The ION Meter in an Enterprise Energy Management System

You can use ION7550 and ION7650 meters as standalone devices, but their extensive
capabilities are fully realized when used with ION software as part of an enterprise
energy management (EEM) system.

EEM systems give energy suppliers, service providers, and large industrial and
commercial energy consumers the tools to meet all the challenges and opportunities of
the new energy environment. EEM systems use real-time information and control to
directly address a broad range of requirements throughout the power delivery chain and
across an entire enterprise. These systems offer an integrated solution to managing
new billing structures, distributed generation, energy purchasing, energy cost control,
operational efficiency, and power quality and reliability.

Applications that include the meter typically require additional equipment. Display and
analysis software tools are almost always used to manage, interpret and distribute the
data measured or logged by a meter. There are usually a variety of tools used, and
often these tools are connected using different communications standards and
protocols. In many cases, a meter must also provide non-critical control capabilities and
device-level data sharing.

The meter can adapt to many situations. Advanced communications allow data to be
shared simultaneously across multiple networks, built-in I/O provides monitoring and
control capabilities, and a variety of display and analysis tools monitor your power
system.

Processor, the Log Inserter, and the Query Server. Designer uses a WYSIWYG
graphical user interface to pictorially represent a node’s configuration (i.e., how the
different ION modules are linked together in a framework). In addition to giving you the
ability to change the settings of any ION module, Designer also lets you change existing
links between modules, add new links, add new modules or delete modules. Designer
helps you visualize the logic when you are programming custom functionality in an ION
device.

For more information, refer to the Designer section in the online
Power Monitoring Expert Help.

ION Architecture Overview ION7550 / ION7650 User Guide

ION Architecture Overview

ION architecture is an object-oriented architecture with a modular structure that is the
foundation of every component in an ION system. Although the meter ships with a fully
functional, factory-configured template, its modular design enables you to customize
the functions of the meter. The graphic below outlines the key components of the
architecture in your meter: the node (meter), the template, frameworks, ION modules
and module managers. For more detailed information on ION Architecture and
individual modules, refer to the ION Reference.

Nodes: ION architecture begins
with the node. In this example,
the node is an ION meter.

Templates: A template is
the meter’s program. It is a
file, comprised of several
framework configurations,
that defines the meter’s
capabilities and how it
operates. A factory­configured template with a
broad range of functionality
is created for each firmware
revision of the meter.

Frameworks: A
framework is a group of
ION modules linked
together and configured to
perform a specific function,
such as power quality
monitoring. For example, a
meter with a power quality
framework can monitor
disturbances, monitor real­time harmonics and
analyze surges.

ION Module Detail

All ION modules have a similar structure.
Each module is identified by a unique
label that generally implies its function.

Modules receive data from
inputs. Link modules together
by assigning the output of one
module to the input of another.

Managers: ION managers act
as directories of modules,
organizing the available
modules in a meter. There is
one manager for each type of
module (Power Meter manager,
Maximum manager, etc.).

ION Modules: ION modules are the
building blocks of ION architecture.
Each type of module is designed to
perform a specific task, similar to a
single function in a conventional
power meter. The functions
available in the meter result from
linking different types of modules.
By linking modules together, you
can create custom functions for your
power-monitoring system.

ION7550 / ION7650 User Guide Upgrading Your Meter

Upgrading Your Meter

You can upgrade the firmware (operating software) on your meter using ION Setup.

General Upgrading Considerations

Upgrading to compatible firmware versions

Ensure that the firmware version that 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).

For example, if your meter is an ION7550, you must use ION7550 firmware, not
ION7650 firmware. The model is indicated in the firmware filename.

You can download meter firmware from the website.

Recording your device’s usernames and passwords

Ensure that you record your device’s usernames and passwords prior to upgrading the
device firmware.
Lost passwords cannot be recovered. If your device’s user access information is lost,

you must return the device for factory reconfiguration, which resets your device to its
factory defaults and destroys all logged data.

NOTICE

DATA LOSS

Record and store your device’s user and password information in a secure
location.

Failure to follow these instructions can result in data loss.

See “Security” on page 63 for more information on the device’s security settings.

Using a laptop computer to upgrade

Laptop computers generally have different default power properties than desktop
computers. Incorrect power options can adversely affect device upgrading because the
connection between the laptop and the device must be maintained in order to complete
the upgrade successfully. 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 a meter 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 hard disks so that they do not shut down after a certain period of time
(i.e. set to “never”).

• Turn off power suspension (e.g. system stand-by) and hibernate options.

• Disable options that power down the laptop when it is closed. This prevents a shut
down if the laptop is accidentally closed.

• Disable the screen saver; screen savers can burden the CPU.

7EN02-0248-08 27

ION7550 / ION7650 User Guide Front panel LEDs

Front panel LEDs

The front panel LEDs are as follows:

• The green operation LED (top) should always be on when the meter is in service.

Contact Technical Support if this is not the case.

• The red watthour LED (middle) is factory configured to be a Wh (del+rec) pulser.

During the course of normal operation, this LED should blink intermittently as the
meter measures power system energy.

• The red alarm LED (bottom) on the front panel of the meter is user programmable.

Possible applications include sag/swell alarming, setpoint annunciation, and tariff
notification. Like all the other outputs on the meter, this port can be controlled by a
Digital Output, Pulser, or Calibration Pulser module.

Backlight operation and display contrast

The front panel display is factory set to dim five minutes after the last button press but
can also be user-configured. If the front panel is dimmed, press any button to return the
display to full brightness. The front panel display is adjusted at the factory to the optimal
contrast level. Use the Display Setup menu to adjust the contrast, if necessary (see
“Display Setup Menu” on page 41).

