REX610 IEC 61850 Engineering Guide

The IEC 61850 data model of the protection relays includes a logical node LD0.GSELPRT1 for the GOOSE communication diagnostic. The counters are also available via the HMI path Monitoring > I/O Status > Communication > GSELPRT1 > Monitoring or PCM600 path Application configuration > Communication > GSELPRT1 > Monitoring.

It is possible to reset the GOOSE communication diagnostics counters via Monitoring > I/O Status > Communication > GSELPRT1 > Monitoring > Reset counters and via the IEC 61850 communication by writing TRUE to the RsCnt.Oper.ctlVal attribute under GSELPRT1.

Table 1. Diagnostics data objects
Data objectDescriptionDiagnostics information
FrRxCntReceived messagesWhen increasing, the protection relay is receiving GOOSE messages.
FrTxCntTransmitted messagesWhen increasing, the protection relay is sending GOOSE messages.
RxStCntReceived state changesReceived GOOSE messages with a new stNum value
RxSeqCntReceived sequence numberReceived GOOSE retransmissions or heartbeat cycle messages with a new sequence number
RxTestCntReceived frames with test bitReceived GOOSE frames with the test flag on
StWrnCntState errorsNumber of notified state number jumps
SeqWrnCntSequence errorsNumber of notified sequence number jumps
RxTmOutCntReceiver time-outsNumber of notified peer device time-outs
ConfErrCntReceived ConfRev mismatchesWhen increasing, there is a mismatch between the received GOOSE frame information and the used GOOSE configuration.
NdsComCntReceived frames with Needs CommissioningOne peer device Indicates that its configuration is not valid or up-to-date.
DSErrCntErrors in received data setReceived data are syntactically wrong, or there are less data in received data set than expected.
AlmReceiver alarmAlarm signal value connected to the event and application logic. It is active when one peer device is in time-out.
GOOSE Alarm is activated in the receiver device in certain situations.
  • Time-out
  • Configuration revision mismatch
  • Error in the received data set
  • The Needs Commissioning bit is active in the received message
