not applied to the autoreset feature. In this case, the inhibit function can be used in SBO control
operations to prevent the pushbutton function from being activated and ensuring “one-at-a-time” select operation.
5 The locking functions can also be used to prevent the accidental pressing of the front panel pushbuttons. The separate
inhibit of the local and remote operation simplifies the implementation of local/remote control supervision.
Pushbutton states can be logged by the event recorder and displayed as target messages. In latched mode, user-defined
messages can also be associated with each pushbutton and displayed when the pushbutton is on or changing to off.
PUSHBUTTON 1 FUNCTION — This setting selects the characteristic of the pushbutton. If set to “Disabled,” the pushbutton is
not active and the corresponding FlexLogic operands (both “On” and “Off”) are de-asserted. If set to “Self-Reset,” the
control logic is activated by the pulse (longer than 100 ms) issued when the pushbutton is being physically pressed or
virtually pressed via a FlexLogic operand assigned to the PUSHBTN 1 SET setting.
When in “Self-Reset” mode and activated locally, the pushbutton control logic asserts the “On” corresponding FlexLogic
operand as long as the pushbutton is being physically pressed, and after being released the deactivation of the operand is
delayed by the drop out timer. The “Off” operand is asserted when the pushbutton element is deactivated. If the
pushbutton is activated remotely, the control logic of the pushbutton asserts the corresponding “On” FlexLogic operand
only for the time period specified by the PUSHBTN 1 DROP-OUT TIME setting.
If set to “Latched,” the control logic alternates the state of the corresponding FlexLogic operand between “On” and “Off” on
each button press or by virtually activating the pushbutton (assigning set and reset operands). When in the “Latched”
mode, the states of the FlexLogic operands are stored in a non-volatile memory. If power supply is lost, the correct state of
the pushbutton is retained upon subsequent power up of the relay.
PUSHBTN 1 ID TEXT — This setting specifies the top 20-character line of the user-programmable message and is intended to
provide ID information of the pushbutton. See the User-definable Displays section for instructions on how to enter
alphanumeric characters from the keypad.
PUSHBTN 1 ON TEXT — This setting specifies the bottom 20-character line of the user-programmable message and is
displayed when the pushbutton is in the “on” position. See the User-definable Displays section for instructions on entering
alphanumeric characters from the keypad.
PUSHBTN 1 OFF TEXT — This setting specifies the bottom 20-character line of the user-programmable message and is
displayed when the pushbutton is activated from the on to the off position and the PUSHBUTTON 1 FUNCTION is “Latched.”
This message is not displayed when the PUSHBUTTON 1 FUNCTION is “Self-reset” as the pushbutton operand status is
implied to be “Off” upon its release. The length of the “Off” message is configured with the PRODUCT SETUP DISPLAY
PROPERTIES FLASH MESSAGE TIME setting.
PUSHBTN 1 HOLD — This setting specifies the time required for a pushbutton to be pressed before it is deemed active. This
timer is reset upon release of the pushbutton. Note that any pushbutton operation requires the pushbutton to be pressed a
minimum of 50 ms. This minimum time is required prior to activating the pushbutton hold timer.
PUSHBTN 1 SET — This setting assigns the FlexLogic operand serving to operate the pushbutton element and to assert
PUSHBUTTON 1 ON operand. The duration of the incoming set signal must be at least 100 ms.
PUSHBTN 1 RESET — This setting assigns the FlexLogic operand serving to reset pushbutton element and to assert
PUSHBUTTON 1 OFF operand. This setting is applicable only if pushbutton is in latched mode. The duration of the incoming
reset signal must be at least 50 ms.
PUSHBTN 1 AUTORST — This setting enables the user-programmable pushbutton autoreset feature. This setting is applicable
only if the pushbutton is in the “Latched” mode.
PUSHBTN 1 AUTORST DELAY — This setting specifies the time delay for automatic reset of the pushbutton when in the
latched mode.
PUSHBTN 1 REMOTE — This setting assigns the FlexLogic operand serving to inhibit pushbutton operation from the operand
assigned to the PUSHBTN 1 SET or PUSHBTN 1 RESET settings.
PUSHBTN 1 LOCAL — This setting assigns the FlexLogic operand serving to inhibit pushbutton operation from the front panel
pushbuttons. This locking functionality is not applicable to pushbutton autoreset.
PUSHBTN 1 DROP-OUT TIME — This setting applies only to “Self-Reset” mode and specifies the duration of the pushbutton
active status after the pushbutton has been released. When activated remotely, this setting specifies the entire activation
time of the pushbutton status; the length of time the operand remains on has no effect on the pulse duration. This setting
is required to set the duration of the pushbutton operating pulse.
PUSHBTN 1 LED CTL — This setting assigns the FlexLogic operand serving to drive pushbutton LED. If this setting is “Off,” then
LED operation is directly linked to the PUSHBUTTON 1 ON operand.
PUSHBTN 1 MESSAGE — If pushbutton message is set to “High Priority,” the message programmed in the PUSHBTN 1 ID and
PUSHBTN 1 ON TEXT settings are displayed undisturbed as long as PUSHBUTTON 1 ON operand is asserted. The high priority
5
option is not applicable to the PUSHBTN 1 OFF TEXT setting.
This message can be temporary removed if any front panel keypad button is pressed. However, 10 seconds of keypad
inactivity restores the message if the PUSHBUTTON 1 ON operand is still active.
If the PUSHBTN 1 MESSAGE is set to “Normal,” the message programmed in the PUSHBTN 1 ID and PUSHBTN 1 ON TEXT settings
are displayed as long as PUSHBUTTON 1 ON operand is asserted, but not longer than time period specified by FLASH MESSAGE
TIME setting. After the flash time is expired, the default message or other active target message is displayed. The
instantaneous reset of the flash message is executed if any relay front panel button is pressed or any new target or
message becomes active.
The PUSHBTN 1 OFF TEXT setting is linked to PUSHBUTTON 1 OFF operand and displays in conjunction with PUSHBTN 1 ID only if
pushbutton element is in the “Latched” mode. The PUSHBTN 1 OFF TEXT message displays as “Normal” if the PUSHBTN 1
MESSAGE setting is “High Priority” or “Normal.”
PUSHBUTTON 1 EVENTS — If this setting is enabled, each pushbutton state change is logged as an event into the event
recorder.

This feature provides a mechanism where any of 256 selected FlexLogic operand states can be used for efficient
monitoring. The feature allows user-customized access to the FlexLogic operand states in the relay. The state bits are
packed so that 16 states are readable in a single Modbus register. The state bits can be configured so that all states of
interest are available in a minimum number of Modbus registers.
The state bits can be read out in the “Flex States” register array beginning at Modbus address 0900h. Sixteen states are
packed into each register, with the lowest-numbered state in the lowest-order bit. Sixteen registers accommodate the 256
state bits.

This menu provides a mechanism for manually creating up to 16 user-defined information displays in a convenient
viewing sequence in the USER DISPLAY menu (between the TARGETS and ACTUAL VALUES top-level menus). The sub-menus
5 facilitate text entry and Modbus register data pointer options for defining the user display content.
Once programmed, the user-definable displays can be viewed in two ways.
• Keypad — Use the MENU key to select the USER DISPLAY menu item to access the first user-definable display (note that
only the programmed screens are displayed). The screens can be scrolled using the up and down arrow keys. The
display disappears after the default message time-out period specified by the PRODUCT SETUP DISPLAY PROPERTIES
DEFAULT MESSAGE TIMEOUT setting.
• User-programmable control input — The user-definable displays also respond to the INVOKE AND SCROLL setting. Any
FlexLogic operand (in particular, the user-programmable pushbutton operands), can be used to navigate the
programmed displays.
On the rising edge of the configured operand (such as when the pushbutton is pressed), the displays are invoked by
showing the last user-definable display shown during the previous activity. From this moment onward, the operand
acts exactly as the down key and allows scrolling through the configured displays. The last display wraps up to the
first one. The INVOKE AND SCROLL input and the down arrow key operate concurrently.
When the default timer expires (set by the DEFAULT MESSAGE TIMEOUT setting), the relay starts to cycle through the user
displays. The next activity of the INVOKE AND SCROLL input stops the cycling at the currently displayed user display, not
at the first user-defined display. The INVOKE AND SCROLL pulses must last for at least 250 ms to take effect.
Any existing system display can be automatically copied into an available user display by selecting the existing display and
pressing the ENTER key. The display then prompts with ADD TO USER DISPLAY LIST? After selecting “Yes,” a message
indicates that the selected display has been added to the user display list. When this type of entry occurs, the sub-menus
are automatically configured with the proper content—this content can be edited subsequently.
This menu is used to enter user-defined text and user-selected Modbus-registered data fields into the particular user
display. Each user display consists of two 20-character lines (top and bottom). The tilde (~) character is used to mark the
start of a data field – the length of the data field needs to be accounted for. Up to five separate data fields can be entered
in a user display – the nth tilde (~) refers to the nth item.
A user display can be entered from the faceplate keypad or the EnerVista interface (preferred for convenience). The
following procedure shows how to enter text characters in the top and bottom lines from the faceplate keypad:
1. Select the line to be edited.
2. Press the decimal key to enter text edit mode.
3. Use either VALUE key to scroll through the characters. A space is selected like a character.
4. Press the decimal key to advance the cursor to the next position.
5. Repeat step 3 and continue entering characters until the desired text is displayed.
6. The HELP key can be pressed at any time for context sensitive help information.
7. Press the ENTER key to store the new settings.
To enter a numerical value for any of the five items (the decimal form of the selected Modbus address) from the faceplate
keypad, use the number keypad. Use the value of “0” for any items not being used. Use the HELP key at any selected
system display (setting, actual value, or command) which has a Modbus address, to view the hexadecimal form of the
Modbus address, then manually convert it to decimal form before entering it (EnerVista usage conveniently facilitates this 5
conversion).
Use the MENU key to go to the user displays menu to view the user-defined content. The current user displays show in
sequence, changing every four seconds. While viewing a user display, press the ENTER key and then select the ‘Yes” option
to remove the display from the user display list. Use the MENU key again to exit the user displays menu.
An example of user display setup and result is shown as follows.
USER DISPLAY 1 DISP 1 TOP LINE: Shows user-defined text with first tilde marker
Current X ~ A
DISP 1 BOTTOM LINE: Shows user-defined text with second tilde marker
Current Y ~ A
If the parameters for the top line and the bottom line items have the same units, then the unit is displayed on the bottom
line only. The units are only displayed on both lines if the units specified both the top and bottom line items are different.

5 MESSAGES ALARM CH2
This option is available when an Inter-Relay Communications card is specified at the time of ordering (see
the Order Code tables). With the option, direct inputs/outputs display by default. When you enable the
teleprotection feature, direct I/O is not visible.
Direct inputs and outputs exchange status information (inputs and outputs) between UR-series relays connected directly
via type 7 digital communications cards. The mechanism is very similar to IEC 61850 GOOSE, except that communications
takes place over a non-switchable isolated network and is optimized for speed. On type 7 cards that support two channels,
direct output messages are sent from both channels simultaneously. This effectively sends direct output messages both
ways around a ring configuration. On type 7 cards that support one channel, direct output messages are sent only in one
direction. Messages are resent (forwarded) when it is determined that the message did not originate at the receiver.
Teleprotection inputs/outputs and direct inputs/outputs are mutually exclusive. As such, they cannot be used
simultaneously. Once teleprotection inputs and outputs are enabled, direct inputs and outputs are blocked,
NOTE
and vice versa.
Direct output message timing is similar to GOOSE message timing. Integrity messages (with no state changes) are sent at
least every 1000 ms. Messages with state changes are sent within the main pass scanning the inputs and asserting the
outputs unless the communication channel bandwidth has been exceeded. Two self-tests are performed and signaled by
the following FlexLogic operands:
• DIRECT RING BREAK (direct input/output ring break). This FlexLogic operand indicates that direct output messages sent
from a UR-series relay are not being received back by the relay.
• DIRECT DEVICE 1 OFF to DIRECT DEVICE 16 OFF (direct device offline). These FlexLogic operands indicate that direct output
messages from at least one direct device are not being received.
Direct input and output settings are similar to remote input and output settings. The equivalent of the remote device name
strings for direct inputs and outputs is the DIRECT OUTPUT DEVICE ID setting, which identifies the relay in all direct output
messages. All UR-series IEDs in a ring need to have unique numbers assigned. The IED ID is used to identify the sender of
the direct input and output message.
If the direct input and output scheme is configured to operate in a ring (DIRECT I/O CH1 RING CONFIGURATION or DIRECT I/O
CH2 RING CONFIGURATION is “Yes”), all direct output messages are received back. If not, the direct input/output ring break
self-test is triggered. The self-test error is signaled by the DIRECT RING BREAK FlexLogic operand.
Select the DIRECT I/O DATA RATE to match the data capabilities of the communications channel. All IEDs communicating
over direct inputs and outputs must be set to the same data rate. UR-series IEDs equipped with dual-channel
communications cards apply the same data rate to both channels. Delivery time for direct input and output messages is
approximately 0.2 of a power system cycle at 128 kbps and 0.4 of a power system cycle at 64 kbps, per each "bridge."

