Difference between the PID controllers in a Schneider PLC

[Frank_T]

Hello,


Do you know what is the difference between the PID controllers PIDFF, PID1 and PIDP1 in a Schneider PLC?


I have to modify a PLC program with a new standard of coding. The new standard use a PIDFF function bloc.


If I change a PID1 bloc for a PIDFF bloc, can I use the same parameters Kp, Ti, Td?


If I change a PIDP1 for a PIDFF bloc, can I use the parameters Ki and Kd to calculating Ti (ti=1/Ki) and, Td (Td = Kd)?


Thanks you for your help.

Welcome to forum.

Is this homework or work?

You should look pid block structure, and if equation of blocks differs.

Pidff can configured either to paraller or mixed structure.
