Specifies alarm generation conditions and output destinations. When the conditions specified here
are met, an alarm is output from the alarm output terminal (specify the output destination number
for each channel).
With "Hold Generated Alarm" set to "Hold", the alarm status is maintained after the conditions are
met once even if they do not continue to be met (Press the CURSOR key to clear the alarm).
See the next page for the condition setting for each channel.

for if the start side source setting is other than Off).
Data capture is enabled only in this interval.
Data is actually captured in this interval.
