Alarms and events

You can create AVEVA OMI and InTouch HMI applications that generate alarms and events to provide the status of a running application.

Application objects include built-in event and alarming reporting capabilities. You must configure alarms and events in the IDE object editor to use the event and alarm functions.

Application Server supports the following types of alarms:

• State alarms, which are also known as Boolean alarms. See State alarm for more information.

• Limit alarms. See Limit alarms for more information.

• Target deviation alarms. See Deviation alarm for more information.

• Rate of change alarms. See Rate of change (ROC) alarm for more information.

• Bad value alarms. See Bad value alarm for more information.

The types of alarm that you can configure are based on the data type of the attribute’s value.