NOTE
5 The DIRECT I/O CHANNEL CROSSOVER setting applies to C30s with dual-channel communication cards and allows crossing
over messages from channel 1 to channel 2. This places all UR-series IEDs into one direct input and output network
regardless of the physical media of the two communication channels.
The following application examples illustrate the basic concepts for direct input and output configuration. See the Inputs

Message delivery time is approximately 0.2 of power system cycle (at 128 kbps) times number of ‘bridges’ between the
origin and destination. Dual-ring configuration effectively reduces the maximum ‘communications distance’ by a factor of
two.
In this configuration the following delivery times are expected (at 128 kbps) if both rings are healthy:
IED 1 to IED 2: 0.2 of power system cycle
IED 1 to IED 3: 0.4 of power system cycle
IED 1 to IED 4: 0.2 of power system cycle
IED 2 to IED 3: 0.2 of power system cycle
IED 2 to IED 4: 0.4 of power system cycle
IED 3 to IED 4: 0.2 of power system cycle
If one ring is broken (say TX2-RX2) the delivery times are as follows:
IED 1 to IED 2: 0.2 of power system cycle
IED 1 to IED 3: 0.4 of power system cycle
IED 1 to IED 4: 0.6 of power system cycle
IED 2 to IED 3: 0.2 of power system cycle
IED 2 to IED 4: 0.4 of power system cycle
IED 3 to IED 4: 0.2 of power system cycle
A coordinating timer for this bus protection scheme could be selected to cover the worst case scenario (0.4 of a power
system cycle). Upon detecting a broken ring, the coordination time is adaptively increased to 0.6 of a power system cycle.
The complete application requires addressing a number of issues, such as failure of both the communications rings, failure
or out-of-service conditions of one of the relays, and so on. Self-monitoring flags of the direct inputs and outputs feature
primarily are used to address these concerns.

The C30 checks integrity of the incoming direct input and output messages using a 32-bit CRC. The CRC alarm function is
available for monitoring the communication medium noise by tracking the rate of messages failing the CRC check. The
monitoring function counts all incoming messages, including messages that failed the CRC check. A separate counter
adds up messages that failed the CRC check. When the failed CRC counter reaches the user-defined level specified by the
CRC ALARM CH1 THRESHOLD setting within the user-defined message count CRC ALARM 1 CH1 COUNT, the DIR IO CH1 CRC ALARM
FlexLogic operand is set.
When the total message counter reaches the user-defined maximum specified by the CRC ALARM CH1 MESSAGE COUNT
setting, both the counters reset and the monitoring process is restarted.
Configure the operand to drive an output contact, user-programmable LED, or selected communication-based output.
Latching and acknowledging conditions—if required—are programmed accordingly.
The CRC alarm function is available on a per-channel basis. The total number of direct input and output messages that
failed the CRC check is available as the ACTUAL VALUES STATUS DIRECT INPUTS CRC FAIL COUNT CH1 actual value.
5 • Message count and length of the monitoring window — To monitor communications integrity, the relay sends 1
message per second (at 64 kbps) or 2 messages per second (128 kbps) even if there is no change in the direct outputs.
For example, setting the CRC ALARM CH1 MESSAGE COUNT to “10000,” corresponds a time window of about 160 minutes
at 64 kbps and 80 minutes at 128 kbps. If the messages are sent faster as a result of direct outputs activity, the
monitoring time interval shortens. Take this into account when determining the CRC ALARM CH1 MESSAGE COUNT
setting. For example, if the requirement is a maximum monitoring time interval of 10 minutes at 64 kbps, then the CRC
ALARM CH1 MESSAGE COUNT is set to 10 × 60 × 1 = 600.
• Correlation of failed CRC and bit error rate (BER) — The CRC check can fail if one or more bits in a packet are
corrupted. Therefore, an exact correlation between the CRC fail rate and the BER is not possible. Under certain
assumptions an approximation can be made as follows. A direct input and output packet containing 20 bytes results
in 160 bits of data being sent and therefore, a transmission of 63 packets is equivalent to 10,000 bits. A BER of 10–4
implies 1 bit error for every 10000 bits sent or received. Assuming the best case of only 1 bit error in a failed packet,
having 1 failed packet for every 63 received is about equal to a BER of 10–4.
The C30 checks integrity of the direct input and output communication ring by counting unreturned messages. In the ring
configuration, all messages originating at a given device should return within a pre-defined period of time. The unreturned
messages alarm function is available for monitoring the integrity of the communication ring by tracking the rate of
unreturned messages. This function counts all the outgoing messages and a separate counter adds the messages have
failed to return. When the unreturned messages counter reaches the user-definable level specified by the UNRET MSGS
ALARM CH1 THRESHOLD setting and within the user-defined message count UNRET MSGS ALARM CH1 COUNT, the DIR IO CH1
UNRET ALM FlexLogic operand is set.
When the total message counter reaches the user-defined maximum specified by the UNRET MSGS ALARM CH1 MESSAGE
COUNT setting, both the counters reset and the monitoring process is restarted.
Configure the operand to drive an output contact, user-programmable LED, or selected communication-based output.
Latching and acknowledging conditions, if required, are programmed accordingly.
The unreturned messages alarm function is available on a per-channel basis and is active only in the ring configuration.
The total number of unreturned input and output messages is available as the ACTUAL VALUES STATUS DIRECT INPUTS
UNRETURNED MSG COUNT CH1 actual value.
5.3.16 Teleprotection
SETTINGS PRODUCT SETUP TELEPROTECTION
TELEPROTECTION TELEPROTECTION Range: Disabled, Enabled
FUNCTION: Disabled
This option is available when an Inter-Relay Communications card is specified at the time of ordering (see
the Order Code tables). With the option, direct inputs/outputs display by default. When you enable the
teleprotection feature, direct I/O is not visible.
Digital teleprotection transfers protection commands between two or three relays in a secure, fast, dependable, and
deterministic way. Possible applications are permissive or blocking pilot schemes and direct transfer trip (DTT).
Teleprotection can be applied over any analog or digital channels and any communications media, such as direct fiber,
copper wires, optical networks, or microwave radio links. A mixture of communication media is possible.
Once teleprotection is enabled and the teleprotection input/outputs are configured, data packets are transmitted
continuously every 1/4 cycle (3/8 cycle if using C37.94 modules) from peer-to-peer. Security of communication channel
data is achieved by using CRC-32 on the data packet.
Teleprotection inputs/outputs and direct inputs/outputs are mutually exclusive. As such, they cannot be used
simultaneously. Once teleprotection inputs and outputs are enabled, direct inputs and outputs are blocked,
NOTE
and vice versa.
NUMBER OF TERMINALS — Specifies whether the teleprotection system operates between two peers or three peers.
NUMBER OF CHANNELS — Specifies how many channels are used. If the NUMBER OF TERMINALS is “3” (three-terminal system),
set the NUMBER OF CHANNELS to “2.” For a two-terminal system, the NUMBER OF CHANNELS can set to “1” or “2” (redundant
channels).
LOCAL RELAY ID NUMBER , TERMINAL 1 RELAY ID NUMBER , and TERMINAL 2 RELAY ID NUMBER — In installations that use
multiplexers or modems, it is desirable to ensure that the data used by the relays protecting a given line is from the correct
relays. The teleprotection function performs this check by reading the message ID sent by transmitting relays and
comparing it to the programmed ID in the receiving relay. This check is also used to block inputs if inadvertently set to
loopback mode or data is being received from a wrong relay by checking the ID on a received channel. If an incorrect ID is
found on a channel during normal operation, the TELEPROT CH1 ID FAIL or TELEPROT CH2 ID FAIL FlexLogic operand is set, driving the
event with the same name and blocking the teleprotection inputs. For commissioning purposes, the result of channel
identification is also shown in the STATUS CHANNEL TESTS VALIDITY OF CHANNEL CONFIGURATION actual value. The
default value of “0” for the LOCAL RELAY ID NUMBER indicates that relay ID is not to be checked. On two- terminals two-
channel systems, the same LOCAL RELAY ID NUMBER is transmitted over both channels; as such, only the TERMINAL 1 ID
NUMBER has to be programmed on the receiving end.

5.4 Remote resources
5.4.1 Remote resources configuration
When the C30 is ordered with a process card module as a part of HardFiber system, an additional Remote Resources
menu tree is available in the EnerVista software to allow configuration of the HardFiber system.
Figure 5-44: Remote Resources configuration menu
The remote resources settings configure a C30 with a process bus module to work with HardFiber Bricks. Remote
resources configuration is only available through the EnerVista software, and is not available through the C30 front panel.
A Brick provides eight AC measurements, along with contact inputs, DC analog inputs, and contact outputs, to be the
remote interface to field equipment such as circuit breakers and transformers. The C30 with a process bus module has
access to all of the capabilities of up to eight Bricks. Remote resources settings configure the point-to-point connection
between specific fiber optic ports on the C30 process card and specific Brick. The relay is then configured to measure
specific currents, voltages and contact inputs from those Bricks, and to control specific outputs.
The configuration process for remote resources is straightforward and consists of the following steps.
• Configure the field units. This establishes the point-to-point connection between a specific port on the relay process
bus module, and a specific digital core on a specific Brick. This is a necessary first step in configuring a process bus
relay.
• Configure the AC banks. This sets the primary and secondary quantities and connections for currents and voltages. AC
bank configuration also provides a provision for redundant measurements for currents and voltages, a powerful
reliability improvement possible with process bus.
• Configure signal sources. This functionality of the C30 has not changed other than the requirement to use currents
and voltages established by AC bank configuration under the remote resources menu.
• Configure field contact inputs, field contact outputs, RTDs, and transducers as required for the application's
functionality. These inputs and outputs are the physical interface to circuit breakers, transformers, and other
equipment. They replace the traditional contact inputs and outputs located at the relay to virtually eliminate copper
wiring.
• Configure shared inputs and outputs as required for the application's functionality. Shared inputs and outputs are
distinct binary channels that provide high-speed protection quality signaling between relays through a Brick.
For additional information on how to configure a relay with a process bus module, see the HardFiber Process Bus System
Instruction Manual.

