Sort Button
The Sort Button tool is used to provide a way that operators can sort the alarm list by alarm priority.
Note: Sorting is different from filtering. Sorting does not eliminate alarms from being displayed in the alarm list; rather, it changes the order of the items being displayed. Filtering excludes certain entries from being displayed in the alarms list. Both filtering and sorting may be applied to the alarm list simultaneously; for example, you may filter to display all alarms that have their Area parameter configured as "East", and sort the results by alarm priority.

Note: The History alarm list cannot be sorted, as it contains a mixture of security-related events, operator control actions, and alarms.

Note: the only alarm database field by which you may sort is Priority.
The Sort Descending checkbox can be selected if you wish to sort the alarm list in descending order (i.e. with the highest priority alarms appearing at the bottom of the .
Removing a Sort
Removing sorting applied by a sort button can be completed by creating a second Sort Button Editor object. This button must have its Field Number drop-down list set to the same field as its corresponding sort button, and its Minimum and Maximum fields bust be left blank.
