Description
Alarm output function
Six alarm outputs are available (if DIO1 is not used). Each of these six output points
can be assigned alarm detection (high limit, low limit, high-high limit, and low-low limit).
If multiple alarm detections are assigned to one alarm output, AND or OR connection
can be set. The direction of contact action at occurrence of alarm can be set as open or
closed in the event of an alarm.

ASWn: There are eight digits where “0” or “1” is set, which correspond to PH1, PL1,
HH1, LL1, PH2, PL2, HH2, and LL2 from the left.
“0” means no alarm output, while “1” denotes that alarm output is provided.
To output PL1, set these digits to “01000000”. To output PH1 and PL1, set
them to “11000000”. If multiple alarm detections are assigned to one alarm
output, connect these contacts in AND or OR connection.
ANORn: If multiple alarm detections have been set to ASWn, set AND or OR
connection using this parameter. (If only one alarm detection is set to ASWn,
it is not necessary to set ANORn.)
DOnD: Sets the direction of contact action in the event of alarm output.
OPN: Open if an alarm occurs (NC: Normally closed)
CLS: Closed if an alarm occurs (NO: Normally open)