program the settings is covered here. These features are provided for two or more breakers; a user can use only those
portions of the design relevant to a single breaker, which must be breaker 1.
The number of breaker control elements depends on the number of CT/VT modules specified with the C30. The following
settings are available for each breaker control element.
BREAKER 1 FUNCTION — This setting enables and disables the operation of the breaker control feature.
BREAKER1 PUSH BUTTON CONTROL — Set to “Enable” to allow faceplate pushbutton operations.
BREAKER 1 NAME — Assign a user-defined name (up to six characters) to the breaker. This name is used in flash messages
related to breaker 1.
BREAKER 1 MODE — Selects “3-Pole” mode, where all breaker poles are operated simultaneously, or “1-Pole” mode where all
breaker poles are operated either independently or simultaneously.
BREAKER 1 OPEN — Selects an operand that creates a programmable signal to operate an output relay to open breaker 1.
BREAKER 1 BLK OPEN — Selects an operand that prevents opening of the breaker. This setting can be used for select-before-
operate functionality or to block operation from a panel switch or from SCADA.
BREAKER 1 CLOSE — Selects an operand that creates a programmable signal to operate an output relay to close breaker 1.
BREAKER 1 BLK CLOSE — Selects an operand that prevents closing of the breaker. This setting can be used for select-before-
operate functionality or to block operation from a panel switch or from SCADA.
BREAKER 1 ΦA/3P CLOSED — Selects an operand, usually a contact input connected to a breaker auxiliary position tracking
mechanism. This input is a normally-open 52/a status input to create a logic 1 when the breaker is closed. If the BREAKER 1
MODE setting is selected as “3-Pole,” this setting selects a single input as the operand used to track the breaker open or
closed position. If the mode is selected as “1-Pole,” the input mentioned is used to track phase A and the BREAKER 1 ΦB and
BREAKER 1 ΦC settings select operands to track phases B and C, respectively.
BREAKER 1 ΦA/3P OPND — Selects an operand, usually a contact input, that is a normally-closed 52/b status input to create
a logic 1 when the breaker is open. If a separate 52/b contact input is not available, then the inverted BREAKER 1 CLOSED status
signal can be used.
BREAKER 1 ΦB CLOSED — If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the breaker phase B closed position as outlined for phase A.
BREAKER 1 ΦB OPENED — If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the breaker phase B opened position as outlined for phase A.
BREAKER 1 ΦC CLOSED — If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the breaker phase C closed position as outlined for phase A.
BREAKER 1 ΦC OPENED — If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the breaker phase C opened position as outlined for phase A.
BREAKER 1 Toperate — This setting specifies the required interval to overcome transient disagreement between the 52/a
and 52/b auxiliary contacts during breaker operation. If transient disagreement still exists after this time has expired, the
BREAKER 1 BAD STATUS FlexLogic operand is asserted from alarm or blocking purposes.
BREAKER 1 EXT ALARM — This setting selects an operand, usually an external contact input, connected to a breaker alarm
reporting contact.
BREAKER 1 ALARM DELAY — This setting specifies the delay interval during which a disagreement of status among the three-
pole position tracking operands does not declare a pole disagreement. This allows for non-simultaneous operation of the
poles.
MANUAL CLOSE RECAL1 TIME — This setting specifies the interval required to maintain setting changes in effect after an
operator has initiated a manual close command to operate a circuit breaker.
BREAKER 1 OUT OF SV — Selects an operand indicating that breaker 1 is out-of-service.

SETTINGS SYSTEM SETUP SWITCHES SWITCH 1(8)
SWITCH 1 SWITCH 1 Range: Disabled, Enabled
FUNCTION: Disabled
The disconnect switch element contains the auxiliary logic for status and serves as the interface for opening and closing of
disconnect switches from SCADA or through the front panel interface. The disconnect switch element can be used to
create interlocking functionality. For greater security in determination of the switch pole position, both the 89/a and 89/b
auxiliary contacts are used with reporting of the discrepancy between them. The number of available disconnect switches
depends on the number of the CT/VT modules ordered with the C30.
SWITCH 1 FUNCTION — This setting enables and disables operation of the disconnect switch element.
SWITCH 1 NAME — Assign a user-defined name (up to six characters) to the disconnect switch. This name is used in flash
messages related to disconnect switch 1.
SWITCH 1 MODE — This setting selects “3-Pole” mode, where disconnect switch poles have a single common auxiliary
switch, or “1-Pole” mode where each disconnect switch pole has its own auxiliary switch.
SWITCH 1 OPEN — This setting selects an operand that creates a programmable signal to operate a contact output to open
disconnect switch 1.
SWITCH 1 BLK OPEN — This setting selects an operand that prevents opening of the disconnect switch. This setting can be
used for select-before-operate functionality or to block operation from a panel switch or from SCADA.
SWITCH 1 CLOSE — This setting selects an operand that creates a programmable signal to operate a contact output to close
disconnect switch 1.
SWITCH 1 BLK CLOSE — This setting selects an operand that prevents closing of the disconnect switch. This setting can be
used for select-before-operate functionality or to block operation from a panel switch or from SCADA.
SWTCH 1 ΦA/3P CLSD — This setting selects an operand, usually a contact input connected to a disconnect switch auxiliary
position tracking mechanism. This input is a normally-open 89/a status input to create a logic 1 when the disconnect
switch is closed. If the SWITCH 1 MODE setting is selected as “3-Pole,” this setting selects a single input as the operand used
to track the disconnect switch open or closed position. If the mode is selected as “1-Pole,” the input mentioned is used to
track phase A and the SWITCH 1 ΦB and SWITCH 1 ΦC settings select operands to track phases B and C, respectively.
SWTCH 1 ΦA/3P OPND — This setting selects an operand, usually a contact input, that is a normally-closed 89/b status input
to create a logic 1 when the disconnect switch is open. If a separate 89/b contact input is not available, then an inverted
89/a status signal can be used.
SWITCH 1 ΦB CLOSED — If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the disconnect switch phase B closed position as outlined for phase A.
SWITCH 1 ΦB OPENED — If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-

SWITCH 1 ΦC CLOSED — If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the disconnect switch phase C closed position as outlined for phase A.
SWITCH 1 ΦC OPENED — If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
pole, this input is used to track the disconnect switch phase C opened position as outlined for phase A.
SWITCH 1 Toperate — This setting specifies the required interval to overcome transient disagreement between the 89/a and
89/b auxiliary contacts during disconnect switch operation. If transient disagreement still exists after this time has expired,
the SWITCH 1 BAD STATUS FlexLogic operand is asserted from alarm or blocking purposes.
SWITCH 1 ALARM DELAY — This setting specifies the delay interval during which a disagreement of status among the three-
5
pole position tracking operands do not declare a pole disagreement. This allows for non-simultaneous operation of the
poles.

The switch element has direct hard-coded connections to the IEC 61850 model as shown in the logic diagram. This allows
remote open/close operation of each switch, using either CSWI or XSWI IEC 61850 logical nodes. IEC 61850 select-before-
operate functionality, local/remote switch functionality, along with blocking open/close commands are provided. Note that
the dwell time for the IEC 61850 trip and close commands shown is one protection pass only. To maintain close/open
command for a certain time, do so either on the contact outputs using the "Seal-in" setting or in FlexLogic.
5.6 FlexLogic
5.6.1 FlexLogic operands
For flexibility, the arrangement of internal digital logic combines fixed and user-programmed parameters. Logic upon
which individual features are designed is fixed, and all other logic, from contact input signals through elements or
combinations of elements to contact outputs, is variable. The user has complete control of all variable logic through
FlexLogic. In general, the system receives analog and digital inputs that it uses to produce analog and digital outputs. The
figure shows major subsystems of a generic UR-series relay involved in this process.

The states of all digital signals used in the C30 are represented by flags (or FlexLogic operands, which are described later in
this section). A digital “1” is represented by a set flag. Any external contact change-of-state can be used to block an
element from operating, as an input to a control feature in a FlexLogic equation, or to operate a contact output. The state
of the contact input can be displayed locally or viewed remotely via the communications facilities provided. If a simple
scheme where a contact input is used to block an element is wanted, this selection is made when programming the
element. This capability also applies to the other features that set flags: elements, virtual inputs, remote inputs, schemes,
and human operators.
If more complex logic than shown in the figure is required, it is implemented via FlexLogic. For example, to have the closed
state of contact input H7a and the operated state of the phase undervoltage element block the operation of the phase
time overcurrent element, the two control input states are programmed in a FlexLogic equation. This equation ANDs the
two control inputs to produce a virtual output that is then selected when programming the phase time overcurrent to be
used as a blocking input. Virtual outputs can only be created by FlexLogic equations.
Traditionally, protective relay logic has been relatively limited. Any unusual applications involving interlocks, blocking, or
supervisory functions had to be hard-wired using contact inputs and outputs. FlexLogic minimizes the requirement for
auxiliary components and wiring while making more complex schemes possible.
The logic that determines the interaction of inputs, elements, schemes, and outputs is field-programmable through the use
of logic equations that are sequentially processed. The use of virtual inputs and outputs in addition to hardware is
available internally and on the communication ports for other relays to use (distributed FlexLogic).
FlexLogic allows users to customize the relay through a series of equations that consist of operators and operands. The
operands are the states of inputs, elements, schemes, and outputs. The operators are logic gates, timers, and latches (with
set and reset inputs). A system of sequential operations allows any combination of operands to be assigned as inputs to
specified operators to create an output. The final output of an equation is a numbered register called a virtual output.
Virtual outputs can be used as an input operand in any equation, including the equation that generates the output, as a
seal-in or other type of feedback.
A FlexLogic equation consists of parameters that are either operands or operators. Operands have a logic state of 1 or 0.
Operators provide a defined function, such as an AND gate or a Timer. Each equation defines the combinations of
parameters to be used to set a Virtual Output flag. Evaluation of an equation results in either a 1 (=ON, or flag set) or 0
(=OFF, or flag not set). Each equation is evaluated at least four times every power system cycle.
5 Some types of operands are present in the relay in multiple instances, for example contact and remote inputs. These types
of operands are grouped together (for presentation purposes only) on the faceplate display. The table lists characteristics
of the different types of operands.

Some operands can be re-named. These are the names of the breakers in the breaker control feature, the ID (identification)
of contact inputs, the ID of virtual inputs, and the ID of virtual outputs. If the user changes the default name or ID of any of
these operands, the assigned name appears in the relay list of operands. The default names are shown in the FlexLogic
operands table.
The characteristics of the logic gates are tabulated in the following table, and the operators available in FlexLogic are
listed in the FlexLogic operators table.
FlexLogic provides built-in latches that by definition have a memory action, remaining in the set state after the
set input has been asserted. These built-in latches are reset dominant, meaning that if logical "1" is applied to
NOTE
both set and reset entries simultaneously, then the output of the latch is logical "0." However, they are volatile,
meaning that they reset upon removal of control power.
When making changes to FlexLogic entries in the settings, all FlexLogic equations are re-compiled whenever
any new FlexLogic entry value is entered, and as a result of the re-compile all latches are reset automatically.
1. Inspect the example logic diagram to determine if the required logic can be implemented with the FlexLogic
operators. If this is not possible, the logic must be altered until this condition is satisfied. Once done, count the inputs
to each gate to verify that the number of inputs does not exceed the FlexLogic limits, which is unlikely but possible. If
the number of inputs is too high, subdivide the inputs into multiple gates to produce an equivalent. For example, if 25
inputs to an AND gate are required, connect Inputs 1 through 16 to AND(16), 17 through 25 to AND(9), and the outputs
from these two gates to AND(2).
Inspect each operator between the initial operands and final virtual outputs to determine if the output from the
operator is used as an input to more than one following operator. If so, the operator output must be assigned as a
virtual output.
For the example shown, the output of the AND gate is used as an input to both OR#1 and Timer 1, and must therefore
be made a virtual output and assigned the next available number (that is, Virtual Output 3). The final output must also
be assigned to a virtual output as virtual output 4, which is programmed in the contact output section to operate relay
H1 (that is, contact output H1).
Therefore, the required logic can be implemented with two FlexLogic equations with outputs of virtual output 3 and
virtual output 4, shown as follows.

2. Prepare a logic diagram for the equation to produce virtual output 3, as this output is used as an operand in the virtual
output 4 equation (create the equation for every output that is used as an operand first, so that when these operands
are required they already have been evaluated and assigned to a specific virtual output). The logic for virtual output 3
is shown as follows with the final output assigned.

4. Program the FlexLogic equation for virtual output 3 by translating the logic into available FlexLogic parameters. The
equation is formed one parameter at a time until the required logic is complete. It is generally easier to start at the
output end of the equation and work back towards the input, as shown in the following steps. It is also recommended
to list operator inputs from bottom to top. For demonstration, the final outputs are arbitrarily identified as parameter
99, and each preceding parameter decremented by one in turn. Until accustomed to using FlexLogic, it is suggested
that a worksheet with a series of cells marked with the arbitrary parameter numbers be prepared shown as follows.

