Communication

The protection relay supports a range of communication protocols including
IEC 61850, IEC 61850-9-2 LE, IEC 60870-5-103, Modbus
DPV1 communication protocol is supported by using the protocol converter
SPA-ZC 302. Operational information and controls are available through these
protocols. However, some communication functionality, for example, horizontal
communication between the protection relays, is only enabled by the IEC 61850
communication protocol.
The IEC 61850 communication implementation supports all monitoring and control
functions. Additionally, parameter settings, disturbance recordings and fault
records can be accessed using the IEC 61850 protocol. Disturbance recordings
are available to any Ethernet-based application in the IEC 60255-24 standard
COMTRADE file format. The protection relay can send and receive binary signals
from other devices (so-called horizontal communication) using the IEC 61850-8-1
GOOSE profile, where the highest performance class with a total transmission time
of 3 ms is supported. Furthermore, the protection relay supports sending and
receiving of analog values using GOOSE messaging. The protection relay meets
the GOOSE performance requirements for tripping applications in distribution
substations, as defined by the IEC 61850 standard.
The protection relay can support five simultaneous clients. If PCM600 reserves one
client connection, only four client connections are left, for example, for IEC 61850
and Modbus.
All communication connectors, except for the front port connector, are placed
on integrated optional communication modules. The protection relay can be
