STATION CONTROL SYSTEM or sometimes called MASTER CONTROL PANEL is typically located in a control house environment where a station operator(s) can overview the operation of a plant or group of machines. For example, as it may relate to a group of engine driven compressors, the Station Control Panel (SCP) communicates with the Local Unit Control Panel. The UCP would contain the PLC and send information back to the SCP via Ethernet communication or other system. The operator views a HMI with as much flexibility of control as the Client Management requires. United Controls Group has designed a variety of SCP systems for compression and power generation applications. In typical compression application the operator could stop or start a compressor train, load or unload, view the condition of the engine and compressor and station yard valves, and activate an emergency shutdown.
