Depending on the priority of the alarm, your meter’s display also flashes. You can
view and acknowledge active alarms and historic alarms and events through the
display and software webpages. An active alarm becomes a historic alarm when
the alarm condition no longer exists.

Meter internal web server feature

Your meter’s internal web server provides quick and easy access to real-time
energy and basic power quality information without special software using an on-
board web server combined with an Ethernet port.
The built-in web pages display selected energy and power quality information
through the web-enabled device; these pages also support basic meter
configuration.

Email messaging feature

You can configure your meter to automatically email information, whether

notification of a high-priority event or a regularly scheduled send of logged data, to
an external email address.
Specify the type of event that triggers an email alert, such as a power quality
disturbances or interval for logged data. Email messages from your meter are
received like any other email message.

Supported protocols
Your meter’s fundamental protocol and architecture is ION.
You can integrate the meter into various industry-standard networks. Data that the
meter measures can be made available to other devices using Modbus, DNP 3.0
and SNMP as well as the MV-90 translation system. You can configure the meter
to import data from other devices on these networks. Your meter supports the IEC
61850 protocol and COMTRADE waveform data format.
Your meter also supports IPv6, DPWS and RSTP Ethernet protocols.

Panel-mount meter and remote display mounting and wiring

recommendations
There are supplemental mounting and wiring recommendations that apply to
panel-mount meters and remote displays.
• The meter is intended to be mounted inside a ¼-DIN panel cutout.
• Inspect the gasket (installed around the perimeter of the display) and make
sure it is secured properly and not damaged.
• The meter retainer clips, located on either side of the meter base and used to
secure the meter in the panel, do not usually require any tools to install. If
necessary, for panels with limited space, you can use a long-handled slot
screwdriver to help install the meter retainer clips.
• The remote display can only be used with the DIN meter; it cannot be used by
meters with an integrated display.
• The remote display’s power and communications is provided through a single,
direct, point-to-point connection from the remote display to the DIN meter.

Power system wiring

You can connect the meter’s voltage inputs directly to the phase voltage lines of
the power system if the power system’s line-to-line or line-to-neutral voltages do
not exceed the meter’s direct connect maximum voltage limits.
The maximum voltage allowed for direct connection may be lower than the
manufacturer-specified limits, depending on the local electrical codes and
regulations.
If your system voltage is greater than the specified direct connect maximum
voltage, you must use voltage (potential) transformers (VTs/PTs) to step down the
voltages.

RS-485 wiring
Connect the devices on the RS-485 bus in a point-to-point configuration, with the
(+) and (-) terminals from one device connected to the corresponding (+) and (-)
terminals on the next device.

RS-485 cable
Use a shielded 2 twisted pair or 1.5 twisted pair RS-485 cable to wire the devices.
Use one twisted pair to connect the (+) and (-) terminals, and use the other
insulated wire to connect the C terminals
The total distance for devices connected on an RS-485 bus should not exceed
1200 m (4000 ft).

7EN02-0374-01 25
PowerLogic™ ION7400 series Hardware reference

RS-485 terminals
C Common. This provides the voltage reference (zero volts) for the data plus and data minus
signals

Shield. Connect the bare wire to this terminal to help suppress signal noise that may be
present. Ground the shield wiring at one end only (either at the master or the last slave
device, but not both.

- Data minus. This transmits/receives the inverting data signals.

+ Data plus. This transmits/receives the non-inverting data signals.

NOTE: If some devices in your RS-485 network do not have the C terminal,
use the bare wire in the RS-485 cable to connect the C terminal from the meter
to the shield terminal on the devices that do not have the C terminal.

Ethernet communications connections

Your meter’s dual port Ethernet connections enable you to use straight-line or
network loop (ring) topologies.
If local network loop Ethernet topologies are required, you must enable RSTP for
your meter’s Ethernet communications to function.
Only use CAT5/5e/6/6a Ethernet cables to wire your meter’s Ethernet
communications.

Option modules overview

Option modules are ordered separately from your meter, and can be connected to
your meter without specialized equipment.
Option modules are identified based on the physical order of the attached
modules. The option module attached directly to the meter is module A, the
module attached to module A is module B, and so on. The option module identifier
is added to the ION module name and ION label to uniquely describe each
possible combination of option modules.

A Option module A

B Option module B

C Option module C

D Option module D

E Meter

For example, a meter with two option modules, consisting of an analog option
module directly attached to the meter (A) and a digital option module attached
second (B), describes the Q2 analog output of module A as Port A Q2 and the S3
digital input of module B as Port B S3.

26 7EN02-0374-01
Hardware reference PowerLogic™ ION7400 series

Maximum number of option modules

The maximum number of option modules supported by the device is four. However,
there are limitations.
Depending on the type and quantity of option modules attached to your meter, you
may need to reduce your meter’s maximum operating temperature or limit the
number of option modules. Refer to Maximum operating temperature, page 196
for more information.
For a panel mount meter, one limitation on the number of modules that can be
attached is the physical strength of the meter mounting hardware. If your meter is
mounted in an area subject to vibration or other physical stresses, your meter’s
ability to physically support multiple option modules and maintain a seal against
the mounting surface may be affected. Refer to Mechanical characteristics, page
193 for more information.

NOTICE
EQUIPMENT DAMAGE
Do not exceed the maximum number of option modules.
Failure to follow these instructions can result in equipment damage.

USB (integrated display only)

Models with an integrated display have USB ports.
You can use the mini–B USB port to connect to a computer running ION Setup to
configure your meter. Other applications, programs and protocols are not
supported.
NOTE: It is not recommended to use your meter’s mini–B USB port to upload
firmware or paste templates because of long file transfer times.
The type A USB port is reserved for future use.

USB port location

The USB ports are located on the meter’s integrated display under a protective
cover.
Flip the USB port cover up to expose the USB ports. Replace the USB port cover
when the ports are not in use to help keep the USB ports clean.

Security
Security overview
Your Schneider Electric product is equipped with security-enabling features.
These features arrive in a default state and can be configured for your installation
needs. Please note that disabling or modifying settings within the scope of these
individual features can impact the overall security robustness of the device and
ultimately the security posture of your network in either positive or negative ways.
Review the security intent and recommendations for the optimal use of your
device’s security features.
Products are hardened to increase security robustness. This is an ongoing process
consisting of secure development practices, inclusion of security features and
testing at our security test facilities. Following system hardening best practices is
also necessary to help ensure your overall system security.
See the Cybersecurity Hardening Best Practices white paper for suggested best
practices.

Security features on your device

Your device comes with security features that you can configure to help protect
against unauthorized configuration and access to your device’s data through its
user interfaces or communications.

Network port control

This feature provides you with the ability to enable and disable individual network
ports and to change port numbers from their default values.
Leaving unused ports open provides additional attack surfaces for a potential
attacker. Minimizing the number of ports open on the device reduces the likelihood
of unauthorized intrusions by providing fewer entry points.
Once your meter is configured, all network ports related to unused protocols
should be placed in the OFF state/position. Minimize the number of open ports,
temporarily opening ports for activities such as periodic firmware / software
downloads when required.
Network ports that remain open should be changed from their default values
wherever possible.

Related Topics
• Network protocol control
• Ethernet configuration

Enable/disable communication ports

You can disable physical communication ports when they are not in use.
These can be disabled through the display, ION Setup or through the meter’s
webpages.
Leaving unused ports open provides additional attack surfaces for a potential
attacker. Minimizing the number of ports open on the device reduces the likelihood
of unauthorized intrusions by providing fewer entry points.

Revenue and billing security features

Selected meter models support additional hardware and firmware locking to
prevent unauthorized access to revenue-related parameters and settings.

Event logging
Your meter records meter functions, events and changes to meter parameters and
logs them as entries in the event log.
Event logs entries are timestamped and user-related events are associated with
the username that was logged into the meter. Security-related events such as
resets, successful or unsuccessful login attempts, user lockout or meter
configuration changes are also recorded in the event log along with a timestamp
and the username associated with the event. The event log can be used to monitor
system events, assist in confirming security compliance, or assist in tracking
unauthorized intrusion attempts.

Related Topics
• User triggered event log entries

Syslog
This feature allows you to push event log information to a centralized syslog
server.
When the event log of a meter is full, new log entries can overwrite existing entries.
By pushing the event log information to a syslog server, older event log information
can be preserved and used as part of an information storage and retrieval strategy.

Advanced security through the meter’s display

Advanced security is available through the meter’s display.
When advanced security is enabled on your meter, user privileges created through
ION Setup are enforced through the meter’s display. When advanced security is
enabled, changes to meter configuration are associated with the username that is
logged into the meter. The advanced security password used to access the meter
uses an expanded character set, allowing for a more robust password.

NERC CIP
North American Electric Reliability Corporation (NERC) Critical Infrastructure
Protection (CIP) is a set of standards and requirements designed to help protect
the North American power generation and transmission system and covers
aspects such as critical cyber asset identification, electronic security perimeters,
and systems security management.
This meter has incorporated security features that allow it to be part of NERC CIP
compliant facility. For example, the security features of this meter include user
accounts with configurable passwords and permissions; network port control
configuration; security access and event log replication to an external server; and
digitally signed firmware.

Security configuration process

The security configuration process has four basic steps: review security
recommendations, set basic security options, configure communications protocol
lockout settings, and configure users.
1. Review security recommendations
2. Set basic security options
• Change the display (front panel) password.
• Disable broadcasting time synchronization (advanced security only).
• Enable/disable display (front panel) and Webserver programming.
• Enable/disable Modbus programming (advanced security only).
3. Configure communications protocol lockout options
a. Configure protocol-specific settings:
• Set the number of attempts before the protocol is locked out.
• Set the session timeout.
b. Configure global lockout settings:
• Enter a lockout duration.
• Set the priority of meter access events.
4. Configure users (advanced security only)
• Determine user access.
• Set user passwords.

Communications protocol lockout overview

The communications protocol lockout security feature allows you to set the number
of invalid login attempts that each user can make using a particular protocol and
communications method before being locked out (a user is defined as a user login
and password combination).
For protocols that are not session-based (ION), you can configure how often the
device registers invalid login attempts by configuring the session timeout. You can
also configure the lockout duration for all configurable protocols.
Session timeout specifies the active duration for a protocol; during this time,
repeated invalid login attempts using the same USER/password combination are
not registered (repeated invalid attempts with different combinations are still
registered). Session timeout only applies to protocols which are not session-based
(ION) and send credentials with each packet, and should be configured to help

46 7EN02-0374-01
Security PowerLogic™ ION7400 series

prevent accidental lockouts and filling the meter’s event log with protocol access
events
NOTE: If protocol lockout is set to 0 (zero) there is no limit to the number of
invalid login attempts and the protocol will never be locked out. However, the
invalid login attempt events are recorded if the meter access events are
configured to record invalid access attempts.

passwords to attempt access
to the meter
User 1 Us e r1 Us e r1 Us e r2

Once a user is locked out, the device will not accept login attempts from that user
on that protocol and communications method until the lockout duration has
passed. Invalid login attempts accumulate until the user has completed a valid
login or is locked out. If the user enters the correct USER/password combination
before being locked out, the invalid attempt counter is reset to zero. Even if the
user is locked out using ION over Ethernet, that user can still access the device by
entering the correct USER/password combination over a different protocol and
communications method (for example, connecting to the device’s RS-485 serial
port using Modbus protocol).

7EN02-0374-01 51
PowerLogic™ ION7400 series Communications

Communications
Communications overview
Your meter supports several different protocols over its Ethernet and serial
connections.
Your meter’s default protocol implementation meets the needs of most systems
with only basic configuration. You can customize these implementations to meet
your specific needs. These are advanced procedures that require an
understanding of your meter’s architecture, the supported protocols, and the
communications network and power system that your meter is connected to.

Ethernet communications
The meter supports a single IP address on both of its two physical Ethernet
connections.
Your Ethernet connection source should be installed in a location that helps
minimize the overall Ethernet cable routing length and complexity of your network.
Your device’s second Ethernet port acts as an Ethernet switch to help simplify
network connections and reduce installation time and costs, by having shorter
Ethernet cable runs between devices without needing additional Ethernet routers
or repeaters. You cannot connect your meter to two different Ethernet networks.
The two Ethernet ports do not split the signal, so connecting both of the ports
should not impact your communications speed.
The meter uses dual-stack IPv4/IPv6 routing technology to manage network
communications and allow network hosts to communicate with the meter using
either IPv4 or IPv6.

Protocols, ports and connections

The Ethernet protocols supported by your device allow simultaneous connections
through the IP service ports.
NOTE: Not all port numbers are configurable for all protocols.

Self-discovery over Ethernet

Your meter supports DPWS (devices profile for web services) which allows for self-
discovery of the meter when it is connected to your local area network.
When you connect your meter to your network, your meter automatically appears
in your network in Windows Explorer under Other Devices. By default, the meter is
named <meter type>_<last six digits of MAC address>. For example, a meter with
a MAC address of 0060784173393 appears on the network as <meter type>_
173393.

A Meters with self-discovery over Ethernet connected to the network

B Local area network (common subnet, no routers)

C Computer connected to the network with IPv6 enabled

Considerations for using self-discovery over Ethernet

• For self-discovery, the meter must be connected directly to the network using
only a cable or switches, and not going through a router.
• You must use a computer running Windows 7 or later with IPv6 enabled in
order to use self-discovery over Ethernet.
• The computer and the meter must be on the same subnet.
• You do not need to configure your meter’s IP address for self-discovery over
Ethernet; an IPv6 address is automatically generated from your meter’s MAC
address and self-discovery takes place over IPv6.

Accessing the meter through self-discovery

You can use Microsoft® Windows Explorer to locate and access the meter on your
local network.
NOTE: Some networks restrict device self-discovery over a wireless
connection. If this is the case, make sure your computer is connected to the
network using an Ethernet cable.

