(1) This area is used to set whether the input signal error detection/process alarm/rate
alarm warning will be output or stopped on a channel basis.
(2) To make the input signal error detection/warning output settings valid, the
operating condition setting request (Y9) must be turned ON/OFF. (Refer to
Section 3.3.2.)
(3) By default, all channels are set to disable.

(1) If the digital output value or its varying rate falls outside the setting range set to the
CH process alarm upper/lower limit value (buffer memory addresses 86 to 117:
Un\G86 to Un\G117) or CH
addresses 122 to 137: Un\G122 to Un\G137), the warning output flag for the
corresponding channel turns to 1.
(2) For both the process alarm and rate alarm, whether the warning is for the upper or
lower limit value can be checked on a channel basis.
(3) When the digital output value or its varying rate returns to within the setting range,
the warning output flag is automatically reset.
(4) If the warning is detected on any one of the channels enabled for A/D conversion
and enabled for process alarm or rate alarm warning output, the Warning output
signal (X8) also turns ON.
(5) When the operating condition setting request (Y9) is turned ON, the warning
output flag is cleared.
