AlarmNextPriRec

AlarmNextPriRec

Searches for the next occurrence of an alarm of a specified priority and type, commencing with the specified alarm record identifier (returned from the previous search through the AlarmFirstPriRec() function). 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.

Syntax

AlarmNextPriRec(Record, Priority, Type [, Area] [, ClusterName] )

Record:

The alarm record number, returned from any of the following alarm functions:

AlarmFirstCatRec() or AlarmNextCatRec() - used to search for a record by alarm category, area, and type (acknowledged, disabled, etc.).
AlarmFirstPriRec() or AlarmNextPriRec() - used to search for a record by alarm priority, area, and type (acknowledged, disabled, etc.).
AlarmFirstTagRec() or AlarmNextTagRec() - used to search for a record by alarm tag, name, and description.
AlarmGetDsp() - used to find the record that is displayed at a specified AN, for either an alarm list or alarm summary entry. Set the sField argument in AlarmGetDsp() to "RecNo".

To store this value, use data type Int in Cicode or Long for variable tags (Long needs 4 bytes).

Priority:

The alarm Priority or group handle of a group of alarm priorities. Set Priority to 0 (zero) to match all alarm priorities.

Type:

The type of alarms to find:

Non-hardware alarms

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.

Area:

The area in which to search for alarms. Set Area to -1 to search all areas. If you do not specify an area, only alarms in the current area on the Alarms Server are searched.

ClusterName:

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 "".

Return Value

The alarm record identifier or -1 if no match is found.
