PID Module Configuration - I/O Function Selections
(1) Control Register+56: Input CH0 Function
The one of the following input functions can be selected as the Input CH0 Function.
Input CH0:
Input CH0 is used as the process variable (PV) for CH0 control.
Difference (CH0-CH1):
The difference between input CH0 and input CH1 is used as the process variable (PV) for CH0 control.
Process variable (PV) of CH0 control = Input CH0 input value - Input CH1 input value
Difference (CH1-CH0):
The difference between input CH1 and input CH0 is used as the process variable (PV) for CH0 control.
Process variable (PV) of CH0 control = Input CH1 input value - Input CH0 input value
Addition (CH0+CH1):
The addition of input CH0 and input CH1 is used as the process variable (PV) for CH0 control.
Process variable (PV) of CH0 control = Input CH0 input value + Input CH1 input value
