1 Welcome

Congratulations on acquiring a Cybectec SMP I/O!

The SMP I/O is a substation-grade distributed input and output (I/O) module designed for today’s
automation systems. It supports analog input, binary input and binary output cards, operates with
AC or DC voltage, and communicates using the DNP3 protocol over serial RS-485, or TCP/IP
using fiber or copper Ethernet. It can be used as a companion to the SMP Gateway, or as a
standalone I/O module.

This document goes through the basic steps required to install and set up the SMP I/O:

‰ Unpacking the SMP I/O and understanding its front and back panels.

‰ Wiring the SMP I/O.

‰ Getting an overview about the principles of operation of the SMP I/O.

‰ Configuring the SMP I/O for use either with or without a Cybectec SMP Gateway.

‰ Adding or removing I/O cards inside the SMP I/O.

Additional reference drawings and a troubleshooting guide are also available at the end of the
manual.

3 Principles of Operation

3.1 System Architecture

The SMP I/O is composed of a base unit (19-inch 1U rack-mountable or 9-inch wall-mountable),
with front panel indicators and controls. It houses the power supply, system processor,
communication interfaces and time synchronization circuits.

Figure 4 Functional architecture

The SMP I/O has 4 slots for field-installable I/O cards. All slots are electrically equivalent. Analog
input cards can only be installed in slots A, B and C. Binary input cards can go into any slots.
Binary output cards can only be installed in lower slots B and D, because of the high-load carrying
capability of the output relays and because they require more vertical clearance. Input and output
cards can be installed simultaneously in a same SMP I/O, and some slots can remain empty.

3.2 Communications Capability

The SMP I/O is provided with both a serial RS-485 interface and an Ethernet interface. Both
interfaces can be used for data communication. The Ethernet interface is also used for the initial
device configuration.

SMP I/O User Manual • 11

 The RS-485 interface is accessed through a rear panel terminal block. It supports 9600 to
115,200 bps communication rate in half-duplex with multidrop capability. Instructions on using
RS-485 to connect the SMP I/O to an SMP Gateway or any other master station are provided in
the “RS-485 Communications Interface” section, page 26.

The SMP I/O also supports TCP/IP communications using the 10/100BASE-TX or optional
100BASE-FX interfaces.

The SMP I/O uses the industry standard DNP3 protocol to communicate with one or two master
stations. It is a level 2 DNP3 device and thus supports report-by-exception for reduced bandwidth
usage. By default, DNP3 communications over Ethernet uses standard port 20000 for main data
communication, and port 20001 for secondary communications, if required. Different port
numbers can be specified at configuration time for both communication links (see “Updating the
Connection Settings”, page 36).

3.2.1 Using the SMP I/O as a Standalone I/O Module

With a standalone SMP I/O, a master station can monitor and control remote devices using the
DNP3 protocol with accurate IRIG-B time-stamping, effectively replacing a traditional RTU.

Multiple SMP I/O devices can be distributed throughout the substation using an RS-485 multidrop
architecture, or using either copper or fiber Ethernet.

3.2.2 Using the SMP I/O with the Cybectec SMP Gateway
The SMP I/O design integrates seamlessly with the Cybectec SMP Gateway.

The Cybectec SMP Gateway, besides acting as a DNP3 master, extends the capabilities of the
SMP I/O by adding the following capabilities:

‰ Device integration using legacy protocols such as Modicon Modbus, Tejas, Cooper 2179, or
new modern protocols such as IEC 61850 and IEC 60870-5-104.

‰ Passthrough access to substation IEDs for maintenance and engineering users.

‰ Local operation support using the Annunciator/HMI option.

‰ Local automation functions capabilities using the built-in logic processor and Soft PLC
module.

‰ Accurate time synchronization using the Cybectec SMP Gateway built-in GPS clock option.

SMP I/O User Manual • 13

 Configuration is simpler, as it is essentially made with the Cybectec SMP Config software for
both the SMP Gateway and the SMP I/O.

3.3 Time Synchronization

The SMP I/O internal clock can be synchronized by an external IRIG-B clock signal, or by the
DNP3 master station.

‰ Synchronization by the DNP3 protocol provides a typical accuracy of ±10 ms.

‰ Synchronization by the demodulated IRIG-B input provides a typical accuracy of ±1 ms.

The SMP I/O supports the following IRIG-B formats:

‰ IEEE 1344.

‰ BCD format with year.

‰ BCD format without year. The DNP3 master station will provide the year. Therefore, you
must enable DNP3 time synchronization. If the master station is an SMP Gateway, see
“General Settings”, page 49; otherwise, see “DNP3 Slave Settings”, page 74.

The SMP I/O does not perform data acquisition until its clock is synchronized, or until 10 seconds
have elapsed. If time synchronization requires more than 10 seconds, data acquisition will start
anyway, but time stamping will show January 1st 2002 until the clock is synchronized.

The SMP I/O does not have an internal real-time clock. The current time is lost whenever the
SMP I/O is powered off or reset. Time is restored, after the following delays, starting at the end of
the SMP I/O initialization sequence:

‰ With an IRIG-B signal, time is typically restored after 2 seconds.

‰ With DNP3 protocol synchronization, the delay depends on the master station implementation
of the protocol. If the SMP I/O is synchronized by a Cybectec SMP Gateway, time is typically
restored after 5 seconds.

If the master station does not resynchronize the SMP I/O time within 5 minutes, time stamping
will show bad quality until the clock is re-synchronized.

3.4 Binary Outputs

The SMP I/O supports up to 18 control relays. The base unit provides two built-in form-C relays
that can be used to report the current system state or control external devices. One or two field-
installable, 8-port binary output cards can also be inserted in slots B and D, in the lower row.

SMP I/O binary outputs are specially designed for the power industry. They provide the following
characteristics:

‰ High-load carrying capability to reduce the need for interposing relays.

14 • SMP I/O User Manual

 ‰ Monitoring of each relay output by an input point that provides the state of a second auxiliary
contact. If the auxiliary contact does not match the requested output state, data quality is
marked as bad and the front-panel LED turns red.

‰ Outputs protection against single component failure. The relay control circuit is designed so
that the failure of a single component cannot accidentally energize the relay.

