FRER IEC61850 Configuration Manual

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:
