8.2 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:
Selection/text/value
-100 to +100 (0)
0 to 100
-100 to +100
0 to 9999
0 to 9999
Y0 = 0 %
Y0 = 0 %
Y0 = 100 %
Y0 = -100 %
Product:
Temperature controller XT-T1
Description
Working point correction (in percent) for a P or PD control-
ler (correction value for the output level)
If the actual value has reached the setpoint value, the out-
put level corresponds to the working point Y0.
Admissible maximum output level (in percent; only effec-
tive if Xp > 0)
Admissible minimum output level (in percent; only effec-
tive if Xp > 0)
Minimum ON period (in seconds) to limit the switching
frequency for switched outputs
