13.2.4 Technology functions
13.2.4.1 2-state controller
Function
2-state controller with feedback
Inputs
- Input
in0
target value (
setpoint
)
- Input
in1
actual value (
feedback
)
Outputs
Flag out
0,
(Menu Digital outputs, "Calculated Channel Flag")
Parameters
-
Hysteresis
-
Feedback
amplification
(Kr)
Common amplification of both parallel PT1 feedback paths
-
Feedback
time constant
1 (Tr1 ) [seconds]
PT1
time constant of negative feedback path
Tr1 < Tr2
-
Feedback
time constant 2
(Tr2 ) [seconds]
PT1
time constant of positive feedback path Tr1 < Tr2
Default
Hysteresis: 1
.
0
Tr1, Tr2: 1e38 (the feedback paths are effectively switched off)
Kr: 0.0 (feedback paths are switched off)
Exception handling
If at least one of the inputs is invalid (invalid
bit)
,
then
- the controller output is switched off (low)
- the values of the feedback paths are held
If there is doubt regarding the use of the feedback paths,
they should be left in the default settings.
