Input signal error detection flag
The status of an input signal can be checked for each channel.
b15 b14 b13 b12 b11 b10 b9
0 0 0 0 0
(1) 0: Normal, 1: Input signal error
(2) The values of b4 to b15 are fixed to 0.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
Input signal error detection flag
■Input signal error detection flag status
• When an analog input value out of the range specified in Input signal error detection setting value is detected, Input signal
error (1) is stored in 'Input signal error detection flag' (Un\G40) corresponding to each channel.
• When an error is detected in any channel where the A/D conversion and the input signal error detection are enabled, 'Input
signal error detection signal' (Un\G69, b12) turns on.
■Clearing Input signal error detection flag
• When 'Input signal error detect automatic clear enable/disable setting' (Un\G304) is set to Disable, Input signal error
detection flag turns off by turning offonoff 'Error clear request' (Un\G70, b15) after the analog input value returns to
within the setting range. When 'Operating condition setting request' (Un\G70, b9) is turned offonoff, the flag is cleared.
• When 'Input signal error detect automatic clear enable/disable setting' (Un\G304) is set to Disable, 'Input signal error
detection signal' turns off after the analog input value returns to within the setting range.

■Input signal error detection flag status
• When an analog input value out of the range specified in Input signal error detection setting value is detected, Input signal
error (1) is stored in 'Input signal error detection flag' corresponding to each channel.
• When an error is detected in any channel where the A/D conversion and the input signal error detection are enabled, 'Input
signal error detection signal' (Un\G69, b12) turns on.
■Clearing Input signal error detection flag
• When 'Input signal error detect automatic clear enable/disable setting' is set to Disable, Input signal error detection flag
turns off by turning offonoff 'Error clear request' (Un\G70, b15) after the analog input value returns to within the setting
range. When 'Operating condition setting request' (Un\G70, b9) is turned offonoff, the flag is cleared.
• When 'Input signal error detect automatic clear enable/disable setting' is set to enable, 'Input signal error detection signal'
turns off after the analog input value returns to within the setting range.
