Function chart number:
Analog to the fixed frequencies (refer to Section 3.8), the PID controller has
separate programmable PID fixed setpoints. The values are defined using
parameters P2201 – P2207 and are selected using binector inputs P2220 – P2222.
The selected PID fixed setpoint is available via connector output r2224 where it can
be further processed (e.g. as PID main setpoint
3 methods are available to select the PID fixed setpoints, analog to the fixed
frequencies (Section 3.8):
Direct selection
Direct selection + ON command
Binary-coded selection + ON command
The methods are selected using parameters P2216 – P2218.
P0701 = 15
or
P0701 = 99, P2220 = 722.0, P2216 = 1
