A distributed control system (DCS) is a type of automated control system that manages processes across multiple locations. Unlike traditional centralized systems, a DCS distributes control functions among various controllers, which communicate with each other to ensure efficient operation. This setup enhances reliability and flexibility, making it suitable for complex industrial processes. In a DCS, each controller is responsible for specific tasks, such as monitoring sensors or controlling actuators. This decentralized approach allows for better fault tolerance and easier maintenance. Common applications of DCS can be found in industries like oil and gas, chemical manufacturing, and power generation.