3.4.1 Supported Output Functions

Each SMP I/O binary output can be configured to provide the following behavior:

‰ Trip/close pair.
A single DNP3 address is used to control two relays. When the master station sends an open
command, the first relay is pulsed. When the master station sends a close command, the
second relay is pulsed. Trip/close relays are paired as follows: 1-2, 3-4, 5-6 and 7-8. The two
built-in relays can also be paired.

‰ Latch.
Energize or de-energize the relay upon reception of a master station command.

‰ Pulse.
Energize the relay for a specified duration. The duration can be preset or provided by the
master station.

‰ Pulse to open and pulse to close (pulse pair).

The master station uses two separate DNP3 addresses to control the relay. The master station
pulses one address to energize the relay, and a different address to de-energize the relay.

3.4.2 Monitoring Outputs

The current state of each binary output is monitored by an associated binary input. In case of a
malfunction, the quality of this input will be set to bad and the front panel's corresponding LED
will turn to red.

3.4.3 Built-in Outputs

The base unit provides two built-in Form C relays accessible through a terminal block on the back
panel. Each relay has a normally closed (NC) and a normally open (NO) contact.

Figure 7 Back panel terminal block for built-in form C relays

SMP I/O User Manual • 15

 The two relays can be used to control external devices or to indicate system behavior. The relays
can be configured to perform one of the following functions:

‰ Normal.
The relay is controlled by the master station to perform one of the behaviors explained in the
“Supported Output Functions” section, page 15.

‰ Watchdog.
The relay is energized when the power is on and the SMP I/O is performing data acquisition
normally; it de-energizes otherwise.

‰ Remote/Local.
The relay energizes if the L/R button is pushed to put the SMP I/O in local mode. This is also
indicated by the front-panel Local LED turning red. The relay de-energizes if the SMP I/O is
in standard remote mode.

3.4.4 Binary Output Cards

SMP I/O binary output cards provide 8 normally open (NO) relay contacts. Because of the
physical clearance required, binary output cards can only be inserted into slots B and D of the
SMP I/O.

Figure 8 8-port binary output card

3.4.5 Local/Remote Operation Modes

The SMP I/O normally runs in the remote operation mode, which means that it can receive control
commands from a remote master station. When switched to local operation mode, all received
control commands are ignored. This is used as a safety measure for maintenance purposes.

‰ To switch to local mode, hold down the front panel’s Local/Remote button for at least
5 seconds.

‰ To toggle back to remote mode, press the button again for at least 5 seconds.

‰ You can disable the Local/Remote button using SMP I/O Manager. For more details, see
“Disabling the Local/Remote Button on the SMP I/O”, page 40.

16 • SMP I/O User Manual

3.5 Binary Inputs
The SMP I/O supports up to 4 binary input cards with 8 electrically-independent inputs per card.
Binary inputs are available for all commonly-used voltage ranges. Cards used for different voltage
ranges can be installed in the same unit.

3.5.1 Voltage Ranges

Many common opto-isolated input circuits do not implement any form of hysteresis and can give
spurious input transitions as the wetting voltage and thresholds vary with temperature. The
SMP I/O input circuitry is specially designed to ensure at least 10% hysteresis at all temperatures,
ensuring wetting voltage noise immunity over the complete temperature range.

Figure 9 shows the effect of hysteresis on the threshold levels.

3.5.2 Input Filtering

when reading status changes. Tolerance and intolerance filters are provided, as well as polarity
inversion for negative-going impulses.

TOLERANCE INTOLERANCE

TIME TAG AVAILABLE

Figure 10 Input debouncing

The input debouncing circuit operates in the following manner:

‰ As soon as the input exceeds the ON threshold, the transition is recorded and the tolerance
delay begins.

‰ Any transition occurring during the tolerance period is ignored.

‰ The intolerance period begins immediately after the end of the tolerance period. Any
transition occurring during this period cancels the operation and resets the filtering process:
the transition is then ignored.

‰ At the end of the intolerance level, the data becomes available. The data is recorded with the
time of the initial transition.

3.5.3 Monitoring Inputs

Each binary input is mapped to three DNP3 data points, providing the following information:

18 • SMP I/O User Manual

 ‰ The current state of the input.

‰ A count of transitions on the same input.

‰ A frozen count of the transitions on the same input.

Transition counters for all inputs can be frozen, reset, or frozen and reset by a single operation.
Counter values are stored in non-volatile memory, which means they persist when the SMP I/O
resets or when it is powered off.

Note: If the SMP I/O communicates with two different master stations, operations on
transition counters are reflected on both communication links. For example, if the
primary master station freezes a given transition counter, the same counter will
also appear to the secondary master station as frozen.

3.5.4 Binary Input Cards

SMP I/O binary input cards provide 8 electrically independent, optically coupled inputs.

3.5.4.1 Error Detection Circuit

An optional error detection circuit (EDC) adds a second independent circuit for each input. If a
discrepancy between both circuits is detected, the corresponding front-panel status LED turns red
(see "Front Panel”, page 4) and the input quality is marked as bad.

3.6 Analog Inputs

The SMP I/O supports up to 3 analog input cards with 8 isolated inputs per card. The standard
model of analog input card can be inserted in slots A, B and C, but not in slot D; the high isolation
model can only be inserted in slots A and C. Binary input cards or binary output cards can be
installed in the remaining slots.

Analog input cards have the following characteristics:

‰ They are designed for DC value measurements only. Each card is equipped with a Delta-
Sigma 16 bits Analog-to-Digital Converter (ADC) for each channel, ensuring high accuracy
reading.

SMP I/O User Manual • 19

 ‰ Can be used both for voltage and current inputs (see “Input Types”, below).

‰ Each input channel provides 2100 VDC or 1500 VAC channel-to-ground dielectric isolation.

A high isolation model (HIM) of the card is available, on which each channel is electrically
independent, providing 2100 VDC or 1500 VAC channel-to-channel isolation. Except for this
isolation characteristic, and the fact that it can only be inserted in slots A and C, the HIM
analog input card has the same characteristics and functionalities.

‰ Each card is factory-calibrated, ensuring high input precision of ±0.02% at 25 °C, with a drift
of only ±0.0015% / °C (for voltage input).

3.6.1 Input Types

Each input of the analog input card can be used either for voltage or current input:

‰ For voltage input, the range is -10V to 10V. The input impedance is over 10 Mohms.

‰ For current input, an alternate circuit with a 2.5 kohms high-precision resistor is selectable,
resulting in an input range of -4mA to 4mA. This circuit is ideal for 0 to 1mA transducers,
with very good over-range capabilities.

