The GetAlarmSummary service is used to retrieve a list of active alarms in a device. The execution of this service is implemented using two Tags. The GetAlarmSummaryCommand Tag is used to trigger this service and the GetAlarmSummaryResult Tag receives the result of this operation. Both Tags use a Configuration by Strings to reference a specific device.

The GetAlarmSummaryCommand must be configured as a write-only Tag. To start this service, write any value to this Tag.

The GetAlarmSummaryResult must be a read-only Block Tag with 3 (three) Elements, which receives a list of results. The Elements and data types are the following:

•Element 0: Object Identifier, a text value in the format <object>-<identifier>

•Element 1: Alarm State, an unsigned integer value representing the BACnetEventState enumeration

•Element 2: Acknowledged Transitions, a text value representing a sequence of bits
