Communication

The protection relay supports a range of communication protocols including IEC
61850, IEC 61850-9-2 LE, IEC 60870-5-103, IEC 60870-5-104, Modbus
Profibus 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.
One full IEC 61850-9-2 LE stream containing both voltages and currents can be
sent. Receiving of up to four SMV streams is supported with a total of maximum
16 channels. The channels are freely configurable with the possibility to engineer
SMV stream redundancy using the voltage and current switch functions with
either another SMV stream or local measurements. The SMV stream quality along
with other Application Configuration logic can be used for switching between
measurement sources.
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 are placed on integrated optional communication
modules. The protection relay can be connected to Ethernet-based communication
systems via the RJ-45 connector (100Base-TX) or the fiber-optic LC connector
(100Base-FX).
