Distributed Control System
Type of control system in which the system elements are dispersed but operated in a coupled manner.
- NOTE: Distributed control systems may have shorter coupling time constants than those typically found in SCADA systems.
- NOTE: Distributed control systems are commonly associated with continuous processes such as electric power generation; oil and gas refining; chemical, pharmaceutical and paper manufacture, as well as discrete processes such as automobile and other goods manufacture, packaging, and warehousing.
