Source of PC
setpoint [86]
Selecting the setpoint value of the process controller.
Value
Value
Parameter Source of PC setpoint [86] (page 67) will be used as the source.
AIN1
Analog input AIN1 will be used as the PC Setpoint value source.
AIN2
Analog input AIN2 will be used as the PC Setpoint value source.
AIN3
Analog input AIN3 will be used as the PC Setpoint value source.
AIN4
Analog input AIN4 will be used as the PC Setpoint value source.
Special
The special setting Setpoint signal [40] (page 68) will be used as the source.
Setpoint value
[39]
Process controller setpoint value. Value applies if the parameter Source of PC
setpoint [86] (page 67) is set to "Value".

PC
feedback
source [92]
Process controller feedback source setting. Feedback represents the actual value of
controlled quantity. It is usually a signal from the sensor or measurement inverter.
Value
Look choises of parameter's Source of PC setpoint [86] (page 67)
Feedback [61]
Process controller feedback value. Value applies if no signal is chosen PC feedback
source [92] (page 67)..

- ÷ -
Min. setpoint
value [63]
Minimal value of the possible setpoint value range.
-
- ÷ -
Max. setpoint
value [64]
Maximal value of the possible setpoint value range.
-
- ÷ -
Dead-zone [65]
Process controller dead-zone(insensitivity) for small changes of the error value.
-
- ÷ -
Setting a non-zero dead-zone can suppress the oscillations at the PC output caused by
noise at the control error Error PC [438] (page 24), but can also cause steady-state error,
which is proportional to the value of dead-zone.
Proportional
term P [80]
Proportional gain of the process controller.
1.00
0.00 ÷ 30.00
Integration
term I [208]
Time constant of the integration term of the process controller.
10.00 s
0.01 s ÷ 600.01
s
Derivation
Time constant of the derivation term of process controller.
