615 series DNP3 Communication Protocol Manual

All DNP3 binary outputs support direct control at any time. Double-point objects (circuit breakers and disconnectors) also support select-before-operate controls, provided that the native IEC 61850 control objects are in SBO control model mode. A double-point control is represented with one binary output point on DNP3 even if there are two separate control relay outputs (open and close) from the protection relay.
