Operation
On the channel where an error is detected, the last digital output value and digital operation value just before the error was
detected are stored. Also, the corresponding bit of A/D conversion completed flag (Un\G10) turns off.
When the analog input does not satisfy the condition of the input signal error detection, the A/D conversion resumes
regardless of the reset on Input signal error detection flag (Un\G49) and Input signal error detection signal (XC). (The ALM
LED remains flashing.)
Clearing input signal errors
One of the following methods for clearing input signal errors can be selected by setting Input signal error detection auto-clear
enable/disable setting (Un\G162).
■When Input signal error detection auto-clear enable/disable setting is set to Enable (0)
After the analog input value returns within the setting range, the A/D converter module arranges the following status
automatically. After the analog input value returns within the setting range, turning on and off 'Error clear request' (YF) is not
required.
• Input signal error detection flag (Un\G49) is cleared.
• Input signal error detection signal (XC) turns off.
• The ALM LED turns off.
Latest alarm code (Un\G3750) is not cleared.
After the analog input value returns within the setting range, turn on and off 'Error clear request' (YF) to clear
'Latest alarm code' (Un\G3750).
