This Status attribute is specific to DNP3 points other than DNP3 Status Points:
In addition to the above, <Update Type> Status attributes, such as Current Status, might display one or more DNP3 Driver-Specific <Update Type> Status Values.
Control attributes are only available for DNP3 output points that can be controlled from Geo SCADA Expert. If an output point is controlled exclusively by another application, no control attributes are displayed for that point (see Specify Whether an Output Point is Controlled by Geo SCADA Expert).
