2.5 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 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, 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
