Detection method
Select a detection method from the following table.
Detection method Detection condition
0: Disable Input signal errors are not detected.
1: Upper and lower limit An input signal error is detected when the
detection analog input value is equal to or greater
than the input signal error detection upper
limit value, or when the analog input value
is equal to or smaller than the input signal
error detection lower limit value.
2: Lower limit detection An input signal error is detected when the
analog input value is equal to or smaller
than the input signal error detection lower
limit value.
3: Upper limit detection An input signal error is detected when the
analog input value is equal to or greater
than the input signal error detection upper
limit value.
4: Simple disconnection Simple disconnection detection is performed. For details, refer to the following.
