11.6 Alarms Screen
Figure 14. Sample Alarms Screen
The Alarms screen lists all alarms that are either active or unacknowledged, and includes the
following information and selections:
• Current Alarms: The top grid displays all alarms that are either active or unacknowledged.
• Ack Alarms Button: Acknowledge all unacknowledged alarms. The button will show the
current number of unacknowledged alarms.
• History: Provides a quick way to review alarm or event history over a defined period of time.
Alarm history includes any event associated with the alarm cycle such as coming into alarm,
going out of alarm, and acknowledgment. Events include any operation interaction where
they may set a value from the HMI. Events may also encompass various other system level
events.
To review historical alarm data:
1. Select Alarms or Events.
2. After selecting Alarms or Events select the time duration. The time reflects the
amount of time from the current time backwards.
3. Click Retrieve
Click a column heading to sort the historical alarm data based on that filter (EventStamp,
AlarmState, etc.).
You may perform the following queries on retrieved historical alarm data:
• Test: Tests the connection for the alarm/event history data grid.
• Retrieve: Re-runs the query for the alarm/event history data grid.
• Cancel: Can cancel a log running query for the alarm/event history data grid.
• Write: This selection is built into the data grid but is non-functional. The alarm/event
history views are read-only on the database / Wonderware Historian side. It is
typically greyed out.
