SPECIFICATIONS
3.4.13 Warning output flag (Process alarm/Rate alarm) (Un\G47 and
Un\G48)
(1) When a measured temperature value is out of the setting range of the
CH Process alarm upper/lower limit values (Un\G94 to Un\G125) or
CH Rate alarm upper/lower limit values (Un\G134 to Un\G149), the bit
of the corresponding channel turns ON (changes to "1").
(2) For both process alarm and rate alarm, whether the warning is for the
upper limit value or lower limit value can be checked for each channel.
(3) When the measured temperature value or the change of measured
temperature values returns to within the setting range, this flag will be
automatically reset.
(4) If a warning is detected on any of channels for which conversion and
warning output of process alarm or rate alarm are enabled, Warning
output signal (XD) also turns ON.
(5) When Operating condition setting request (Y9) is turned ON, this flag
will be cleared.
