Hi all;

I have a problem with the
PI process book, I need to run an equation whose result is summed for
every minute; Here is the syntax: (Tagval ('flowrate','t+1m')-Tagval ('flowrate','t'))*Tagval ('density','t+1m)

In addition, I need to sum up this result for every minute until 24h achieved.

I wonder if there is any solution in PI process book using performances equation, to solve the nested series problem .

I have tried to do it in the hard way by writing all the algorithm in PI calculation range, but there was a problem of having all the equations written down.(It mentions "calcul failed " after having 18 syntax written).

Thank you so much
