PID in zLogic?

PID in zLogic?

Hi all...

I would like to know, did someone use PID control in zenon logic?
What is th menaning of DEADBAND_Error parameter?
Here is Deadband in relation with PV an previous PV... (PVPrev-DB < PV < PVprev+DB) error stays the same as in prev. cycle?
What is FFD parameter?

How to make standard functionality for deadband like:
Error = SP-PV
If abs(Error) < deadband,
Error is 0,
PID Output = unchanged,
else
PID Output = PID calculated,
end if
