Distributed control system
A distributed control system (DCS) is a control system for a process or plant, wherein control elements are distributed throughout the system. This is in contrast to non-distributed systems, which use a single controller at a central location. In a DCS, a hierarchy of controllers is connected by communications networks for command and monitoring.Example scenarios where a DCS might be used include: Chemical plants Petrochemical (oil) and refineries Boiler controls and power plant systems Nuclear power plants Environmental control systems Water management systems Metallurgical process plants Pharmaceutical manufacturing Sugar refining plants Dry cargo and bulk oil carrier ships Formation control of multi-agent systems
