Communication
The IED supports a range of communication protocols including IEC 61850, IEC
®
60870-5-103, Modbus
available through these protocols. However, some communication functionality,
for example, horizontal communication between the IEDs, 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 standard COMTRADE file
format. 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.
Further, the IED supports sending and receiving of analog values using GOOSE
messaging. The IED meets the GOOSE performance requirements for tripping
applications in distribution substations, as defined by the IEC 61850 standard. The
IED can simultaneously report events to five different clients on the station bus.
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.
