Event Attribute Object Extension in Object Type Structure can't read Event Attributes defined in Library Structure
We have in our earlier projects used IEC61850 MMS communication between our switchgear relays and our IEC61850 OPC Server (CET). The alarms come with class 0, and therefore we have used a workaround to add classes to our alarms from IEC61850. In the IEC61850 Alarm Collection Definition (made in Library Structure when the IEC61850 Event Collector in Service Group is uploaded) we've added a new Event Attributes Definitions working as an extension, with a class, to the ProcessConditionDiscreteEvent event attribute.
In Object Type Structure we've then added a Event Attribute Object Extension aspect under the IEC61850 bay module, and in this aspect selected the ProcessConditionDiscreteEvent. This gives us the possibility to set a class for the alarms in each bay module in the Control Structure.
As earlier said, this has worked in earlier projects. Now, when we try to read the Event Attributes Definitions in the Event Attributes Object Extension aspect added in the Object Type Structure, are each Event Attribute just blank. Please see attached document which shows before and now.
To your information are we now using 800xa version 6.x and on the projects were this workaround worked, we used 800xa version 5.x.
Thanks for answers.
after creating your own event attribute definitions under library str to the concerned alarm collection group.
then add the event atribute object extension aspect under any object/network level then select the object with descedents and select the object category then add the event atrribute with value for the attributes u have created in the lib str.