Status bar

Display Screen Types

The Status Bar of the meter is located along the top of all display screens. When in data
display mode, the Status Bar shows the date in MM/DD/YYYY format (configurable),
the current local time in 24 hour format, and the data display screen title.

The meter’s front panel displays measurements, configurable settings, and current
configuration data in various forms. These data display screens are described below.

Numeric displays

Numeric displays show multiple parameters at a time: two, three, three with a
timestamp, four, eight, ten, or twenty. When displaying numeric values for current and
power quantities, the front panel shows resolution to three decimal places by default.
All other values are displayed to two decimals of accuracy. For finer resolutions, use
Vista software to display the data.

NOTE: If the front panel is unable to read a numeric value, or if the value is not
available, it displays a dash (—).

Automatic units

The front panel automatically scales the units for basic measurements, such as voltage,
current and power parameters. For example, a measurement of 2,000 Watts is
displayed as 2.000 kW. A measurement of 2,000,000 Watts is displayed as 2.000 MW.
The meter makes these conversions using your PT and CT ratios.

NOTE: The meter only performs these automatic units if the measurement is derived
solely from the Power Meter module’s output.

7EN02-0248-08 33

Display Screen Types ION7550 / ION7650 User Guide

Phasor diagram displays

Phase information is displayed in phasor diagram format. Phasor diagrams are
accompanied by tables that state the angle and magnitude of each phasor. In cases
where phasors are too small to be represented graphically, they are only shown as
table entries.

Event log displays

Event Log displays alert you to recent events written to the meter’s event log. Use the
vertical (Up/Down) navigation buttons to move through the list.

For details on altering the meter’s Event Log characteristics, such as log depth and

the histogram (K Factor and Crest Factor only appear in current harmonic histograms).

On ION7650 meters, use the vertical navigation buttons on the meter front panel to
select individual harmonics (from 2nd to 63rd) in the histogram and view data specific to
each of them (V1, V2, V3, I1, I2, and I3 only).

An arrow appears below the harmonic selected. Harmonic magnitude is displayed
as an absolute value and as a percentage of the fundamental. The phase angle of each
harmonic is also provided. To return to the THD values, position the arrow below the
fundamental.

Trend bar graph displays

Bar graph displays can show up to four real-time (numeric) parameters along with their
upper and lower extremes.

Each bar graph automatically scales its output based on the magnitude of its extremes.
The real-time value of each bar graph is displayed to the right of the graph.

NOTE: Scaling is applied separately to each bar graph in the display. Do not compare
the magnitudes of two values based on the size of their bars.

Trend displays

The Trend Display screen graphs the historical data of up to four different parameters

Display Module Settings

A Display module controls which values are displayed on a display screen, and how
these values are presented. Each Display module corresponds to one meter display
screen.

The Display module’s Source inputs are linked to the numeric parameters you want to
display. These parameters are sent to the front panel when the Display module’s Show
input is pulsed.

The Display module’s setup registers determine screen type (e.g. numeric, event log,
trend bar etc.), softkey name and number, and screen title of each display. Many
Display modules available in the meter are used in the factory configuration. You can
alter some characteristics of the factory-configured displays by modifying the setup
register of the Display modules.

The Display module’s setup registers determine how the Source data is presented on
the front panel display. Depending on the display screen type, which is specified by the
Screen Type setup register, you can use up to twenty Source links to a single Display
module. This means you can show the values of up to twenty different sources on one
front panel display screen. In addition, you can display harmonics, trending, and event
logs (see the Screen Types table below).

module only displays the Display Type number, and breaks any links to parameters that
it cannot display.

For example, if you have a display screen with four parameters, and you select a
Screen Type of ONE PARAMETER, the first parameter is displayed and the other three
links to the ION Display module are severed.

Changing the parameters that are displayed

The meter’s default display configuration shows a comprehensive set of parameters.
Changing these parameters requires that you alter the links between various ION
modules. Complete details on changing the front panel displays are provided in the

Configuring Front Panel Displays

ION7550/ION7650 meters ship with preconfigured display screens. Most users find that
the preconfigured data screens displayed by the front panel LCD (Liquid Crystal
Display) suit their needs. However, front panel displays can also be customized if
required.

The meter’s display screens can be customized to show virtually any measurement or
calculation of which the meter is capable. For example, you could do one or all of the
following:

Trigger

Maximum Module

Reset

Source

This ION module holds the value that you
can reset from the front panel. You may
also have to create and configure it.

• change displayed parameters, such as from Vll to Vln or Vllab to Vlna

• aggregate displays from multiple meters, such as using a meter’s front panel display

to view data collected by one or more TRAN units (see “Displaying Data from Other
Meters” on page 52)

• adjust character size to be different on each screen

• change data display settings such as backlight timeout, automatic display scrolling,

parameter update rate and display mode

In order to customize your front panel display screens, you must make changes to ION
modules that belong to the display framework.

Trigger output register: this is your first display screen on the meter. Accordingly, the
second Display module’s Show input is linked to the Scroll module’s second Trigger
output in order to setup the second display screen, and so on.

The order in which data displays depends on the numbering of the Display modules.
Therefore, the data linked to Display module 1 is displayed on the first front panel
screen and so on. Scrolling between the display screens is done with the Up and Down
arrow buttons on the front of the meter.

You cannot configure displays from the front panel.

Changing default display frameworks

The factory-configured Display framework uses many of the Display modules available
in the meter. Only a few of the default screens have room for extra data. To make a
significant modification to the existing display framework, you either have to create new
display modules and configure them, or change the links and settings of the modules
in the existing Display framework (or both).

Four common modifications are discussed in the following sections:

• removing a display screen

• adding a new display screen

• replacing the parameters in an existing display screen

• creating custom trend bar graphs

Removing a display screen

Use caution when deleting modules, as any dependant modules are also affected.
Designer informs you of dependant modules if they exist on the same node.

