DCS是分布式控制系统的英文缩写（Distributed Control System），在国内自控行业又称之为集散控制系统。是相对于集中式控制系统而言的一种新型计算机控制系统，它是在集中式控制系统的基础上发展、演变而来的。它是一个由过程控制级和过程监控级组成的以通信网络为纽带的多级计算机系统，综合了计算机，通信、显示和控制等4C技术，其基本思想是分散控制、集中操作、分级管理、配置灵活以及组态方便。
DCS是计算机技术、控制技术和网络技术高度结合的产物。DCS通常采用若干个控制器（过程站）对一个生产过程中的众多控制点进行控制，各控制器间通过网络连接并可进行数据交换。操作采用计算机操作站，通过网络与控制器连接，收集生产数据，传达操作指令。因此，DCS的主要特点归结为一句话就是：分散控制集中管理。
Highly integrated. There is no doubt about this, as the demand for factory intelligence continues to increase, more and more equipment and systems need to be integrated into control systems. ABB's latest 800xA system not only integrates alarm management, advanced control, video system, security, and other built-in functions, but also extends to electrical integration. And Rockwell Automation's latest PlantPAx integrates motor control functions.
Information security. The safety situation faced by industrial control systems is becoming increasingly severe, and DCS suppliers have also made great efforts in this regard. The ABB 800xA v6 version further enhances the information security performance of industrial control systems, such as access control or whitelist, monitoring and management process system security, etc. Through seamless data access, productivity, efficiency, and security levels are improved.
DCS is a highly integrated product of computer technology, control technology, and network technology. DCS usually uses several controllers (process stations) to control numerous control points in a production process, and each controller is connected through a network and can exchange data. The operation adopts a computer operation station, which is connected to the controller through a network to collect production data and convey operation instructions. Therefore, the main characteristics of DCS can be summarized in one sentence: decentralized control and centralized management.
DCS stands 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. It is a multi-level computer system composed of process control level and process monitoring level, connected by a communication network. It integrates 4C technologies such as computer, communication, display, and control. Its basic idea is decentralized control, centralized operation, hierarchical management, flexible configuration, and convenient configuration.
