I have to convert a 984 program to Unity.
In the 984 are 11 PID2 loops.
In Unity I want to use PIDFF.
In which cases I have to choose between parallel or mixed mode?
Which mode, parallel or mixed, do behave more similar to PID2 of 984 Plcs?
Wich parameters, exept Parallel and mixed, do make the PIDFF more similar to PID2?
The Plc that have to be changed is controlling an existing plant and we want easy and quick starting the plant again.
On the other hand, maybe I am not right for wanting to stay similar to PID2? Maybe I should choose the mode that is better for each loop? If yes how to do that?
Thanks in advance,
Robert
