Communication
The protection relay supports a range of communication protocols including IEC
61850 and Modbus
®
. 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 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,
