DCS是一种“分散式控制系统”，而PLC只是一种(可编程控制器)控制“装置”，两者是“系统”与“装置”的区别。系统可以实现任何装置的功能与协调,PLC装置只实现本单元所具备的功能.
在网络方面,DCS网络是整个系统的中枢神经，和利时公司的MACS系统中的系统网采用的是双冗余的100Mbps的工业以太网，采用的国际标准协议TCP/IP。它是安全可靠双冗余的高速通讯网络，系统的拓展性与开放性更好.而PLC因为基本上都为个体工作，其在与别的PLC或上位机进行通讯时，所采用的网络形式基本都是单网结构，网络协议也经常与国际标准不符。在网络安全上，PLC没有很好的保护措施。我们采用电源,CPU,网络双冗余.
DCS整体考虑方案,操作员站都具备工程师站功能,站与站之间在运行方案程序下装后是一种紧密联合的关系，任何站、任何功能、任何被控装置间都是相互连锁控制, 协调控制;而单用PLC互相连接构成的系统，其站与站（PLC与PLC）之间的联系则是一种松散连接方式，是做不出协调控制的功能。
DCS在整个设计上就留有大量的可扩展性接口，外接系统或扩展系统都十分方便，PLC所搭接的整个系统完成后，想随意的增加或减少操作员站都是很难实现的。