Note: To use a current transducer with a different input range (4 to 20 mA, for
example), the analog input must be configured for voltage input, and external
scaling resistors must be installed. .

Here are the recommended specifications for external scaling resistors:

Value: 249 Ω
Power Rate: 0.5 W
Tolerance: 0.1%
TCR: ± 10 ppm/°K

To configure the type of an input:

‰ The input jumper must be installed on the appropriate pins on the card. For more details, refer
to “Analog Input Wiring”, page 29.

‰ The input type must be specified at configuration time, using either SMP Config or
SMP I/O Manager. Refer to “Configuration with an SMP Gateway”, page 45, or
“Configuration without an SMP Gateway”, page 71.

3.6.2 Monitoring Inputs

Each analog input is mapped to seven DNP3 data points, providing the following information:

‰ The current value of the input, as an analog input data point.

‰ Warning and alarm thresholds (high and low). These 4 system binary input data points
become active when the input level reaches one of these thresholds.

20 • SMP I/O User Manual

 ‰ The minimum and maximum values reached for this input since last system restart, as system
analog input data points.

Minimum and maximum system data points can be reset to 0 by performing a pulse command
operation on the All_Analog_Min_Max_Reset system binary output point.

3.6.3 Analog Input Cards

3.7 Event Reporting

Events reports are sent to the master station on request, or by exception when unsolicited reports
are enabled. Unsolicited reporting rules are defined by the Class 1-2-3 Report Min Event and
Class 1-2-3 Report Delay settings. For more details about these settings, see “DNP3 Slave
Settings”, page 74.

3.7.1 Event Queue

Between event reports, events of all data point types are stored in a single queue. Binary inputs are
stored as sequences of events (SOE): all transitions are stored until next report transmission, as
long as there is enough space in the queue. For data points of other types, only the most recent
value is stored. Space is not an issue for these types of points, as only one transition per point is
kept.

Only data points configured with an event class different than 0 are stored in the queue. The size
of the queue is function of the space available as well as the number of data points configured with
an event class of 1, 2 or 3. Sufficient memory space is allocated to store one (the most recent)
transition of non-binary inputs. The remainder of the space is allocated for binary input transitions.
For example, if all binary inputs are configured with an event class of 1, and all other points are
configured with an event class of 0, the queue may hold up to 700 binary input events.

Note: If the SMP I/O is configured to run two DNP3 slaves, there is one event queue for
each slave instance. However, as less memory is available, each queue can only
hold up to 250 binary input events, if only binary inputs are configured with an
event class different from 0.

SMP I/O User Manual • 21

 If the event queue is full and a new binary input event occurs, this new event will be discarded so
that only the oldest events are kept in the queue.

4 Installation

Two different SMP I/O base units are available: one can be mounted in a standard 19-inch rack
and another that can be installed on the surface of a wall. The wall-mountable SMP I/O is
designed to be installed in many ways, depending on the side of the unit that is fixed to the wall.
The same I/O cards can be installed on both base units.

This chapter describes how to install the SMP I/O base unit, and connect it to a power supply, to
the master station and to input and output signals.

Note: Except when mentioned, the figures that appear in this section depict parts of a
rack-mountable SMP I/O. However, the connectors are arranged in a very similar
manner on the back panel of a wall-mountable SMP I/O.

4.1 Rack-Mounting the SMP I/O

The rack-mountable SMP I/O is designed to be installed in a standard 19-inch rack, occupying 1U.

To protect against accidental damage during transport, the mounting brackets are not installed at
the factory.

To install the mounting brackets:

‰ Locate the two brackets provided with the SMP I/O packaging, as well as the 8 Phillips flat
head screws.

‰ Screw the brackets on each side of the device, as illustrated on the dimension drawings
provided at the end of this document (see page 114).

To install the SMP I/O in the rack:

‰ Bolt the device to the vertical railing using four rack screws (not provided) through the two
holes on the front side of each bracket.

SMP I/O User Manual • 23

4.2 Wall-Mounting the SMP I/O
The wall-mountable SMP I/O is designed to be installed on the surface of a wall. The mounting
brackets can be installed in different manners and the bracket arms have different lengths,
allowing the mounting of the unit in any virtually possible position, even in narrow spaces.

To protect against accidental damage during transport, the mounting brackets are not installed at
the factory.

To install the mounting brackets:

‰ Locate the two brackets provided with the SMP I/O packaging, as well as the 8 Phillips flat
head screws.

‰ Referring to the dimension drawings of the wall-mountable SMP I/O that are provided at the
end of this manual (see page 114), determine where and how to install the brackets on the
base unit.

‰ Screw the brackets on the base unit accordingly.

The installation of the unit on the wall is left to the discretion of the installer.

4.3 Back Panel Connections

The SMP I/O is designed to be easy to set up and to maintain. All wiring is connected through
removable connectors, allowing you to remove the device from the rack without needing to
remove any cable, reducing the chance of error. Moreover, all connectors are keyed to prevent
accidental insertions that would damage the I/O module or its peripherals.

Note: You will need a flat blade screwdriver for M2.5 screws, used to remove and
install the connectors, and grip the wires.

4.3.1 Power Supply Wiring

Connect the SMP I/O power supply to the power source using the provided cable, and the terminal
block and ground lug identified in Figure 13.

Figure 13 Power supply terminal block and ground lug location

24 • SMP I/O User Manual

 Note: On the wall-mountable version of the SMP I/O, the power supply terminal block is
located at the same place, above the Ethernet and IRIG/485 connectors.
However, it has two terminals instead of four.

‰ For a low voltage power source, use terminal 1 for the positive wire and terminal 2 for the
negative wire. Connect the earth ground to the ground lug as shown in the following figure.

The type of each input can be set for voltage or current input using the jumper located at the back
end side of the card. A jumper in the “I” position (left position when looking from the rear) means
current input and a jumper in the “V” position (right position when looking from the rear) means
voltage input. The “I” and “V” letters are printed on the card board, on each side of the jumper
pins.

Analog input cards are shipped with all inputs configured for voltage input.

Note: There is a separate jumper for each input of the card.

Also for each input of the card, the input type must be specified at configuration
time, using either SMP Config or SMP I/O Manager. Refer to “Configuration with
an SMP Gateway”, page 45, or “Configuration without an SMP Gateway”,
page 71.

