■Offset/gain setting mode status flag (b10)
When registering the value, which has been adjusted with the offset/gain setting, use as an interlock condition to turn
offonoff 'User range write request' (Un\G70, b10).

■Channel change completed flag (b11)
When changing a channel to perform the offset/gain setting, use as an interlock condition to turn offonoff 'Channel
change request' (Un\G70, b11).

■Input signal error detection signal (b12)
Set 'CH1 Input signal error detection setting' (Un\G528) to one of upper lower limit detection, upper limit detection, lower limit
detection, and simple disconnection detection, and turns on if the analog input value exceeds the setting range that is set in
'CH1 Input signal error detection lower limit setting value (Un\G529) or 'CH1 Input signal error detection upper limit setting
value' (Un\G530) in the channel where the A/D conversion has been enabled. For the cases where the simple disconnection
detection is set, 'CH1 Input signal error detection lower limit setting value' (Un\G529) or 'CH1 Input signal error detection
upper limit setting value' (Un\G530) is ignored and turns on at the disconnection detection.
When 'Input signal error detection signal' (Un\G69, b12) turns on, the following operations are performed.
• Digital output value and digital operation value of the relevant channel is held with the value just before the error was
detected.
• The ALM LED flashes.
Turning off 'Input signal error detection signal' (Un\G69, b12) varies depending on Input signal error detect automatic clear
enable/disable setting.

Operations related to the turning off of input signal error detection signal (Un\G69, b12)
If the input signal is within the setting range, 'Input signal error detection signal' (Un\G69, b12) and 'Input signal error detection
flag' (Un\G40) automatically turn off, and ALM LED turns off.
