    PLEASE VOTE ON USERVOICE: Event Frame End Trigger Time True Functionality – Customer Feedback for OSIsoft & the PI System


    On slightly noisy signals (i know, i could fix the source), the "StartTrigger true for" functionbality is very handy to only start an EventFrame when the trigger is stable.

    However, i have the same issue at the other end. I would like to have same functionality for the End Trigger...

     

    Now i have to find a way to build that in the Trigger condition, and that is not very easy... E.g. having a 5-second delay, one could look at the last time the trigger was true or false (e.g. using FindEq), but that should not look before the time of the start condition as that gives me EventFrames with a duration of zero.... Complicated....

     

    What would help too is having access to the current EventFrame, e.g. %StartTime% within the Analytics expression, or other attributes of the EventFrame to build the EndTrigger logic on. Of course the start trigger logic cannot use that, as there is no current EventFrame before it is started...
