ref relay alarms not visible
Hi Sir,
Here i attached 1 screenshot from CET for doing Iec61850 based communication. Although i am able to do the communication bu not able to represent the alarms or events generated by the relay. I think it is related to the highlighted content message "IEC61850_DSC_Inactive". but i dont know what it is.. can you help...
Thanks

Hello Yoginder:
I believe this question is related to the other one you created in the forum yesterday, am I right?
If so, I answered a few comments there. Please take a look.
Nevertheless, the failure in getting the AE messages is not due to "IEC61850_DSC_Inactive". This event type refers to the following situation: every time a protection/alarm is active (eg. Breaker Failure function, as in your screenshot), the OPC Server will create an alarm message in the list. When the situation is normalized i.e. the breaker failure signal is gone, a new event message will be created of the type "Inactive", just to inform the operator the alarming situation is not there anymore. that's why you have several "IEC61850_DSC_Inactive" in your list (screenshot), one for each normalized protection. Probably this screenshot was taken from a moment you had just established communication to the IED, right? Then the OPC Server would "more or less log all states" from all the signals that are configured to generate alarms. Please take a look of my comment in your other question and let me know if you need further support.
