Analysis does not write final result into PI point


I made elapsed working time calculation for process equipment in AF analysis.

Problem is writing a final result (time in seconds) into PI point.


ON/OFF triggering working fine, and when i manually test result shall be recorded.

But when it is started and stopped automatically (amperage) result is not written.

Maybe is a reason long elapsed time (500+ hours), but it's very strange.



‘Status’ in amperage (0 – OFF, >0 – ON)


Final result

IF BadVal('WorkingTime') then 0 else (IF (('Status' = 0) AND (PrevVal('Status','*') > 0)) THEN Int('*'-NextEvent('Status',FindEq('Status',PrevEvent('Status',PrevEvent('Status','*')),'*-1h',0))) Else NoOutput())


Condition BadVal('WorkingTime') is because when I create a new element from template displayed value is Calc Failed.


Unfortunately, I don't have latest event frames version to solve problem of writing final values into PI point.

Do you have an idea how to solve this?
