1. GENERAL DESCRIPTION
1.1 Introduction
Some FRER meters can be optionally equipped with an integrated IEC61850 Gateway or, as an alternative, can use
an external IEC61850 / Modbus RTU Gateway.
1.2 Additional option
As an additional option, on the integrated Gateway, a Master RS485 Modbus interface can also be installed,
expanding the Gateway functionality to other meters only equipped with a Slave RS485 Modbus interface.
1.3 Available Versions
Both Gateway types, integrated and external, are available in different combinations regarding the maximum number
of meters that can be connected, the Set of available measured quantities, the number of Data Sets and Report
Control Blocks included in the default configuration, and allowed as maximum in each IED.

1.4 Special considerations regarding the measurements updating time
The IEC61850 Gateway performs 3 basic operations in sequence:
Fetching of the measurements data from the meter.
Evaluating if the measurements data have changed more than the preset deadbands and, in case, updating
the relevant Data Sets.
Sending the Reports to the subscribed clients, according to the triggering options they have chosen.
This sequence is repeated, in a cyclical way, for each meter connected to the Gateway.
The time needed to complete the sequence for a single meter, depends on many factors, but the most relevant are:

CONFIGURATION MANUAL
No. Ipm0218_3
Pag./Page 2 di/of 44
the variability of the measured quantities
the number of subscribed RCB's by the IEC61850 clients.
When the measured variables are in a steady state (they don't vary more than the deadbands), and no RCB's have
been subscribed, the time required to complete the full sequence for each meter is around 450ms.
When all the measured variables change, from cycle to cycle, more than the deadbands, then each subscribed RCB's
adds about 100ms to the sequence time for each meter.
In application where update time is a concern, the "Single Meter" version of the Gateway should be preferred to both
"4 and 6 Meters" versions, the Data Sets should be kept as few and small as possible, the deadbands should be set
as wide as possible, and the number of subscribed Report Control Blocks should be as low as possible.

2. BASIC COMMISSIONING
2.1 Introduction
Before fully configure the devices, after that the proper hardware and electrical installation have been completed (see
the installation manual and/or the terminals label for each specific product), and the devices have been powered-on,
some operations must be carried out in the following order.
2.2 What you needed
Check to have got the following items from FRER (they are in a small CD included in the package, or you can obtain
them from the FRER support):
a) "Gateway Tracker" utility installation file.
"Gateway Tracker" is an utility to identify the devices on a network, to set their IP addresses, to update them to
the latest firmware release, and to upload and download special files to and from the devices, if requested by
the FRER support.
Install it on your laptop or desktop PC.
b) Latest available firmware release.
It is recommended that the firmware of the devices is upgraded to the latest release before commissioning
them.
Note: In case of devices with firmware release lower than 3.0.0.3, this is mandatory, due to both important
performance and features improvements, and bug fixes.
Contact FRER support to be sure to have obtained the latest available firmware release: you will be asked to
specify the Gateway version (Single, 4, or 6 Meters) and the last five digits of the MAC address (you can read
them on the label of the Gateway, or by the "Gateway Tracker" Utility
You will receive from FRER support a file containing the latest firmware release, which may have a name
similar to GW1_3_0_0_3.hex (for the "Single Meter" version), to GW4_3_0_0_3.hex (for the "4 Meters"
version) or to GW6_3_0_0_3.hex (for the "6 Meters" version).
Note: In case you have different Gateway versions, be careful to use the right firmware file for the right Gateway
version, otherwise at the end of the process the Gateway will be unusable.
2.3 Settings by the front display and front panel panel push-buttons
For each meter connected to the IEC61850 Gateway (including the single one which integrates the gateway itself):
a) Enter the configuration menu (as described in the specific user manual).
b) Set the correct VT's and CT's ratios (they can also be further modified later, but this requires the repetition of
the meter configuration in the configuration Web-Server -see later on paragraph 2.5 "Operations with the
Configuration Web-Server"-).
c) Set the following communication parameters:
Device logic address: between 1 and 247.
Baud rate: 19200.
Parity: Even.
Stop bits: 1.
d) Exit the configuration menu confirming changes, if requested by the meters.
Note: All meters connected to the same Gateway must be set with the same communication parameters, except the
device logic address, which must be different for each one of them.

2.4 Operations with the "Gateway Tracker" utility
a) Start the "Gateway Tracker utility", a windows opens showing a list of Gateways connected to the local
network.
Note: The factory IP settings of the Gateways are the following:
- IP address: 192.168.1.10
- Subnet mask: 255.255.255.0
- Default gateway: 192.168.1.1
Note: The Gateways must belong to the same network broadcast domain of the PC, in order to be revealed.
Note: Always avoid wireless connections, use only connections with Ethernet cable.
b) Right click on the first Gateway of the list, and then select the menu item "IP configuration":
c) Set the addresses of your choice and press OK:
d) Repeat the same process for all the Gateways in the list.
Note: All devices must be assigned with a unique IP address, and no conflicting IP addresses can exist with other
devices on the network.
Note: The assigned IP addresses must belong to the same sub-network of the PC, otherwise the following step
"Upload image" will not work.
Note: If an IP conflict exists on the network, the following step "Upload image" may leave the Gateway unusable, to be
returned to the factory for repairing.
Note: In the following step "Upload image", after the upload of an image has been completed, the relevant Gateway
will revert to its factory default IP settings: check that these settings do not conflict with those of any other
Gateway on the network.
Note: The simplest way to avoid conflicting IP settings during these operations, is to physically connect one by one the
Gateways directly to the PC.
Note: The Ethernet port of the Gateways has no auto MDI/MDIX switching function, so you may need a crossed
Ethernet cable or you may need to connect the devices to an Ethernet port supporting the auto MDI/MDIX
switching.
e) Once you have properly set the IP addresses, right click on the first Gateway of the list, and then select the

menu item "Upload image ":
f) Select the upgrade file, containing the latest firmware release, that you have received from Frer support, and
press "Open":
g) You will receive the following warning message, and press "OK":
h) Wait that the progress bar indicating the progress status will reach the end, until you will get the following
confirmation message:
Note: After the upload of an image has been completed, the relevant Gateway will revert to its default IP settings:
check that these settings do not conflict with those of any other Gateway on the network.
i) Repeat the same process for all the Gateways in the list.
j) Re-set the correct IP addresses again, according to your needs, as shown in points b) to d).
k) Close the "Gateway Tracker" utility when done.

3. CONFIGURATION WEB-SERVER
3.1 Introduction
Each IEC61850 Gateway is equipped with an integrated Configuration Web-Server (accessible by typing its IP
address on the address bar of any web browser of your choice), used to configure some functional details of the
Gateway itself, and some behaviors of the IEC61850 protocol stack, and to monitor, in the commissioning process, the
correct operation of the system.
The following is a detailed description of all the settings, grouped by the main menu items found on the left side of the
main page.
Every settings change made by the operator, needs to be saved (by pressing the "Save" button on the page) and will
became operative after a reboot of the system (a reboot will be automatically proposed after having pressed the
"Save" button).
However, all modifications introduced in a single settings page can be "cumulated" in a single saving, and all
modifications in all pages can be "cumulated" in a single reboot, unless a change in one setting affects the operation
of another setting (this is the case, for example, when one changes the communication parameters of the serial link,
which will be used in the "Meters configuration" page to identify the meters connected to the Gateway).
Note: Some settings need to be transferred to the IID file; they are:
- IP settings
- IED name
- Deadbands
- Any change in "Meters configuration"
In this case, a new IID file must be created, which will overwrite the IID or CID file currently in use.
When a CID file is loaded in the IEC61850 Server, these settings will reflect those contained in the CID file, and
could not be modified anymore unless the server is allowed to replace the current CID file with a newly
generated IID file (see paragraph 3.2.3 "IEC61850" for further details).
Note: The Configuration Web-Server heavily interferes with the operation of the IEC61850 Server, specially with those
pages which continuously update their content (Data monitor and Device statistics): its use must be limited to
the minimum required during commissioning, and should be avoided during normal operation of the IEC61850
Server
Note: Only one session of the Configuration Web-Server is allowed at a time.

3.2 General settings
This page contains some sub-pages, they are described one by one.
3.2.1 Network
IP Configuration:
In this section the IP address, Subnet mask and Default gateway of the server can be set or, as an alternative, the
DHCP client can be enabled, which retrieves automatically these settings from a DHCP client on the network.
The factory IP settings of the Gateways are the following:
- IP address: 192.168.1.10
- Subnet mask: 255.255.255.0
- Default gateway: 192.168.1.1
Note: Since the gateway will be used as IEC61850 server, it is advisable not to use DHCP, but manually assign fixed
IP settings.
Note: IP settings affect both the IEC61850 Server operation (they will be also included in the IID file) and the
Configuration Web-server operation; therefore it is not possible to have different IP settings for the IEC61850
Server and for the Configuration Web-server.
Note: When a CID file is loaded in the IEC61850 Server, these settings will reflect those contained in the CID file, and
could not be modified anymore unless the server is allowed to replace the current CID file with a new generated
IID file (see paragraph 3.2.3 "IEC61850" for further details).
DNS:
In this section the Primary and Secondary DNS servers can be set.
Note: DNS servers are used only if the NTP is enabled, and the NTP servers are specified with their URL instead of
their IP addresses. (see next section for further details).
User-defined NTP Server
If "Use NTP" check-box is checked, at boot time and then every one hour, the date and time will be automatically
retrieved from the specified NTP servers, and the internal RTC will be adjusted accordingly.
