Dear PISquare members,

I would like to develop a PI Analysis which returns the time tf where a condition has been true for 30 minutes since a start time t0.

Below is the graph which describes what I mean:

How could I do this ?

Thanks,

Best regards,

Nicolas

You will face some challenges using Expression Analysis with regards to scheduling even though the TimeEq function can be used. You might need to configure a small interval as periodic scheduling e.g. 1 min but your results will only be accurate to the nearest minute.

If you use an Event Frame Generation Analysis, then you can set the Trigger as 'Condition'=1 for a Time True of 30 mins. The scheduling used can be Event-Triggered. The start time of the Event Frame that is generated will be the tf that you are looking for. This result will be more precise.
