6.2 Controller types
Two-state controller
This controller has a switched output and can be parameterized with P, PI, PD, or PID transmission be-
havior. The proportional band Xp must be greater than 0 for the controller structure to take effect.
If Xp = 0, the behavior corresponds to the function of limit value monitoring with switching differential Xd1
(working point Y0 = 0 %):
Influence of working point Y0 on the switching behavior:
