Self-optimization determines the optimum controller parameters for PID or PI controllers.
The following controller parameters are defined:
The controller selects procedure a or b, depending on the size of the control deviation:

Starting self-optimization is not possible with active
level inhibit and ramp function.
Self-optimization is automatically terminated, or can be can-
celled.