Ethernet configuration
In order to use Ethernet communications, you must configure your device’s IP
settings.
You need to enter network information for any Ethernet servers used by the device
(for example, a DNS or email server). Contact your network system administrator
for your IP address and other Ethernet network configuration values.
NOTE: For meters that do not have a display, you must connect your meter
directly to your computer to set a unique IP address for each device or
configure the meter to use a DHCP server to acquire IP addresses.
It is recommended that you test your communications with the meter after
changing any communications-related settings (for example, communicating with
the meter using the fully-qualified domain name if using DNS or with assigned
addresses after these are provided by the DHCP server). In addition, make sure
that any software or other devices communicating with the meter are using the new
settings.

Initial Ethernet configuration versus changing existing Ethernet settings

There are two scenarios when configuring your meter’s Ethernet communications
settings: initial configuration and changing the existing addresses when the meter
is in use.
• Initial configuration: Configure your device’s Ethernet settings manually using
the display or by connecting your meter directly to your computer and using a
web browser to access the device’s webpages. Alternately, you can connect
your meter to the network and configure it to use a DHCP server to acquire an
IP address.
NOTE: It is recommended during initial configuration that you use a
connection method other than the one your are trying to configure. For
example, if you are configuring DHCP IPv4 settings, connect to the meter
using the IPv6 LinkLocal address or a serial connection. This allows you to
configure the meter without being disconnected.
• Changing existing IP settings: After the meter’s Ethernet port is configured
and connected to the LAN, you can use ION Setup to configure meter
settings, in addition to using the display or meter webpages.
In either case, modify your meter’s Ethernet settings to those provided by your
network system administrator before connecting the device to your local area
network (LAN).

IP address format and ranges

When you set your meter’s IPv4 or IPv6 addresses, make sure you use the correct
format and valid ranges.

Protocol Format
IPv4 0.0.0.0 to 255.255.255.255
IPv6 :: to FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:
FFFF
The double colon indicates that gaps are filled
with zeroes to make the IPv6 address the correct
length (32 hexadecimal numbers)

54 7EN02-0374-01
Communications PowerLogic™ ION7400 series

All meters ship from the factory with the IPv6 global address and IPv6 gateway
undefined (set to “::”). To communicate with the meter using IPv6 outside the local
network, you must configure these settings manually or use DHCP to assign the
addresses to the meter. Within the local network, you can use the meter’s IPv6
Link Local address.

IP addresses and network port numbers

To specify a port for an outgoing IP address, append a colon (:) then the port
number to the end of the IP address. For IPv6 addresses, make sure the address
is enclosed in square brackets then append the port number. For example, to
specify the default port for ftp (port 21), the format of the address is as follows:
• IPv4: 169.254.0.10:21
• IPv6: [FE80::260:78FF:FE04:5943]:21

DHCP
The meter can function as a DHCP (Dynamic Host Configuration Protocol) client,
allowing a DHCP server to assign IP addresses to the meter.
The meter supports assignment of the following addresses by a DHCP server
when the Assignment Mode is set to DHCP:
• IPv4 IP Address
• IPv4 Subnet mask
• IPv4 Gateway
• IPv6 Global Address
• IPv6 Gateway

Considerations for using DHCP

• It is recommended that you also set up a DNS server and configure software
and other devices to use the meter’s name to communicate with it.
Alternatively, you can configure the DHCP server to always provide the same
address to the meter.
• When you switch the assignment mode from DHCP to Stored, the meter
reverts to using its default IP addresses as the Stored addresses.
• When you switch the assignment mode from Stored to DHCP, the acquired
addresses display as None until the meter receives addresses from the DHCP
server.
• When using IPv6, the meter’s fully-qualified domain name (FQDN) is not sent
to the DHCP server. It is important that you make sure what is configured on
the meter matches what is configured on your network.
• If the meter is not able to communicate to the DHCP server:
◦ When using IPv4, the meter will try to connect to the DHCP server for
approximately one minute. If the meter cannot connect to the DHCP server,
it will revert to the default IP address, but the Assignment Mode will remain
DHCP.

62 7EN02-0374-01
Communications PowerLogic™ ION7400 series

◦ When using IPv6, the meter will continue to try to connect to the DHCP
server, even if it does not receive an address.
◦ For IPv4, if the meter’s fully-qualified domain name (FQDN) is not found on
the DHCP server, an event is logged in the event log. For IPv6, if the
meter’s fully-qualified domain name (FQDN) is not found on the DHCP
server, no event is logged; this is important to keep in mind when
troubleshooting communications issues in a system using DHCP.

The meter’s domain name

You can configure the meter as a DNS client in systems using a DNS server.

Domain name resolution (DNS)

A DNS (domain name system) server maps domain names to IP addresses. If you
configure the meter to use a DNS server, the meter can communicate with other
network resources using their domain names, rather than their IP addresses, and
vice versa. For example, if your network has an SMTP server with the domain
name of smtp.company.com, you can enter smtp.company.com as the SMTP
Server address in the meter’s communications settings.

The meter’s fully-qualified domain name (FQDN)

To allow other network resources to communicate to the meter using its domain
name, you must configure the meter’s Ethernet Device Name setting to match that
used by the DNS server. The meter’s fully-qualified domain name is its Ethernet
name plus its Domain name. For example, if the meter’s Ethernet name is
ElectricityHQ and its Domain name is companyXYZ.com, the FQDN will be
ElectricityHQ.companyXYZ.com.
NOTE: This domain name is used for both IPv4 and IPv6 communications. It is
used to identify the meter in a system using DNS and to identify the meter
when using DPWS for self-discovery over Ethernet.

Ethernet topologies
When wiring your meter’s Ethernet communications, it is recommended to only use
straight-line topology.
If local network loop or ring Ethernet topologies are required, you must enable
RSTP (rapid spanning tree protocol) for your meter’s Ethernet communications to
function.

Network protocol control

The network protocol control feature allows you to enable, disable or change the
port number of the network protocols supported on your meter.
Disabling unused ports is considered a cybersecurity best practice to help
minimize unauthorized access to your meter.
NOTE: The protocol port number may not be configurable on all protocols.

Configuring network protocol control using the meter display

The Ethernet Port Enable Setup allows you to enable or disable your network
protocols through your meter’s display.
When configuring communications parameters, ensure you maintain at least one
communication path that allows full access to your device; otherwise you may
permanently lose the ability to change your device’s configuration and access to
additional data.

Serial communications
The meter supports serial communications through its RS-485, optical and USB
ports.

RS-485
In an RS-485 network, there is one master device, typically an Ethernet to RS-485
gateway. It provides the means for RS-485 communications with multiple slave
devices (for example, meters). For applications that require only one dedicated
computer to communicate with the slave devices, a USB to RS-485 converter can
be used to connect to the master device.
Up to 32 devices can be connected on a single RS-485 bus.

Optical
Your meter’s integrated display has an optical port used for communicating with
your meter using an optical probe. Your meter’s optical port can also be configured
for energy pulsing.

USB
Your meter’s integrated display has a mini-B USB port which is used to configure
your meter with a computer running ION Setup.

RS-485 configuration
Before connecting your device to the RS-485 bus, use the meter’s display,
webpages or ION Setup to configure your meter’s default RS-485 settings.
Your meter has one RS-485 connection.
Your meter must have a unique unit identifier (address) and have the following
settings match the rest of the devices on the RS-485 bus:
• Protocol
• Baud rate
• Parity and stop bits
You can configure the following settings to help optimize communications
performance:

ION
ION is the native protocol and architecture of your meter.
The basic building blocks of ION architecture are the ION modules, each of which
is specialized to perform a specific task and contains data and instructions on how
to manage that data. ION modules are combined (linked) together to create the
meter’s functions and features. ION modules that are linked together to perform a
specialized task are called a framework, such as the Power Quality framework.
These different functional frameworks are then grouped together to define the
entire meter, and are collectively referred to as the device template.
Your meter ships with a default device template which provides extensive
capabilities. You can also configure your meter’s template to modify your meter’s
existing functions or to create new functions.
See the ION Reference, available from www.schneider-electric.com for further
information about ION architecture and a detailed description of the different ION
modules. See the ION Device Template Reference, available from
www.schneider-electric.com, for details on the modules and their configuration in
your meter’s default template.

Modbus
Modbus is a master/slave communications protocol where the master initiates
transactions and the slave(s) responds with the requested information or action.
Your device can function as a Modbus slave or Modbus master, depending on how
it is configured. Your device comes with Modbus slave functionality configured and
ready to use. You can add custom Modbus information to the default Modbus slave
data provided by your device.

regardless of the slave device’s actual unit ID.

Modbus implementation
Your meter's Modbus implementation includes exception codes, invalid register
responses, fixed and configurable register maps, and security.

Modbus exception codes

Code Name Description

01 Illegal function The requested command is invalid.

02 Illegal address This code indicates one of the following:

• The requested address is invalid for that function.
• The requested address is not within the valid register
range for this device.
• The requested address is protected by device
security.

03 Illegal value This code indicates one of the following:

• The requested value is not allowed for that register in
the device.
• The requested register is part of a multi-word value.

Modbus invalid read registers responses

Ethernet gateway
Ethernet gateway is a communications method that allows you to communicate
through a gateway device to a serial network.
When a meter with gateway capabilities is installed on an Ethernet network, a
master device (such as an energy management system) can communicate through
the gateway meter to a serial network of devices connected to the gateway meter’s
serial port(s). The maximum number of devices on the serial network is determined
by the limitations of the gateway meter’s serial port.
There are two types of Ethernet gateways that you can configure on your meter:
• EtherGate: a single TCP connection communicates through the gateway
meter to a serial network of devices.
• Modbus gateway: up to a maximum of 32 Modbus master TCP connections
communicate through the gateway meter to a serial network of Modbus
devices.

Related Topics
• Ethernet communications

EtherGate
The meter can function as an Ethernet gateway (EtherGate).
EtherGate is a protocol-agnostic communications method that lets you
communicate through a gateway meter to a serial network of devices letting ION or
other RTU over TCP data pass through the gateway meter to other networks,
including third party systems. When a meter installed on the Ethernet network has
EtherGate enabled, a master device (such as an energy management system) can
communicate through the gateway meter to a serial network of devices wired to the
gateway meter’s COM port. You must create an additional communications
connection to the gateway meter in order to read its information.

A D
B

A Gateway meter

B Ethernet (single TCP connection)

C Serial network of devices

D Master device (one only)

For EtherGate, you must install the serial devices, configure them and connect
them to your Ethernet-connected gateway meter. Ensure that each serial device is
configured with the same protocol and baud rate and has a unique unit ID.
Configure the gateway meter’s serial port to use the EtherGate protocol, create the
EtherGate site in ION Setup or an energy management system, and add the serial
devices to the EtherGate site.
NOTE: EtherGate supports only one master device.

Configuring EtherGate using the display

Use the meter’s display to configure a serial port to use the EtherGate protocol.
The Ethergate Ethernet protocol must be enabled for EtherGate operation.

82 7EN02-0374-01
Communications PowerLogic™ ION7400 series

1. Navigate to Setup Menu > Communications Setup and go to the serial

communications setup screen.
2. Set the serial port’s protocol to EtherGate. Configure the other serial port
parameters as required.

Configuring an EtherGate gateway using ION Setup

You can configure EtherGate on your meter using ION Setup.

Before you begin, make sure you have completed the following tasks:
• Confirm the serial network of devices are wired and configured to have the
same baud rate, serial port settings (for example, 8N1), and protocol (ION).
• Confirm each serial device has a unique unit identifier.
• Confirm the serial network of devices are connected to the gateway meter’s
serial communication port.
• Confirm your gateway meter is communicating over Ethernet.
• Confirm that the EtherGate Ethernet protocol is enabled on your gateway
meter.

1. Start ION Setup.

Modbus Ethernet gateway

The meter’s Ethernet gateway feature extends the meter’s functionality by allowing
Ethernet access to serial devices connected to the meter’s RS-485 serial
communications port.

A. Gateway meter
B. Ethernet (multiple Modbus master TCP
connections)
C. Downstream serial Modbus slave devices
D. Multiple Modbus master devices

A Modbus master device (such as an energy management system) can

communicate through the gateway meter to a serial network of devices connected
to the gateway meter’s serial port(s). The meter receives Modbus TCP/IP data on
TCP port 502, translates it to Modbus RTU then forwards it to the addressed slave
device.
This functionality allows the use of monitoring software to access information from
slave devices for data collection, trending, alarm/event management, analysis, and
other functions.

Modbus Ethernet gateway implementation

There are some specific aspects to your meter’s Modbus Ethernet gateway
implementation.

7EN02-0374-01 83
PowerLogic™ ION7400 series Communications

A Modbus request is sent through Ethernet using Modbus/TCP to the gateway

meter. If this request is addressed with the slave ID of one of the downstream
serial devices, the meter forwards the message to that device using Modbus RTU.
When the downstream device responds, the gateway meter forwards the response
back to the Modbus master. In addition to Modbus slave addresses 1 - 247, the
Modbus gateway supports slave address 255, which sends a Modbus request to
the gateway meter only.
For Modbus gateway, you must install the serial Modbus slave devices, configure
them and connect them to your Ethernet-connected Modbus gateway meter.
Ensure that each serial device is configured to communicate over Modbus with the
same baud rate and has a unique unit ID. Configure the gateway meter’s serial
port to use the Modbus master protocol and enable the Modbus gateway feature,
create a Modbus gateway site in ION Setup or an energy management system,
and add the serial devices to the Modbus gateway site.
NOTE: Modbus Ethernet gateway supports up to 32 Modbus TCP
connections.