‰ Load the self-running CD in your computer.

‰ Follow the on-screen instructions.

The installation program adds the following to Windows’ Start menu:

SMP I/O User Manual • 31

 Figure 28 SMP IO Windows Start menu items

If you have Cybectec SMP Tools installed, the installation program also adds the SMP I/O
Manager command to the Tools menu of SMP Manager.

4.5.1 Starting SMP I/O Manager

To start SMP I/O Manager:

‰ From the Start menu on the Windows taskbar, click All Programs, then Cybectec, then
SMP IO, and select SMP IO Manager.

Figure 29 SMP I/O Manager

You can also start SMP I/O Manager from SMP Manager:

‰ In SMP Manager, from the Tools menu, click SMP I/O Manager.

32 • SMP I/O User Manual

5 Configuration Overview

Configuring an SMP I/O requires a slightly different approach than configuring a Cybectec SMP
Gateway. To configure an SMP Gateway, you connect a cable to the console port of the gateway,
reset the device and enter configuration mode where special commands are available to set the
network address. Eventually, you must create a configuration file that must be sent to the gateway.

For the SMP I/O, you connect the device to your network and start SMP I/O Manager. The
application automatically locates all SMP I/O devices connected to all the network segments the
PC is connected to, and adds each SMP I/O, with its IP address and name (if available), to the list
of known SMP I/Os. You then select the appropriate SMP I/O from the list and perform the
following configuration steps:

‰ Enter an IP address and the network settings. SMP I/O Manager uses the UDP/IP protocol to
communicate with the SMP I/O. You must thus provide a different static IP address for each
device.

‰ Enter the DNP3 connection settings: set up the primary and secondary communication links
using serial or TCP/IP, and configure the built-in firewall.

‰ Update the firmware, if required (see “Updating the Firmware”, page 41).

The next steps depend on how you intend to use the SMP I/O.

To use the SMP I/O with the Cybectec SMP Gateway:

‰ Prevent further modifications to the connection settings by locking them (see “Locking the
SMP I/O Settings”, page 42).

‰ Use SMP Config to configure the input and output data points and upload this configuration
to the SMP Gateway. Restart the SMP Gateway and it will upload the new settings to the
SMP I/O automatically (see “Configuring the SMP I/O in SMP Config”, page 48, for more
details).

To use the SMP I/O without a Cybectec SMP Gateway:

‰ Edit the standalone settings. These include the configuration of input processing and output
operations, and some DNP3-specific parameters (see “Configuration without an
SMP Gateway, page 71).

SMP I/O User Manual • 33

 ‰ Prevent further modifications to the connection and standalone settings by locking them (see
“Locking the SMP I/O Settings”, page 42).

Once it is configured, the SMP I/O does not necessarily need to be connected to the network via
the Ethernet port: DNP3 data can be exchanged using the RS-485 serial link, if Ethernet is not the
preferred communication link.

6 Basic Configuration

6.1 Setting the SMP I/O IP Address

In order to configure your SMP I/O you need to provide it with a unique IP address.

‰ In SMP I/O Manager, select the SMP I/O you wish to configure.

‰ Click the SMP I/O button on the lower-left corner of the window.

‰ Click Change IP Address to display the following dialog box:

Figure 30 SMP I/O Manager Change IP Address dialog box

Parameter Description

IP Address The IP address of the SMP I/O.

7 Configuration with an SMP
Gateway

In this section we will discuss the necessary steps to configure the SMP Gateway as a master
station, to poll the SMP I/O and to process the exchange of data to and from a master station.

Note: SMP I/O Manager includes configuration functions that allow you to use the
SMP I/O without the SMP Gateway. For more details, refer to the “Configuration
without an SMP Gateway” section, page 71.

The configuration process is greatly simplified when the SMP I/O is used with the SMP Gateway.
The Add New SMP I/O Instance wizard in SMP Config connects to the SMP I/O and
automatically retrieves the device configuration. The wizard then automatically creates the master
protocol instance and communication component necessary to support the SMP I/O. The only
configuration work remaining is to set up the mode of operation for outputs and the input
processing functions.

Note that while the SMP I/O uses the DNP3 protocol to communicate with a master station, all of
its settings are configured under the SMP I/O branch in SMP Config.

7.1 Using SMP Config’s Add SMP I/O Instance

Wizard
The Master menu in SMP Config provides access to the configuration wizard that you will use to
help you through the different steps required to connect the SMP I/O to the SMP Gateway.

 ‰ For serial communications, you need to know which port of the SMP Gateway will be
used, the interface type that port uses to communicate, its speed in bits per second as well
as parity and stop bits. The settings must be the same that were used while setting up the
SMP I/O serial communication link.

‰ When network communication parameters are set, click Next to specify the SMP I/O
configuration.

‰ In the Device prefix text box, type a string that will be added to the name of all data
points. The device prefix ensures that all data point names are unique, even when
connecting to multiple devices with the same configuration.

‰ When you click Finish, SMP Config will create a new branch under SMP I/O in the
Master Protocols branch. The wizard will also create a new branch under the
Connections branch and will map it to the SMP I/O instance in the Connection Usage
branch.

‰ You can also use the wizard to change the settings, with the Modify Instance command,
or to remove an SMP I/O, with the Remove Instance command.

Note: There is a similar wizard to modify an existing SMP I/O instance configuration.
From the Master menu, click Modify SMP I/O Instance.

Next section explains how to configure the SMP I/O instance and to complete the SMP I/O
configuration.

7.2 Configuring the SMP I/O in SMP Config

Once you have created the SMP I/O instance using the wizard, you will need to specify the mode
of operation of the binary outputs and the processing of the analog and binary inputs.

While the SMP I/O uses the DNP3 protocol, most of the complexities of the protocol have been
hidden. As you will see, many DNP3 settings are not available under the SMP I/O branch in
SMP Config.

48 • SMP I/O User Manual

 Communication between the SMP I/O and the SMP Gateway has the following characteristics:

‰ All analog inputs are configured as Class 2 data.

‰ All binary inputs are configured as Class 1 data.

Class 0123 Poll Cycle Time interval, in milliseconds, after which the SMP Gateway will send a
read request for Class 0, Class 1, Class 2 and Class 3 data (static I/O point
value and change event).

