DCS SUPER EASY Explained
A distributed control system (DCS) is a digital automated industrial control system (ICS) that uses geographically distributed control loops throughout a factory, machine or control area. Unlike a centralized control system that operates all machines, a DCS allows each section of a machine to have its own dedicated controller that runs the operation. A DCS has several local controllers located throughout the area that are connected by a highspeed communication network. While each controller works autonomously, there is central supervisory control run by an operator.

DCS are used to control industrial processes and increase their safety, costeffectiveness and reliability.

DCS are commonly used in serval processes, including:

Agriculture
Chemical plants
Petrochemical (oil) and refineries
Nuclear power plants
Water treatment plants
Sewage treatment plants
Food processing
Automobile manufacturing
Pharmaceutical manufacturing
A DCS includes both software and hardware elements. Installation costs are minimized by the simplicity of local installation with most controllers. Reliability is improved by onsite, lowlatency automated control; human oversight is enabled for central control functions and remote control options. Individual processes have their own controllers with separate CPUs, so other processes can continue in an individual failure situation, unlike a central controller system.
