The Harmony DCU interfaces directly to the process, performing all functions necessary to monitor and control the process on a stand-alone basis. Thecontroller communicates with other system nodes over the control network (Cnet). It collects process I/O, performs control algorithms, and outputs control signals to process level devices. Thecontroller also imports and exports process data from and to other system nodes, and acceptsoperator control commands through network connected workstations.