By default, Class 0 data is polled once every hour. As all counters are
stored as Class 0, you may want to increase the polling rate.

SMP I/O User Manual • 49

 Parameter Description

Class 123 Poll Cycle Time interval, in milliseconds, after which the SMP Gateway will send a
read request for Class 1, Class 2 and Class 3 data (report by

By default, this value is set to 1 second.

Clock Sync A checkmark indicates that the SMP Gateway will synchronize the
SMP I/O using the DNP3 protocol.

Clock Sync Cycle Time interval, in milliseconds, after which the SMP Gateway master will
send a clock synchronization request to the SMP I/O, if allowed (see the
Clock Sync setting, above).

By default, this value is set to 30 seconds.

Unsolicited Report Select this checkbox to enable unsolicited reporting.

You should not enable unsolicited reporting if you intend to use RS-485 to
connect with multiple devices using a multidrop link.

Selection Timeout The number of milliseconds during which an execution control request can
be issued after an output point was successfully selected. If the timeout
period expires, the execution control request is refused.

A value of 0 disables selection timeout.

By default, this value is set to 5 seconds.

Delay Between Tx Indicates the minimum delay, in milliseconds, between 2 consecutive

transmissions.

By default, this value is set to 0.

Notify When Ready Put a checkmark to activate the “initial general interrogation completed”
notification mechanism.

This mechanism allows SMP Gateway slave components (those configured

to do so) to wait before allowing connections from a master station, until
either the SMP I/O master component completes its first general
interrogation or until there is a timeout, if the communication cannot be
established. This way, after an SMP Gateway reboots, the master station
does not see any useless transitions resulting from system initialization.

By default, this value is not set.

Hot Standby Support Put a checkmark to enable the “Hot Standby” SMP Gateway redundancy
feature. This setting applies only when 2 SMP Gateways are grouped
together in a redundant configuration.

7.2.4 Binary Input Cards

For each I/O card in the SMP I/O, the wizard creates a branch that contains all the data points
supported by the card.

For binary input cards, you will see the following branches:

‰ Analog Inputs.
This branch defines data points that contain the card serial number, revision number, and the
model number.

‰ Binary Inputs.
This branch defines data points that represent the state of each of the 8 input points of the
card.

‰ Counter Inputs.
This branch defines data points used to count the number of times each input changed state.

‰ Frozen Counter Inputs.

This branch contains the value of the counter inputs when the Freeze Counter request is
processed.

The address of each data point of the card depends on the card position. An offset is added to the
address to ensure that each data point has a unique address.

‰ For a card in slot A, add 100 to the data point address.

‰ For a card in slot B, add 200 to the data point address.

‰ For a card in slot C, add 300 to the data point address.

‰ For a card in slot D, add 400 to the data point address.

All data points in the SMP Gateway must also have a unique name. The wizard builds the data
point name by adding the slot identifier to the default point name. In this manner, the first binary
input of a card located in slot C will be identified “C1_Input_State”, with a DNP3 address of 300.
The name of each physical data point can be modified by the user.

7.2.6 Analog Input Cards

For each I/O card in the SMP I/O, the wizard creates a branch that contains all the data points
supported by the card.

For analog input cards, you will see the following branches:

‰ Analog Inputs.
This branch specifies the type (current or voltage) of each analog input of this card. It also
defines the physical analog input data points themselves, and the internal (system) data points
such as the serial number and revision number of the card, as well as minimum and maximum
values for each input.

‰ Binary Inputs.
This branch defines two warning data points and two alarm data points for each analog input.

The address of each data point of the card depends on the card position. An offset is added to the
address to ensure that all data points have a unique address.

‰ For a card in slot A, add 100 to the data point address.

‰ For a card in slot B, add 200 to the data point address.

settings can be specified in the Standalone Settings dialog box, under either the branch DNP3
Slave 1 or DNP3 Slave 2 (see “Overview”, page 71).

Figure 44 DNP3 slave settings

Each slave/link must be configured separately. The DNP3 Slave 2 branch is only visible if the
secondary communication link was activated in the connection settings (see “Updating the

74 • SMP I/O User Manual

 Connection Settings”, page 36).

Parameter Description

Name The name of the SMP I/O, as displayed in SMP I/O Manager.
(DNP3 Slave 1 only)

Inactivity timeout The number of seconds that the slave will wait after the last valid data link
layer frame is received, before resetting the communication link.

This setting is only used with a TCP/IP communication link.

By default, it is set to 5 seconds.

DNP3 Time Select this checkbox to allow the reception of time synchronization
Synchronization requests from the master station.

If both DNP3 slaves are configured, only one should be responsible for
time synchronization.

Need Time Delay The number of milliseconds to which the “need time” Internal Indication
(IIN) (contained in every application response message) must be set for the
master station to write time back to the device.

A value of 0 means that the SMP I/O will never request time
synchronization from the master station.

If the SMP I/O is not connected to any IRIG-B source, this delay must be
smaller than 300,000 milliseconds (5 minutes). Otherwise, the master
station may eventually receive events with bad quality timestamps.

By default, it is set to 30,000 milliseconds.

Unsolicited report Select this checkbox to enable unsolicited reporting.

It is not recommended to enable unsolicited reporting if you intend to use

RS-485 to connect with multiple devices using a multidrop link.

Unsolicited Retry Delay If an unsolicited response is not confirmed within the application
confirmation timeout, this setting controls how soon, in milliseconds,
another unsolicited response will be sent.

If this setting is 0 or less than the application confirmation timeout, the

unsolicited report will be sent again as soon as the application confirmation
timeout expires (unless a read request was received in the meantime, in
which case the read request will first be responded to).

By default, this value is set to 0 milliseconds.

Unsolicited Infinite Select this checkbox to retry the transmission of unsolicited reports an
Retries infinite number of times or until the reception of an application
confirmation from the master station.

SMP I/O User Manual • 75

 Parameter Description

Unsolicited Max Retries The number of attempts to re-transmit an unsolicited report without getting
a confirmation from the master station.

This parameter is ignored if the Unsolicited Infinite Retries parameter is

checked.

By default, this value is set to 2.

Class 1 Report Min For class 1 events, this setting controls the conditions under which an
Event unsolicited response will be sent. If the number of events in this class
matches or exceeds this value, an unsolicited response will be sent.