3. Press Delete. This also deletes all links to that particular Display module.

4. Select Send & Save to save your changes to the meter.

If the display screen you are deleting is part of the automatic scrolling cycle, you should
reconfigure the links from the Scroll module’s Trigger outputs to the remaining Display
modules so that the following considerations hold true:

• The first Display module in the scrolling cycle is linked to the Trigger 1 output of the

Scroll module.

• The last Display module in the scrolling cycle (module n) is linked to the

Trigger n output of the Scroll module. For example, if your scrolling cycle consists of
5 screens, then Trigger 5 should be linked to the fifth module in the cycle.

• The Wraparound setup register of the Scroll module designates the last trigger

output (Trigger n). Expanding on the previous example, since Trigger 5 is the last
trigger, the Scroll module’s Wraparound setup register would have a value of 5.

Adding a new display screen

You can create a new front panel display without dismantling any of the existing
displays.

Adding a new display screen in Designer

1. Open your meter in Designer and navigate to Advanced Setup > Frameworks >
Display Framework.

2. Drag out a new Display module and right-click on the center of the module icon to
access its setup registers.

3. Define the module’s characteristics (display format) by adjusting its setup registers.

4. Link any required data to the Source inputs of the Display module.

5. Select Send & Save to save your changes to the meter.

If you want your new screen to appear in the automatic scrolling cycle, then you must
link the Show input of the Display module to a Trigger output of a Scroll module. See
“Removing a display screen” on page 47 for considerations on re-linking Scroll module
Trigger outputs.

Changing displayed parameters in an existing screen

Use Designer software to change displayed parameters in existing screens on your
meter.

To change parameters, link the output register containing the numeric data you want to
display to the Source inputs of the Display module. If there is not a free Source input,
you will have to first delete (i.e., unlink) an existing link to a Source input.

Source 4 Real-Time value for Bar Graph #2 Bar graph #2 will not appear if this input is not linked

Source 5 Minimum for Bar Graph #2 Link to the output of a Minimum module

Source 6 Maximum for Bar Graph #2 Link to the output of a Maximum module

Source 7 Real-Time value for Bar Graph #3 Bar graph #3 will not appear if this input is not linked

Source 8 Minimum for Bar Graph #3 Link to the output of a Minimum module

Source 9 Maximum for Bar Graph #3 Link to the output of a Maximum module

Source 11 Minimum for Bar Graph #4 Link to the output of a Minimum module

Source 12 Maximum for Bar Graph #4 Link to the output of a Maximum module

Typically, the minimum and maximum values for each bar graph come from links to the
outputs of Minimum and Maximum ION modules that are themselves linked to the real­time parameter shown in the bar graph.

NOTE: This feature works only if the meter’s Volts Mode is NOT set to Demo. When
the meter is in Demo mode, a default trending log showing Vll ab, Ia, PF and KW is
displayed rather than the actual log that has been linked to the Display module.

The diagram below shows an example of the links necessary for one bar graph (in the
top position).

A bar graph reports a “Mn/Mx

modified so that a minimum value is larger than a maximum value. It also
displays when a Display module configured for Trending has not been
linked to a Data Recorder module, so there are no values to plot.

This displays whenever an invalid log value is recorded. In addition,
trend graphs cannot be viewed.

Adding New Trend Display Modules

Users who are familiar with the ION architecture, Designer software, and Vista software
can link additional Display modules for trending. Here are some guidelines:

• You can configure any Display module as Trend Display by setting the Screen Type
setup register to Data Log Trend - Log Source 1 to 4.

• The maximum number of Trend Display modules permitted is 10.

• Any Data Recorder module output log can be connected to a Trend Display module.

– The Data Recorder module output log must be connected to the first input of the

associated Trend Display module.

– Even though a Data Recorder module has up to sixteen Source inputs, only the

first four Source inputs can be viewed in Trend Display.

• With External Numeric modules, min/max can be set in Vista.

– The External Numeric module that sets up the minimum value for the displayed

data must be connected to the second input of the associated Trend Display
module.

– The External Numeric module that sets up the maximum value for the displayed

data must be connected to the third input of the associated Trend Display
module.

Displaying Data from Other Meters

Data can be read at a workstation using Power Monitoring Expert software, but there
may be situations which require the data to be read at the source. With just one
ION7550/ION7650 meter, you can view the data collected by numerous TRANs and
other devices over a serial network. This is done using the Modicon Modbus™ protocol.
The ION7550/ION7650 meter with the front panel display acts as the Modbus Master,
while the other meters are the Modbus Slaves. The display meter has its protocol set
to MODBUS MASTER, and each TRAN meter is configured to use the MODBUS protocol.

NOTE: A TRAN (transducer) meter is a basic meter model without a front panel display;
a TRAN can be used with a remote display.

See the Modbus and ION Technology technical note for more information on how to
configure your meter as a Modbus Master.

The ION7550 meter with front panel display is the Modbus Master, showing data from
the other meters (the Modbus Slaves) on the serial connection.

If this were the complete display framework, then there would be a total of four screens
showing data on the ION7550 with front panel display: one screen from each TRAN (the
ION7550 and the ION7300) and two screens from the ION6200. Notice how the
ION6200 has had its data displayed on different screens.

Configuring your custom display framework

To aggregate data from multiple devices on a network and display it on an
ION7550/ION7650 meter, follow the steps below. The framework changes are made to
the meter displaying the data.

1. Connect to your meter in Designer, ensuring that Options > Show Toolbox is
checked.

If you want a blank work space, where you can keep your master configuration,
simply drag out a new grouping object from the toolbox, name it appropriately and
double-click on your new grouping object.

2. Drag out a Modbus Import module and right-click on the Modbus Import module to
access the setup registers.

3. Use the ReadNow input of the Modbus Import module if you want to setup a trigger
source that activates a read (i.e. a pulse). If you do not link ReadNow the module
polls Modbus devices continuously.

