The self-optimization function SO determines the optimum controller parame-
ters for a PID or PI controller.
The following controller parameters are determined, depending on the type of
controller:
Reset time (Tn1, Tn2), derivative time (Tv1, Tv2), proportional band (Xp1, Xp2),
switching cycle time (Cy1, Cy2), filter time constant (dF).
The controller selects one of two methods, a or b, depending on the size of the
control deviations:
