Rakesh,
Real quick off the top of my head something like this in a CALC block should
work. I'd give it a try, but our whole system is down for annual maintenance.

OUT RO01; = Difference

Subject: [foxboro] CALCULATING CHANGE IN VALUE
Hi,
I want to make a calculation where the result would be the subtraction of
current real value and value of the signal 2 minute before. How to do that ?
how to capture the value 2 minute before ?
Using IACC.
Thanks in advance.
Regards,
Rakesh
