Delete Specific Events in the Aspect Server
We had to change some DSP setting in a CI867 card which caused the time synchronistaion to be lost and then crashed our PM866 controller. We have resolved the crash but when this happened the controller created a lot of alarms and events that were in the future, 2106!
We have deleted the alarms but its not possible to delete direclty from the event list. As the alarms are in the future they remain at the top of the list so not good for the operators. We have a PGIM historian so all the alarms and events are backed up so I looked at deleting the events in the Aspect server.
I did this by going to Service Structure, Event Storage, Service Definition, Special Configuration, Storage Classes, AC 100 Process Condition Event (they were all in this group) and reducing the message count from 10000 to 0.
I did this in steps to check it worked as intended. However when i got to 100 it left 101 in the list and then 10 it left 11 in the list and finally when I set it to 0 it left 1 in the list. So now I have effectively deleted them all except one which is still sitting at the top of the list.
Is there any way to open the file containing these alarms and remove the last event?
