AlarmSumNext
This command is deprecated in this version of CitectSCADA. Use the AlmSummaryNext command instead.
Gets the index of the next alarm summary entry, that is, the entry that occurred later than the entry specified by Index. You can use this index in the AlarmSumGet() function to get field data from an alarm record, in the AlarmSumSet() function to change the existing data in that record, or in the AlarmSumDelete() function to delete the record.
You can use this function to work with a series of alarm summary records. Call the AlarmSumFirst() or AlarmSumFind() function to get the index, and then call AlarmSumNext() within a loop, to move forwards in the alarm summary.
You can also get the index of an entry as soon as it displays on the alarm summary. Alarm summary entries are recorded with the most recent entry at the end of the list. Call AlarmSumLast() to get the index for the most recent entry, and then call AlarmSumNext() to get the index for the next entry that occurs.
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.
