Stops alarm output once the alarm condition is no longer satised.
Use this setting when you wish to output an alarm only while the alarm condition is
satised.
ON Once an alarm is outputted, maintains (continue) the alarm output until you release the
alarm manually or stop measurement.
Use this setting when you wish to maintain (continue) alarm output even if the alarm
condition is no longer satised (i.e., even if conditions have returned to normal).
• If the alarm lter ([Filter]) (p. 174) is set to [OFF]
Alarm retention will be applied to judgment results for the alarm sources you wish to
monitor.
Example: AND logic applied to U1-1 and U1-2
The satisfaction state for alarm conditions will be retained once the U1-1
alarm condition is satised. Since the state will continue to be retained even
if the U1-1 alarm condition is no longer satised, an alarm will be output
once the U1-2 alarm condition is satised.
• If the alarm lter ([Filter]) (p. 174) is set to a value other than [OFF]
Alarm retention will be applied to [ALM1] to [ALM8].
Example:
AND logic applied to U1-1 and U1-2
Alarm output will be retained only when both the U1-1 and U1-2 conditions
are satised at the same time.
