(5) This function is executed at every sampling processing.
(6) Perform the following procedure to use this function.
1) Set the input signal error detection setting value for the corresponding channel.
2) Enable the A/D conversion of the corresponding channel.
3) Enable the input signal error detection of the corresponding channel.
4) Turn ON the operating condition setting request (Y9).
3.2.4 Warning output function
(1) Process alarm
(a) If the detected digital output value rose to or above the process alarm upper
upper limit value or fell to or below the process alarm lower lower limit value
and entered the warning output range zone, the warning output flag (buffer
memory address 48: Un\G48) and warning output signal (X8) turn ON and
the ALM LED is lit to indicate the warning.
(b) If, after the output of the warning, the detected digital output value fell below
the process alarm upper lower limit value or rose above the process alarm
lower upper limit value and returned to within the setting range, "0" is stored
into the bit position corresponding to the channel number of the warning
output flag (buffer memory address 48: Un\G48).
The warning output signal (X8) turns OFF only when all channels return to
within the setting range.

(c) When time or count averaging is specified, this function is executed at
intervals of the preset averaging time or averaging count.
When any other A/D conversion system (sampling processing, move
averaging, primary delay filter) is specified, this function is executed at
intervals of the sampling time.
