Searches for the first occurrence of an alarm priority and type. You can search all areas, the current area only, or specify an area to limit the search. If calling this function from a remote client, use the MsgRPC() function.
This function returns an alarm record identifier that you can use in other alarm functions, for example, to acknowledge, disable, or enable the alarm, or to get field data on that alarm.
Note: Record numbers obtained from AlarmGetDsp are not valid for this function.
When the Alarm Server is not in the calling process, this function will become blocking and cannot be called from a foreground task. In this case, the return value will be undefined and a Cicode hardware alarm will be raised.
Note: This function will return a match for an Acknowledge Off alarm with [Alarm]AckHold=1 even after it has been cleared using AlarmClear or AlarmClearRec.
AlarmFirstPriRec(Priority, Type [, Area] [, ClusterName] )
The alarm Priority or group handle of a group of alarm priorities. Set Priority to 0 (zero) to match all alarm priorities.
The type of alarms to find:
0 - All active alarms, that is Types 1 and 2.
1 - All unacknowledged alarms, ON and OFF.
2 - All acknowledged ON alarms.
3 - All disabled alarms.
4 - All configured alarms, that is types 0 to 3, plus acknowledged OFF alarms. If you do not specify a type, the default is 0.
The area in which to search for alarms. If you do not specify an area, or if you set Area to -1, only the current area will be searched.
Specifies the name of the cluster in which the Alarm Server resides. This is optional if you have one cluster or are resolving the alarm server via the current cluster context. The argument is enclosed in quotation marks "".
The alarm record identifier or -1 if no match is found. If you do not specify an area, only alarms in the current area on the alarms server are searched.