6. Repeating the process described for virtual output 3, select the FlexLogic parameters for Virtual Output 4.
– 99: The final output of the equation is virtual output 4, which is parameter “= Virt Op 4".
– 98: The operator preceding the output is timer 2, which is operand “TIMER 2". Note that the settings required for
the timer are established in the timer programming section.
– 97: The operator preceding timer 2 is OR #2, a 3-input OR, which is parameter “OR(3)”.
– 96: The lowest input to OR #2 is operand “Cont Ip H1c On”.
– 95: The center input to OR #2 is operand “TIMER 1".
– 94: The input to timer 1 is operand “Virt Op 3 On".
– 93: The upper input to OR #2 is operand “LATCH (S,R)”.
– 92: There are two inputs to a latch, and the input immediately preceding the latch reset is OR #1, a 4-input OR,
which is parameter “OR(4)”.
– 91: The lowest input to OR #1 is operand “Virt Op 3 On".
5 – 90: The input just above the lowest input to OR #1 is operand “XOR(2)”.
– 89: The lower input to the XOR is operand “DIG ELEM 1 PKP”.
– 88: The upper input to the XOR is operand “Virt Ip 1 On".
– 87: The input just below the upper input to OR #1 is operand “Virt Op 2 On".
– 86: The upper input to OR #1 is operand “Virt Op 1 On".
– 85: The last parameter is used to set the latch, and is operand “Virt Op 4 On".
The equation for virtual output 4 is:
[85] Virt Op 4 On
[86] Virt Op 1 On
[87] Virt Op 2 On
[88] Virt Ip 1 On
[89] DIG ELEM 1 PKP
[90] XOR(2)

[94] Virt Op 3 On
[95] TIMER 1
[96] Cont Ip H1c On
[97] OR(3)
[98] TIMER 2
[99] = Virt Op 4
Now check that the selection of parameters produce the required logic by converting the set of parameters into a
logic diagram. The result is shown in the figure, which is compared to the logic for virtual output 4 diagram as a check.

7. Now write the complete FlexLogic expression required to implement the logic, making an effort to assemble the
5
equation in an order where Virtual Outputs that are used as inputs to operators are created before needed. In cases
where a lot of processing is required to perform logic, this can be difficult to achieve, but in most cases does not cause
problems as all logic is calculated at least four times per power frequency cycle. The possibility of a problem caused by
sequential processing emphasizes the necessity to test the performance of FlexLogic before it is placed in service.
In the following equation, virtual output 3 is used as an input to both latch 1 and timer 1 as arranged in the following
order:
DIG ELEM 2 OP
Cont Ip H1c On
NOT
AND(2)
= Virt Op 3
Virt Op 4 On
Virt Op 1 On
Virt Op 2 On
Virt Ip 1 On
DIG ELEM 1 PKP
XOR(2)
Virt Op 3 On
OR(4)
LATCH (S,R)
Virt Op 3 On
TIMER 1
Cont Ip H1c On
OR(3)
TIMER 2
= Virt Op 4
END
In this expression, the virtual output 4 input to the four-input OR is listed before it is created. This is typical of a form of
feedback, in this case, used to create a seal-in effect with the latch, and is correct.
8. Always test the logic after it is loaded into the relay, in the same way as has been used in the past. Testing can be
simplified by placing an "END" operator within the overall set of FlexLogic equations. The equations are evaluated up
to the first "END" operator.
The "On" and "Off" operands can be placed in an equation to establish a known set of conditions for test purposes, and
the "INSERT" and "DELETE" commands can be used to modify equations.
There are 512 FlexLogic entries available, numbered from 1 to 512, with default END entry settings. If a "Disabled" element
is selected as a FlexLogic entry, the associated state flag is never set to ‘1’. Press the +/– key when editing FlexLogic
equations to quickly scan through the major parameter types.

FUNCTION: Disabled
A FlexElement is a universal comparator used to monitor any analog actual value calculated by the relay or a net
difference of any two analog actual values of the same type. The effective operating signal can be treated as a signed
number or its absolute value can be used.
FlexElements run every half power cycle (every four protection passes).
The element can be programmed to respond either to a signal level or to a rate-of-change (delta) over a pre-defined period 5
of time. The output operand is asserted when the operating signal is higher than a threshold or lower than a threshold, as
per your choice.

FLEXELEMENT 1 +IN — This setting specifies the first (non-inverted) input to the FlexElement. Zero is assumed as the input if
this setting is set to “Off.” For proper operation of the element, at least one input must be selected. Otherwise, the element
does not assert its output operands.
FLEXELEMENT 1 –IN — Specifies the second (inverted) input to the FlexElement. Zero is assumed as the input if this setting is
set to “Off.” For proper operation of the element, at least one input must be selected. Otherwise, the element does not
assert its output operands. This input is used to invert the signal if needed for convenience, or to make the element
respond to a differential signal, such as for a top-bottom oil temperature differential alarm. The element does not operate
if the two input signals are of different types, for example if one tries to use active power and phase angle to build the
effective operating signal.
The element responds directly to the differential signal if the FLEXELEMENT 1 INPUT MODE setting is set to “Signed” The
element responds to the absolute value of the differential signal if this setting is set to “Absolute.” Sample applications for
the “Absolute” setting include monitoring the angular difference between two phasors with a symmetrical limit angle in
both directions; monitoring power regardless of its direction, or monitoring a trend regardless of whether the signal
increases of decreases.
The element responds directly to its operating signal—as defined by the FLEXELEMENT 1 +IN, FLEXELEMENT 1 –IN and
FLEXELEMENT 1 INPUT MODE settings—if the FLEXELEMENT 1 COMP MODE setting is set to “Level.” The element responds to the
rate of change of its operating signal if the FLEXELEMENT 1 COMP MODE setting is set to “Delta.” In this case, the
FLEXELEMENT 1 dt UNIT and FLEXELEMENT 1 dt settings specify how the rate of change is derived.
FLEXELEMENT 1 DIRECTION — Enables the relay to respond to either high or low values of the operating signal. The following

FLEXELEMENT 1 PICKUP — This setting specifies the operating threshold for the effective operating signal of the element. If
set to “Over,” the element picks up when the operating signal exceeds the FLEXELEMENT 1 PICKUP value. If set to “Under,” the
element picks up when the operating signal falls below the FLEXELEMENT 1 PICKUP value.
FLEXELEMENT 1 HYSTERESIS — This setting controls the element dropout. Notice that both the operating signal and the
pickup threshold can be negative, facilitating applications such as reverse power alarm protection. The FlexElement can be
programmed to work with all analog actual values measured by the relay. The FLEXELEMENT 1 PICKUP setting is entered in
per-unit values using the following definitions of the base units.

FLEXELEMENT 1 HYSTERESIS — This setting defines the pickup–dropout relation of the element by specifying the width of the
hysteresis loop as a percentage of the pickup value as shown in the FlexElement Direction, Pickup, and Hysteresis diagram.
FLEXELEMENT 1 dt UNIT — Specifies the time unit for the setting FLEXELEMENT 1 dt . This setting is applicable only if
FLEXELEMENT 1 COMP MODE is set to “Delta.”
FLEXELEMENT 1 dt — Specifies duration of the time interval for the rate of change mode of operation. This setting is
applicable only if FLEXELEMENT 1 COMP MODE is set to “Delta.”
FLEXELEMENT 1 PKP DELAY — Specifies the pickup delay of the element.
FLEXELEMENT 1 RST DELAY — Specifies the reset delay of the element.
The non-volatile latches provide a permanent logical flag that is stored safely and do not reset upon restart after the relay
is powered down. Typical applications include sustaining operator commands or permanently blocking relay functions,
such as Autorecloser, until a deliberate interface action resets the latch.
LATCH 1 TYPE — This setting characterizes Latch 1 to be Set- or Reset-dominant.
LATCH 1 SET — If asserted, the specified FlexLogic operands 'sets' Latch 1.
LATCH 1 RESET — If asserted, the specified FlexLogic operand 'resets' Latch 1.
The trip bus element allows aggregating outputs of protection and control elements without using FlexLogic and assigning
them a simple and effective manner. Each trip bus can be assigned for either trip or alarm actions. Simple trip conditioning
such as latch, delay, and seal-in delay are available.
The easiest way to assign element outputs to a trip bus is through the EnerVista software A protection summary is
displayed by navigating to a specific protection or control protection element and checking the desired bus box. Once the
desired element is selected for a specific bus, a list of element operate-type operands are displayed and can be assigned
to a trip bus. If more than one operate-type operand is required, it can be assigned directly from the trip bus menu.

The following settings are available.
TRIP BUS 1 BLOCK — The trip bus output is blocked when the operand assigned to this setting is asserted.
TRIP BUS 1 PICKUP DELAY — This setting specifies a time delay to produce an output depending on how output is used.
TRIP BUS 1 RESET DELAY — This setting specifies a time delay to reset an output command. Set the time delay long enough
to allow the breaker or contactor to perform a required action.
TRIP BUS 1 INPUT 1 to TRIP BUS 1 INPUT 16 — These settings select a FlexLogic operand to be assigned as an input to the trip
bus.
TRIP BUS 1 LATCHING — This setting enables or disables latching of the trip bus output. This is typically used when lockout is
required or user acknowledgement of the relay response is required.
TRIP BUS 1 RESET — The trip bus output is reset when the operand assigned to this setting is asserted. Note that the RESET OP
operand is pre-wired to the reset gate of the latch, As such, a reset command from the front panel interface or via
communications resets the trip bus output.

