describe
High reliability. Due to the decentralized implementation of system control functions by DCS on various computers, the system structure adopts fault-tolerant design, so the failure of one computer will not lead to the loss of other system functions. In addition, due to the relatively single task undertaken by each computer in the system, specialized computers with specific structures and software can be used for the functions that need to be implemented, thereby improving the reliability of each computer in the system.
Openness. DCS adopts an open, standardized, modular, and serialized design. Each computer in the system communicates through a local area network to achieve information transmission. When it is necessary to change or expand system functions, new computers can be easily connected to or removed from the system communication network, almost without affecting the work of other computers in the system.

DCS is the English abbreviation for Distributed Control System, also known as Distributed Control System in the domestic automation industry. Compared to centralized control systems, it is a new type of computer control system that has developed and evolved from centralized control systems.
The system mainly consists of on-site control stations (I/O stations), data communication systems, human-machine interface units (operator station OPS, engineer station ENS), cabinets, power supplies, etc. The system has an open architecture and can provide multi-layer open data interfaces. The hardware system has high reliability, convenient maintenance, and advanced technology in harsh industrial environments. The underlying Chinese software platform has powerful processing functions and provides the ability to easily configure complex control systems, as well as the support ability for users to independently develop specialized advanced control algorithms; Easy to configure and use. Support multiple fieldbus standards to meet future expansion needs. The design of the system adopts appropriate redundant configuration and self-diagnosis function up to the module level, with high reliability.
