We use the PID block from Util.lib with an ABB AC500 eCo to control one of our pumps. We haven't had an issue with it before, but now when "MANUAL" is true, the output remains at 0 and doesn't push the "Y_MANUAL" value through. Any thoughts on this?

Solved. At least Kp and/or Tn need a value to push Y_MANUAL to the output, despite the controller not affecting it.

Hi, Is it possible to share an example of the PID function block ? I don't have any real device to control with the PID, is it possible to simulate the PID FB with some of simulation library. Thanks.