The selector switch element is intended to replace a mechanical selector switch. Typical applications include setting group
control or control of multiple logic sub-circuits in user-programmable logic.
The element provides for two control inputs. The step-up control allows stepping through selector position one step at a
time with each pulse of the control input, such as a user-programmable pushbutton. The three-bit control input allows
setting the selector to the position defined by a three-bit word.
The element allows pre-selecting a new position without applying it. The pre-selected position gets applied either after
time-out or upon acknowledgement via separate inputs (user setting). The selector position is stored in non-volatile
memory. Upon power-up, either the previous position is restored or the relay synchronizes to the current three-bit word
(user setting). Basic alarm functionality alerts the user under abnormal conditions; for example, the three-bit control input
being out of range.
A selector switch runs every two power cycles.
SELECTOR 1 FULL RANGE — This setting defines the upper position of the selector. When stepping up through available
positions of the selector, the upper position wraps up to the lower position (position 1). When using a direct three-bit control
word for programming the selector to a desired position, the change would take place only if the control word is within the
range of 1 to the SELECTOR FULL RANGE. If the control word is outside the range, an alarm is established by setting the
SELECTOR ALARM FlexLogic operand for three seconds.
SELECTOR 1 TIME-OUT — This setting defines the time-out period for the selector. This value is used by the relay in the
following two ways. When the SELECTOR STEP-UP MODE is “Time-out,” the setting specifies the required period of inactivity
of the control input after which the pre-selected position is automatically applied. When the SELECTOR STEP-UP MODE is
5 “Acknowledge,” the setting specifies the period of time for the acknowledging input to appear. The timer is re-started by
any activity of the control input. The acknowledging input must come before the SELECTOR 1 TIME-OUT timer expires;
otherwise, the change does not take place and an alarm is set.
SELECTOR 1 STEP-UP — This setting specifies a control input for the selector switch. The switch is shifted to a new position at
each rising edge of this signal. The position changes incrementally, wrapping up from the last (SELECTOR 1 FULL RANGE) to
the first (position 1). Consecutive pulses of this control operand must not occur faster than every 50 ms. After each rising
edge of the assigned operand, the time-out timer is restarted and the SELECTOR SWITCH 1: POS Z CHNG INITIATED target
message is displayed, where Z the pre-selected position. The message is displayed for the time specified by the FLASH
MESSAGE TIME setting. The pre-selected position is applied after the selector times out (“Time-out” mode), or when the
acknowledging signal appears before the element times out (“Acknowledge” mode). When the new position is applied, the
relay displays the SELECTOR SWITCH 1: POSITION Z IN USE message. Typically, a user-programmable pushbutton is
configured as the stepping up control input.
SELECTOR 1 STEP-UP MODE — This setting defines the selector mode of operation. When set to “Time-out,” the selector
changes its position after a pre-defined period of inactivity at the control input. The change is automatic and does not
require any explicit confirmation of the intent to change the selector's position. When set to “Acknowledge,” the selector
changes its position only after the intent is confirmed through a separate acknowledging signal. If the acknowledging
signal does not appear within a pre-defined period of time, the selector does not accept the change and an alarm is
established by setting the SELECTOR STP ALARM output FlexLogic operand for three seconds.
SELECTOR 1 ACK — This setting specifies an acknowledging input for the stepping up control input. The pre-selected
position is applied on the rising edge of the assigned operand. This setting is active only under “Acknowledge” mode of
operation. The acknowledging signal must appear within the time defined by the SELECTOR 1 TIME-OUT setting after the last
activity of the control input. A user-programmable pushbutton is typically configured as the acknowledging input.
SELECTOR 1 3BIT A0, A1, and A2 — These settings specify a three-bit control input of the selector. The three-bit control word
pre-selects the position using the following encoding convention:
A2 A1 A0 Position
0 0 0 rest
0 0 1 1
0 1 0 2
0 1 1 3
1 0 0 4
1 0 1 5
1 1 0 6
1 1 1 7
The “rest” position (0, 0, 0) does not generate an action and is intended for situations when the device generating the three-
bit control word is having a problem. When SELECTOR 1 3BIT MODE is “Time-out,” the pre-selected position is applied in
SELECTOR 1 TIME-OUT seconds after the last activity of the three-bit input. When SELECTOR 1 3BIT MODE is “Acknowledge,”
the pre-selected position is applied on the rising edge of the SELECTOR 1 3BIT ACK acknowledging input.
The stepping up control input (SELECTOR 1 STEP-UP) and the three-bit control inputs (SELECTOR 1 3BIT A0 through A2) lock-out
mutually: once the stepping up sequence is initiated, the three-bit control input is inactive; once the three-bit control
sequence is initiated, the stepping up input is inactive.
SELECTOR 1 3BIT MODE — This setting defines the selector mode of operation. When set to “Time-out,” the selector changes
its position after a pre-defined period of inactivity at the control input. The change is automatic and does not require
explicit confirmation to change the selector position. When set to “Acknowledge,” the selector changes its position only
after confirmation via a separate acknowledging signal. If the acknowledging signal does not appear within a pre-defined
period of time, the selector rejects the change and an alarm established by invoking the SELECTOR BIT ALARM FlexLogic operand 5
for three seconds.
SELECTOR 1 3BIT ACK — This setting specifies an acknowledging input for the three-bit control input. The pre-selected
position is applied on the rising edge of the assigned FlexLogic operand. This setting is active only under the
“Acknowledge” mode of operation. The acknowledging signal must appear within the time defined by the SELECTOR TIME-
OUT setting after the last activity of the three-bit control inputs. Note that the stepping up control input and three-bit
control input have independent acknowledging signals (SELECTOR 1 ACK and SELECTOR 1 3BIT ACK , accordingly).
SELECTOR 1 POWER-UP MODE — This setting specifies the element behavior on power up of the relay.
When set to “Restore,” the last position of the selector (stored in the non-volatile memory) is restored after powering up the
relay. If the position restored from memory is out of range, position 0 (no output operand selected) is applied and an alarm
is set (SELECTOR 1 PWR ALARM).
When set to “Synchronize,” the selector switch acts as follows. For two power cycles, the selector applies position 0 to the
switch and activates SELECTOR 1 PWR ALARM. After two power cycles expire, the selector synchronizes to the position
dictated by the three-bit control input. This operation does not wait for time-out or the acknowledging input. When the
synchronization attempt is unsuccessful (that is, the three-bit input is not available (0,0,0) or out of range), then the selector
switch output is set to position 0 (no output operand selected) and an alarm is established (SELECTOR 1 PWR ALARM).
The operation of “Synch/Restore” mode is similar to the “Synchronize” mode. The only difference is that after an
unsuccessful synchronization attempt, the switch attempts to restore the position stored in the relay memory. The “Synch/
Restore” mode is useful for applications where the selector switch is employed to change the setting group in redundant
(two relay) protection schemes.
SELECTOR 1 EVENTS — If enabled, the following events are logged:
The following figures illustrate the operation of the selector switch. In these diagrams, “T” represents a time-out setting.

Application example
Consider an application where the selector switch is used to control setting groups 1 through 4 in the relay. The setting
groups are to be controlled from both user-programmable pushbutton 1 and from an external device via contact inputs 1
through 3. The active setting group is to be available as an encoded three-bit word to the external device and SCADA via
output contacts 1 through 3. The pre-selected setting group is to be applied automatically after five seconds of inactivity
of the control inputs. When the relay powers up, it is to synchronize the setting group to the three-bit control input.
Make the following changes to setting group control in the SETTINGS CONTROL ELEMENTS SETTING GROUPS menu:

There are 48 identical digital elements available, numbered 1 to 48. A digital element can monitor any FlexLogic operand
and present a target message and/or enable events recording depending on the output operand state. The digital element
settings include a name to be referenced in any target message, a blocking input from any selected FlexLogic operand,
and a timer for pickup and reset delays for the output operand.
DIGITAL ELEMENT 1 INPUT — Selects a FlexLogic operand to be monitored by the digital element.
DIGITAL ELEMENT 1 PICKUP DELAY — Sets the required time delay from element pickup to element operation. If a pickup delay
is not required, set to "0," To avoid nuisance alarms, set the delay greater than the operating time of the breaker.
DIGITAL ELEMENT 1 RESET DELAY — Sets the time delay to reset. If a reset delay is not required, set to “0.”

COUNTER 1
FUNCTION: Disabled

There are eight identical digital counters, numbered from 1 to 8. A digital counter counts the number of state transitions
from Logic 0 to Logic 1. The counter is used to count operations such as the pickups of an element, the changes of state of
an external contact (for example, breaker auxiliary switch), or pulses from a watt-hour meter.
COUNTER 1 UNITS — Assigns a label to identify the unit of measure pertaining to the digital transitions to be counted. The
units label appears in the corresponding actual values status.
COUNTER 1 PRESET — Sets the count to a required preset value before counting operations begin, as in the case where a
substitute relay is to be installed in place of an in-service relay, or while the counter is running.
COUNTER 1 COMPARE — Sets the value to which the accumulated count value is compared. Three FlexLogic output
operands are provided to indicate if the present value is ‘more than (HI)’, ‘equal to (EQL)’, or ‘less than (LO)’ the set value.
COUNTER 1 UP — Selects the FlexLogic operand for incrementing the counter. If an enabled UP input is received when the
accumulated value is at the limit of +2,147,483,647 counts, the counter rolls over to –2,147,483,648.
COUNTER 1 DOWN — Selects the FlexLogic operand for decrementing the counter. If an enabled DOWN input is received
when the accumulated value is at the limit of –2,147,483,648 counts, the counter rolls over to +2,147,483,647.
COUNTER 1 BLOCK — Selects the FlexLogic operand for blocking the counting operation. All counter operands are blocked.
CNT1 SET TO PRESET — Selects the FlexLogic operand used to set the count to the preset value. The counter sets to the
preset value in the following situations:
• When the counter is enabled and the CNT1 SET TO PRESET operand has the value 1 (when the counter is enabled and
CNT1 SET TO PRESET operand is 0, the counter sets to 0)
• When the counter is running and the CNT1 SET TO PRESET operand changes the state from 0 to 1 (CNT1 SET TO PRESET
changing from 1 to 0 while the counter is running has no effect on the count)
• When a reset or reset/freeze command is sent to the counter and the CNT1 SET TO PRESET operand has the value 1
(when a reset or reset/freeze command is sent to the counter and the CNT1 SET TO PRESET operand has the value 0, the
counter sets to 0)
COUNTER 1 RESET — Selects the FlexLogic operand for setting the count to either “0” or the preset value depending on the
state of the CNT1 SET TO PRESET operand.
COUNTER 1 FREEZE/RESET — Selects the FlexLogic operand for capturing (freezing) the accumulated count value into a 5
separate register with the date and time of the operation, and resetting the count to “0.”
COUNTER 1 FREEZE/COUNT — Selects the FlexLogic operand for capturing (freezing) the accumulated count value into a
separate register with the date and time of the operation, and continuing counting. The present accumulated value and
captured frozen value with the associated date/time stamp are available as actual values. If control power is interrupted,
the accumulated and frozen values are saved into non-volatile memory during the power-down operation.

This feature allows switching between two input arguments defined by 8 bits each. The bits are specified by FlexLogic
operands. The feature could be viewed as an integrated two-position switch for 8 logic signals.
Typically this element is applied in conjunction with the Digitizer and 8-bit Comparator features.
The switch runs every half power cycle (every four protection passes).
8BIT SW 1 ARG A0 to 8BIT SW 1 ARG A7 — These settings specify FlexLogic operands that constitute the first (A) input of the
switch. These operands are routed to the output operands if the control input is in the "Off" position.
BIT SW 1 ARG B0 to 8BIT SW 1 ARG B7 — These settings specify FlexLogic operands that constitute the second (B) input of the
switch. These operands are routed to the output operands if the control input is in the "On" position.
8BIT SW 1 CONTROL — This setting specifies FlexLogic operands to control the routing between the A and B inputs of the
switch. If the control operand is in the "Off" state, the first (A) input is switched to the output. If the control operand is in the
"On" state, the second (B) input is switched to the output. The switching takes place instantaneously.

SETTINGS INPUTS/OUTPUTS CONTACT INPUTS
CONTACT INPUTS
CONTACT INPUT
THRESHOLDS
A contact inputs and outputs are digital signals associated with connections to hard-wired contacts. Wet and dry contacts
are supported.
The contact inputs menu contains configuration settings for each contact input as well as voltage thresholds for each
group of four contact inputs. Upon startup, the relay processor determines (from an assessment of the installed modules)
which contact inputs are available and then display settings for only those inputs.
An alphanumeric ID can be assigned to a contact input for diagnostic, setting, and event recording purposes. The CONTACT IP
X On (Logic 1) FlexLogic operand corresponds to contact input “X” being closed, while CONTACT IP X Off corresponds to contact
input “X” being open. The CONTACT INPUT DEBNCE TIME defines the time required for the contact to overcome ‘contact
bouncing’ conditions. As this time differs for different contact types and manufacturers, set it as a maximum contact
debounce time (per manufacturer specifications) plus some margin to ensure proper operation. If CONTACT INPUT EVENTS is
set to “Enabled,” every change in the contact input state triggers an event.
A raw status is scanned for all Contact Inputs synchronously at the constant rate of 0.5 ms as shown in the following
figure. The DC input voltage is compared to a user-settable threshold. A new contact input state must be maintained for a
user-settable debounce time in order for the C30 to validate the new contact state. In the following figure, the debounce
time is set at 2.5 ms; thus the 6th sample in a row validates the change of state (mark no. 1 in the diagram). Once validated
(de-bounced), the contact input asserts a corresponding FlexLogic operand and logs an event as per user setting.
5
A time stamp of the first sample in the sequence that validates the new state is used when logging the change of the
contact input into the Event Recorder (mark no. 2 in the figure).
Protection and control elements, as well as FlexLogic equations and timers, are executed eight times in a power system
cycle. The protection pass duration is controlled by the frequency tracking mechanism. The FlexLogic operand reflecting
the debounced state of the contact is updated at the protection pass following the validation (marks no. 3 and 4 on the
figure below). The update is performed at the beginning of the protection pass so all protection and control functions, as
well as FlexLogic equations, are fed with the updated states of the contact inputs.
The FlexLogic operand response time to the contact input change is equal to the debounce time setting plus up to one
protection pass (variable and depending on system frequency if frequency tracking enabled). If the change of state occurs
just after a protection pass, the recognition is delayed until the subsequent protection pass; that is, by the entire duration
of the protection pass. If the change occurs just prior to a protection pass, the state is recognized immediately. Statistically
a delay of half the protection pass is expected. Owing to the 0.5 ms scan rate, the time resolution for the input contact is
below 1 ms.
For example, eight protection passes per cycle on a 60 Hz system correspond to a protection pass every 2.1 ms. With a
contact debounce time setting of 3.0 ms, the FlexLogic operand-assert time limits are: 3.0 + 0.0 = 3.0 ms and 3.0 + 2.1 = 5.1
ms. These time limits depend on how soon the protection pass runs after the debouncing time.
Regardless of the contact debounce time setting, the contact input event is time-stamped with a 1 μs accuracy using the
time of the first scan corresponding to the new state (mark no. 2 shown). Therefore, the time stamp reflects a change in the
DC voltage across the contact input terminals that was not accidental as it was subsequently validated using the
debounce timer. Keep in mind that the associated FlexLogic operand is asserted/de-asserted later, after validating the
change.
The debounce algorithm is symmetrical: the same procedure and debounce time are used to filter the LOW-HIGH (marks
no.1, 2, 3, and 4 in the figure) and HIGH-LOW (marks no. 5, 6, 7, and 8) transitions.

