Acknowledging Alarms
Operators can only acknowledge alarms if you provide a way to do so. For example, you may want operators to click a push button or a flashing object on the screen. Once you decide how your operators should acknowledge alarms, you can add this feature to your pictures by adding the objects you need and writing a script. You can add such a script to an object by clicking the Acknowledge Alarm Expert on the Experts toolbar. For more information about using this toolbar, refer to the Creating Pictures manual.
If you would prefer not to use an object, you can add an Alarm Summary object to your pictures. This object lets an operator acknowledge alarms by double-clicking an alarm. You can also right-click the object's spreadsheet and select one of the following commands from the pop-up menu:
- Acknowledge (to respond to a single alarm)
- Acknowledge Page (to respond to all the alarm on the screen including Data links and animated objects
- Acknowledge All (to respond to all the alarms that match the object's alarm filter)
If you acknowledge all alarms in the Alarm Summary OCX, either from the right-click menu or from the AcknowledgeAllAlarms Expert, only one message (All Alarms Acknowledged) is sent per node. This is different from acknowledging all alarms on a 6.x node where a message is sent to the alarm services for each database block acknowledged.
