Example setpoint sensor
The following signal types are available for the type of use "Setpoint controller":
Setpoint sensor signal types:
0 – 10 V: Voltage range of 0 – 10 V for transfer of setpoint values.
2 – 10 V: Voltage range of 2 – 10 V for transfer of setpoint values. Cable break is de-
tected for a voltage below 2 V.
0 – 20 mA: Electric current range of 0 – 20 mA for transfer of setpoints.
4 – 20 mA: Electric current range of 4 – 20 mA for transfer of setpoints. Cable break is
detected for a electric current below 4 mA.
NOTICE
The substitute setpoint is adjusted in the event of cable break detection.
For the signal types "0 – 10 V" and "0 – 20 mA", a cable break detection with a
parameterisable threshold can be optionally activated (see "Setpoint controller con-
figuration").
Setpoint sensor configuration
Function
For example, index circuit evaluator.
Use analogue input as actual value input for tem-
perature sensor.
For example for control mode T-const
Use analogue input as actual value input for PID
control.