Contact inputs are isolated in groups of four to allow connection of wet contacts from different voltage sources for each
group. The CONTACT INPUT THRESHOLDS determine the minimum voltage required to detect a closed contact input. This
value is selected according to the following criteria: 17 for 24 V sources, 33 for 48 V sources, 84 for 110 to 125 V sources
and 166 for 250 V sources.
For example, to use contact input H5a as a status input from the breaker 52b contact to seal-in the trip relay and record it
in the Event Records menu, make the following settings changes:
CONTACT INPUT H5a ID: "Breaker Closed (52b)"
CONTACT INPUT H5a EVENTS: "Enabled"
Note that the 52b contact is closed when the breaker is open and open when the breaker is closed.
The virtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs include
signals generated by the local user interface. The virtual outputs are outputs of FlexLogic™ equations used to customize
the device. Virtual outputs can also serve as virtual inputs to FlexLogic equations.
There are 64 virtual inputs that can be individually programmed to respond to input signals from the keypad (via the
COMMANDS menu) and communications protocols. All virtual input operands are defaulted to “Off” (logic 0) unless the
appropriate input signal is received.
If the VIRTUAL INPUT x FUNCTION is to “Disabled,” the input is forced to off (logic 0) regardless of any attempt to alter the
input. If set to “Enabled,” the input operates as shown on the logic diagram and generates output FlexLogic operands in
response to received input signals and the applied settings.
There are two types of operation: self-reset and latched. If VIRTUAL INPUT x type is “Self-Reset,” when the input signal
transits from off to on, the output operand is set to on for only one evaluation of the FlexLogic equations and then return to
off. If set to “Latched,” the virtual input sets the state of the output operand to the same state as the most recent received
input.
The self-reset operating mode generates the output operand for a single evaluation of the FlexLogic equations. If the
operand is to be used anywhere other than internally in a FlexLogic equation, it likely needs to be lengthened in time. A
FlexLogic timer with a delayed reset can perform this function.

A contact inputs and outputs are digital signals associated with connections to hard-wired contacts. Wet and dry contacts
are supported.
Upon startup of the relay, the main processor determines from an assessment of the modules installed in the chassis
which contact outputs are available and then present the settings for only these outputs.
An ID can be assigned to each contact output. The signal that can OPERATE a contact output can be any FlexLogic operand
(virtual output, element state, contact input, or virtual input). An additional FlexLogic operand can be used to SEAL-IN the
relay. Any change of state of a contact output can be logged as an Event if programmed to do so.
For example, the trip circuit current is monitored by providing a current threshold detector in series with some Form-A
contacts (see the trip circuit example in the Digital Elements section). The monitor sets a flag (see the specifications for
Form-A). The name of the FlexLogic operand set by the monitor, consists of the output relay designation, followed by the
name of the flag; for example, Cont OP 1 IOn.
In most breaker control circuits, the trip coil is connected in series with a breaker auxiliary contact used to interrupt current
flow after the breaker has tripped, to prevent damage to the less robust initiating contact. This can be done by monitoring
an auxiliary contact on the breaker which opens when the breaker has tripped, but this scheme is subject to incorrect
operation caused by differences in timing between breaker auxiliary contact change-of-state and interruption of current in
the trip circuit. The most dependable protection of the initiating contact is provided by directly measuring current in the
tripping circuit, and using this parameter to control resetting of the initiating relay. This scheme is often called trip seal-in.
This can be realized in the C30 using the Cont OP 1 IOn FlexLogic operand to seal-in the contact output as follows:
CONTACT OUTPUT H1 ID: “Cont Op 1"
OUTPUT H1 OPERATE: any suitable FlexLogic operand
OUTPUT H1 SEAL-IN: “Cont Op 1 IOn”
CONTACT OUTPUT H1 EVENTS: “Enabled”
The C30 latching output contacts are mechanically bi-stable and controlled by two separate (open and close) coils. As such
they retain their position even if the relay is not powered up. The relay recognizes all latching output contact cards and
populates the setting menu accordingly. On power up, the relay reads positions of the latching contacts from the hardware
before executing any other functions of the relay (such as protection and control features or FlexLogic).
The latching output modules, either as a part of the relay or as individual modules, are shipped from the factory with all
latching contacts opened. It is highly recommended to double-check the programming and positions of the latching
contacts when replacing a module.
Since the relay asserts the output contact and reads back its position, it is possible to incorporate self-monitoring
capabilities for the latching outputs. If any latching outputs exhibits a discrepancy, the LATCHING OUTPUT ERROR self-test
error is declared. The error is signaled by the LATCHING OUT ERROR FlexLogic operand, event, and target message.
OUTPUT H1a OPERATE — This setting specifies a FlexLogic operand to operate the ‘close coil’ of the contact. The relay seals-
in this input to safely close the contact. Once the contact is closed and the RESET input is logic 0 (off), any activity of the
OPERATE input, such as subsequent chattering, does not have any effect. With both the OPERATE and RESET inputs active
(logic 1), the response of the latching contact is specified by the OUTPUT H1a TYPE setting.
OUTPUT H1a RESET — This setting specifies a FlexLogic operand to operate the ‘trip coil’ of the contact. The relay seals-in
this input to safely open the contact. Once the contact is opened and the OPERATE input is logic 0 (off), any activity of the
RESET input, such as subsequent chattering, does not have any effect. With both the OPERATE and RESET inputs active (logic
1), the response of the latching contact is specified by the OUTPUT H1a TYPE setting.
OUTPUT H1a TYPE — This setting specifies the contact response under conflicting control inputs; that is, when both the
OPERATE and RESET signals are applied. With both control inputs applied simultaneously, the contact closes if set to
“Operate-dominant” and opens if set to “Reset-dominant.”
Application example 1
A latching output contact H1a is to be controlled from two user-programmable pushbuttons (buttons number 1 and 2). The
following settings are applied.
Program the Latching Outputs by making the following changes in the SETTINGS INPUTS/OUTPUTS CONTACT
OUTPUTS CONTACT OUTPUT H1a menu (assuming an H4L module):
OUTPUT H1a OPERATE: “PUSHBUTTON 1 ON”
OUTPUT H1a RESET: “PUSHBUTTON 2 ON”

PUSHBUTTON 1 FUNCTION: “Self-reset”
PUSHBTN 1 DROP-OUT TIME: “0.00 s”
PUSHBUTTON 2 FUNCTION: “Self-reset”
PUSHBTN 2 DROP-OUT TIME: “0.00 s”
Application example 2
A relay, having two latching contacts H1a and H1c, is to be programmed. The H1a contact is to be a Type-a contact, while
the H1c contact is to be a Type-b contact (Type-a means closed after exercising the operate input; Type-b means closed
after exercising the reset input). The relay is to be controlled from virtual outputs: VO1 to operate and VO2 to reset.
Program the Latching Outputs by making the following changes in the SETTINGS INPUTS/OUTPUTS CONTACT
OUTPUTS CONTACT OUTPUT H1a and CONTACT OUTPUT H1c menus (assuming an H4L module):
OUTPUT H1a OPERATE: “VO1”
OUTPUT H1a RESET: “VO2”
OUTPUT H1c OPERATE: “VO2”
OUTPUT H1c RESET: “VO1” 5
Since the two physical contacts in this example are mechanically separated and have individual control inputs, they do not
operate at exactly the same time. A discrepancy in the range of a fraction of a maximum operating time can occur.
Therefore, a pair of contacts programmed to be a multi-contact relay do not guarantee any specific sequence of operation
(such as make before break). If required, the sequence of operation must be programmed explicitly by delaying some of the
control inputs as shown in the next application example.
Application example 3
A make before break functionality must be added to the preceding example. An overlap of 20 ms is required to implement
this functionality.
Write the following FlexLogic equation (EnerVista example shown).
Application example 4
A latching contact H1a is to be controlled from a single virtual output VO1. The contact is to remain closed as long as VO1
is high, and is to remain opened when VO1 is low. Program the relay as follows.
Write the following FlexLogic equation (EnerVista example shown).
Program the Latching Outputs by making the following changes in the SETTINGS INPUTS/OUTPUTS CONTACT

The virtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs include
signals generated by the local user interface. The virtual outputs are outputs of FlexLogic™ equations used to customize
the device. Virtual outputs can also serve as virtual inputs to FlexLogic equations.
There are 96 virtual outputs that can be assigned using FlexLogic. If not assigned, the output is forced to ‘OFF’ (Logic 0). An
ID also can be assigned to each virtual output. Virtual outputs are resolved in each pass through the evaluation of the
FlexLogic equations. Any change of state of a virtual output can be logged as an event if programmed to do so.
For example, if Virtual Output 1 is the trip signal from FlexLogic and the trip relay is used to signal events, the settings is
programmed as follows:
VIRTUAL OUTPUT 1 ID: "Trip"
VIRTUAL OUTPUT 1 EVENTS: "Disabled"
5.8.5 Resetting
SETTINGS INPUTS/OUTPUTS RESETTING

Some events can be programmed to latch the faceplate LED event indicators and the target message on the display. Once
set, the latching mechanism holds all of the latched indicators or messages in the set state after the initiating condition
has cleared until a RESET command is received to return these latches (not including FlexLogic latches) to the reset state.
The RESET command can be sent from the faceplate RESET button, a remote device via a communications channel, or any
programmed operand.
When the RESET command is received by the relay, two FlexLogic operands are created. These operands, which are stored
as events, reset the latches if the initiating condition has cleared. The three sources of RESET commands each create the
RESET OP FlexLogic operand. Each individual source of a RESET command also creates its individual operand RESET OP
(PUSHBUTTON), RESET OP (COMMS) or RESET OP (OPERAND) to identify the source of the command. The RESET OPERAND setting here
selects the operand that creates the RESET OP (OPERAND) operand.
DIRECT OUT 1 NAME — This setting allows the user to assign a descriptive name to the direct output.
DIR OUT 1 OPERAND — This sets the FlexLogic operand that determines the state of this direct output.

5.8.7 Teleprotection
5.8.7.1 Overview 5
The relay provides 16 teleprotection inputs on communications channel 1 (numbered 1-1 through 1-16) and 16
teleprotection inputs on communications channel 2 (on two-terminals two-channel and three-terminal systems only,
numbered 2-1 through 2-16). The remote relay connected to channels 1 and 2 of the local relay is programmed by
assigning FlexLogic operands to be sent via the selected communications channel. This allows the user to create
distributed protection and control schemes via dedicated communications channels. Some examples are directional
comparison pilot schemes and direct transfer tripping. Note that failures of communications channels affect
teleprotection functionality. The teleprotection function must be enabled to utilize the inputs.
Setting the TELEPROT INPUT ~~ DEFAULT setting to “On” defaults the input to logic 1 when the channel fails. A value of “Off”
defaults the input to logic 0 when the channel fails.
The “Latest/On” and “Latest/Off” values freeze the input in case of lost communications. If the latest state is not known,
such as after relay power-up but before the first communication exchange, then the input defaults to logic 1 for “Latest/
On” and logic 0 for “Latest/Off.”
As the following figure demonstrates, processing of the teleprotection inputs/outputs is dependent on the number of
communication channels and terminals. On two-terminal two-channel systems, they are processed continuously on each
channel and mapped separately per channel. Therefore, to achieve redundancy, the user must assign the same operand
on both channels (teleprotection outputs at the sending end or corresponding teleprotection inputs at the receiving end).
On three-terminal two-channel systems, redundancy is achieved by programming signal re-transmittal in the case of
channel failure between any pair of relays.