7EN02-0374-01 85
PowerLogic™ ION7400 series Communications

FTP memory allocation

Your meter’s FTP memory usage changes when you copy a file to the meter’s
internal FTP site or modify a feature that uses the meter’s FTP site.
If you attempt to load a file onto your meter’s FTP site that is too large, your FTP
program displays an error, and you must delete files from your meter’s internal FTP
site to free up memory before loading the file.
If you modify a meter feature which uses FTP memory, such as increasing the
number of COMTRADE waveform records, the meter checks to confirm sufficient
space is available on its internal FTP site before enabling the modified feature. If
there is insufficient space, the feature is disabled, and you must delete files from
your meter’s FTP site to increase the available space before enabling the feature.

FTP file structure and permissions

Your meter has an FTP folder structure.
• COMTRADE: you can read COMTRADE files from these folders, but you
cannot delete or add files to these folders.
• IEC61850: you can add an IEC 61850 configuration (CID) file to this folder to
activate the IEC 61850 protocol functions of your meter.
• optionModuleUpg and rmdUpg: you can load firmware update files for your
meter’s remote display or option modules into these folders.
• documents: this folder is intended for user storage. You can read, write and
delete any type of files in this folder.
• web: this folder is where the meter’s default webpages are stored and where
you can add custom webpages to the meter by copying them into the
appropriate subfolders.

FTP filename requirements

FTP filenames are limited to standard ASCII characters.
This means that they cannot contain a blank space, quotation marks or \, /, *, ?, <
or >, and are limited to 68 characters in length, including the file extension. The “/”
character is only used as part of the FTP file directory information.

Simple Network Management Protocol (SNMP)

Your meter supports SNMP once you have enabled SNMP on your meter. You
need to upload the meter’s MIB file (available from www.schneider-electric.com)
into the NMS managing your meter.
Simple Network Management Protocol (SNMP) is part of the Transmission Control
Protocol/Internet Protocol (TCP/IP) protocol suite. SNMP is an application layer
protocol that enables the exchange of network management information between
devices, allowing you to manage network performance and to identify and solve
problems on networks with devices of various types.
SNMP configuration assumes that you have an advanced understanding of SNMP
and the communications network and power system that your meter is connected
to.

SNMP implementation
MIB files

Your meter is compliant with MIB-II as defined by the standard MIB file RFC 1213.
SNMP requires that you load your meter’s ION MIB file (available for download
from www.schneider-electric.com) into the NMS.
You must install RFC 1213, which is required to read basic network information for
the meter (for example, TCP/IP traffic or number of packets received), if it is not
included with your SNMP manager software.

Community strings

A community string is a text string which acts to help authenticate requests from
the NMS to your meter.
There are two community strings on your meter:
• Read Only Community: this community string is used by SNMP get (read-
only) requests. The read only community string’s initial factory-set value is
public.
• Read Write Community: this community string is used by SNMP set (read/
write) requests. The read write community string’s initial factory-set value is
private.
NOTE: You can also use the read write community string for SNMP get (read-
only) requests.
If your meter receives an incorrect community string, it generates an
AuthenticationFailure trap.

System strings

A system string is a text string which can be configured to provide information

about your meter.
There are three system strings on your meter:
• System contact: enter the name of the SNMP system administrator.

If you change your meter’s default values you must modify the custom MIB file to
reflect the new values.
Changing your meter’s default SNMP configuration assumes that you have an
advanced understanding of ION architecture, SNMP, and the communications
network and power system that your meter is connected to.
See the ION Reference, available from www.schneider-electric.com, for detailed
information on the SNMP Mapping module.

Configuring your SNMP MIB file

You must configure your MIB file if you have modified the default SNMP
information provided by the meter in order for the MIB file labels to reflect the
modified values.
Download the ION MIB file from www.schneider-electric.com.
NOTE: You should only configure the variable name and description. Changing
other fields in your MIB file may cause the client software to report problems or
return errors when trying to retrieve or view parameters.
The variable name must conform to the following rules:
• The first character must be a letter.
• The first character must be lower case.
• The name must not contain any special characters such as *, ?, &.
• The name must not contain spaces.

1. Open your meter’s MIB file in a text editing program (such as Notepad).
2. Update the variable name and description so they match the meter values
connected to the SNMP Mapping module.
3. Save your meter’s MIB file. Make sure you keep the original file extension of .

DNP
Your meter can be integrated into a DNP network as a DNP slave.
The Distributed Network Protocol Version 3.0 (DNP 3.0) is an open protocol used
in the electric utility industry for communications and interoperability among
substation computers, Remote Terminal Units (RTUs), Intelligent Electronic
Devices (IEDs, e.g. meters), and master stations.

DNP supported features and default implementation

Your meter is pre-configured for basic DNP Slave functionality.

7EN02-0374-01 93
PowerLogic™ ION7400 series Communications

Your meter supports a maximum of three concurrent connections (sessions) using

the DNP 3.0 protocol; one for each serial port, up to three using Ethernet, or a
combination of both. Combinations available depend on the meter's
communications options. A session consists of all incoming and outgoing DNP
Master/Slave traffic on one of the meter's communications ports.
For serial DNP communications, you must assign the DNP protocol to the
appropriate serial communication port on your meter; you do not have to configure
your meter’s Ethernet port(s).
You can modify your meter’s default DNP map using configuration software.
Data can be imported into the meter from a DNP control relay or analog output
device. This is an advanced feature intended for users with an in-depth
understanding of the DNP 3.0 and ION protocols.
See the online ION Setup help for instructions on connecting to your meter and
accessing the Setup Assistant, which can be used to modify your meter’s DNP port
settings and default DNP map. Go to www.schneider-electric.com to download
your meter’s DNP 3.0 device profile document for detailed information on your
meter’s default DNP map and implementation and the Multiport DNP 3.0 and ION
technology technical note for more information on how your meter supports DNP
3.0.

Time and timekeeping PowerLogic™ ION7400 series

Time and timekeeping

Time overview
Your meter supports different time types and time synchronization methods to
adjust its internal clock.
Your meter’s internal clock is used for keeping time, timestamping data and
determining intervals for time-based measurements. The meter’s clock does not
affect externally logged data.
Your meter monitors the passage of time using the frequency of an internal
oscillator or the frequency of the line power being measured. You can view your
meter’s time and date information using the display or through software. To
improve your meter clock’s accuracy, you can use an external time reference, such
as a Global Positioning System (GPS) signal.
Your meter’s battery maintains the internal clock when the meter is unpowered.
Your meter displays local time based on the meter’s time sync source and settings
for timezone and daylight savings time. You can configure your meter’s date and
time format.
Go to www.schneider-electric.com and download the Time synchronization and
timekeeping technical note for more information about time formats and settings
and the ION Reference for a detailed description of the Clock module and its
operation.

Internal clock temperature compensation

The time accuracy of the meter has been improved by compensating for clock drift
if the meter’s operating temperature falls outside the optimum temperature range.
Your meter’s internal clock is adjusted based on the internal clock temperature
compensation parameters.

Internal clock temperature compensation parameters

Your meter’s internal clock is adjusted based on the temperature profile of its
components.

Time synchronization overview

The time synchronization source and the duration between time synchronization
messages determines the accuracy of the meter’s clock.
The clock is adjusted by synchronizing the meter’s time with another time source.
Time synchronization messages can be automatically generated and sent to your
meter from your energy management system software or other time source such
as an SNTP/NTP server or GPS receiver. You can also manually trigger a time
synchronization message from your energy management system or configuration
software.

7EN02-0374-01 95
PowerLogic™ ION7400 series Time and timekeeping

NOTE: To help maintain data integrity, some energy management systems

impose a blackout rule where time synchronization messages near energy
interval boundaries are ignored.

Supported time synchronization sources

Several time synchronization sources are available to your meter.

Time sync source Description

Meter configuration software (ION Setup) Configuration software can manually

synchronize the time of your meter based on the
clock of the computer running the configuration
software. Configuration software synchronization
is usually performed when the meter is initially
commissioned.
Energy management system Energy management systems can synchronize
the time of your meter to be consistent with other
meters on the network.
Simple Network Time Protocol (SNTP) SNTP can synchronize the time of your meter up
to ± 1 second of other meters on an Ethernet
network. For SNTP time synchronization, your
meter must be connected to an Ethernet network
that has an active SNTP server and be
configured with the server’s information.

GPS receiver (IRIG-B)1 A GPS receiver using IRIG-B can synchronize

the time of a meter up to ± 1 ms of Coordinated
Universal Time (UTC). A dedicated serial
network is required to implement a GPS
scheme. For IRIG-B, one of your meter’s digital
inputs must be connected to the IRIG-B network,
and the digital input must be configured for IRIG-
B time synchronization in addition to configuring
your meter’s clock.

GPS over serial A GPS receiver can synchronize the time of a

meter up to ± 1 ms of Coordinated Universal
Time (UTC). For GPS over serial, your meter’s
serial port must be connected to a GPS receiver,
and the serial port communications must be
configured with the correct protocol setting.

Network Time Protocol (NTP) NTP can typically synchronize the time of a
meter to ± 10 to 100 ms, depending on network
configuration. To implement NTP time
synchronization, your meter must be connected
to an Ethernet network that has an active NTP
server and be configured with the server’s
information.

1 Use the digital inputs located on the meter base for IRIG-B time synchronization
and other high-accuracy applications.

GPS time quality flag

The meter’s GPS time quality flag is primarily used to report time quality
information for digital input events, such as status alarms, in Sequence-of-Events
Recording (SER) applications.
The meter keeps track of the time difference between the meter’s internal clock
and the GPS time sync source. When the meter’s Clock module’s Use GPS
Quality Flag is set to USE FLAG, the Diagnostics module’s GPS Receiver Status
output register is set to:
• LOCKED if the time difference between the GPS time sync source and meter
clock is within ±1 ms of each other
• UNLOCKED if the time difference between the GPS time sync source and meter
clock is greater than ±1 ms of each other

Firmware and templates
Firmware and template overview
You can load different firmware versions and templates onto your meter.
Firmware is your meter’s operating system that enables the functions of your
meter. Your meter’s template defines the meter’s features such as its power
measurement and analyzing functionality. Your meter ships from the factory with a
default template, or you can customize your meter’s template to create features
specific to your meter’s application. You can save your customized template and
upload it to other meters of the same type.
You can view your meter’s firmware version on your meter’s display, webpages
and through ION Setup.
You can upgrade your meter’s firmware and template using ION Setup. Firmware
updates and new factory templates are available for download from
www.schneider-electric.com.

Firmware overview
Firmware is your meter’s operating system.
When new firmware is available for your meter, you can upgrade to the latest
version to get the added features and functionality. The firmware version loaded on
your meter is shown on your meter’s display. You can use ION Setup to upgrade
the firmware on your meter.
The meter’s firmware includes a digital signature, which helps ensure the
firmware’s authenticity.
You must load a meter template as part of the firmware upgrade process. You can
save your meter’s existing template before performing a firmware upgrade and
then reload it back onto the meter if you do not want to change your meter’s
template.
Your meter’s remote display and option modules use firmware information from the
meter, but they may also need to have their internal firmware updated to support
new or improved features. To load and update to your meter’s remote display
firmware, you need to copy the file to your meter’s internal FTP server. You can
download firmware files from www.schneider-electric.com.
See the online ION Setup help, available from www.schneider-electric.com, for
more information about downloading, saving and loading your meter’s template.

Typical workflows
To update your meter to the latest available firmware and factory template:
• Download the latest firmware and template for your meter.
• Load the firmware onto your meter; the firmware upgrade process includes
upgrading the meter template.
To take an existing meter out of service and replace it with a new meter:
• Save the template from the existing meter
• Load the existing meter’s template onto the new meter; the new meter will now
have the customized features from the existing meter.
To update your meter’s firmware without updating your meter’s template:
• Save your meter’s template.
• Download the latest firmware.
• Load the firmware onto your meter. When prompted for a template file, select
the template you saved from your meter.

100 7EN02-0374-01
Maintenance PowerLogic™ ION7400 series

To update the firmware on your meter’s remote display:

• Download the display firmware.
• Load the firmware onto the meter’s internal FTP site using either an FTP
program or ION Setup. The results of the firmware update are stored in the
meter’s event log.
To update the firmware on your meter’s option module(s):
• Download the option module firmware; make sure that the firmware matches
the option module type.
• Load the firmware onto the meter’s internal FTP site using either an FTP
program or ION Setup.
• Power cycle or perform an option bus reset to start the option module firmware
NOTE: If the meter is power cycled or an option module reset is performed
while there are option module firmware upgrade files loaded on the meter’s
FTP site, the option module firmware is upgraded.
Visit the company website at www.schneider-electric.com and search for your
meter type to see the available firmware and templates.
See the online ION Setup help for instructions on how to load meter templates.

Laptop computer upgrade considerations

The connection between the laptop and the device must be maintained in order for
the upgrade to proceed.
Laptop computers generally have different default power properties than desktop
computers.
If the laptop’s hard disk shuts down or the laptop enters system standby mode, this
connection is broken and the upgrade procedure must be restarted.
If you are upgrading your meter’s firmware using a laptop computer, follow these
guidelines:
• Plug the laptop computer into a wall outlet. Do not run the laptop on its battery.
• Configure the laptop’s hard disks so that they do not shut down after a certain
period of time (for example, set to “never”).
• Turn off the laptop’s power suspension (for example, system stand-by) and
hibernate options.
• Disable the laptop’s option to power down when it is closed. This prevents a
shut down if the laptop is accidentally closed.
• Disable the laptop’s screen saver as they can burden the CPU.

