MISO retrieves and directs the real time Resource Operating Mode via two Control Modes.
1) CTLM – Control mode coming from the resource (Retrieval). CTLM provides Resource status communication to MISO. Resources must change the Control Mode to match operating capabilities.
2) UMOD – Control mode the Unit Dispatch System (UDS) sends to the resource (Directive). UMOD communicates the UDS desired operating mode to the Resource.
