[0002] The DCS system is a distributed control system composed of multiple computers and special control software connected through a communication network. The DCS control system adopts the design principle of decentralized control and centralized management, integrating computer technology, control technology, communication technology, and graphic display technology. Functionally, it can be divided into a process control layer, an operation monitoring layer, a production management layer, etc.
