SIEMENS Distributed Control System (DCS) is known as process control system (PCS), is a digitally working industrial control system (ICS) that controls distributed control loops in industrial plants or machines. It fulfills the tasks of process control technology.
A distributed control system differs from a central control system in that each individual control circuit can carry out its own control. The individual control circuits are self-sufficient and connected to one another via a communication network.
Process control systems are used to control industrial processes and improve their safety and reliability. They are used in many industrial systems. In chemical production processes and in petrochemical plants, in electricity and nuclear power plants, in food production and in water treatment plants and in many other industrial facilities. The process control system is functionally comparable to the network control system SCADA, in which data is recorded, saved and analyzed in real time . Both concepts work with a remote control center. Process control systems must be real-time capable, as well as high availability ensure and support the interoperability of different components.
