A Distributed Control System (DCS) is a type of automated control system used in industrial processes. It consists of multiple controllers distributed throughout a facility, allowing for localized control of various operations. This setup enhances reliability and flexibility, as each controller can operate independently while still communicating with a central system. DCS is commonly used in industries such as oil and gas, chemical manufacturing, and power generation. By distributing control functions, a DCS can manage complex processes more efficiently, improving overall performance and safety while reducing the risk of system failures.