7EN02-0248-08 53

Displaying Data from Other Meters ION7550 / ION7650 User Guide

4. Right-click the Modbus Import module to configure setup register settings.

Configure the following setup registers as needed: Slave Address, Register Address,
Number of Registers, Format and Scaling. The supported Slave Address range (Unit
ID on ION meters) for a Modbus device is from 1 to 247.

5. Repeat steps 2 - 4 for every meter or TRAN in the serial network whose data you
want to display on the meter with the front panel.

The meter with the front panel requires a separate Modbus Import module for each
meter whose data it displays, because all meters in the network have unique Unit IDs.
This is how the Modbus Master distinguishes which meter (Slave Address) is
providing what data (Register Address).

6. Link each Modbus Import module’s output registers to the appropriate Display
module’s Source inputs.

7. Define each Display module’s characteristics (display format) by adjusting its setup
registers. Do the same to the Display Options module if so desired.

8. See “Removing a display screen” on page 47 for considerations on re-linking Scroll
module Trigger outputs.

This step is important if you want to have your new screens appear in an automatic
scrolling cycle, or if your custom framework has fewer display screens than the
factory configuration, and you need to adjust the Scroll module’s settings.

9. Select Send & Save to save your changes.

Basic Power Meter Setup ION7550 / ION7650 User Guide

Basic Power Meter Setup

Basic configuration of the meter is provided by the Power Meter module. The Power
Meter module is the main connection between the power system measurements and
all other ION modules in the device. This module reports the values for all voltage,
current and power measurements. The Power Meter module’s setup registers describe
details of the power system being monitored.

Basic setup is typically performed when the meter is initially put into service, although
the device cannot operate properly until the Volts Mode and PT and CT ratios are set.
Some registers may need to be changed to refine the device’s operation. Refer to the
ION Reference for more details on the Power Meter module.

Configuring Basic Setup

Use the front panel or software to perform basic meter setup.

Security overview ION7550 / ION7650 User Guide

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 meter

Your meter comes with security features that you can configure to help protect against
unauthorized configuration or access to your meter’s data through the meter’s display
or communication ports.

Front panel security

You must enter the meter password before you can make configuration changes to your
meter. Front panel password protection can be disabled, but this is not recommended.
See “Configuring Standard security using the front panel” on page 70.

Standard meter security

Standard security is enabled by default from the factory. Any time you make
configuration changes to your meter, you must enter a password. See “Configuring
Standard security using ION Setup” on page 72

Advanced meter security

Advanced security settings allow you to:

• Add up to 50 users, each with unique access privileges.

• Configure communications lockouts to limit the number of invalid login attempts

permitted for each protocol, and set the priority of associated device events.

• Enable or disable Modbus programming.

• Enable or disable programming through the front panel.

See “Configuring Advanced Security using ION Setup” on page 73

Port number reassignment on Ethernet protocols

You can change the default port number assigned to Ethernet protocols. This feature
can assist in preventing port service overlap. Network ports that remain open should be
changed from their default values whenever possible. See “Network protocol control”
on page 93.

64 7EN02-0248-08

ION7550 / ION7650 User Guide Time synchronization security considerations

Once your meter is configured, all ports related to unused network protocols should be
closed (disabled). When required, you can always temporarily open a port for specific
activities such as periodic firmware or software downloads.

Enable/disable communication ports

You can disable your meter’s communication ports when they are not in use. This
includes serial and Ethernet communication ports. See “Disabling serial
communications ports” on page 88 and “Network protocol control” on page 93.

Leaving unused ports open provides additional attack vectors for a potential attacker.
Minimizing the number of entry points into a meter reduces the likelihood of
unauthorized intrusions.

Event logging

Your meter records meter functions, events and changes to meter parameters and logs
them as entries in the event log. Security-related events such as resets, successful or
unsuccessful login attempts, user lockout, and meter configuration changes are also
recorded in the event log along with a timestamp and the user 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. See “Event
Logging” on page 156.

Syslog

They Syslog 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 overwrite the 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. See
“Syslog” on page 96

Revenue meter security

Your meter can be protected by hardware-lock security and anti-tamper sealing. See
“Additional revenue metering security” on page 77.

Software security

Power Monitoring Expert or ION Setup add another layer of access-level security to the
meter. With Power Monitoring Expert or ION Setup, you can configure multiple users
with different passwords and specify access rights. Power Monitoring Expert or ION
Setup security only applies to users who are accessing the meter using the software.

For more information on Power Monitoring Expert or ION Setup security, refer to the
software’s online help.

Time synchronization security considerations

Depending on the software security settings, a workstation that connects to the meter
may send a time synchronization signal to synchronize the meter's internal clock with
the workstation's clock. This can cause overlaps in the demand intervals, and
timestamps in the data logs may not be accurate.

The Time Sync Source setup register, located in the Clock module, identifies the
communications port that will accept time synchronization broadcasts. Time

7EN02-0248-08 65

Security recommendations and best practices ION7550 / ION7650 User Guide

synchronization signals on other communications ports are ignored. You can configure
this setup register through ION Setup or the Designer component of Power Monitoring
Expert.

Refer to the Time synchronization & timekeeping technical note for more information on
implementing time synchronization.

Security recommendations and best practices

Use recommended security configuration and best practices to help improve security
on your meter.

Recommended security configuration

• Enable front panel security on your meter.

• Enable advanced security on your meter.

– Configure users and passwords to help minimize access to your meter.

– Disable web server programming to help prevent configuration access to your

meter over the web.

– Disable Modbus programming to help prevent access to your meter using

Modbus. This disables write access to all Modbus registers, and only allows
read access to the registers in the Modbus Slave modules.

– Configure the protocol lockouts to help minimize access to your meter.

