Communication

The protection relay supports different communication protocols: IEC 61850, Modbus
and DNP3 Level 2 - all using TCP/IP. DNP3 and Modbus also support serial
communication. 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 protection relay utilizes Ethernet communication extensively for different purposes.
The exact services depend on the ordered product variant and enabled functionality.

The IEC 61850 communication implementation supports all monitoring and control
functions. Additionally, parameter setting and DFR records can be accessed using the IEC
61850 protocol. Oscillographic files are available to any Ethernet-based application in the
standard COMTRADE 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. Further, 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 simultaneously report events to five different
clients on the station bus.
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, DNP3 and
Modbus. Only one DNP3 client can be supported at a time.