Firmware upgrade considerations

Ensure that the firmware version you are upgrading to is compatible with your
meter, and that the version number is greater than your existing firmware (or else
you will downgrade your meter).
Your meter’s existing template may not work with different firmware versions if
significant meter features have been added or modified.
Your firmware upgrade files have digital signature confirmation to help ensure your
firmware’s authenticity. Once you have upgraded your firmware to a version that
uses digital signature confirmation, you cannot downgrade to an earlier firmware
version that did not use digital signature authentication.

Remote display (RMD) upgrade behavior

Your meter’s remote display will upgrade as soon as the upgrade file is put in the
remote display upgrade folder on your meter’s internal FTP site. It is deleted as
part of the upgrade process.
NOTE: If your meter’s remote display loses power during firmware upload, the
display will revert to its original firmware and you will have to reload the
firmware file.

7EN02-0374-01 101
PowerLogic™ ION7400 series Maintenance

The results of your remote display firmware upgrade are stored in your meter’s
event log. Detailed information about your remote display, such as serial number
and firmware version is provided in the Factory module.
See the ION Reference, available from www.schneider-electric.com, for more
information about the Factory module.

Option module(s) upgrade behavior

To upgrade option modules, you must load the upgrade file into the appropriate
folder on the meter’s internal FTP site. The upgrade is triggered by either a power
cycle or option module reset. After the upgrade is performed, the upgrade file is
deleted from the meter’s internal FTP site before the option module is reset to run
the new firmware. The option module firmware will not upgrade if more than one
upgrade file is in the folder. The upgrade file must be the correct file type and
match the type of module being upgraded.
All option modules do not perform their regular functions during firmware upgrade.
If more than one option module is being upgraded, the firmware on the option
module closest to the meter is done first, then the next closest, proceeding to the
furthest module from the meter base requiring upgrading. A single option module
firmware upgrade should not take more than five minutes.
The option module upgrade results are stored in your meter’s event log. Detailed
information about the option module, such as serial number and firmware version
is provided in the Factory module. Information about the option module type and
details of the option module’s state is provided in the Diagnostics module.
See the ION Reference, available from www.schneider-electric.com, for more
information about the Factory and Diagnostic modules.

Loading meter firmware using ION Setup

You can load firmware onto your meter using ION Setup.
You can download firmware for your meter from www.schneider-electric.com.
You must load a meter template as part of the firmware upgrade process. You can
save your meter’s existing template by navigating to Template > Save to PC in the
ION Setup Assistant and clicking Save to save your meter’s template as a .DCF
file. You can also use a template that you have saved from another meter of the
same type, or download a factory template from www.schneider-electric.com.
Ensure that you record your meter’s user and password information in a secure
location before upgrading the meter’s firmware. If your meter’s user and password
information is lost, you must return the meter for factory reconfiguration, which
resets your meter to its factory defaults and destroys all logged data.
Any digital and analog outputs associated with your device may change state
during a firmware upgrade.

Loading firmware or template onto your meter clears the meter’s recorded data.

Test mode
Test mode is typically used for verifying meter functions.
The meter is usually reading data from a test power supply while function
verification is performed.
The values shown in the test mode display screens represent different
accumulators than those shown in norm or alt mode (although they perform some
of the same basic measurements). The test mode display values are for accuracy
checking purposes; they only accumulate while the meter is in test mode.
You can create custom test mode screens and modify the existing test mode
screens.
NOTE: You cannot place revenue-locked meters into test mode.
Several things to note about test mode:
• All of the billing quantities that are recorded when the meter is in Normal mode
stop accumulating when the meter is switched to test mode – the data is sent
to special test mode registers instead.
• The values accumulated in these test registers are displayed on the test mode
displays and in ION Setup.
• The regular normal mode billing registers are unaffected while the meter is in
test mode; accumulation of this data continues as soon as you exit test mode.
• All test registers are reset to zero when you exit test mode.

number and vendor name. You can use ION Setup in advanced mode to view the
contents of the Factory module’s setup registers. Similarly, you can use Modbus
commands to read the Modbus registers mapped to the corresponding Factory
module’s registers.
NOTE: Not all ION device setup registers are mapped to Modbus registers by
default.
Other device-specific details, such as Product Code, are not stored in the Factory
module. Product Code (also known as Modbus Product ID) is a number that the
manufacturer assigned to a product to uniquely identify it, for use by systems that
specifically require this information. You can use the device’s Modbus map and
Modbus commands to read the Modbus Product ID.
The ION Reference describes the Factory module in detail. You can download the
ION Reference and your device’s Modbus map from www.schneider-electric.com.

Troubleshooting
Technical assistance
Visit www.schneider-electric.com for support and assistance technical problems
with the meter.
Make sure you include your meter’s model, serial number and firmware version in
your email or have it readily available if calling Technical Support.

Option module troubleshooting

Your meter’s option modules operate sequentially; if one module is non-functional
all downstream modules may be affected.
If your meter cannot communicate with an option module, by default it cycles
power to that module and all downstream modules, making multiple attempts to
communicate. After the maximum number of communication attempts has been
exceeded the meter will remove power to that module and all downstream
modules.
When troubleshooting option modules, attach each option module directly to the
meter and verify its operation. If each option module operates when directly
connected, use combinations of modules or known good modules to help identify
the issue.
Events related to option module initialization and operation are stored in your
meter’s onboard event log. Perform an option bus reset to restart the option bus
and re-initialize the option modules attached to your meter.
Information about your option module’s type, serial number, firmware version and
present status is available in the Factory and Diagnostics modules.
See the ION Reference, available from www.schneider-electric.com, for more
information about the Factory and Diagnostics modules.

PowerLogic™ ION7400 series Logging

Logging
Logging overview
The meter is equipped with data recorders, waveform recorders and event logs
that enable you to log and monitor various metering functions and features.
Your meter has a number of onboard default logs (also called data recorders) that
are used to store data related to:
• Power quality and compliance
• Trending and forecasting
• Energy/revenue metering
• Meter events
Your meter also logs voltage and current waveform data when a sag or swell is
detected. You must enter your power system’s nominal values and configure your
meter so that it can identify sags and swells; and you can enable current waveform
recording if it is required for your system. You can configure your meter’s setpoint
learning feature to learn your power system’s normal operating values and use that
information to help identify voltage sags and swells.
Logged data can be retrieved by energy management software.

Related Topics
• Minimum configuration requirements for basic metering

Data logging overview

Your meter has data logging capabilities, including a special type of data log which
is an event log, which logs prioritized events.
Data logs are recorded by your meter and stored in the meter’s memory inside
configurable data logs. Your meter’s data logs are retained if the meter loses
power.
Logged data can be used by energy management software. Logs can be
configured to either overwrite the oldest data when full (circular), or to stop writing
data to the log when the number of logged records reaches the maximum log
depth (stop-when-full).
Your meter ships with a comprehensive data-logging configuration consisting of
data logs set up to record values at specific intervals or on conditions. Your meter’s
default data logging configuration should be sufficient for most applications, but
you can also reconfigure existing logs or create new logs for custom applications if
needed.
Your meter can also be configured to email data log information.
NOTE: Adding or deleting data logs or their parameters outside of the ION
Setup Assistant should only be undertaken by those with an advanced
understanding of ION architecture and their meter’s template.
See the Internal email client feature technical note, available from
www.schneider-electric.com, for instructions on how to configure your meter to
email logged data.
See the ION Reference, available from www.schneider-electric.com, for more
information about ION architecture and ION modules.

Event log overview

Your meter records events produced by the meter’s ION modules or external meter
events.

120 7EN02-0374-01
Logging PowerLogic™ ION7400 series

Meter events, such as meter configuration or changes to I/O state, have priority
values associated with them, so you can control what events are logged. Each
event has a priority based on its type and severity, and for most events you can
configure the priority. The event log records the date and time of the event, along
with relevant details about the event.
Your meter’s event log can be viewed through the meter’s display and ION Setup.
Event log data example:

NOTE: This example is representative only, and your meter’s event log may
appear different than shown.
See the ION Reference, available from www.schneider-electric.com, for more
information about the Event Log Controller module and other ION modules.

Related Topics
• Data viewing using your meter’s display

User triggered event log entries

The Event Log includes an association between security-related events and the
username that was logged in to the meter during the event.
When a user produces an event, such as a reset, successful or unsuccessful login
attempts, user lockout or setup change, it is written to the event log. Events
created in standard security through the meter’s display have the username
USER0. Events created in advanced security through the display or ION Setup are
associated with the username that was logged into the meter (USER1 - USER50).

Assigning a designated reader for event log notification

A user can be assigned the role of designated reader for the event log.
When the Designated Reader is configured, an entry in the event log is considered
unread until it has been reviewed or backed up to external storage by the
designated reader. When the designated reader is informed that the event log is
nearly full, an event log review or backup strategy can be implemented before
older entries are overwritten. This feature can assist in ensuring that event log
entries are not overwritten before they can be reviewed. Use ION Setup to select a
user to be the designated reader.

1. Open advanced configuration mode for your meter. See the ION Setup Help
for instructions.
2. Open the EventLogCtl Modules folder and double click EventLogCtl.
3. Enter login credentials as necessary.
4. Click the Setup Registers tab
5. Select Designated Reader and click Edit.

7EN02-0374-01 121
PowerLogic™ ION7400 series Logging

6. Set Designated Reader to the user that reviews the event log (USER0 -
USER50) and click OK.

Syslog overview
Syslog uses the User Datagram Protocol (UDP) to transport event log information
from the meter directly to a centralized syslog server.
The syslog server can receive logs from multiple devices, including meters, then
store and filter the log information as needed. You can use ION Setup to modify the
syslog network settings for your device. Syslog is a useful feature to help maintain
meter log information for extended periods of time.
NOTE: Ethernet is required to use the syslog feature.
Syslog is an open standard allowing you to use any one of a number of syslog
server applications currently available. The decision regarding which syslog server
solution to use can be based on budget and your technical requirements. See the
individual syslog server’s documentation for more information.

Configuring Syslog network settings using ION Setup

You can configure your syslog settings using ION Setup.

1. Open the Setup Assistant for your meter. See the ION Setup Help for
instructions.
2. Select Communications > Advanced Ethernet and click the SysLog tab.
3. Select Enable Syslog and click Edit.
4. Select Yes to enable the syslog server feature or select No to disable it.
5. Click OK.
6. Select Syslog Server and click Edit.
7. Enter the IPv4 address or an IPv6 address for the syslog server.
You must enter the IP address for the syslog server, not the server’s fully-
qualified domain name.
8. Click OK.
9. Verify that the Syslog server is receiving log information from the meter.
NOTE: If the Enable Syslog register is enabled but the Syslog Server
register does not contain an IP address, an event is generated in the event
log to indicate that syslog is enabled with no server IP.

Waveform recording overview

Your meter is able to record voltage and current waveform information.
Waveform information is used to help identify power system disturbances, which
are an increasing concern for industrial plants, hospitals, data centers and other
facilities where the equipment is sensitive to voltage or current sags, swells, and
momentary interruptions. Waveform information is also used to help ensure
compliance with power quality standards.
In addition to measuring and recording numerical values for voltage and current,
your meter can also capture the sinusoidal waveform data. The current and voltage
waveform data provides additional information for analysis of the system’s power
quality or a power quality event.
You can manually trigger waveform recordings or configure them to trigger
automatically when there is a power quality or power system event. For waveform
recording to trigger automatically, you must enter your system’s nominal (normal)
voltage and current values, and then the amount of deviation from the nominal
required to trigger waveform recording.

Waveform data storage format

Your meter’s waveform data storage format is defined by:
• Cycles: the number of cycles (based on your power system’s frequency)
included in the waveform (its duration).
• Samples: samples per cycle, which is the number of waveform data points
collected in each cycle.
This gives you the option to record a lot of information for a very short duration or
less information over a longer duration. You can also configure a delay in starting
waveform recording which allows you to record pre- and post-event data.

Types of waveform data

You can use your meter to detect ITI (CBEMA) - type disturbances, and can
determine information regarding the magnitude and duration of each disturbance.
This information can be used by your energy management system to plot the
disturbance on a CBEMA curve.
COMTRADE waveform data is available from your meter.
NOTE: If you are generating COMTRADE waveform information, the
associated waveform recorders cannot be modified unless COMTRADE is
disabled. If the waveform recorders are not configured identically, COMTRADE
waveform information will not be generated.

Key terms

Term Definition

COMTRADE COMmon format for TRAnsient Data Exchange (COMTRADE) is a common

format for waveform data.
ITI (CBEMA) A curve that graphically describes an AC input voltage envelope which can be
typically tolerated by information technology equipment. Meter waveform
information is plotted on this curve to help evaluate power quality.

Nominal The normal or usual parameter value. For example, the nominal voltage for
many power systems is 120 V.

Sag A power event where the voltage or current drops below the nominal value.

Swell A power event where the voltage or current rises above the nominal value.

See the ION Reference, available from www.schneider-electric.com, for more

information on the Waveform Recorder module and its settings.

Configuring sag/swell logging and waveform recording using ION Setup

You can configure your meter to record sag/swell data and to capture waveforms
when it experiences a sag or swell event, and to export the waveform data to
COMTRADE files.
NOTE: For waveform recording to trigger automatically, enter your system’s
nominal (normal) voltage and current values and the amount of deviation from
the nominal that is considered a sag or a swell using the Alarming screen.
Changing your meter’s waveform recording configuration clears your meter’s
existing waveform records, including its COMTRADE files.

