2) To detect input signal errors at an upper limit value only
• Input signal error detection extended setting: 1 (different upper/lower limit
values)
• Input signal error detection upper limit setting value: 100 (10.0%)
• Input signal error detection lower limit setting value: 251 (input signal error
detection disabled)
3) To detect input signal errors at different upper and lower limit values
• Input signal error detection extended setting: 1 (different upper/lower limit
values)
• Input signal error detection upper limit setting value: 50 (5.0%)
• Input signal error detection lower limit setting value: 120 (12.0%)
