I'm trying to use the Controlle_PID from the ControlLoopLibrary 184.108.40.206.
How is it possible to reset the KI action?
Once the SP and PV are the same the output of the controller stilla shows a value. If I set to 0 the KI value the output goes to 0. Attached the Controller_PID user in a ladder program with an output value and with SP and PV that are the same.
Well, that's how a PID works.
The integral action charges up in order to sustain the PV value: when the error is zero, derivative and proportional action are zero, and the only thing that keeps the process value from going back to its equilibrium is the integral action.