Logging PowerLogic™ ION7400 series

Default event log configuration

Your meter logs all configuration changes, meter access events, and power system
events.
You can configure certain features, such as the digital inputs, so an event is logged
when the feature changes state (for example, the digital input changes from off to
on).
Your meter’s event log might be used by other components of your power
monitoring system. Do not change the default event log configuration unless you
understand the impact of the change on the power monitoring system components
and the data they use and on your meter’s memory.
Changing the default event log configuration should only be undertaken by those
with an advanced understanding of ION architecture and their meter’s template.
The event log is controlled by the Event Log Controller module, which allows you to
set a priority cutoff for event logging. Events with a priority number greater than the
cutoff value are logged, and events with lower priorities are discarded. By default,
this value is set so that all relevant events are recorded in the meter’s event log.
Event priority values range from 0 to 255 with a typical cutoff value of 5.
NOTE: Alarms are generated by events from certain ION modules. The alarm
level is determined by the priority of the associated event. To disable the alarm
but still record the associated event, set the alarm priority to Info Only. To
disable the alarm and the event, set the alarm priority to None.
See the ION Reference, available from www.schneider-electric.com, for more
information about the Event Log Controller module and event priorities for specific
ION modules.

Default waveform recording configuration

Your meter’s waveform recording operates once your nominal values are
configured.
Your meter has the following default waveform recorders:

Waveform recorder Description

Wfm Rc V1-Sg/Sw V1 voltage waveforms recorded during a defined sag or swell event.

Wfm Rc V2-Sg/Sw V2 voltage waveforms recorded during a defined sag or swell event.

Wfm Rc V3-Sg/Sw V3 voltage waveforms recorded during a defined sag or swell event.

Wfm Rc I1-Sg/Sw I1 current waveforms recorded during a defined sag or swell event.

Wfm Rc I2-Sg/Sw I2 current waveforms recorded during a defined sag or swell event.

Wfm Rc I3-Sg/Sw I3 current waveforms recorded during a defined sag or swell event.

Advanced log setup and memory optimization

You can configure your meter’s logs to help ensure the integrity of critical data and
to optimize the meter’s memory usage.
Before you configure your meter’s logs, it is important to understand how logging
functions and how the settings work together.
NOTE: Configuring your meter’s logs requires an in-depth understanding of the
meter’s memory, how the logs function and the data you are capturing.

7EN02-0374-01 129
PowerLogic™ ION7400 series Logging

Viewing log configuration and memory usage information

You can use ION Setup to view log settings and memory usage information for
your meter’s default logs.
This information can help you understand your log usage and how to optimize your
logging configuration for your situation.

1. Start ION Setup.

2. Open the Setup Assistant for your meter.
3. Navigate to the Logging > Memory screen.
The Status tab:
• lists the default logs, their interval (Duration) and depth (Records), if
applicable, and the percentage of available memory used by the log.
• provides information on how much of the meter’s memory is used for
system tasks in the System Resources list item.
• displays the total meter memory and the percentage of memory in use
versus memory available.

Log depth configuration

You can change the number of records (depth) stored in the log.
Use ION Setup to change the maximum number of records (depth) stored in the
log in the meter’s long-term memory.
Data logs and circular-format waveform recorders have a minimum depth of 2
records. The maximum depth is dependent on your meter’s memory and the
configuration of your other logs.

Log interval configuration

You can configure the logging interval, which is how frequently records are logged.
For example, a 15-minute interval results in records being logged at 1:00, 1:15,
1:30, 1:45, and so on
You can change the logging intervals for most logs using the ION Setup Assistant
Logging > Memory screen.
Changing the interval for other logs (for example, logs that are related to standards
or triggered by disturbances) is an advanced procedure that involves using the
Advanced mode of ION Setup to modify settings in the module that is linked to the
log’s Record input. See the ION Setup help and the ION Reference for more
information.
Programming your meter to write to any data recorder at continuous intervals
shorter than 60 seconds (heavy logging configuration) can cause loss of data in
the event of a power failure.

NOTICE
DATA LOSS
Use an uninterruptible power supply (UPS) if you program your meter for heavy
logging.
Failure to follow these instructions can result in data loss.

Log mode configuration

You can configure the log record mode, or how the log behaves when full.

130 7EN02-0374-01
Logging PowerLogic™ ION7400 series

Changing how the log records information (circular or stop-when-full) is an

advanced procedure that requires changing the RecordMode setup register in the
Data Recorder and Waveform Recorder modules.

x
A. Circular (FIFO) logging mode: when the log is full, a new record overwrites the oldest record
B. Stop-when-full logging mode: when the log is full, any new records are not logged

Log buffer configuration

The log buffer depth is the maximum number of records that can be stored in the
meter’s short-term memory (RAM) for a particular log.
After records are captured in the log buffer in the meter’s short-term memory, they
are moved to the long-term memory. Because of inherent differences between
short-term (volatile) and long-term (non-volatile) memory, records can be added
more quickly to the short-term memory than they can be copied to long-term
memory.
The logs in the default logging framework have their log buffer depths pre-
configured to a value suitable for most applications. But you can configure the log
buffer depth for your applications, if required (for example, to help ensure the
continuity of critical data in high-speed logging scenarios or to optimize usage of
your meter’s memory for your particular logging configuration).
If you are logging data at high speeds, it is important to review your logging needs,
and find the right balance between data retention and memory optimization for
your particular situation.
NOTE: If you get a message that you do not have sufficient memory when you
try to create a new log or change the configuration of an existing log, you may
need to reduce the log buffer depths of other logs in order to make memory
available for the new log.

Fully buffered logs

In a fully buffered log, the log buffer depth is equal to the log depth, which results in
the log being replicated (or copied) in its entirety from short-term to long-term
memory.
You may want to use this configuration if you are logging critical data (for example,
revenue logs) or logging data at frequent intervals (for example, intervals less than
60 seconds). However, it is important to note that this configuration uses the most
short-term memory, or RAM (the meter has a maximum 10 MB of RAM available
for the log buffer depth).

Partially buffered logs

In a partially buffered log, the log buffer depth is set to a value less than the log
depth, which results in records being moved from the log buffer to long-term
memory, instead of copied.
This enables you to use more memory for a log than you could if it were fully
buffered (for example, you could have a log that uses 80 MB of memory that would
have a maximum size of 10 MB if it were fully buffered).

7EN02-0374-01 131
PowerLogic™ ION7400 series Logging

You may want to use this configuration for logs with intervals greater than 60
seconds or with less critical data. Because the records are moved to long-term
memory rather than replicated, this configuration uses less of the meter’s short-
term memory, or RAM, in a log that is otherwise configured the same. This allows
you to make more RAM available for other logs with a higher logging frequency or
more critical data.
However, depending on your configuration, there may be instances where the log
buffer fills up faster than it can move records to long-term memory. In this case,
you may lose records and see gaps in your data.
NOTE: The Insert Outage Records functionality does not work if the data
recorder is configured as partially buffered. In order to use this functionality,
you must configure the data recorder to be fully buffered. See the Data
Recorder module description in the ION Reference, available for download
from www.schneider-electric.com, for more information on Insert Outage
Records functionality.

Example: fully buffered log records replicated from short-term to long-term

memory

A. Log buffer
B. Long-term memory
C. Total available space
8:45:30.000 8:45:30.000 in the log buffer (for

9:03:30.000 9:03:30.000
9:04:30.000 9:04:30.000

In this example, the log buffer equals the log depth and all the records are
replicated in both the short-term memory and the long-term memory.

Example: Partially buffered log records moved from short-term memory to

long-term memory

A. Log buffer
B. Long-term memory
C. Total available space
in the log buffer (for
example, 20 records)

In this example, the buffer depth equals 20. The first record has already moved to
the long-term memory, making room in the log buffer for the new records (including
the newest record, in gray).

Example: Resulting gaps in data when a partially buffered log is full

However, depending on your configuration, there may be instances where the log
buffer fills up faster than it can move records to long-term memory. In this case,
you may lose records and see gaps in your data.

In the graphic on the left, the log buffer (A) is full, and the oldest record has not
been moved to the long-term memory yet. This means that the new record (C) is
not logged, and is permanently lost. In the graphic on the right, the oldest record
(D) has been moved to long-term memory, making space in the buffer. The new
record at the next interval (E) is logged but there is a gap in the data for the lost
record (C).

Changing log interval and depth settings using ION Setup

You can configure log intervals, log depths and buffer depths to optimize your
memory usage.
Before you begin, make sure you understand:
• the structure of the meter’s logging framework
• the meter’s existing logging configuration
• your data logging requirements
Changing your meter’s log configuration deletes all existing records from that log.

NOTICE
DATA LOSS
Ensure that all important data has been recorded before configuring a log.
Failure to follow these instructions can result in data loss.

The default log settings are designed to meet the needs of most users.
This procedure provides the steps for configuring settings for a subset of data logs
using the ION Setup Assistant. Configuring these settings for custom logs, and
logs not listed in the Logging > Memory screen, is an advanced procedure; see
the ION Setup help for more information.

1. Start ION Setup.

2. Open the Setup Assistant for your meter.
3. Navigate to the Logging > Memory screen.

7EN02-0374-01 133
PowerLogic™ ION7400 series Logging

4. Select the log you want to edit and click Edit.

5. Set the log depth and log interval as required for your logging needs.
• Log Interval: you can change the interval units to seconds, minutes,
hours or days.
• Log Depth: You can set the depth in time (seconds, hours, days, etc.) or
the number of records.
NOTE: For some log types, you only set the log depth (for example,
waveform recorders).
Log Memory shows the estimated impact of the changes on the total size of
the log and Log Storage displays the estimated available log memory on the
meter.
NOTE: If you receive a message stating that there is not enough memory
when you change a log’s configuration, check the configuration of your
meter’s other logs. You may not have enough RAM, or short-term memory,
to allow for the new configuration. You may need to use ION Setup
Advanced mode to check the detailed configuration of your logs.
6. Click Finish.
In some case, you may see a Next button instead of Finish. In this case, the
next screen allows you to configure the buffer depth for the log. The screen
displays the overall log depth and a field for setting the log buffer depth. It also
shows the impact of the Buffer Depth setting to your meter’s short-term
memory (RAM).

Data log memory calculations

The amount of memory required to store data and event logs depends on the
number of parameters being logged and the frequency with which these
parameters are logged.
You can use the following calculation to estimate the approximate amount of
memory required for a data log:
Memory consumption for each record (in Bytes) = [(number of parameters x 5) + 8]
For example, a data log recording three parameters consumes 23 Bytes of data. If
the data is recorded every 15 minutes for 35 days, the data log requires
approximately 80 kiloBytes of logging memory.
See the ION Setup online help for more information about the logging memory
allocations and other meter logging memory information displayed by the ION
Setup Assistant.

Waveform record memory calculations

The meter can simultaneously capture waveforms triggered by events on all
channels to a maximum of 96 cycles for each waveform record.
You can use the following calculation to estimate the approximate amount of
memory required for a waveform record:
Memory consumption for each waveform (in Bytes) = [2 x number of samples per
cycle + 12] x [number of cycles in waveform x 2] + 32.
A single waveform record requires approximately 8 kB of memory.
See the ION Setup online help for more information about the logging memory
allocations and other meter logging memory information displayed by the ION
Setup Assistant.

I/O option modules

I/O option modules provide increased digital and analog input/output (I/O)
capabilities for your meter.

WARNING
UNINTENDED OPERATION
Do not use the meter for critical control or protection applications where human
or equipment safety relies on the operation of the control circuit.
Failure to follow these instructions can result in death, serious injury or
equipment damage.

These I/O modules can be used to monitor the status of breakers, control analog or
digital transducers, or receive signals that can be interpreted to provide WAGES
data for your energy system. For applications requiring high accuracy, such as
energy pulsing to verify accuracy, the digital output on the meter base is
recommended.
Your meter’s digital and analog outputs may change state during a firmware
upgrade. Option modules are offline during an option module firmware upgrade;
they will not communicate to the meter and the outputs may change state during
the upgrade process.
Your meter’s analog I/O option modules can measure and output either low voltage
or current using standard analog transducers such as 4 - 20 mA current
transducers.

Analog inputs
Analog input applications
You can use an analog input to monitor an analog flowmeter to monitor how much
water flows through a pipe.
For analog input operation, your meter takes an analog input signal and provides
the resulting scaled value.
Your meter’s analog I/O option modules can measure either low voltage or current
using standard analog transducers such as 4 - 20 mA current transducers.

Analog input voltage and current mode

You can set the analog input’s mode for voltage or current sensing.
In current mode, the analog inputs have a low input resistance while the meter is
powered on, and a high input resistance when the meter is powered off. In voltage
mode, the analog inputs have a high input resistance regardless of whether the
meter is powered or not.
NOTE: When unpowered, your meter’s analog inputs act like they are in
voltage mode (high input resistance).
When connected to a current output transducer, this high resistance can create a
high voltage. Standard (i.e., 4 to 20 mA) current transducers have open circuit
protection and are able to handle a high input resistance; however, if non-standard
transducers are used high voltages may be generated. Your meter’s analog input
has circuitry to limit this voltage, but it may not be sufficient with a very high-power
current source.

NOTICE
EQUIPMENT DAMAGE
• Ensure the analog input is configured for the correct voltage or current mode
before connecting or activating the current transducer.
• Do not exceed the device’s ratings for maximum limits.
Failure to follow these instructions will result in equipment damage.

Analog input behavior

Analog inputs may show a value below zero scale if an open circuit is detected on
the input port.

Analog input zero scale and full scale values

Configure your analog input’s zero and full scale values.
In most cases the output range of the sensor feeding the analog input matches the
hardware limits of your meter’s analog input port. In that case, the analog input’s
zero scale and full scale values are the same as the sensor’s represented range.
For example:

Analog sensor Meter’s analog input Analog input values

0 - 50 psi represented by a 4 - 20 mA analog input range Full scale = 50 (psi)

4 - 20 mA signal Zero scale = 0 (psi)

If the sensor’s output range does not match your meter’s hardware limits, you must
calculate the full scale and/or zero scale values by analyzing the system.
See the ION Reference, available from www.schneider-electric.com, for detailed
information about the Analog Input module and full scale and zero scale
calculations.

