REX640 IEC 61850 Engineering Guide

The IEDs' IEC 61850 data model includes a logical node LD0.MMSLPRT1 for IEC 61850 vertical communication diagnostic. The counters are available via the HMI or PCM600 path Monitoring > Communication > MMSLPRT1.

Table 1. Diagnostic data objects
Data object Description Diagnostic information
SucConn Successful connections Number of succeeded client connection attempts
FailConn Failed connections Number of failed client connection attempts
ConcCnt Concludes Number of session concludes
TxAbtCnt Sent aborts Number of association aborts sent by server
RxAbtCnt Received aborts Number of received association aborts by server
TxRejCnt Sent rejects Number of sent rejects by server
RxRqCnt Received request Number of received client requests
FailRqCnt Failed requests Number of failed client requests
SucReadCnt Reads Number of variable reads
FailReadCnt Failed reads Number of failed variable reads
SucWrCnt Writes Number of succeeded variable writes
FailWrCnt Failed writes Number of failed variable writes
InfRepCnt Reports Number of sent reports
ActConnCnt Active connections Number of active client connections

It is possible to reset the vertical diagnostics counters via Monitoring > Communication > MMSLPRT1 > Reset counters and via the IEC 61850 communication by writing TRUE to the CntRs.Oper.ctlVal attribute under MMSLPRT1.