– Ensure that the Factory user is disabled.

• Change Ethernet port numbers from their default values wherever possible.

• Disable all unused serial and network communications ports.

Password best practices

The following recommendations help improve security on your meter:

• Change your meter’s front panel password from the default factory value of 0 (zero).

• Make your meter’s front panel and user-specific passwords as complex as possible.

For passwords created in ION Setup, there is a password strength indicator.
Password strength ranges from Very weak to Very strong.

NOTE: Make sure that the user password you enter is compatible with the software
used to communicate with your meter. For example, some energy management
software applications only accept letters, numbers and underscores, and do not accept
special characters.

• Schedule regular changes to your meter’s front panel and user passwords.

• Record and store your device’s user and password information in a secure location.

Lost passwords cannot be recovered. If your device’s user access information is lost,
you must return the device for factory reconfiguration, which resets your device to its
factory defaults and destroys all logged data.

NOTICE

DATA LOSS

Record and store your device’s user and password information in a secure
location.

Failure to follow these instructions can result in data loss.

66 7EN02-0248-08

ION7550 / ION7650 User Guide Additional security recommendations

Additional security recommendations

• For the highest level of security, use a hardware-locked, sealed meter with
advanced security enabled and configured for minimum access.

• Protect all Ethernet devices with a properly configured firewall that prevents Telnet
access over port 23.

• Save a copy of your meter’s security configuration (.scf) file in a secure location in
addition to the password and user information.

• Set meter communication ports to the Factory protocol only when necessary to
permit access by Schneider Electric Technical Support, and return the ports to their
original settings as soon as possible.

• Set the meter’s time synchronization source to a secure communications port (this
disables time synchronization on all other ports). See the Time synchronization &
timekeeping technical note for more information.

Default security settings

The meter ships from the factory with standard security enabled and a default password
of 0 (zero). Default security settings for meters shipping from the factory are defined in
the following table. If you upgrade your meter to use the latest firmware, your meter’s
existing security values are not affected; the values will retain their current settings.

Standard meter security

Security setting Value

Allow Web Server programming Disabled (not allowed)

1

Allow Modbus programming

Protocol lockout attempts 8 (for all protocols)

Session timeout 30 minutes

Lockout duration 1440 minutes (24 hours)

Valid login event priority 0

Invalid login event priority 128

Lockout event priority 255

Protocols selected for security All protocols (ION, HTTP, FTP, Telnet, Factory, Front panel)

Factory user Disabled

Factory Access Minutes 0

1

This setting only applies to advanced security.

Disabled (not allowed)

Unless otherwise noted, these security settings apply regardless of whether the meter
has standard or advanced security enabled; for example, if you change the lockout
duration to 720 minutes (12 hours), that is the lockout duration for the meter in standard
security or in advanced security.

Standard meter security lets you configure the meter through the front panel or with
communications software using a meter password.

Standard meter security is enabled by default on all ION7550/ION7650 meters; all
configuration functions using the front panel and software are password-protected.

If you make configuration changes to the meter via the front panel, the meter prompts
you for its password before accepting any configuration changes. Similarly, if you make
any configuration changes through ION software or an internet browser, you are
prompted by the meter for its password (and sometimes the user name, USER0). After

7EN02-0248-08 67

Advanced meter security ION7550 / ION7650 User Guide

you enter the correct meter password and confirm the new configuration, the changes
are saved to the meter.

Note that the front panel prompts you for the meter password before you make your first
configuration change. You do not need to re-enter the password for each subsequent
change. However, if you perform no additional configuration changes for five minutes,
you will need to re-enter the Setup menu and provide the valid meter password to
resume making changes. This is because the meter returns from setup mode to data
display mode after five minutes of inactivity.

Advanced meter security

Advanced meter security allows you to configure up to 50 users, each with unique
access rights to the meter. Access rights consist of the following levels where you can:

• Time sync: set the time on the meter.

• Read: view any parameter except the security configuration.

• Peak demand reset: perform a reset of peak demand values (for example, sliding
window demand for kW, kVAR, kVA etc.).

• Full meter configuration: configure any programmable register on the meter
except for registers related to the security setup, registers that result in a demand
reset, or actions that place the meter in test mode.

• Test mode: put the meter into test mode.

• Advanced security configuration: configure Advanced security for the meter, full
meter configuration must also be set to YES.

Use the Setup Assistant in ION Setup to configure Advanced security. When
configuring users, in most cases you must set Read Access to YES. However, you can
set up a user without read access; for example, you can create a user who can only
timesync the meter. In some cases, such as Advanced security configuration access
(Security Config Access setup register), you must set multiple access options to YES.
When you are configuring Advanced security, ION Setup prompts you about improper
or incomplete user configurations.

Entering an advanced security user and password in ION software

When you use ION software to view data or make a change to a meter that has
advanced security enabled, you are prompted to enter a valid user name and password
combination.

User names in advanced security are fixed as USER1 through USER50.

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 meter password

– Disable broadcasting time synchronization (advanced security only)

68 7EN02-0248-08

ION7550 / ION7650 User Guide Communications protocol lockout overview

– 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 password

Communications protocol lockout overview

The communications protocol lockout advanced 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). By default, all protocols are set to eight invalid attempts
(Ftp Lock Attempts, Factory Lock Attempts, Frontpanel Lock Attempts, ION Lock
Attempts, Http Lock Attempts setup registers). Setting the value to 0 (zero) disables the
lockout feature for that protocol.

Protocols that are not session-based, such as ION or HTTP, send security credentials
with each packet transaction. For these protocols, you can configure how often the
meter registers invalid login attempts by setting the session timeout (ION Silence
Minutes and Http Silence Minutes setup registers), during which time only the first
invalid login attempt is counted towards the invalid login count. Each invalid attempt
using a different User/Password combination is counted. Session timeout is specific to
the protocol and communications port used, for example, ION over the COM1 serial
communications port.

