Functional Block 29: Direction of action
Here, the structure switches can be set to determine whether the output signal CO1
of PID controller1 (main controller of the cascade regulation) will be used with a
positive or negative direction of action. With a positive direction of action, the output
signal increases with increasing control difference PVd1, with negative direction of
action, it reduces (cf. Functional Block 11).
Options:
Inv. No: positive direction of action
Inv. Yes: negative direction of action
