The IEC 61850 data model of the IEDs includes a logical node LD0.MMSLPRT1 for IEC 61850 vertical communication diagnostic. The counters are available via the HMI path or PCM600 path .
| Data object | Description | Diagnostic information |
|---|---|---|
| SucConnCnt | Successful connections | Number of succeeded client connection attempts |
| FailConnCnt | 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 via LHMI and via the IEC 61850 communication by writing TRUE to the RsCnt.Oper.ctlVal attribute under MMSLPRT1.
GOOSE communication has its own diagnostic counters. See the Diagnostic counters section in this manual for information on the diagnostic counters used in GOOSE communication.
