We do a rolling three hour average with a sequence block , taking a sample
once per minute. To trend the average , you need only to put the sequence
block real output into a historian and assign that value to a trend point.
If you like , I can send you a copy of the code.

Subject: [foxboro] 24 hr rolling average
I know we have already ventured down this path once but at the time rolling
average didn't interest me and I didn't give it a passing thought...now it
does.
My question is: How would you program for a 24 hour rolling average (my case
is a flow) say sampled every 5 minutes (288 samples per day)? I also need
to trend the result.