This setting is used in conjunction with the Class 1 Report Delay setting,
as the unsolicited response is sent as soon as either one of the two
conditions is met. The Class 1 Report Min Event setting is ignored if the
Class 1 Report Delay parameter value is set to 0 milliseconds.

This value ranges between 0 and 255. By default, it is set to 10.

Class 2 Report Min For class 2 events, this setting controls the conditions under which an
Event unsolicited response will be sent. If the number of events in this class
matches or exceeds this value, an unsolicited response will be sent.

This setting is used in conjunction with the Class 2 Report Delay setting,
as the unsolicited response is sent as soon as either one of the two
conditions is met. The Class 2 Report Min Event setting is ignored if the
Class 2 Report Delay parameter value is set to 0 milliseconds.

This value ranges between 0 and 255. By default, it is set to 10.

Class 3 Report Min For class 3 events, this setting controls the conditions under which an
Event unsolicited response will be sent. If the number of events in this class
matches or exceeds this value, an unsolicited response will be sent.

This setting is used in conjunction with the Class 3 Report Delay setting,
as the unsolicited response is sent as soon as either one of the two
conditions is met. The Class 3 Report Min Event setting is ignored if the
Class 3 Report Delay parameter value is set to 0 milliseconds.

This value ranges between 0 and 255. By default, it is set to 10.

Class 1 Report Delay For class 1 events, this setting can be used to control the conditions under
which an unsolicited response is sent. If the time after an event occurs
matches or exceeds this value in milliseconds, even if only one event has
occurred, an unsolicited response will be sent.

This setting is used in conjunction with the Class 1 Report Min Event
setting, as the unsolicited response is sent as soon as either one of the two
conditions is met. If the Class 1 Report Delay parameter value is set to 0,
the Class 1 Report Min Event parameter is ignored and an unsolicited
response will be sent as soon an event of this class occurs.

By default, this value is set to 500 milliseconds.

76 • SMP I/O User Manual

 Parameter Description

Class 2 Report Delay For class 2 events, this setting can be used to control the conditions under
which an unsolicited response is sent. If the time after an event occurs
matches or exceeds this value in milliseconds, even if only one event has
occurred, an unsolicited response will be sent.

This setting is used in conjunction with the Class 2 Report Min Event
setting, as the unsolicited response is sent as soon as either one of the two
conditions is met. If the Class 2 Report Delay parameter value is set to 0,
the Class 2 Report Min Event parameter is ignored and an unsolicited
response will be sent as soon an event of this class occurs.

By default, this value is set to 500 milliseconds.

Class 3 Report Delay For class 1 events, this setting can be used to control the conditions under
which an unsolicited response is sent. If the time after an event occurs
matches or exceeds this value in milliseconds, even if only one event has
occurred, an unsolicited response will be sent.

This setting is used in conjunction with the Class 3 Report Min Event
setting, as the unsolicited response is sent as soon as either one of the two
conditions is met. If the Class 3 Report Delay parameter value is set to 0,
the Class 3 Report Min Event parameter is ignored and an unsolicited
response will be sent as soon an event of this class occurs.

By default, this value is set to 500 milliseconds.

Link Confirmation Indicates under which circumstances the SMP I/O should request a link
layer confirmation from the master station.

Allowed values: Never Not for any frame

Sometimes For multi-frame fragments only
Always For all frames

By default, the selected mode is “Never”, as recommended by the DNP

Technical Committee: the Application Confirmation Timeout setting
should be used instead.

Data link confirm should be disabled when communicating on a TCP/IP

link.

Link Confirmation The number of milliseconds to wait for the master station data link layer
Timeout confirmation of the last frame sent before attempting any retries (only if
the frame is sent with confirm requested). It is measured after the last byte
of the data frame is sent.

A value of 0 causes an immediate timeout.

By default, the value is set to 1,500 milliseconds.

Link Max Retries The number of attempts made to re-transmit a data link frame that was not
confirmed by the master station (only if the frame is sent with confirm
requested).

This value ranges between 0 and 255. By default, it is set to 2.

SMP I/O User Manual • 77

 Parameter Description

Application The number of milliseconds to wait for the master station to confirm the
Confirmation Timeout previous response, if requested.

If application layer confirmations are used with data link confirmations,

make sure the application layer confirmation timeout is long enough for all
data link retries to complete. The following formula describes this
requirement:

Application Confirmation Timeout >

Link Confirmation Timeout * (Link Max Retries + 1)

By default, the value is set to 3,500 milliseconds.

Selection Timeout The number of milliseconds following a select command, during which an
operate command must be received before the selection times out.

A 0 value will cause an immediate timeout.

This value ranges between 0 and 3,600,000. By default, it is set to 10,000

milliseconds.

9.1 Using the SMP Gateway’s Built-in Web Server

to Simplify System Commissioning
The SMP I/O is designed to integrate seamlessly with the SMP Gateway. When using the
Cybectec SMP Gateway, you gain access to its extensive communications capabilities, multiple
universal RS-232/422/485 serial ports, optional built-in GPS clock, all commonly used SCADA
protocols and a built-in web server.

The SMP Gateway’s web server is a great application to view device data and test your system
engineering. The web server displays the current value of all points processed by the
SMP Gateway, including all I/O points provided by the SMP I/O. You can also use the web
interface to view system logs and statistics.

With the Commissioning Tool function, you can use the web interface to test all data paths from
the device to the control center, and the control center to the device.

10 Inserting and Removing I/O
Cards

The SMP I/O is designed to be easily field-upgradeable and allows the addition of new I/O cards
as project requirements evolve.

10.1 Installation Procedure

The installation procedure is simple, but care must be exercised to prevent the accidental damage
caused by static electricity.

‰ Make sure the SMP I/O is powered off.

‰ Remove any plastic, vinyl or foam from the work area.

‰ Discharge any static electricity by touching a ground surface.

‰ Wear an antistatic wrist strap.

‰ Handle the expansion card only by its edges, and avoid touching the circuitry.

‰ Do not slide the expansion card over any surface.

‰ Limit body movement (which builds up static electricity) during installation.

‰ Proceed as follows for each expansion card to be installed:

‰ Remove the back plate and its 3 screws using a Phillips #2 screwdriver.

SMP I/O User Manual • 105

 Figure 66 Removing the back plate of a rack-mountable SMP I/O

Note: The back plate of the wall-mountable version of the SMP I/O base unit can be
removed in a similar manner.

