The implementation of control operations for factory processes required control panels. As a result, it required much labor and did not provide a precise result. The next step in development was to transfer all factory measurements to a central permanent industrial monitoring and control room that would act as the hub of all local panels and reduce the need for manpower; however, this did not seem very convenient because virtually every control loop has its own control management hardware. With the evolution of graphic displays and electrical processors, digital controllers were placed on an array of input and output racks. This concept gave rise to the development of a distributed control system (DCS). Over the years, the term DCS has changed from distributed control to decentralized control systems. Distributed Control System is one of the smartest systems used in factories and control centers. Each system component has its own function, such as the data management and access section, processing management, and graphic display and data collection unit. The communication between each element in the factory is done through a distributed computer, which is also called a control network. The main component of the factory is the distributed control system, which is used to make automatic decisions according to the real-time update of product information throughout the factory.
