The Retrieve Data permission defines whether the user or User Group can access the actions that allow the ClearSCADA server to request data from an outstation, PLC etc. For example, if this permission is enabled on a PSTN outstation for the selected user, the user can access the One Shot action.
For more information, see One Shot in the ClearSCADA Guide to Drivers.
Availability: Can be restricted via the Permission Restrictions settings (see Define whether any Permissions are Restricted).