Configuring option module analog inputs using ION Setup

You can configure analog inputs using ION Setup.
Analog inputs are available on the optional I/O modules you can connect to the
base of your meter.

Analog outputs
Analog output applications
You can use an analog output to send a signal to an analog-controlled valve to
modify a water pipe’s valve position in order to change the flow rate.
For analog output operation, your meter takes an input value and scales it to the
appropriate signal value to send out the physical analog output port.
Your meter’s analog I/O option modules can output either low voltage or current
using standard analog transducers such as 4 - 20 mA current transducers.

Analog output behavior

Your meter’s analog output, once configured, outputs voltage or current signals. If
your meter’s analog output source becomes unavailable (N/A) the analog output
level should go to zero (0 V / 0 mA) under most conditions.
When your meter is powered off or configured to send voltage, the meter registers
as a high impedance.
The electrical signal on the analog output is DC; make sure proper polarity is
observed when wiring external devices to the analog output ports.
An unexpected change of state of the analog outputs can result when the supply
power to the meter is interrupted, during an upgrade of the meter’s firmware or
framework or option module firmware or a during an option module reset.

Analog output zero scale and full scale values

Configure your analog output’s zero and full scale values.
In most cases your meter’s analog output range matches the range of the analog
sensors that your meter’s outputs are connected to. In that case, your meter’s

140 7EN02-0374-01
Inputs / outputs PowerLogic™ ION7400 series

analog output zero scale and full scale values are the maximum and minimum
values of the source driving your meter’s analog output. These values are used to
normalize the source value to a value between 0 and 1 which is applied to the
operating range of the analog output port to determine the analog output current or
voltage. For example:

Source value Analog output values Meter’s analog Analog sensor

output

0 to 120 kW range Full scale = 120 (kW) 4 - 20 mA range 4 - 20 mA range

100 kW Zero scale = 0 (kW) Output: 17.28 mA
Normalized: 0.83

If your meter’s analog output range does not match the range of the connected
analog sensor, you must calculate the full scale and zero scale values by analyzing
the system.
See the ION Reference, available from www.schneider-electric.com for detailed
information about the Analog Output module and full scale and zero scale

Digital inputs are typically used for monitoring the status of contacts, such as
status contacts on circuit breakers.
They can also be used for pulse counting or input metering applications, such as
WAGES (water, air, gas, electricity, steam) monitoring, or conditional energy
applications, or IRIG-B time synchronization.

IRIG-B time synchronization

You can use a digital input to synchronize the meter time to an IRIG-B time source.
You can connect an IRIG-B time source to one of meter’s digital inputs for IRIG-B
time synchronization; for improved accuracy use the digital inputs on the meter

WAGES monitoring
WAGES monitoring allows you to record and analyze all energy sources and
utilities usage.
Your energy system may use several different types of energy. For example, you
may consume steam or compressed air for industrial processes, electricity for
lights and computers, water for cooling and natural gas for heating. WAGES
monitoring collects the usage information from all these different energy sources to
enable a more complete energy analysis.
WAGES information can help you:
• Identify losses or inefficiencies.
• Modify demand to reduce costs.
• Optimize energy source usage.

WAGES example
This example shows WAGES monitoring for a water flow meter.

7EN02-0374-01 143
PowerLogic™ ION7400 series Inputs / outputs

You can connect your meter’s digital input to a transducer that sends a pulse for
every 15 kiloliters (4000 US Gal) of water. After configuring an input metering
channel and assigning it to the digital input, the meter is able to detect and record
the incoming pulses. An energy management system can then use the information
from the meter to perform WAGES analysis.

A Water flow meter (15 kL/pulse)

B Energy meter with digital input 1 assigned to input metering channel 1 and configured with unit
kL (kiloliters)

C Energy management system with WAGES analysis capabilities

Input metering
Your meter’s digital inputs can be used to count pulses from transducers and
convert the pulses to energy measurements.
Your meter’s input metering channels count pulses received from the digital inputs
assigned to that channel. The incoming pulses are used in calculating and
measuring consumption data (e.g., BTU, kWh, L, kg). Each channel must have the
following values configured to match the pulse data:
• Pulse Weight: the pulses per unit value.
• Unit Code: the unit of measure associated with the monitored value.
• Demand Code: for time-based values (such as kWh), this provides the
associated demand units (kW) for demand calculations; for other values (such
as kg), this can be configured to provide rate information (kg/h or kg/s).
• Mode: whether a pulse is based on a complete pulse or a transition.

For example, if each complete pulse represents 125 Wh, you can configure for Wh
pulsing as follows:
• Pulse Weight = pulses/Wh = 1/125 = 0.008
• Unit Code = Wh
• Demand Code = kW (this is automatically set)
• Mode = pulse
If you want to configure for kWh pulsing, you must adjust the pulse weight
calculation and unit code as follows:
• Pulse Weight = pulses/kWh = 1/0.125 = 8
• Unit Code = kWh

delivered (Wh Del) per pulse.

Pulse Width The minimum time in seconds between pulse transitions.

NOTE: There is a minimum 50% duty cycle on all pulses.

OutputMode Select the desired output mode:

• Pulse: the digital output sends a complete pulse when triggered.
• KYZ: the digital output makes a transition (off to on, or on to off) when
triggered.

Port Select an output port from the list. Only available output ports are shown
(ports that are not associated with another function).

(energy source) Pulsing normally indicates that the output port should be operating
ovrld normally.
Pulsing suspended indicates that the output port is not able to pulse quickly

Calculate your maximum kWh/pulse (pulse weight) value

To calculate the kWh/pulse (pulse weight) value, divide the highest kW value you
can expect by the required pulse rate.
Make sure the required pulse rate does not exceed the maximum pulse rate for the
digital output.
NOTE: To convert from kWh/pulse to pulse/kWh you must invert (take the
reciprocal) of the value. For example, 1.8 kWh/pulse becomes 0.556 pulse/
kWh.

Example pulse weight calculation

For a maximum load of 1600 kW and a pulse rate of 2 pulses per second, calculate
the kWh/pulse value as follows:
1. Convert 1600 kW load into kWh/second:
(1600 kW)*(1hr) = 1600 kWh
(1600 kWh)/(3600 sec) = (X kWh)/(1sec)
X = 0.444 kWh/sec
2. Calculate the kWh required per pulse:
(0.444 kWh/sec)/(2 pulses per second) = 0.222 kWh/pulse
3. Adjust for the KY giving one pulse per 2 transitions if necessary.
(0.222 kWh/pulse)/(2) = 0.111 kWh/pulse

Alarms and alerts

Alarms overview
An alarm is the meter’s means of notifying you when an alarm condition is
detected, such as an error or an event that falls outside of normal operating
conditions.
You can configure your meter to generate and display high, medium and low
priority alarms when predefined events are detected in the meter’s measured
values or operating states. Your meter also logs the alarm event information. Your
meter comes with many alarms. Some alarms are preconfigured, while others
need to be configured before your meter can generate alarms. Your meter’s default
alarms can be customized, as needed, such as changing the priority. You can
create custom alarms using the advanced features of your meter.

Alarm types
Your meter has four types of alarms.

Type Description

Setpoint Setpoint alarms define an alarm by comparing the actual value of a parameter
(standard) to a specified limit or range of values. These include measured voltage and
current values and calculated power quality values.
Some setpoint alarms use high-speed measurements for up to 1 millisecond
resolution.
Digital Digital alarms define an alarm condition based on a digital input’s on/off state.

Disturbance (sag/ Disturbance alarms define an alarm based on a measured sag or swell.
swell)

Unary Unary alarms are not configurable, and generate an alarm based on the meter’s
state, for example, the meter powering up.

Alarms have two states:

• Active: the meter detects the alarm condition is met.
• Historical: the alarm condition previously existed but the condition has since
returned to a non-alarm state.
See the ION reference, available from www.schneider-electric.com, for more
information about Setpoint, Digital Input and Sag/Swell modules.

Standard alarms
Standard alarms are setpoint-driven alarms monitor certain behaviors, events or
unwanted conditions in your electrical system.
Standard alarms have a detection rate equal to the 50/60 meter cycle, which is
nominally 1 second if the meter’s frequency setting is configured to match the
system frequency (50 or 60 Hz).
Many of the standard alarms are three-phase alarms. Alarm setpoints are
evaluated for each of the three phases individually, but the alarm is reported as a
single alarm. The alarm pickup occurs when the first phase exceeds the alarm
pickup magnitude for the pickup time delay. The alarm is active as long as any
phase remains in an alarm state. The alarm dropout occurs when the last phase
drops below the dropout magnitude for the dropout time delay.

Example of over and under setpoint (standard) alarm operation

The meter supports over and under setpoint conditions on standard alarms.

7EN02-0374-01 151
PowerLogic™ ION7400 series Alarms and alerts

A setpoint condition occurs when the magnitude of the signal being monitored
crosses the limit specified by the pickup setpoint setting and stays within that limit
for a minimum time period specified by the pickup time delay setting.
The setpoint condition ends when the magnitude of the signal being monitored
crosses the limit specified by dropout setpoint setting and stays within that limit for
a minimum time period specified by dropout time delay setting.

Over setpoint

When the value rises above the pickup setpoint setting and remains there long
enough to satisfy the pickup time delay period (ΔT1), the alarm condition is set to
ON. When the value falls below the dropout setpoint setting and remains there
long enough to satisfy the dropout time delay period (ΔT2), the alarm condition is
set to OFF.

operating a digital output. The meter also records maximum values (Max1, Max2)
before, during or after the alarm period.

Under setpoint

When the value falls below the pickup setpoint setting and remains there long
enough to satisfy the pickup time delay period (ΔT1), the alarm condition is set to
ON. When the value rises above the dropout setpoint setting and remains there
long enough to satisfy the dropout time delay period (ΔT2), the alarm condition is
set to OFF.

operating a digital output. The meter also records minimum values (Min1, Min2)
before, during or after the alarm period.

152 7EN02-0374-01
Alarms and alerts PowerLogic™ ION7400 series

Relative setpoint
The meter supports high-speed Relative Setpoint modules for capturing events
with half-cycle time intervals.
The meter’s Relative Setpoint modules behave similarly to the Setpoint modules,
except the pickup and dropout levels are set relative to the Nominal input source.
For more information on Relative Setpoint modules, download ION Reference at
www.schneider-electric.com.

Disturbance (sag/swell) alarms

These alarms are triggered by voltage and current disturbances.
You must configure nominal voltage and current for these alarms to function.
For voltage disturbances, enter the percentage deviation from the nominal that
defines a sag or swell.
For current disturbances, enter the percentage deviation from the nominal that
defines the pickup and dropout points for a current sag or a current swell.

Digital alarms
These alarms are triggered when the associated digital input changes state.
You can configure the alarm to be active when the digital input is on or off,
depending on the alarm’s purpose.
For example, if you used a digital input to monitor a breaker that is always
supposed to be on, you would set the alarm to be active when the breaker has
tripped.
NOTE: To stop a digital alarm from being displayed, set the alarm priority to
Info Only. Disabling (force off) the digital alarm off will disable all functions of
the associated digital input.
See the ION Reference, available from www.schneider-electric.com, for more
information about the Setpoint and Relative Setpoint module, Digital Input module,
Sag/Swell module and Disturbance Analyzer modules.

Alerting
An alert is an external notification produced by the meter to indicate changes, for
example, a change of state for a digital input, or a power quality event such as a
sag or swell.
Alerts are generated when a pulse or trigger that is configured to indicate the alert
condition activates. You can configure alerts to send notification emails or
messages to your energy management system through your meter’s existing
Ethernet communications connections. You can configure alert messages as a
simple text string or you can also include device information. You can configure the
alert’s priority so that alerts are also recorded in the meter’s event log.
You can configure multiple alerts on a single meter, each having different activation
triggers, messages and/or transmission types. For instance, you can have two
alerts, one generating an email, the other sending a message to your energy
management system, but using the same trigger conditions; or you can have two
alerts with different conditions that send two unique emails to two different email
addresses. You can also generate alerts based on triggers from devices connected
to your meter.
Creating alerts is an advanced feature that requires familiarity with ION
architecture and your power system and communications network. To create an
alert, you must configure the Alert module using a configuration tool. You must also
configure your device’s communications as needed to send the alerts, such as
configuring your meter’s SMTP settings and connecting it via Ethernet to an SMTP
mail server in order to send an alert by email.
Go to www.schneider-electric.com to see the ION meter alerts technical note for
detailed information on creating and configuring alerts, and the ION Reference for
detailed information about the Alert module and its operation.

Setpoint learning overview

Your meter can learn acceptable ranges or thresholds by monitoring normal
operating values to determine what constitutes a voltage sag or swell in order to
help identify high and low setpoints.
NOTE: To help your meter learn the most accurate values possible, it is
important that learning occur during a period of normal operation. Do not
schedule learning during a period of unusual operations in your system. Do not
modify your meter’s configuration during the learning period as it may stop the
learning process.
You can configure the meter so that learned values are applied automatically once
the learning period is complete or require that they are reviewed and manually

160 7EN02-0374-01
Alarms and alerts PowerLogic™ ION7400 series

applied. If a learned value is invalid, the learned values are not automatically
applied, but logged for review.
Setpoint learning can be used to identify the following values:

Feature Values
Setpoints (Alarms) High limit
Low limit
Sustain until ON
Sustain until OFF
Sag Voltage sag limit

Swell Voltage swell limit

Learning installation mode and learning duration

You can configure learning for manual or automatic mode.
There are two learning installation modes:
• Manual: the meter learns the applicable values but does not begin using the
learned values. The learned values are recorded for review, and you can
decide to use the learned values or adjust them as required before manually
implementing the learned values.
• Automatic: the meter learns the applicable values and begins using those
learned values automatically at the end of the learning period. If a learned
value is invalid, the meter does not apply the value, but the value is recorded
in the event log.
You can configure the maximum learning duration. The actual learning duration
may vary, depending on the stability of the system. If the system is stable for a
period equal to one quarter of the maximum learning duration, learning is
complete; otherwise, the learning period will be the maximum learning duration.

