Communication
The IED supports different communication protocols: IEC 61850-8-1, DNP 3.0, IEC
60870-5-103 and Modbus
®
. Operational information and controls are available
through these protocols. However, some communication functionality, for example,
horizontal communication between the IEDs and parameters setting, is only enabled
by the IEC 61850 communication protocol.
The IEC 61850 communication implementation supports all monitoring and control
functions. Additionally, parameter setting and disturbance file records can be
accessed using the IEC 61850-8-1 protocol. Further, the IED can send and receive
binary signals from other IEDs (so called horizontal communication) using the
IEC61850-8-1 GOOSE profile, where the highest performance class with a total
transmission time of 3 ms is supported. The IED can simultaneously report to five
different IEC 61850-8-1 clients.
The IED 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 IED can be connected to Ethernet-
based communication systems via the RJ-45 connector (100BASE-TX) or the fibre-