The C30 is provided with optional DCmA capability. This feature is specified as an option at the time of
ordering. See the Order Codes section in chapter 2 for details.

Hardware and software are provided to receive signals from external transducers and to convert these signals into a
digital format for use as required. The relay accepts inputs in the range of –1 to +20 mA DC, suitable for use with most
common transducer output ranges; all inputs are assumed to be linear over the complete range. Hardware details are
contained in chapter 3.
Before the DCmA input signal can be used, the value of the signal measured by the relay must be converted to the range
and quantity of the external transducer primary input parameter, such as DC voltage or temperature. The relay simplifies
this process by internally scaling the output from the external transducer and displaying the actual primary parameter.
DCmA input channels are arranged in a manner similar to CT and VT channels. Configure the individual channels with the
settings shown here.
The channels are arranged in sub-modules of two channels, numbered from 1 through 8 from top to bottom. On power-up,
the relay automatically generates configuration settings for every channel, based on the order code, in the same general
manner that is used for CTs and VTs. Each channel is assigned a slot letter followed by the row number, 1 through 8
inclusive, which is used as the channel number. The relay generates an actual value for each available input channel.
Settings are generated automatically for every channel available in the specific relay as shown above for the first channel
of a type 5F transducer module installed in slot F.
The function of the channel can be “Enabled” or “Disabled.” If “Disabled,” no actual values are created for the channel. An
alphanumeric “ID” is assigned to each channel; this ID is included in the channel actual value, along with the programmed
units associated with the parameter measured by the transducer, such as volts, °C, megawatts, and so on. This ID is also
used to reference the channel as the input parameter to features designed to measure this type of parameter. The DCMA
INPUT F1 RANGE setting specifies the mA DC range of the transducer connected to the input channel.
The DCMA INPUT F1 MIN VALUE and DCMA INPUT F1 MAX VALUE settings are used to program the span of the transducer in
primary units. For example, a temperature transducer might have a span from 0 to 250 °C; in this case the DCMA INPUT F1
MIN VALUE value is “0” and the DCMA INPUT F1 MAX VALUE value is “250.” Another example is a watts transducer with a span
from –20 to +180 MW; in this case the DCMA INPUT F1 MIN VALUE value is “–20” and the DCMA INPUT F1 MAX VALUE value is
“180.” Intermediate values between the minimum and maximum values are scaled linearly.
RTD INPUT F1 TYPE: Range: 100Ω Nickel, 10Ω Copper, 100Ω Platinum,
100Ω Nickel 120Ω Nickel
Hardware and software is provided to receive signals from external resistance temperature detectors and convert these
signals into a digital format for use as required. These channels are intended to be connected to any of the RTD types in
common use. Specific hardware details are contained in chapter 3.
RTD input channels are arranged in a manner similar to CT and VT channels. The user configures individual channels with
the settings shown here.
The channels are arranged in sub-modules of two channels, numbered from 1 through 8 from top to bottom. On power-up,
the relay automatically generates configuration settings for every channel, based on the order code, in the same general
manner that is used for CTs and VTs. Each channel is assigned a slot letter followed by the row number, 1 through 8
inclusive, which is used as the channel number. The relay generates an actual value for each available input channel.
Settings are automatically generated for every channel available in the specific relay as shown above for the first channel
of a type 5C transducer module installed in the first available slot.
The function of the channel can be either “Enabled” or “Disabled.” If “Disabled,” there is not an actual value created for the
channel. An alphanumeric ID is assigned to the channel; this ID is included in the channel actual values. It is also used to
5 reference the channel as the input parameter to features designed to measure this type of parameter. Selecting the type of
RTD connected to the channel configures the channel.
Actions based on RTD overtemperature, such as trips or alarms, are done in conjunction with the FlexElements feature. In
FlexElements, the operate level is scaled to a base of 100°C. For example, a trip level of 150°C is achieved by setting the
operate level at 1.5 pu. FlexElement operands are available to FlexLogic for further interlocking or to operate an output
contact directly.
See the following table for reference temperature values for each RTD type.
Hardware and software is provided to generate DCmA signals that allow interfacing with external equipment. Hardware
details are contained in chapter 3. The DCmA output channels are arranged in a manner similar to transducer input or CT
and VT channels. The user configures individual channels with the settings as follows.
The channels are arranged in sub-modules of two channels, numbered 1 through 8 from top to bottom. On power-up, the
relay automatically generates configuration settings for every channel, based on the order code, in the same manner used
for CTs and VTs. Each channel is assigned a slot letter followed by the row number, 1 through 8 inclusive, which is used as
the channel number.
Both the output range and a signal driving a given output are user-programmable via the following settings menu (an
example for channel M5 is shown).
The relay checks the driving signal (x in equations below) for the minimum and maximum limits, and subsequently re-
scales so the limits defined as MIN VAL and MAX VAL match the output range of the hardware defined as RANGE. The
following equation is applied:
where
x is a driving signal specified by the SOURCE setting
Imin and Imax are defined by the RANGE setting
k is a scaling constant calculated as:

- Eq. 5-5

5 The feature is intentionally inhibited if the MAX VAL and MIN VAL settings are entered incorrectly, for example when MAX VAL
– MIN VAL < 0.1 pu. The resulting characteristic is illustrated in the following figure.

DCMA OUTPUT F1 RANGE — This setting allows selection of the output range. Each DCmA channel can be set independently
to work with different ranges. The three most commonly used output ranges are available.
DCMA OUTPUT F1 MIN VAL — This setting allows setting the minimum limit for the signal that drives the output. This setting is
used to control the mapping between an internal analog value and the output current. The setting is entered in per-unit
values. The base units are defined in the same manner as the FlexElement base units.
DCMA OUTPUT F1 MAX VAL — This setting allows setting the maximum limit for the signal that drives the output. This setting
is used to control the mapping between an internal analog value and the output current. The setting is entered in per-unit
values. The base units are defined in the same manner as the FlexElement base units.
The DCMA OUTPUT F1 MIN VAL and DCMA OUTPUT F1 MAX VAL settings are ignored for power factor base units (i.e.
if the DCMA OUTPUT F1 SOURCE is set to FlexAnalog value based on power factor measurement).
NOTE
5.10 Testing
5.10.1 Test mode function
SETTINGS TESTING TEST MODE FUNCTION
TESTING TEST MODE Range: Disabled, Isolated, Forcible
FUNCTION: Disabled
The C30 provides a test facility to verify the functionality of contact inputs and outputs, some communication channels
and the phasor measurement unit (where applicable), using simulated conditions.
The test mode can be in any of three states: Disabled, Isolated, or Forcible.
The Disabled mode is intended for normal in service operation; relay protection, control and communication function is
normal. Test features are disabled, except channel tests and phasor measurement unit tests remain usable when
provided.
The Isolated mode is intended to allow the relay to be quickly placed in a state where the relay cannot negatively impact
5
the power system or other parts of the substation automation system. This is to allow changing settings, loading new
firmware, changing hardware modules, and changing communication connections. As far as practical all relay output
signals are blocked. Contact outputs are de-energized, latching outputs are frozen. Commands to bricks are blocked.
GOOSE transmissions have their "simulation" flag (also known as "test" flag) set, which results in the messages not being
accepted by compliant receiving devices that do not have a "Sim" data attribute set. The quality attribute of values that
can be output via 61850 MMS services are set to "invalid," which results in the values not being used for operational
purposes by compliant receiving devices.
The Forcible mode is intended for testing involving forcing relay operation by test signal injection and verifying correct
relay output. This mode is also for tests to verify the relay outputs (both contact and communications) have the intended
impact on specific power system devices or on specific other substation automation devices. Contact outputs can be
selectively enabled or forced as described in the following two sections. Shared outputs to bricks have their test mode flag
raised, which results in their value only being accepted by relays also in forcible mode. GOOSE transmissions have the
"simulation" flag set, which results in these only being accepted by other devices that have their "Sim" data attribute set.
The "Sim" data attribute in the relay is set, so that if GOOSE messages are received with the "simulation" flag set, these are
used in place of the normal messages. The quality attribute of values that are output via 61850 MMS services are set to
"valid" + "test," which signals that the values should not be used for operational purposes.
Otherwise, the UR remains fully operational while in the Forcible test mode, allowing for various testing procedures. In
particular, the protection and control elements, and FlexLogic function normally. Other than the IEC 61850 protocol,
communications based inputs and outputs remain fully operational. The test procedure must take this into account.
The test mode can be selected either through the front panel, through EnerVista UR Setup, or through IEC 61850 control to
LLN0.Mod. LLN0.Mod.ctlVal "on" selects Disabled, "test/blocked" selects Isolated, and "test" selects Forcible. The TEST MODE
FUNCTION setting can only be changed by a direct user command. Following a restart, power up, settings upload, or
firmware upgrade, the test mode remains at the last programmed value. This allows a UR that has been placed in isolated
mode to remain isolated during testing and maintenance activities.
The test mode state is indicated on the relay faceplate by a combination of the Test Mode LED indicator, the In-Service LED
indicator, and by the critical fail relay, as shown in the following table.
Table 5-21: Test mode operation
Test mode In-service Test mode Critical fail Test mode forcing Contact input and output behavior

On restart, the TEST MODE FORCING setting and the force contact input and force contact output settings revert
to their default states.
NOTE
The force contact inputs feature provides a method of performing checks on the function of all contact inputs.
While in Forcible test mode, the relay contact inputs can be pre-programmed to respond in the following ways:
• If set to “Normal,” the input remains fully operational. It is controlled by the voltage across its input terminals and can
be turned on and off by external circuitry. Select this value if a given input must be operational during the test. This
includes, for example, an input initiating the test, or being a part of a user pre-programmed test sequence.
• If set to “Open,” the input is forced to report as opened (Logic 0) while the operand selected by TEST MODE FORCING
setting is On, regardless of the voltage across the input terminals. While the selected operand is Off, the input behaves
as it does when in service.
• If set to “Closed,” the input is forced to report as closed (Logic 1) while the operand selected by TEST MODE FORCING
setting is On regardless of the voltage across the input terminals. While the selected operand is Off, the input behaves
as it does when in service.
On restart, the TEST MODE FORCING setting and the force contact input and force contact output settings revert
to their default states.
NOTE
The force contact outputs feature provides a method of performing checks on the function of all contact outputs.
While in Forcible test mode, the relay contact outputs can be pre-programmed to respond in the following ways:
• If set to “Normal,” the contact output remains fully operational. It operates when its control operand is logic 1 and
resets when its control operand is logic 0.
• If set to “Energized,” the output closes and remains closed while the operand selected by the TEST MODE FORCING
setting is On, regardless of the status of the operand configured to control the output contact. While the selected
operand is Off, the output behaves as it does when in service.
• If set to “De-energized,” the output opens and remains opened while the operand selected by the TEST MODE FORCING
setting is On, regardless of the status of the operand configured to control the output contact. While the selected
operand is Off, the output behaves as it does when in service.
• If set to “Freeze,” the output retains its position at the instant before the TEST MODE FUNCTION was Forcible and the
operand selected by the TEST MODE FORCING setting was On, regardless of later changes in the status of the operand
configured to control the output contact. While the selected operand is Off, the output behaves as it does when in
service.