Example: Setpoint learning duration in a stable system

In this example, the learning duration is 30 days. When the system is stable for 7.5
days (one quarter of 30 days) learning is complete.

Power factor (PF)

Power factor (PF) is the ratio of real power (P) to apparent power (S).
Power factor is provided as a number between -1 and 1 or as a percentage from
-100% to 100%, where the sign is determined by the convention.
P
P F = ---
S

An ideal, purely resistive load has no reactive components, so its power factor is
one (PF = 1, or unity power factor). Inductive or capacitive loads introduce a
reactive power (Q) component to the circuit which causes the PF to become closer
to zero.

True PF and displacement PF

The meter supports true power factor and displacement power factor values:
• True power factor includes harmonic content.
• Displacement power factor only considers the fundamental frequency.
NOTE: Unless specified, the power factor displayed by the meter is true power
factor.

Apparent, active and reactive power (PQS)

Apparent power (S) is the capacity of your measured power system to provide
active (real power, P) and reactive power (Q).
A typical AC electrical system load has both resistive and reactive (inductive or
capacitive) components. Resistive loads consume real power (P). Reactive power
(Q) is either consumed (inductive loads) or generated (capacitive loads).

flows from the load to the power source.

Current phase shift from voltage

Electrical current can lag, lead, or be in phase with the AC voltage waveform, and
is typically associated with the type of load — inductive, capacitive or resistive.
For purely resistive loads, the current waveform is in phase with the voltage
waveform. For capacitive loads, current leads voltage. For inductive loads, current
lags voltage.
The following diagrams show how voltage and current waveforms shift based on
load type under ideal (laboratory) conditions.

Power demand
Power demand is a measure of average power consumption over a fixed time
interval.
NOTE: If not specified, references to “demand” are assumed to mean “power
demand.”
The meter measures instantaneous consumption and can calculate demand using
various methods.

Peak demand
Peak (or maximum) demand is the highest demand level recorded over the billing
period.
Power utilities generally bill commercial customers based on their peak usage
levels, called peak demand (in kW) and energy consumption (in kWh). Peak (or
maximum) demand is the highest demand level recorded over the billing period.
You can view peak demand values on your meter’s display.
Your meter calculates the average current demand and kW, kVAR and kVA
demand using sliding window demand methods. The meter supports coincident
demand values when a peak demand is detected.
Your meter’s default configuration is suitable for most applications, or you can
customize it for your specific application. You can configure the minimum time
between consecutive demand resets.
NOTE: If not specified, references to “demand” are assumed to mean “power
demand”.

Peak demand reset lockout

The demand reset lockout time sets the minimum time allowed between
consecutive demand resets; the meter ignores any attempts to reset demand that
occur within the lockout period.
The peak demand reset lockout period is user-configurable, with a default value of
25 days.
See the ION Setup online help for instructions on how to configure demand peak
and the demand reset lockout period on your meter.
See the ION Reference, available from www.schneider-electric.com, for detailed
information on how Sliding Window Demand modules measure and calculate
demand values.

Sliding window demand

To calculate demand values, your meter uses the sliding window averaging (or
rolling interval) method which divides the demand interval into a set number of
subintervals of specified duration.
The demand is measured electronically based on the average load level over the
most recent set of subintervals. Sliding window demand also provides predicted
demand values.

7EN02-0374-01 171
PowerLogic™ ION7400 series Measurements

Examples of sliding window demand

This example shows two different ways of configuring a 15-minute demand
interval:
• Single interval (also called block or timed block): the 15-minute demand
interval is defined as a single subinterval with a duration of 15 minutes.
• Sliding window (also called rolling block): the 15-minute demand interval is
defined as three subintervals with a duration of 5 minutes each. This method
offers better response time than a single interval.

WAGES example
This example shows WAGES monitoring for a water flow meter.
You can connect your meter’s digital input to a transducer that sends a pulse for
every 15 kiloliters (4000 US Gal) of water. After configuring an input metering
channel and assigning it to the digital input, the meter is able to detect and record
the incoming pulses. An energy management system can then use the information
from the meter to perform WAGES analysis.

Incremental energy
Incremental energy allows you to define a start time, end time, and the time interval
(increments) for incremental energy accumulation.
At the end of each interval, the energy accumulated during that period is stored. By
default, the meter only records the previous interval’s incremental energy and the
instantaneous energy accumulations in the active interval.
The first interval of incremental energy accumulation begins at the specified start
time. Incremental energy ends at the specified end time, which may result in a
truncated interval if the interval duration does not divide evenly into the overall
incremental energy duration (for example, an interval duration of three hours with
an overall duration of five hours truncates the last interval duration to two hours).
The latest value for the specified end time is midnight (24:00).
Your start time must be before the end time and after midnight, and the period over
which incremental energy is accumulated cannot include midnight. This is because
your meter’s start and end times are defined relative to midnight.

Start: 6 am, End: Incremental energy accumulates from 6 am to midnight in intervals of 3 hours.
12 am, interval: 3
hrs
Start: 6 am, End: Incremental energy will not function. End time must be after start time and
2 am, interval: 3 before or equal to midnight.
hrs

Incremental energy helps provide information for analyzing energy and power
usage against present or future utility rates, and is useful for comparing different
time-of-use rate structures.
When configuring incremental energy, shorter incremental energy periods provide
more granular data which can make the data easier to use for comparison
purposes.

Incremental energy example

• Start time: 8 am or 08:00
• End time: 12 am or 24:00
• Interval: 420 minutes (7 hours)

A. First interval (08:00 to 15:00)

B. Second interval (15:00 to 22:00)
C. Third interval (22:00 to 24:00)

7EN02-0374-01 173
PowerLogic™ ION7400 series Measurements

The first incremental energy interval is from 8 am (start time) to 3 pm, and is seven
hours long. The second incremental energy interval is from 3 pm to 10 pm, and is
also seven hours long. The third interval is from 10 pm to 12 am, and is only 2
hours long because 12 am is the specified end time. These intervals repeat every
24 hours until the configuration is changed or incremental energy feature is
disabled.

12:00 am
The end time must be after the start time and be less
than or equal to 12 am (midnight).

Interval duration Configurable The increment period for the incremental energy
duration.

Conditional energy
Conditional energy allows you to define an accumulation period for real and
reactive energy using one of your meter’s digital inputs.
You can use conditional energy to track four-quadrant accumulated energy during
a specific period; for example you may want to track accumulated energy values
during a particular process controlled using a programmable logic controller (PLC).
Conditional energy is accumulated until it is reset. The conditional energy reset
date and time information is stored in the meter’s event log.

Trending and forecasting overview

Trending and forecasting is a feature on your device that predicts the next set of
measured or calculated data by plotting and analyzing trends in historical data.
Trending and forecasting data is a useful tool to help analyze changes in load and
power quality and forecasting values such as demand. For your meter’s trending
and forecasting feature to work, you only need to give the meter time to
accumulate data.

Trending and forecasting implementation

Data used for trending and forecasting can be logged for specific intervals.
Data used is logged for the following intervals:
• Every hour for the last 24 hours
• Every day for the last month
• Every week for the last 8 weeks
• Every month for the last 12 months
The following parameters are configured for trending and forecasting using ION

Power quality
Power quality overview
Your meter measures voltage and current harmonics, and calculates several
harmonic distortion values as well as K-factor and crest factor values.
You must configure your meter with nominal values for voltage, current and
frequency for the power system being monitored in order for the meter to perform
power quality calculations. Your meter also creates a phasor diagram, including
numeric values for magnitude and angle, to represent your power system.

Sag/swell overview
Your meter monitors your power system’s voltage and current for sags and swells
(INCITS (CBEMA) Type 2 and Type 3 disturbances); it then reports the
disturbance’s magnitude and duration.
You can manually enter the limits (criteria) used by the meter to identify a sag or
swell, or you can have your meter learn sag/swell limits by monitoring your power
system.

Harmonics overview
Harmonics information is valuable for power quality analysis, determining properly
rated transformers, maintenance and troubleshooting.
Harmonics are integer multiples of the fundamental frequency of the power
system. Harmonics information is required for compliance to system power quality
standards such as EN50160 and meter power quality standards such as IEC
61000-4-30.
Harmonics measurements include per-phase magnitudes and angles (relative to
the fundamental frequency of the phase A voltage) for the fundamental and higher
harmonics relative to the fundamental frequency. The meter’s power system
setting defines which phases are present and determines how line-to-line or line-
to-neutral voltage harmonics and current harmonics are calculated.
Harmonics are used to identify whether the supplied system power meets required
power quality standards, or if non-linear loads are affecting your power system.
Power system harmonics can cause current flow on the neutral conductor, and
damage to equipment such as increased heating in electric motors. Power
conditioners or harmonic filters can be used to minimize unwanted harmonics.

Voltage crest factor

Crest factor is the ratio of peak to RMS voltage values.
For a pure sinusoidal waveform, crest factor is equal to 1.414. The meter uses the
following equation to calculate crest factor:

C = Crest factor
Vpeak
C= Vpeak = Voltage peak
VRMS
VRMS = Voltage RMS

Crest factor current

Crest factor is the ratio of peak to RMS current values.
For a pure sinusoidal waveform, crest factor is equal to 1.414. The meter uses the
following equation to calculate crest factor:

C = Crest factor
Ip e a k
Cre s t fa ctor = ------------- Ipeak = Current peak
IR MS
IRMS = Current RMS

K-factor
K-factor relates the heating effect of a distorted current in a transformer to a
sinusoidal current with the same RMS magnitude — it describes a transformer’s
ability to serve non-linear loads without exceeding rated temperature rise limits.
The K-factor is equal to the sum of the squares of the harmonic currents multiplied
by the squares of the harmonic order. The meter uses the following equation to
calculate K-factor:
h
∑ (Ih x h ) 2 2

n=1
K=
h 2
∑ Ih
n=1
Where K is the K-factor, h is the harmonic order and Ih is the true RMS current of
harmonic order h.

Harmonic content calculations

Harmonic content (HC) is equal to the RMS value of all the non-fundamental
harmonic components in one phase of the power system.

178 7EN02-0374-01
Power quality PowerLogic™ ION7400 series

The meter uses the following equation to calculate HC:

HC = (H 2 )2 + (H 3 )2 + (H 4 )2 ...

TDD calculations
TDD (total demand distortion) evaluates the harmonic currents between an end
user and a power source.
The harmonic values are based on a point of common coupling (PCC), which is a
common point where each user receives power from the power source.
The meter uses the following equation to calculate TDD:

TDD = ( (HCIA) 2 + (HCIB) 2 + (HCIC) 2 ) / (ILoad) x 100

Where ILoad is equal to the maximum demand load on the power system.

thd and TDD

Your meter can be configured to provide thd (total harmonic distortion using the
total RMS value for the content rather than the fundamental content) and TDD
(total demand distortion, the harmonic current distortion against the maximum
demand of the electrical system.
thd = HC / RMS *100%
TDD = HC / DemandMax *100%
This is an advanced procedure that should only be performed by users with an
advanced knowledge of power quality, ION architecture, and the power system
being monitored.
See the ION Reference, available from www.schneider-electric.com, for details
about the Harmonics Measurement module.

Phasors
Phasors are used to represent the voltage and current relative magnitude and
angles.
The length of the lines in the phasor diagram represent the relative magnitude of
the voltages with respect to the other phase voltages, and the currents with respect
to the other phase currents. All angles are measured with respect to the Va/V1
phase. The Va/V1 phasor is fixed to the right-hand horizontal axis (positive x-axis).
Positive angles are measured counterclockwise.
Numeric values are provided for the magnitude and relative angle for each voltage
and current phase.
Phasor information can be used to troubleshoot incorrect connections on the
meter’s voltage and current inputs (for example, switched phase wiring or polarity
errors), if you know how the phasors should be oriented for your power system.

Disturbance direction detection overview

Your meter has disturbance direction detection capabilities to help you determine
the location of a power system disturbance.
When a disturbance occurs, the meter analyzes the disturbance information to
determine the direction of the disturbance relative to the meter. This analysis
includes a confidence level indicating the level of certainty that the disturbance is in
the determined direction, and is stored in your meter’s event log.

7EN02-0374-01 179
PowerLogic™ ION7400 series Power quality

Disturbance direction detection is enabled on your meter by default and does not
require any additional configuration beyond setting the nominal voltage and
nominal frequency.
Disturbance direction detection can help locate the source of a disturbance when
used in a system of disturbance direction detection devices, as shown in the
diagram below.

COMTRADE implementation overview

COMTRADE is configured as part of the default waveform recording framework.
COMTRADE records will be for sag/swell events. The only configuration you need
to do is to enter your nominal voltage to enable waveform recording. COMTRADE
records are stored as read-only files on your meter’s internal FTP server, and are
deleted when you perform a Master reset of the meter.
By default:
• The meter is configured so COMTRADE records are generated for the default
waveform recorders.
NOTE: If you add additional waveform recorders and you want
COMTRADE files generated for these new recorders, you need to
configure a new COMTRADE module using ION Setup Advanced mode.
You can configure up to three COMTRADE modules.
• The oldest COMTRADE record is overwritten by the newest record when the
COMTRADE depth is exceeded.
NOTE: COMTRADE files can only be downloaded using an Ethernet
connection. They cannot be downloaded using serial, modem or Ethernet
gateway connections.

