Difference between the PID controllers

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.
