David, I understand this might be unrelated, but this is my first time here and I am facing commissioning deadline. I am using CONT_C in a function block. I call the FB in a Cyclic Program (OB32). when the PID is in manual I can change the Block CV by entering a manual value of 0-100%. The problem is starts when I put the loop in Automatic. It is a simple Flow control loop. As soon as I put the loop in Automatic, the loop becomes very unstable. Proportional gain is 0.1, Ti is 0 ms, PV_FAC=1. Derivative is also 0. SP=1100, PV (0-1800). ------------------------------------------------------------------------------------------ |
