Hello,
I have a PID block in my program controlling pump speed in order to get a correct Differential pressure.
The way I have it set up is the current DP is reading into the PV on the PID block. The DP is accurate and moving. The issue is, when I go into my PID setup screen the PV always reads 0. Which as you could probably understand is really throwing everything off. I do have a UL flag thrown which I am also trying to figure out but I don't think that should have anything to do with the PV.
