When the analog input value out of the setting range for CH
(Un\G142 to Un\G145) is detected according to the set condition of detection method, Input signal error
detection flag (Un\G49) corresponding to each channel is turned to input signal error (1).
• When setting Input signal error detection setting (Un\G47) to Enable (0) and Input signal error detection
extension setting (Un\G27) to Disable (0)
When the analog input value out of the setting range for CH
(Un\G142 to Un\G145) is detected, Input signal error detection flag (Un\G49) corresponding to each