6.2.13 Ethernet
ACTUAL VALUES STATUS ETHERNET
ETHERNET ETHERNET PRI LINK Range: Fail, OK
STATUS: Fail
These values indicate the status of the first, second, and third Ethernet links.
RTC Sync Source actual value is the time synchronizing source the relay is using at present. Possible sources are: Port 1 PTP
Clock, Port 2 PTP Clock, Port 3 PTP Clock, IRIG-B, SNTP, and None.
The Grandmaster ID is the grandmasterIdentity code being received from the present PTP grandmaster, if any. When the
relay is not using any PTP grandmaster, this actual value is zero. The grandmasterIdentity code is specified by PTP to be
globally unique, so one can always know which clock is grandmaster in a system with multiple grandmaster-capable
clocks.
Accuracy is the estimated maximum time error at present in the RTC, considering the quality information imbedded in the
received time signal. The value 999,999,999 indicates that the magnitude of the estimated error is one second or more, or
that the error cannot be estimated.
Port 1…3 PTP State is the present state of the port’s PTP clock. The PTP clock state is:
• DISABLED is the port’s function setting is Disabled
• NO SIGNAL if enabled but no signal from an active master has been found and selected
• CALIBRATING if an active master has been selected but lock is not at present established
• SYNCH’D (NO PDELAY) if the port is synchronized, but the peer delay mechanism is non-operational
• SYNCHRONIZED if synchronized
PTP - IRIG-B Delta is the time difference, measured in nanoseconds, between the fractional seconds portion of the time
being received via PTP and that being received via IRIG-B. A positive value indicates that PTP time is fast compared to IRIG-
B time.

The AVERAGE MSG RETURN TIME is the time taken for direct output messages to return to the sender in a direct input/output
ring configuration (this value is not applicable for non-ring configurations). This is a rolling average calculated for the last
ten messages. There are two return times for dual-channel communications modules.
The UNRETURNED MSG COUNT values (one per communications channel) count the direct output messages that do not
make the trip around the communications ring. The CRC FAIL COUNT values (one per communications channel) count the
direct output messages that have been received but fail the CRC check. High values for either of these counts can indicate
on a problem with wiring, the communication channel, or one or more relays. The UNRETURNED MSG COUNT and CRC FAIL
COUNT values can be cleared using the CLEAR DIRECT I/O COUNTERS command.
The DIRECT INPUT 1 to DIRECT INPUT (32) values represent the state of each direct input.
These actual values represent the state of direct devices 1 through 16.
FAST EXCHANGE 1

These values provide information for debugging an EGD network. The EGD signature and packet size for the slow EGD
exchanges display.
CHANNEL 1 STATUS — This represents the receiver status of each channel. If the value is “OK,” teleprotection is enabled and
data is being received from the remote terminal; If the value is “FAIL,” teleprotection enabled and data is not being received
from the remote terminal. If “n/a,” teleprotection is disabled.
CHANNEL 1 LOST PACKETS — Data is transmitted to the remote terminals in data packets at a rate of two packets per cycle.
The number of lost packets represents data packets lost in transmission; this count can be reset to 0 through the
COMMANDS CLEAR RECORDS menu.
VALIDITY OF CHANNEL CONFIGURATION — This value displays the current state of the communications channel identification
check, and hence validity. If a remote relay ID does not match the programmed ID at the local relay, the “FAIL” message
displays. The “N/A” value appears if the local relay ID is set to a default value of “0,” the channel is failed, or if the
teleprotection inputs/outputs are not enabled.
These values specify the remaining number of TCP connections still available for each protocol. The display depends on the
options applicable to your device, for example the PMU entry does not display when not applicable. Each time a
connection is used, the remaining number of connections decrements. When released, the remaining number of
connections increments. If no connection is made over the specific protocol, the number equals the maximum number
available for the specific protocol. 6
For example, the maximum number of Modbus TCP connections is 4. Once an EnerVista session is opened on a computer
connected to the UR over Ethernet, the Modbus TCP status shows 3. If the EnerVista application is closed, the Modbus TCP
status shows 4.
MMS TCP — The number of IEC 61850 connections remaining.
PMU TCP — The maximum number of PMU TCP connections matches the number of aggregators. The maximum number of
aggregators for the N60 is 4. The maximum number for the C60 is 2. The maximum number is 1 for other products with a
PMU. The remaining number of aggregators displays here.
The C30 is provided with optional PRP capability. This feature is specified as a software option at the time
of ordering. See the Order Codes section in chapter 2 for details.
Total Received Port A is a counter for total messages received (either from DANPs or from SANs) on Port A.
Total Received Port B is a counter for total messages received (either from DANPs or from SANs) on Port B.
Total Errors is a counter for total messages received with an error (bad port code, frame length too short).
Mismatches Port A is a counter for total messages received with an error on Port A (PRP frame, but port received through
and LAN ID in the frame do not match).
Mismatches Port B is a counter for total messages received with an error on Port B (PRP frame, but port received through
and LAN ID in the frame do not match).

The timescale of the entered time is local time, including daylight savings time where and when applicable.
This menu contains commands for relay maintenance purposes. Commands for the lamp test and order code are
activated by changing a command setting to “Yes” and pressing the ENTER key. The command setting then automatically
reverts to “No.” The service command is activated by entering a numerical code and pressing the ENTER key.
PERFORM LAMPTEST — Turns on all faceplate LEDs and display pixels for a short duration.
UPDATE ORDER CODE — This command causes the relay to scan the backplane for the hardware modules and update the
order code to match. If an update occurs, the following message displays.
UPDATING...
PLEASE WAIT
There is no impact if there have been no changes to the hardware modules. When an update does not occur, the ORDER
CODE NOT UPDATED message displays.
REBOOT RELAY — Restarts the relay so that changes to configuration settings can take effect. In most cases, if changes are
made to the configuration settings these changes do not take effect unless the relay is rebooted.
With the CyberSentry option, the Administrator or Operator role can initiate the Reboot Relay command.
NOTE
SERVICE COMMAND — Performs specific C30 service actions. Presently, there are two service actions available. Code
"20511" returns all settings to their factory default value. Code “101” is used to clear factory diagnostic information stored
in the non-volatile memory. If a code other than these two is entered, the command is ignored and no action is taken.
Various self-checking diagnostics are performed in the background while the C30 is running, and diagnostic information is
stored on the non-volatile memory from time to time based on the self-checking result. Although the diagnostic
information is cleared before the C30 is shipped from the factory, the user can want to clear the diagnostic information for
themselves under certain circumstances. For example, you clear diagnostic information after replacement of hardware.
Once the diagnostic information is cleared, all self-checking variables are reset to their initial state and diagnostics restart
from scratch.
SAVE VOLATILE DATA — Saves this data to compact flash memory prior to shutdown. This allows the saved data to be as
recent as possible instead of relying on the periodic timer to save the data.

When no targets are active, the display reads NO ACTIVE TARGETS.
If a self test error is detected, a message appears indicating the cause of the error. For example UNIT NOT PROGRAMMED
indicates that the minimal relay settings have not been programmed.
7.2.2.1 Description
The relay performs a number of self-test diagnostic checks to ensure device integrity. The two types of self-tests (major

7 affected field units. This self-test is initiated by low received signal levels at either the Brick or Process Card end, and
by the sustained failure to receive poll responses from the proper Brick.
• Severity: This self-test error does not directly inhibit protection. However, the affected Brick inputs/outputs may not be
available to the UR-series device.
• What to do: Check the field unit actual values. An indication of equipment mismatch means that messages are being
received from a Brick, but there is a discrepancy between the settings and the actual Brick serial number, order code,
and/or core number. Check that the correct core on the correct Brick is patched through to the correct Process Card
port, and that the field unit settings are correct. An indication of communications loss means that no messages are
being received. Check that the patching is correct, and that the Brick has power. If that is not the problem, use a
professional optical fiber connector cleaning kit to clean both sides of all optical fiber connections from the Process
Card through to the affected Brick. If the problem continues after cleaning, consult the factory.
Brick output failing to respond to an output command can only be detected while the command is active, and so in
this case the target is latched. A latched target can be unlatched by pressing the faceplate reset key if the command
has ended, however the output can still be non-functional.

Withdraw or insert a module only when control power has been removed from the unit, and be
WARNING sure to insert only the correct module type into a slot, else personal injury, damage to the unit
or connected equipment, or undesired operation can result.
To avoid damage to the equipment, use proper electrostatic discharge protection (for example, a
NOTICE static strap) when coming in contact with modules while the relay is energized.
The relay, being modular in design, allows for the withdrawal and insertion of modules. Replace modules only with like
modules in their original factory configured slots.
To replace a module:
1. Open the enhanced faceplate to the left once the thumb screw has been removed. This allows for easy access of the
modules for withdrawal. The new wide-angle hinge assembly in the enhanced front panel opens completely and
allows easy access to all modules in the C30.
Figure 8-4: Modules inside relay with front cover open (enhanced faceplate)
842812A1.CDR
The standard faceplate can be opened to the left once the black plastic sliding latch on the right side has been pushed
up, as shown below.
2. With power to the unit off, disconnect individually the connections from the module before removing the module from
the chassis.
3. To properly remove a module, pull simultaneously the ejector/inserter clips, located at the top and bottom of the
module. Record the original location of the module to ensure that the same or replacement module is inserted into the
correct slot. Modules with current input provide automatic shorting of external CT circuits.
To properly insert a module, ensure that the correct module type is inserted into the correct slot position. The ejector/
inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is
smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips
simultaneously. When the clips have locked into position, the module is fully inserted.
8.6 Battery
A battery powers the real time clock on startup of the device.
When required, the battery can be replaced. Because the power supply module contains the battery and there are two
power supply options, two procedures are possible. To determine which procedure to use, check the power supply module
or use the photographs here.
10. Reinstall the battery clip and the metal cover, and reinsert the power supply module into the unit.
11. Power on the unit.
12. Dispose of the old battery as outlined in the next section.
To avoid injury, ensure that the unit has been powered off for a minimum of three minutes
CAUTION before replacing the battery.
Risk of fire if battery is replaced with incorrect type or polarity.
To replace the battery:
1. Turn off the power to the unit.
8 2. Wait a minimum of three minutes to ensure that there is no power to the battery.
3. As outlined in the previous section, open the unit by sliding up the plastic latch on the right side of the front panel
(standard front panel) or unscrewing the panel (enhanced front panel).
4. For the standard front panel, it needs to be removed in order to access the power supply module, which is typically in
the first slot on the left side and blocked by the hinge of the front panel. To remove the front panel, unscrew the bracket
on the front left side of the unit.
5. Simultaneously pull the ejector clips at the top and bottom of the power supply module and remove the module.
6. Unscrew all four screws (not three) that attach the metal cover to the module.
7. Slide the metal cover away from the clips about 1 cm (1/4 inch) and remove the cover.
8. Unclip the black plastic holder that keeps the battery in place. The plastic clips into the socket at the bottom on both
sides. Use a flat-head screwdriver if you cannot unclip the plastic with your fingers.
9. Observe the + and - polarity of the battery and replace it with the same polarity as marked on the battery holder.
Replace the battery with the identical make and model. For example, do not use a rechargeable battery.

10. Reinstall the battery clip and the metal cover, and reinsert the power supply module into the unit.
11. Power on the unit.
12. Dispose of the old battery as outlined in the next section.
You cannot erase directly the flash memory, but all records and settings in that memory can be deleted. Do this using the
SETTINGS PRODUCT SETUP CLEAR RELAY RECORDS command.
8.8 Repairs
The battery and modules inside the case can be replaced without return of the device to the factory. The firmware and
software can be upgraded without return of the device to the factory.
For issues not solved by troubleshooting, the process to return the device to the factory for repair is as follows:
• Contact a GE Digital Energy Technical Support Center. Contact information is found in the first chapter.
• Obtain a Return Materials Authorization (RMA) number from the Technical Support Center.
• Verify that the RMA and Commercial Invoice received have the correct information.
• Tightly pack the unit in a box with bubble wrap, foam material, or styrofoam inserts or packaging peanuts to cushion
the item(s). You may also use double boxing whereby you place the box in a larger box that contains at least 5 cm of
cushioning material.
