Everything about Distributed control system

Computerized control system with distributed decision-making

A distributed control system (DCS) is a control system used to control industrial processes in which control functions are distributed among multiple autonomous controllers like Programmable Logic Controller (PLC) connected by a communication network. These controllers are typically located near the process equipment or within plant control areas, while operator interfaces, supervisory control, alarm management, and process monitoring are commonly provided through centralised operator stations. This architecture contrasts with centralised control systems, in which control functions are performed primarily by a central controller or computer system. By distributing control functions across multiple controllers, a DCS can improve system availability, scalability, and fault isolation, while reducing the amount of dedicated point-to-point wiring required for large industrial processes.
