7 Parameterization
Transmission behavior
The transmission behavior (controller structure) is determined by the configuration of the pa-
rameters for the proportion band (P component), derivative time (D component), and reset time
(I component).
7.2 Controller types
Two-state controller
This controller has a switched output and can be parameterized with P, PI, PD, or PID trans-
mission behavior. 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 dif-
ferential Xd1 (working point Y0 = 0 %):