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.

The lockout duration (Lockout Duration Minutes setup register) applies to all configured
protocol lockouts and defines the length of time (in minutes) that a User/Password
combination remains locked out. The default lockout duration is 24 hours (1440
minutes). The meter blocks login attempts from that User on that protocol and
communication port until the lockout duration has passed.

NOTE: Lockout is protocol-specific. For example, if the user is locked out using ION
over Ethernet, the same user can still access the meter by entering the correct User/
Password combination over a different protocol and communications port.

For advanced security login events, you can set the event priority for valid login
attempts (Valid Auth Priority), invalid login attempts (Invalid Auth Priority) and protocol

7EN02-0248-08 69

Configuring meter security ION7550 / ION7650 User Guide

lockout events (Locked Auth Priority). These settings apply to all configured lockouts.
Setting the value to 0 (zero) disables logging for those events.

Factory access and standard security

If a user tries to login to factory-level access (using Telnet or Hyperterminal) on a meter
with standard security, both of the following conditions must be met before the meter
can proceed with subsequent checks:

• Factory Access Minutes setup register is not 0 (zero).

• The user and password information for factory-level access has been entered

correctly.

If both conditions are met, the meter checks the following to determine if access will be
granted:

• Front panel button: if the time since one of the meter’s front panel buttons was

pushed is less than the Factory Access Minutes register value, the user is given
access.

• Power cycle: if the time since the meter was powered up is less than the Factory

Access Minutes register value, the user is given access.

• Factory Access Minutes edit: if the time since the Factory Access Minutes register

value was edited is less than the Factory Access Minutes value, the user is given
access.

If any one of these conditions are met, the user is given access. If none of these
conditions are met, the user is not given factory-level access on a meter with standard
security even if they entered appropriate user and password information.

Factory access and advanced security

If a user tries to login to factory-level access (using Telnet or Hyperterminal) on a meter
with advanced security, all three of the following conditions must be met before the
meter can proceed with subsequent checks:

• Factory Access Minutes setup register is not 0 (zero).

• The user and password information for factory-level access has been entered

correctly.

• The Factory user has been enabled.

NOTE: The Factory user can be enabled and disabled on the user configuration screen
of the ION Setup advanced security wizard.

Additional revenue metering security ION7550 / ION7650 User Guide

For more information on ION7550/ION7650 revenue meters see the ION7550/ION7650
Revenue Meter product option document.

Revenue lock security option

ION7550/ION7650 meters offer a revenue-locked security feature. To make
configuration changes on a revenue-locked meter, you must first unlock the meter.

Revenue lock and protected values

The revenue-related settings on meters with this option are factory configured and
cannot be changed, even in test mode.

Typical values that are protected include:

• kWh, kVARh, kVAh delivered, received, del-rec, del+rec.

• kW, kVAR, kVA Sliding Window demand min and max values.

• Digital Outputs controlling the energy pulsing applications.

• All Power system settings, including PT and CT ratios.

In certain countries revenue certification is void if the hardware lock is broken.

The revenue lock option combined with Standard or Advanced security offers the
highest level of security.

Locked module listings

For a complete list of locked modules specific to your meter and firmware, refer to the
ION Device Template Reference or contact technical support.

(fiber) connections. You can communicate with your meter using SNMP
or FTP (for IEC 61850 and COMTRADE) via Ethernet.

Communications Connections

The following section provides reference for connecting to the meter’s various
communication ports. For the most current communication specifications, see your
meter’s Installation Guide.

Most communications connections to the meter are made to the Communication Card
(Comm Card), found on the rear of the meter. Optical connections are made to the port
on the front of the meter. See the diagram below for details.

General bus wiring considerations

Devices connected on the bus, including the meter, converter(s) and other
instrumentation, must be wired as follows:

• Connect the shield of each segment of the cable to ground at one end only.

• Isolate cables as much as possible from sources of electrical noise.

• Use an intermediate terminal strip to connect each device to the bus. This allows for
easy removal of a device for servicing if necessary.

Avoid 3-way “Star”
connection point

• Install a ¼ Watt termination resistor (RT) between the (+) and (-) terminals of the
device at each end point of a straight-line bus. The resistor should match the
nominal impedance of the RS-485 cable, which is typically 120 ohms (consult the
cable manufacturer’s documentation for the cable’s impedance value).

RS-485 connection methods to avoid

Any device connection that causes a branch in the main RS-485 bus should be avoided.
This includes star and tee (T) methods. These wiring methods cause signal reflections
that may result in interference. No more than two cables should be connected at any
connection point on the RS-485 bus. This includes connection points on instruments,
converters, and terminal strips. Following these guidelines ensures that both star and tee
connections are avoided.

Avoid 3-way “T”
connection point

Optical Port Connections (COM4) ION7550 / ION7650 User Guide

Optical Port Connections (COM4)

The front optical port is designed to accept ANSI Type 2 magnetic couplers. It can be
used to communicate real-time measurements to a portable computer or for meter
configuration via the ION, Factory, Modbus RTU, or DNP 3.00 protocols.

Magnetic coupler
attached to front
optical port

To enable communications from the optical port, configure the Comm 4
Communications module. The Protocol, the Baud Rate and Unit ID setup registers must
properly match your system. When creating the site in ION software, ensure that RtsCts
and DTR settings are both disabled (set to No/Off) in the COM4 serial site.

Refer to the Magnetic Optical Couplers technical note for more information.

Ethernet Connections (optional)

This section only applies if your ION7550/ION7650 meter has an Ethernet option.

Ethernet

There are two Ethernet port ordering options available: a 10BASE-T/100BASE-TX port
with an RJ45 modular connector or a 100BASE-FX port with two SC-type fiber
connectors. Both types of connector plug into the Comm Card ports on the back of the
meter.

NOTE: IEC 61850 and COMTRADE require that your meter have an Ethernet
connection.

The optional Ethernet port:

• is capable of data rates up to 100 Mbps

• supports TCP/IP, ION, Telnet, DNP 3.00, Modbus/TCP, SNMP, FTP and IEC 61850
protocols

• is controlled by the ETH1 Communications module.

NOTE: If you have multiple simultaneous Ethernet connections to a meter, you may
need to adjust your workstation’s timeout settings to account for the high volume of
traffic.

The meter’s optional internal modem can be readily used in most countries, and
complies with FCC, Industry Canada and European regulations — refer to the Notices
at the beginning of this document for more details.

Modem connections are made to the Comm Card on the back of the meter, via an RJ11
connector.

To enable communications through the meter’s internal modem, you must configure the
Comm 3 Communications module. The Baud Rate, Unit ID, and Protocol setup
registers must properly match your system, and the initialization string for the internal
modem must be set up using the ModemInit register. See “Modem Communications
Setup” on page 91 for details.

7EN02-0248-08 85

Configuring Meter Communications ION7550 / ION7650 User Guide

Configuring Meter Communications

Communication settings are typically configured when the meter is initially put into
service. A single Communications module controls each communications port on the
meter. The modules’ setup registers define the parameters used for each port; these
parameters vary according to the type of communications channel selected (i.e. RS­232, RS-485, Modem, Optical, Ethernet).

The Communication modules control the following channels:

Module Name Settings

Comm 1 Selectable RS-232 or RS-485 port on COM1

Comm 2 High-speed RS-485 port on COM2

Comm 3 Optional internal modem on COM3

Comm 4 Optical port on COM4

Ethernet Optional 10BASE-T/100BASE-TX or 100BASE-FX Ethernet port

Use the meter’s front panel or ION Setup to initially configure the meter’s
communications. Once communication is established, Vista, Designer or the WebMeter
internal web server can also be used to modify meter communications.

NOTE: Altering the settings of a communications channel that is in use can cause a
loss of communications with the meter.

See the Communications module description in the ION Reference for complete details
about all the setup registers in the Communications module.

Communications protocols

By default, all communication ports are configured to use the ION protocol. Using other
protocols requires configuration of the Protocol setup register for the Communications
module that controls the port you want to use. Not all protocols are available on all ports.

Available protocols

• ION

• Modbus RTU and Modbus Master

• DNP V3.00

• GPS

• EtherGate

• ModemGate

• SNMP (this TCP/IP protocol is not set with the Protocol register)

• IEC 61850 (this TCP/IP protocol is not set with the Protocol register)

• Factory (reserved for use by Technical Support)

Serial Communications Setup

Serial communications are available on COM1, COM2, COM3 and COM4. To enable
communications through the meter’s serial ports, configure the applicable
Communications module. The Protocol, Tran Delay, Baud Rate and Unit ID setup
registers must properly match your system and can be set through the meter’s front
panel or ION software.

86 7EN02-0248-08

ION7550 / ION7650 User Guide Serial Communications Setup

Meter network configuration and Power Monitoring Expert

After you have wired your meter to the Ethernet network and performed basic setup,
add the meter to your Power Monitoring Expert network using the Management
Console.

See the Management Console section in the online Power Monitoring Expert Help for
details.

The EtherGate protocol

The EtherGate protocol is a communications tool that lets you communicate to a meter
and through a meter simultaneously. When a meter installed on the Ethernet network
has EtherGate enabled, a master device (such as a workstation running Power
Monitoring Expert software) can communicate to the meter, and through the meter to a
serial network of devices wired to the meter’s COM port. EtherGate is available on

90 7EN02-0248-08

ION7550 / ION7650 User Guide Modem Communications Setup

serial ports COM1 and COM 2. The protocol permits the direct transfer of data from up
to 62 devices (31 devices per COM port).

Each device in the
serial network must
have a unique Unit
ID and operate at
the same baud rate.

Ethernet

Specifying the TCP/IP Port
instructs the ION gateway
meter to:
7801—talk through COM1
7802—talk through COM2

Once you have the chain of serial devices installed, use ION Setup or the meter’s front
panel to change the COM1 or COM2 Protocol setting to EtherGate. The transfer of data
between protocols is then handled automatically.

See the ION Meter as an Ethernet Gateway technical note for complete details on
configuring your meter for EtherGate.

The meter as a Modbus gateway

The meter can function as a Modbus gateway. For more information, see “The Meter
as Modbus Gateway” on page 108.

Communicating via SNMP

The meter can communicate specified parameters via SNMP over the Ethernet. For
more information, see “Using SNMP” on page 118.

Modem Communications Setup

See “Serial Communications Setup” on page 86 for configuring COM3. Additional
modem configuration requirements are explained in the following sections.

ModemInit setup register

The ModemInit string register defines the initialization string for the internal modem,
with a maximum of 47 characters. Edit the ModemInit register and enter the initialization
string desired. The string is sent to the modem as soon as you download the COM1
module. Note that the string is also sent to the modem whenever the meter is powered
up, or whenever the baud rate in the Comm 1 Communications module is changed. Any
changes to the Modem Init or Baud Rate setup registers while the modem is online
causes the modem to disconnect from the phone line.

Modem initialization strings

See the Modem AT Commands technical note for a complete list of AT commands for
your modem.

connected to the telephone network, the Comm 3 module can be configured using the
meter’s front panel or ION software. To learn how to connect the internal modem to the
telephone network, consult your meter’s Installation Guide.

Adding a meter and a modem site to your Power Monitoring Expert network

In the Management Console, add the meter with the internal modem, and then add a
modem site to your Power Monitoring Expert network.