‰ Remove the plate hiding the specific card connector slot.

‰ If the card is an analog input card, make sure each input’s jumper is installed according to
the input type required. For more details, see “Analog Input Wiring”, page 29.

Note: Analog input card support requires version 2.0 or later of the firmware to be
installed on the SMP I/O.

‰ Insert the expansion card in the desired slot, making sure to push the card all the way in
so that it plugs into the connector at the back.

Note: Remember that binary output cards can only be inserted in slots B and D;
standard analog input cards, in slot A, B and C; high isolation analog input cards,
in slot A and C; and binary input cards, in all slots (A to D).

Moreover, binary output cards require much vertical clearance for insertion than
other types of cards. Therefore, to insert a binary output card, you must first
remove any card install in the slot above, and reinsert this card afterwards.

‰ Put the back plate back and fasten it with its 3 screws.

‰ Update the SMP I/O software configuration accordingly using SMP I/O Manager (see “I/O
Cards Settings”, page 86) or SMP Config (see “Binary Input Cards”, page 56, or “Binary
Output Cards”, page 60).

10.2 Removing an Expansion Card

To remove an expansion card:

106 • SMP I/O User Manual

 ‰ Remove the 3 screws holding the back plate.

‰ Remove the card by pulling on the green connector. If access is difficult, use long nose pliers
and gently pull, this should not be difficult. Do not pinch the blue capacitors behind the green
connector, it could damage the card.

‰ Place the back plate back on and fasten it with its 3 screws.

‰ Update the SMP I/O software configuration accordingly using SMP I/O Manager (see “I/O
Cards Settings”, page 86) or SMP Config (see “Binary Input Cards”, page 56, or “Binary
Output Cards”, page 60).

SMP I/O User Manual • 107

11 Troubleshooting

The SMP I/O is a highly reliable substation-grade device. Most operational problems result from
configuration errors, and there are a few simple steps you can take to solve these problems.

This chapter discusses the following types of problems:

‰ Configuration problems

‰ Communication problems.

‰ Problems with data validity.

‰ Problems executing control operations.

11.1 Safe Mode

The Safe mode is a special operational mode that allows fast recovery of an SMP I/O that was
updated with corrupted settings or parameters files that are incompatible with the current firmware
application version that is running on the unit. In this mode, the firmware application is running,
but the protocol components are not active, which means that SMP I/O Manager can still be used
to update the SMP I/O’s connection and standalone settings.

Note: The SMP I/O may also fall automatically into Safe mode at startup, if the
initialization of a protocol component fails,

To Force an SMP I/O into Safe Mode:

‰ Power off the SMP I/O and power it on again

‰ During the startup sequence, press and hold the L/R button until the ST LED turns to red.

The SMP I/O will then be in Safe mode.

The SMP I/O is now available for SMP I/O Manager usual operations, but not for DNP3
communications. It will remain in this state until the SMP I/O’s next reboot.

108 • SMP I/O User Manual

11.2 Rescue Mode
If the SMP I/O is not responsive or is continuously rebooting, the firmware application and/or
current settings might be corrupted. The solution is to force the SMP I/O is Rescue mode, and then
to reload the firmware application.

When the SMP I/O is in Rescue mode, two user operations are allowed:

‰ The manual upload of a file to the SMP I/O.

‰ The reset of the SMP I/O’s IP address to a default factory address.

11.2.1 Forcing the SMP I/O into Rescue Mode

To force an SMP I/O into Rescue mode, it must be physically accessible.

‰ Power off the SMP I/O, and then power it on again.

‰ During the startup sequence (which lasts about 5 seconds), press the front panel SELECT
button once.

The ST LED will start blinking green, and the SMP I/O will be in Rescue mode for a minute,
after which it will reboot.

11.2.2 Manually Uploading a File to the SMP I/O

Is it possible to force the SMP I/O into Rescue mode, and then upload a file to it using SMP I/O
Manager’s Update Firmware function or using any other TFTP client.

When the SMP I/O is in Rescue mode, it is ready to receive a bootstrap program file, a firmware
application file or a parameters file. Any other file will be rejected by the SMP I/O’s bootstrap
program. The SMP I/O supports the Trivial File Transfer Protocol (TFTP), so any TFTP client
application can be used for the upload. The following procedure uses SMP I/O Manager’s Update
Firmware function.

Note: This upload method should only be used in emergency situations, or when
recommended by Cooper Power Systems’ technical assistance team.

‰ For the SMP I/O into Rescue mode, as described above.

Once the SMP I/O enters this mode, you have one minute to initiate the file transfer.

‰ In SMP I/O Manager, select the SMP I/O, click the SMP I/O button and then click Update
Firmware. Quickly select the file to upload and click Open.

Note: Any other TFTP client can also be used to transfer the file. Use the SMP I/O’s IP
address for the destination’s address and UDP port number 69 (this is TFTP’s
default UDP port).

SMP I/O User Manual • 109

 The SMP I/O will reboot as soon as the transfer will be completed.

11.2.3 Resetting the SMP I/O’s IP Address to Default

If the IP address of an SMP I/O has been forgotten and the SMP I/O is no longer accessible using
SMP I/O Manager, it is possible to reset it to a default factory address. The SMP I/O must be
physically accessible.

Note: The SMP I/O’s default factory IP address is 172.22.100.1.

‰ Restart the SMP I/O in Rescue mode, as described above.

‰ While the SMP I/O is in Rescue mode, press and hold the L/R button located on the front
panel for 5 seconds.

The LOCAL LED will start blinking orange and the SMP I/O will reboot. The LOCAL LED
will continue to blink until the SMP I/O completes its startup sequence.

Until a new IP address is assigned to the SMP I/O, the LOCAL LED will always blink orange
during the startup sequence.

11.3 Configuration Problems

Here are the most frequent configuration problems and some suggested solutions:

‰ The SMP I/O refuses new settings updated via SMP I/O Manager:

‰ Settings are probably locked. To learn how to lock and unlock the settings, see “Locking
the SMP I/O Settings”, page 42.

‰ The SMP I/O may be powered off or resetting. Make sure that a power supply is
connected and that the SMP I/O is started. The ST LED on the front panel should be
green.

‰ In the Standalone Settings dialog box of SMP I/O Manager, only the DNP3 Slave 1 (the
primary data communication link) branch appears. How can I configure DNP3 Slave 2 (the
secondary data communication link)?

