Problem with alarms comming from IEC61850 OPC server (CET) not latched in alarm list
We have a project where we are communicating via IEC61850. The IEC61850 communicaiton is communicated to 800xa through IEC60850 OPC server (Communication Engineering Tool). All signals are communicated from Schneider P139 relays to 800xa without problems.
Though we have some problems with the alarms generated in CET and shown in the 800xa process alarm list. Normally these alarms needs to be acknowledged and be in the RTN state before they disapears from this alarm list, but for all the IEC61850 alarms, they disappears as soon as they enter a RTN state, even when they are not acknowledged.
It is the first project where we are using 800xa version 6.x, and on all other projects where we have used 800xa version 5.x, we have not experienced this kind of problems.
Have anyone experienced this problem before, and/or have a solution to fix this problem?
Thanks in advance.
