Closed in Alarm or Open in Alarm
When Close in Alarm is set, the alarm output function's status will be output
as-is. When Open in Alarm is set, the alarm output function's status will be
reversed before being output.
The alarm output will be OFF (open) when the power is interrupted and for
about 3 seconds after the power is turned ON, regardless of the Close in
Alarm/Open in Alarm setting.
Note
This parameter can be set only when operation is stopped.

Alarm Delay
Delays can be set for the alarm outputs.
ON and OFF delays can be set for each alarm and also reflected in the com-
munications status. The alarm's ON delay will also operate when the power is
turned ON or a software reset is performed.
Note
This parameter can be set only when operation is stopped.
