P922 - Minimum Sensor Level of the Control Process Variable
Range:
Description:
This parameter defines the minimum value of the sensor connected to the analog input configured for the PID
controller process variable according to its engineering unit.
✓
NOTE!
This parameter will be viewed according to the selection of the parameters for the SoftPLC engineering
unit (P510 and P511).
P923 - Maximum Sensor Level of the Control Process Variable
Range:
Description:
This parameter defines the maximum value of the sensor connected to the analog input configured for the PID
controller process variable according to its engineering unit.
✓
NOTE!
This parameter will be viewed according to the selection of the parameters for the SoftPLC engineering
unit (P510 and P511).
P924 - Value for Low Level Alarm for the Control Process Variable
Range:
Description:
This parameter defines the value below which the low level alarm will be generated for the control process variable
(A760).

✓
NOTE!
Setting it to "0" disables the low level alarm and fault for the control process variable.

It defines that the control variable source will be the value read by AI1 and viewed in parameter P916
It defines that the control variable source will be the value read by AI2 and viewed in parameter
It defines that the control variable source will be the value read by AI1 minus the value read by AI2
that is, the difference between AI1 and AI2, and viewed in parameter P916