PowerLogic™ ION7400 series Verifying accuracy

Verifying accuracy
Overview of meter accuracy
All meters are tested and verified at the factory in accordance with International
Electrotechnical Commission (IEC) and American National Standards Institute
(ANSI) standards.
Your digital power meter typically does not require re-calibration. However, in some
installations a final accuracy verification of the meters is required, especially if the
meters will be used for revenue or billing applications.

Accuracy test requirements

The most common method for testing meter accuracy is to apply test voltages and
currents from a stable power source and compare the meter’s readings with
readings from a reference device or energy standard.

Signal and power source

The meter maintains its accuracy during voltage and current signal source
variations but its energy pulsing output needs a stable test signal to help produce
accurate test pulses. The meter’s energy pulsing mechanism needs approximately
10 seconds to stabilize after every source adjustment.
The meter must be connected to control power in order to conduct accuracy
verification testing. Refer to your meter’s installation documentation for power
supply specifications.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Verify the device’s power source meets the specifications for your device’s
power supply.
Failure to follow these instructions will result in death or serious injury.

Control equipment
Control equipment is required for counting and timing the pulse outputs from an
energy pulsing LED or digital output.
• Most standard test benches have an arm equipped with optical sensors to
detect LED pulses (the photodiode circuitry converts detected light into a
voltage signal).
• The reference device or energy standard typically has digital inputs that can
detect and count pulses coming from an external source (i.e., the meter’s
digital output).
NOTE: The optical sensors on the test bench can be disrupted by strong
sources of ambient light (such as camera flashes, florescent tubes, sunlight
reflections, floodlights, etc.). This can cause test errors. Use a hood, if
necessary, to block out ambient light.

Environment
The meter should be tested at the same temperature as the testing equipment.
The ideal temperature is about 23 ºC (73 ºF). Make sure the meter is warmed up
sufficiently before testing.
A warm-up time of 30 minutes is recommended before beginning energy accuracy
verification testing. At the factory, the meters are warmed up to their typical

184 7EN02-0374-01
Verifying accuracy PowerLogic™ ION7400 series

operating temperature before calibration to help ensure that the meters will reach
their optimal accuracy at operating temperature.
Most high precision electronic equipment requires a warm up time before it
reaches its specified performance levels. Energy meter standards allow the
manufacturers to specify meter accuracy derating due to ambient temperature
changes and self-heating.
Your meter complies with and meets the requirements of these energy metering
standards.
For a list of accuracy standards that your meter complies to, contact your local
Schneider Electric representative or download the meter brochure from
www.schneider-electric.com.

Reference device or energy standard

To help ensure the accuracy of the test, it is recommended that you use a
reference device or reference energy standard with a specified accuracy that is 6
to 10 times more accurate than the meter under test. Before you start testing, the
reference device or energy standard should be warmed up as recommended by its
manufacturer.
NOTE: Verify the accuracy and precision of all measurement equipment used
in accuracy testing (for example, voltmeters, ammeters, power factor meters).

Energy pulsing
Your meter has energy pulsing LEDs and a digital output that can be used for
energy pulsing.
Your meter has energy pulsing LEDs, one visible light and one infrared. These
LEDs emit pulses that are then used to determine the accuracy of the meter’s
energy measurements. The pulses of light indicate accumulated energy; the
meter’s accumulations are compared with the reference/standard’s accumulated
energy in order to help determine the meter’s accuracy.
Your meter also has a digital output that can be used for energy pulsing. The relay
closes (low impedance) and then opens (high impedance) to represent a pulse. If
the accuracy testing equipment has a voltage requirement, a current-limited
wetting supply voltage must be provided.
NOTE: Digital outputs on option modules should not be used meter accuracy
testing.

Verifying accuracy test meter settings

Your meter‘s power system and other parameters must be configured for accuracy
testing.

Meter parameter Value

Volts mode 4W-Wye (4 wire Wye)

PT/CT correction Disabled

Test mode Active
NOTE: In test mode, your meter’s billing
quantities stop accumulating, and the data
is sent to special test mode registers. These
registers are cleared when you exit test
mode.

Verifying accuracy test

The following tests are guidelines for accuracy testing your meter; your meter shop
may have specific testing methods.

1. Turn off all power supplying this device and the equipment in which it is
installed before working on the device or equipment.
2. Use a properly rated voltage sensing device to confirm that all power is off.
3. Connect the test voltage and current source to the reference device or energy
standard. Ensure all voltage inputs to the meter under test are connected in
parallel and all current inputs are connected in series.

4. Connect the control equipment used for counting the standard output pulses
using one of these methods:

Option Description

Energy pulsing LED Align the red light sensor on the standard test bench armature over the
energy pulsing LED.

Digital output Connect the meter’s digital output to the standard test bench pulse
counting connections.

NOTE: When selecting which method to use, be aware that energy

pulsing LEDs and digital outputs have different pulse rate limits.

186 7EN02-0374-01
Verifying accuracy PowerLogic™ ION7400 series

5. Before performing the verification test, let the test equipment power up the
meter and apply voltage for at least 30 seconds. This helps stabilize the
internal circuitry of the meter.
6. Configure the meter’s parameters for verifying accuracy testing.
7. Depending on the method selected for counting the energy pulses, configure
the meter’s energy pulsing LED or one of the digital outputs to perform energy
pulsing. Set the meter’s energy pulse constant so it is in sync with the
reference test equipment.
8. Perform accuracy verification on the test points. Run each test point for at
least 30 seconds to allow the test bench equipment to read an adequate
number of pulses. Allow 10 seconds of dwell time between test points.

Calculate the number of required pulses

The reference test equipment typically requires you to specify the number of
pulses required for a test duration of “t” seconds.
Normally, the number of pulses required is at least 25 pulses, and the test duration
is greater than 30 seconds.
Use the following formula to calculate the required number of pulses:

Ne Number of metering elements used

V Test point voltage in line-to-neutral volts (V) per phase

I Test point current in amps (A) per phase

t Test duration in seconds (s) which must be longer than 30 seconds

PF Power factor
Kt Pulse constant programmed in the meter under test in Wh/pulse

Round up the result of the calculation to the nearest integer number of pulses.

Calculation for number of required pulses

This example calculates the number of pulses required for an inductive load 3-
phase test point with a test duration of 60s; the source is configured to use V =
120V, I = 5A, PF = -0.5; the pulse constant of the meter under test is Kt = 1.8 Wh/
pulse.

Round the number up to the nearest integer: Number of pulses = 9

Percentage error calculation for accuracy verification testing

Accuracy verification testing requires you to calculate the percentage error
between the meter being tested and the reference/standard.
Calculate the percentage error for every test point using the following formula:
Energy error = (EM - ES) / ES x 100%
Where:

7EN02-0374-01 187
PowerLogic™ ION7400 series Verifying accuracy

• EM = energy measured by the meter under test

• ES = energy measured by the reference device or energy standard.
NOTE: If accuracy verification reveals inaccuracies in your meter, they may be
caused by typical sources of test errors. If there are no sources of test errors
present, please contact your local Schneider Electric representative.

Typical sources of test errors

If you see excessive errors during accuracy testing, examine your test setup and
test procedures to eliminate typical sources of measurement errors.
Typical sources of accuracy verification testing errors include:
• Loose connections of voltage or current circuits, often caused by worn-out
contacts or terminals. Inspect terminals of test equipment, cables, test
harness and the meter under test.
• Meter ambient temperature is significantly different than 23 °C (73 °F).
• Floating (ungrounded) neutral voltage terminal in any configuration with
unbalanced phase voltages.
• Inadequate meter control power, resulting in the meter resetting during the test
procedure.
• Ambient light interference or sensitivity issues with the optical sensor.
• Unstable power source causing energy pulsing fluctuations.
• Incorrect test setup: not all phases connected to the reference device or the
energy standard. All phases connected to the meter under test should also be
connected to the reference meter/standard.
• Moisture (condensing humidity), debris or pollution present in the meter under
test.

Accuracy verification test points

The meter should be tested at full and light loads and at lagging (inductive) power
factors to help ensure testing over the entire range of the meter.
The test amperage and voltage input rating are labeled on the meter. Refer to the
installation sheet or data sheet for your meter’s nominal current, voltage and
frequency specifications.

Watt-hour test point Sample accuracy verification test point

Full load 100% to 200% of the nominal current, 100% of the nominal voltage and
nominal frequency at unity power factor or one (1).

Light load 10% of the nominal current, 100% of the nominal voltage and nominal
frequency at unity power factor or one (1).

Inductive load (lagging 100% of the nominal current, 100% of the nominal voltage and nominal
power factor) frequency at 0.50 lagging power factor (current lagging voltage by 60°
phase angle).

VAR-hour test point Sample accuracy verification test point

Full load 100% to 200% of the nominal current, 100% of the nominal voltage and
nominal frequency at zero power factor (current lagging voltage by 90°
phase angle).

Light load 10% of the nominal current, 100% of the nominal voltage and nominal
frequency at zero power factor (current lagging voltage by 90° phase
angle).

Inductive load (lagging 100% of the nominal current, 100% of the nominal voltage and nominal
power factor) frequency at 0.87 lagging power factor (current lagging voltage by 30°
phase angle).

Revenue PowerLogic™ ION7400 series

Revenue
Revenue metering overview
Revenue metering is one of your device’s primary features.
The main purpose of a revenue meter is to provide measurements that are within
industry-accepted limits for accuracy over a defined range of operating conditions.
It also provides adequate protection against unauthorized alteration of these
measured quantities. International and national standards define industry accepted
accuracy limits. National and utility-based standards regulate protection against
unauthorized alteration of measured quantities.

Components of revenue metering

To meet government regulations and utility security requirements, the meter
incorporates three types of security systems.
The three types of security systems are:
• traditional anti-tamper mechanical seals on the meter
• a password-based security system for resetting meter values (for example,
Peak Demand reset)
• a hardware-based security system that prevents modification of revenue
quantities after the meter is locked
Refer to the installation guide shipped with your meter and accessories regarding
the installation of these security features.

Revenue firmware security features

Your revenue-specific meter has additional firmware security features.
• You can only upgrade to revenue-qualified firmware and frameworks.
• Your firmware upgrades are recorded in your meter’s event log. An additional
firmware upgrade log is stored on your meter. Contact technical support for
information on upgrade log retrieval
• You cannot perform resets or configure some revenue-specific parameters on
your meter while it is revenue-locked.

Protected features and settings

Your meter has features and settings that cannot be changed while the meter is
revenue-locked.
In order to prevent modifications to revenue-related settings and data on your
meter, some of the features and parameters on your meter cannot be edited once
the meter is revenue-locked. For a complete listing of revenue-locked features and
settings, download the ION Device Template Reference, available from
www.schneider-electric.com

Revenue meter pre-installation procedure

You must configure and revenue lock your meter before installation.
• Clear all meter data prior to installing your revenue meter.
• Unlock your revenue meter.
• Configure the required revenue settings specific for installation. Once the
meter is locked, these settings cannot be changed.

7EN02-0374-01 189
PowerLogic™ ION7400 series Revenue

NOTE: If you are using ION Setup to configure your meter, allow for any
communication delays before removing power to your meter.
• Verify the revenue settings have been implemented.
• Revenue lock your meter.
• Verify the meter is revenue-locked.
• Install the meter according to your meter’s install sheet.
• Install the voltage and current terminal covers according to the sealing kit
installation instructions.

Revenue locking
Revenue locking your meter helps prevent modifications to revenue-related
settings and data on your meter, or tampering with your meter’s voltage and
current connections.
Revenue locking may be required to help meet government regulations and utility
security requirements, or can be used to help ensure the validity of revenue data.

PT/CT correction
PT/CT correction, also called instrument transformer correction, can help reduce
the need to replace transformers in installations where high accuracy is required.
The primary application for PT/CT (potential transformer / current transformer)
correction is to apply correction factors for ratio errors and phase angle errors to
instrument transformers. PT/CT correction is done for each current and voltage
input to the meter and only affects 1-second power meter data and values derived
from it, such as energy or demand. No high-speed, harmonics or waveform values
are affected by the correction.
NOTE: For those familiar with ION architecture, the relevant 1-second Power
Meter module outputs are compensated using the Instr Xformer (ITC)
Correction module, and therefore so are all other modules that use that Power
Meter module’s data.
See the ION Setup online help, available from www.schneider-electric.com, for
instructions on how to configure PT/CT correction on your device.
See the ION Reference, available from www.schneider-electric.com, for detailed
information about the Instr Xformer Correction (ITC) module and how it applies PT/
CT correction to your device.

Transformer line loss compensation

Transformer Loss Compensation (TLC) is the method for compensating for the
measurable losses that occur when there is a physical separation between the
meter and the actual billing point.
Transformer Loss Compensation (TLC) is used when a meter’s actual location is
different from the electrical location where change of ownership occurs; for
example, where meters are connected on the low-voltage side of power
transformers when the ownership change occurs on the high-side of the
transformer. Meters are usually installed on the low-voltage side of a transformer
because it is more cost-effective. There are also cases where change of ownership

7EN02-0374-01 191
PowerLogic™ ION7400 series Revenue

can occur halfway along a transmission line where it is impractical to install a

meter. In this case, power metering must again be compensated.
NOTE: Due to the variation in installations, advanced knowledge of power
systems and connection methods is required before transformer loss
compensation can be properly implemented. Data parameters should only be
programmed by qualified personnel that have appropriate training and
experience with Transformer Loss Compensation calculations.
See the Transformer Line Loss Calculations technical note available from
www.schneider-electric.com.

Time of use
Time of use (TOU) is often used when a utility has set up schedules with different
rates based on time of day, type of day and date when energy is consumed.
You can view the TOU active rates and seasons through your meter’s display.
See the ION Setup online help, available from www.schneider-electric.com, for
instructions on how to configure time of use on your meter.
See the ION Reference, available from www.schneider-electric.com, for a
description of the Time of use module and its settings.
