I've seen some similar questions in the past years but, no definitive answer. Since 800xA 6.0 PLCC alarms come with OPC Source Name (Controller : Parent Object Name . Object Name) instead of Object Name only as in 5.1 and before.
I've tried playing with Alarm Owner (unchecked in the Controller and Parent object and, checked into the Object itself) but still the same.
Is there any update on how to make the alarms list show only Object Name?
