I have tags PE which set value every hour. The equation of this tag has NoOutput() function. And after recalulation for the period of time in archive set "No Sample" value. How can i recalc PE tags without "No Sample".
PI Performance Equation Recalculator requires existing archive events for the calculated tag. It recalculates new values at given timestamps. It does neither insert nor delete but recalculates values. If the equation becomes evaluated to NoOutput() the recalculator will not delete the event but set the value to "No Sample".
I want find the way to recalculate this tags by the period of time in past without set the value to "NoSample".
I am afraid there's no way. Please see known issue 7855OSI8 - Improper handling of NoOutput().
Even there was a known issue created for this behavior, the "No Sample" state makes absolute sense to me and I wonder what else you would like to see here.
