1756-EN2T A-B 以太网通信模块分散控制系统是专门为工业过程控制设计的过程仪表控制系统，也称为集散控制系统。按照可编程控制器的发展历程和DCS发展历程的分析，分散控制系统的主要应用场合是连续量的模拟控制，而可编程控制器的主要场合是开关量的逻辑控制。因此在设计思想上有一定的区别。
在工厂自动化或计算机集成过程控制系统中，为了分散危险和分散功能，采用分散综合的控制系统结构。可编程控制器是分散的自治控制系统，它可以作为下位机完成分散的控制功能，与直接数字计算机的集中控制比较有质的飞跃。这种递阶控制系统也是分散控制系统的基础。

The 1756-EN2T A-B Ethernet communication module decentralized control system is A process instrument control system specially designed for industrial process control, also known as distributed control system. According to the analysis of the development of programmable controller and DCS, the main application of distributed control system is continuous analog control, and the main application of programmable controller is the logic control of switching quantity. Therefore, there are certain differences in design ideas.
In factory automation or computer integrated process control system, in order to disperse risk and disperse function, a decentralized integrated control system structure is adopted. Programmable controller is a decentralized autonomous control system, which can be used as a subordinate computer to complete decentralized control functions, and has a qualitative leap compared with the centralized control of direct digital computer. This hierarchical control system is also the basis of decentralized control systems.
