DCS或TDCS 
 
    （1）分散控制系统DCS与集散控制系统TDCS是集4C（Communication，Computer， Control、CRT）技术于一身的监控技术。
    （2）从上到下的树状拓扑大系统，其中通信（Communication）是关键。
    （3）PID在中断站中，中断站联接计算机与现场仪器仪表与控制装置。
    （4）是树状拓扑和并行连续的链路结构，也有大量电缆从中继站并行到现场仪器仪表。
    （5）模拟信号，A/D—D/A、带微处理器的混合。
    （6）一台仪表一对线接到I/O，由控制站挂到局域网LAN。
    （7）DCS是控制（工程师站）、操作（操作员站）、现场仪表（现场测控站）的3级结构。
    （8）缺点是成本高，各公司产品不能互换，不能互操作，大DCS系统是各家不同的。
    （9）用于大规模的连续过程控制，如石化等。
    （10）制造商：Bailey（美）、Westinghous（美）、HITACH（日）、LEEDS & NORTHRMP（美）、SIEMENS（德）、Foxboro（美）、ABB   （瑞士）、Hartmann & Braun（德）、Yokogawa（日）、Honewell（美国）、Taylor（美）等。
