In this diagram, a DCS system has been shown. A DCS has no central control or supervisory authority in the middle. Instead, it has multiple control loops and independent controllers that are spread across the system. It is ideal for a process or production facility with several distributed controls, hence the name. The picture also represents a typical DCS environment. It has different controllers like the plant asset management, human interface station, engineering station, etc. It helps in maintaining efficiency, mitigating losses, processing data, and making informed and smarter decisions. It is no wonder that it is the system of choice in many environments.
