Hi all, let's say i create a PI calculation expression with following formula:
expA=123+'ABC'+'DEF'+'GHI' where ABC, DEF and GHI are my process tags in PI.
then can i create another expression like following?
expB=expA+'JKL' where JKL is my another process tag.
May i know how can link my first expression into my second expression calculation like Excel spreadsheet? via VBA code?
Appreciate everyone to assist me in this matter. Thanks !
