I'm trying to setup an AF Analysis to count Pumps strarts.
Analysis needs to be backfilled.
I need to count Monthly Starts
The idea is to have a trigger to detect when a pump starts (Status from "OFF" to "ON") and then write the resullt to an AF Attribute mapped to a PIPoint.
Then it will be possible to count events with NumOfChanges('Flip',BOM('*'),'*')
First expression works as expected , while the the second one not, and backfill preview shows always "0" for attribute "Flip"
Any help greatly appreciated
