3.5 Communication
The protection relay supports a range of communication protocols including IEC 61850,
IEC 61850-9-2 LE, Modbus
®
and DNP3. 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.
HSR/PRP is available in 615 series Ver.5.0 FP1 ANSI.
HSR/PRP availability depends on the product ordering information. See
the Rear communication modules chapter for information on HSR/PRP
supported COM cards.

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. 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 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 and Modbus.
