The Tune Limits permission defines whether the user or User Group can access the Tune Alarm Limits action or, if applicable, the Tune M/S Alarm Limits action. They can use the pick actions to alter the alarm limits of a point (this is dependent on the configuration of the point).
Although this permission is available for every database item, it is only relevant to database points that have limits.
Availability: Can be restricted via the Permission Restrictions settings (see Define whether any Permissions are Restricted).
