III-16.8
PIDMA (Control function with particular self-tuning behaviour (No. 93)
The controller block PIDMA is particularly suitable for difficult processes (with delay time, or of higher order). The dif -
ference between PIDMA and the CONTR block is only in the PID controller kernel (self-tuning and control algorithm).
The additional functions ramp, switchover, override control, feed-forward control etc., which are described in the
CONTR section, are not different.
