IEC 61850-8-1 redundant station bus communication

Function description

System component for parallel

redundancy protocol

Functionality

Redundant station bus communication according to IEC 62439-3 Edition 2 is available as

option in the Customized 650 Ver 1.3 series IEDs, and the selection is made at ordering.

Redundant station bus communication according to IEC 62439-3 Edition 2 uses both ports

LAN1A and LAN1B on the COM03 module.

Select COM03 for redundant station bus according to IEC 62439-3

Edition 2 protocol, at the time of ordering.

IEC 62439-3 Edition 2 is NOT compatible with IEC 62439-3 Edition 1.

Principle of operation

The redundant station bus communication is configured using the local HMI, Main

Menu/Configuration/Communication/TCP-IP configuation/ETHLAN1_AB. The

settings are also visible in PST in PCM600.

The communication is performed in parallel, that is the same data package is transmitted

on both channels simultaneously. The received package identity from one channel is

compared with the data package identity from the other channel. If the identity is the same,

the last package is discarded.

PRPSTATUS supervises redundant communication on the two channels. If no data

package has been received on one or both channels within the last 10 s, the output LAN1-

A and/or LAN1-B are set to indicate error.
