I am trying to count how many times an alarm has occured by means of PICompFilDat and/or PIAdvCalcFilVal as described in following thread:
When I do this, I see that some events are duplicated, some are not (see Excel screenshot below; PICompFilDat).
Below I have attached some trend screenshots that show that there are only 2 events; the second event (timestamp 11-jan-18 23:14:59) seems to be duplicated somehow.
Does anyone know how this could be fixed? I think this may have something to do with tag configuration or compression settings.
