None (no alarm)
0=Alarm (the state must be at 0 for it to be an alarm)
1=Alarm (the state must be at 1 for it to be an alarm)

Delay

The Delay time (in seconds) determines how long the input must be outside of limits before it will be flagged as an alarm. If this value is set to 300 (5 Minutes) the reading must be in the alarm type condition continuously for 5 minutes before it will be considered an alarm.

Output

The Output is the device that will be turned on when the alarm occurs. The output is any tag, unlike in version 4, were a separate output tag data base was maintained. Click the ... button to enter or browse for a selected tag.

Link Alarm

The Link Alarm is used to allow a digital tag to operate as an enable on the alarm operation. If this is set to None, no inhibiting will take place. If this is set to a tag number, the alarm will only be monitored when the value of the linked tag is non zero (or 1 if it is a digital). The Link Alarm is normally set to an always scan digital tag, and when the tag changes from 0 to 1, the alarms tied to this tag will start to be monitored. Any number of tags can be tied to a Link Alarm tag input. Click the ... button to enter or browse for a selected tag.