‰ Enable the secondary communication link in the Connection Settings dialog box (see
page 36). You should then see the DNP3 Slave 2 branch in the Standalone Settings
dialog box.

‰ In the Standalone Settings dialog box of SMP I/O Manager, there are no binary output data
points configured on the CPU card:

‰ If both relays on the CPU card are configured as Watchdog and/or Remote/Local relays,
this is the expected behavior, since no DNP3 data points are required to control the relays

110 • SMP I/O User Manual

 in theses modes.

11.4 Communication Problems

Communications problems can arise between the SMP I/O and SMP I/O Manager or the master
station. Here are the most frequent problems and suggested solutions:

‰ SMP I/O Manager is no longer able to detect and contact the SMP I/O:

‰ Verify that the SMP I/O has properly started: the front panel ST LED should be green, or
red if the SMP I/O has started into Safe mode.

‰ If the SMP I/O has properly started, try adding the SMP I/O manually, as described
in the “Manually Adding an SMP I/O to the List” section, page 43. If it still does not
work, try resetting the SMP I/O to its default IP address, as described in the
“Resetting the SMP I/O’s IP Address to Default”, page 110, and then retry adding it
manually using the default IP address.

‰ If the SMP I/O keeps rebooting, the firmware application file may be corrupted. Try
uploading another application firmware file, as described in the “Manually
Uploading a File to the SMP I/O” section, page 109.

‰ The master station (or the SMP Gateway) is not able to establish DNP3 communication with
the SMP I/O:

‰ Verify that a power supply is connected and that the SMP I/O is started. The ST LED on
the front panel should be green.

‰ Make sure the RS-485 or Ethernet wiring was made correctly.

‰ Make sure the software firewall is correctly configured or disabled on the SMP I/O (See
“Updating the Connection Settings”, page.36 for more details).

‰ Make sure the DNP3 link addresses specified in the Connection Settings dialog box of
SMP I/O Manager (see page 36) of the SMP I/O correspond with the ones specified on
the master station side.

‰ The DNP3 data communication link resets often and/or the master station (or the SMP
Gateway) receives erroneous responses:

‰ Verify that the inactivity timeout is large enough. Try increasing the value of this
timeout. If the SMP I/O is used as a standalone I/O module, you can change the inactivity
timeout setting in the Standalone Settings dialog box of SMP I/O Manager (see
page 36); if the SMP I/O is used as a companion to the Cybectec SMP Gateway, in the
“General Settings” view of the SMP I/O protocol in SMP Config (see page 49).

‰ If the SMP I/O is used in a multidrop (RS-485) configuration, verify that unsolicited
reporting is disabled for the data communication link that uses RS-485. If the SMP I/O
is used as a standalone I/O module, you can change the unsolicited report setting in the
Standalone Settings dialog box of SMP I/O Manager (see page 36); if the SMP I/O is
used as a companion to the Cybectec SMP Gateway, in the “General Settings” view of

SMP I/O User Manual • 111

 the SMP I/O protocol in SMP Config (see page 49).

‰ The secondary communication link doesn’t seem to work:

‰ Make sure the secondary link was configured both in the connection settings dialog box
of SMP I/O Manager (see page 36) and the Standalone Settings dialog box (see “DNP3
Slave Settings”, page74).

‰ Keep in mind that the secondary communication link uses TCP port 20001 by default,
instead of the standard default 20000 port. Modify the communication settings of the
secondary master station if needed, or change the port number of the secondary
communication link (see “Updating the Connection Settings”, page 36).

11.5 Problems with Data Validity

Data validity problems may be encountered on either one of the DNP3 data communication link.
Here are the most frequent problems and some suggested solutions:

‰ Timestamps of events are incorrect:

‰ The SMP I/O may not be time-synchronized. Make sure that an IRIG-B source is
correctly wired to the SMP I/O. If DNP3 time-synchronization is the preferred
synchronization method, make sure it is enabled both on the SMP I/O side and the master
station side. To enable it on the SMP I/O via SMP I/O Manager, select the DNP3 Time
Synchronization option in the appropriate slave of the Standalone Settings dialog box
(see “DNP3 Slave Settings”, page 36). For an SMP I/O used with an SMP Gateway, see
“General Settings”, page49).

‰ Some IRIG-B sources do not provide the year information field. If it is the case, DNP3
time-synchronization must also be enabled both on the SMP I/O side and the master
station side. The SMP I/O will then use the year information provided by the DNP3
master station, and the rest of the timestamp will be provided by the IRIG-B source.

‰ Transitions on a given input are reported with a bad quality:

‰ The voltage at the input is probably out of the validity ranges. See “Voltage Ranges”,
page 17, to verify if the voltage respects the on/off thresholds according to the card
nominal voltage.

‰ Verify the model of the card to make sure that the input card that was installed is the
expected one.

‰ Either one of the cards I/O status LEDs on the front panel is red:

‰ The voltage at the input is probably out of the validity ranges. See previous item.

‰ Using two communication links, if a given counter is frozen via one link, the counter seems to
be frozen also on the other link. Is this a bug?

112 • SMP I/O User Manual

 ‰ This behavior is by design. For more details, see “Monitoring Inputs”, page 18.

11.6 Problems Executing Control Operations

Here are the most frequent control operation problems and some suggested solutions:

‰ Control operations always fail:

‰ Make sure the SMP I/O has not been put in Local mode: if it is the case, the
Local/Remote led on the front panel is red. Press the L/R button for 5 seconds to revert
to Remote mode.

‰ The L/R button located on the front panel doesn’t seem to work:

‰ The button has probably been disabled by configuration. Open SMP I/O Manager and
clear the Disable Local/Remote switch on the SMP I/O checkbox in the connection
settings (see “Disabling the Local/Remote Button on the SMP I/O”, page 40).

Note 1: A Default Variation refers to the variation responded when variation 0 is requested and/or
in class 0, 1, 2, or 3 scans. Default variations are configurable; however, default settings for the
configuration parameters are indicated in the table above.

Note 2: For static (non-change event) objects, qualifiers 17 or 28 are only responded when a
request is sent with qualifiers 17 or 28, respectively. Otherwise, static object requests sent with
qualifiers 00, 01, 06, 07, or 08, will be responded with qualifiers 00 or 01. (For change-event
objects, qualifiers 17 or 28 are always responded.)