Consult the online Power Monitoring Expert Help for details on commissioning the ION
network, managing modem connections, setting up periodic dial-out, and configuring
remote site event notification.

The ModemGate protocol

The ModemGate feature creates a communications connection between the telephone
network and an RS-485 serial network of devices. When you specify the protocol for a
meter’s COM port as ModemGate, all data received by the meter’s internal modem is
automatically transferred to the serial network. ModemGate is available on either
COM1 and COM2, but you cannot use the protocol on both ports simultaneously.

Telnet and HyperTerminal

You can access certain Ethernet settings and statistics through a telnet application such
as Microsoft Telnet. Similarly, you can use Windows HyperTerminal to access certain
meter module settings. Use the following guidelines to determine which application you
should use to access your meter:

• If your meter is connected to an Ethernet network, use a telnet application such as
Microsoft Telnet.

• If your meter is connected serially or through a modem to your workstation, use a
terminal application such as Windows HyperTerminal.

You can access certain Power Meter module and Factory module settings from both a
Telnet session and HyperTerminal session. Both sessions also let you configure
Factory module setup registers for Current Probe Input applications. Additionally, a
Telnet session lets you view Ethernet statistics and access certain Ethernet
communications module settings.

Meter FTP server

See the Telnet and HyperTerminal Access technical note for the appropriate
application’s menu options and connection instructions.

The meter can function as an FTP server, supporting IEC 61850 protocols and
COMTRADE formatted waveform files. The FTP timeout period is 90 seconds on a
control port. Only one simultaneous FTP transfer connection is permitted. To connect
to your meter, ensure that your FTP software is configured to only use a single FTP
connection. The recommended FTP software is Windows Explorer or WinSCP running
on a Windows-based machine.

NOTE: To connect to your meter using Windows Explorer, you must include the login
and password in the FTP connection string. For example, with standard meter security
(no user configured) and the a front panel password of 2, to connect to a meter with an
IP address of 123.45.6.78, the Windows Explorer connection string would be ftp://
0:2@123.45.6.78.

The meter communicates via FTP on the following ports:

Syslog ION7550 / ION7650 User Guide

FTP folder structure

Your meter has the following FTP folder structure:

• COMTRADE: you can read COMTRADE files from these folders, but you cannot
delete or add files.

• IEC61850: you can add an IEC 61850 configuration (CID) file to this folder to
activate the IEC 61850 protocol functions of your meter.

For more information about using FTP for IEC 61850 or COMTRADE, refer to the

IEC 61850 protocol and ION Technology protocol document or the COMTRADE and
ION Technology technical note.

Syslog

Syslog is a useful feature to help maintain meter log information for extended periods
of time.

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.
Ethernet is required to use the Syslog feature.

Syslog server

Syslog is an open standard that allows you to use any one of a number of syslog server
applications currently available. The decision regarding which syslog server solution to
use is based on your budget and technical requirements. See the individual syslog
server’s documentation for more information.

Once you have the syslog server installed and configured, record the location (IP
address) of the server. This information is needed when configuring the meter’s syslog
network settings in ION Setup.

NOTE: The Syslog feature cannot be configured through the meter’s display.

Configuring Syslog network settings using ION Setup

1. Open the Setup Assistant for your meter.

2. Select Communications > Advanced Ethernet and click the SysLog tab.

3. Select Enable Syslog and click Edit. Select Yes to enable the syslog feature or

select No to disable. Click OK.

4. Select Syslog Server and click Edit. Enter the location for the syslog server. This

value is entered as an IP address in the format aaa.bbb.ccc.ddd. Click OK.

5. 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 created in the event log that informs you that the
syslog is enabled with no server IP.

Overview ION7550 / ION7650 User Guide

Overview

ION7550/ION7650 meters support DNP 3.00, Modbus RTU and Modbus/TCP,
IEC 61850 (via FTP) and SNMP protocols.

While your meter is factory configured to send data (acting as Modbus Slave), it is not
ready to receive data as a Modbus Master until you set up the necessary framework.
The meter is also pre-configured to send DNP 3.00 data to a DNP Master. IEC 61850
support requires specific configuration, refer to the IEC 61850 and ION technology
protocol document for more information.

NOTE: Changing the default factory third-party protocol frameworks (or creating new
frameworks to enable receive functionality) is an advanced procedure. Refer to the
DNP, IEC 61850 and Modbus modules descriptions in the ION Reference, as well as
the technical notes Multiport DNP 3.0 and ION Technology, IEC 61850 and ION
technology and Modbus and ION Technology before proceeding.

Most Modbus and DNP slave modules, and IEC 61850 mapping modules on the meter
are factory-set and only require basic configuration, such as communications or I/O
setup.

NOTE: Changing these modules from their factory configuration is an advanced setup
procedure that requires an understanding of the protocol, as well as an understanding
of the meter’s internal operation. For more information on your meter and these
protocols see the Modbus Protocol and Register Map for ION Devices document and
the ION7550/ION7650 DNP 3.0 Device Profile.

Communications Protocol Configuration

In order to use the factory Modbus or DNP configuration, you must first assign the
communications channel you want to use. By default, all communications ports are
configured to use the ION protocol. Select the 3rd-party protocol you want from the list
of available protocols in the Communications module’s Protocol setup register. See the
Communications chapter for instructions.

Modbus RTU is available on each of the meter’s communications ports, and multiple
ports can communicate using Modbus simultaneously. Up to three ports can use the
DNP 3.00 protocol at any one time. Additional configuration is required to enable DNP
slave functionality on multiple ports, beyond selecting the protocol on a
communications port (see the Multiport DNP 3.0 and ION Technology technical note for
more information). IEC 61850 has dedicated Ethernet communications connections,
and the IEC 61850 configuration process is detailed in the IEC 61850 and ION
technology protocol document.
