1771-VHSCB
从应用对象的规模上来说。
PLC一般应用在小型自控场所，比如设备的控制或少量的模拟量的控制及联锁，而大型的应用一般都是DCS。当然，这个概念不太准确，但很直观，习惯上我们把大于600点的系统称为DCS，小于这个规模叫做PLC。我们的热泵及QCS、横向产品配套的控制系统一般就是称为PLC。
说了这么多PLC与DCS的区别，但我们应该认识到，PLC与DCS发展到今天，事实上都在向彼此靠拢，严格的说，现在的PLC与DCS已经不能一刀切开，很多时候之间的概念已经模糊了。现在，我们来讨论一下彼此的相同（似）之处。
1、从功能来说。
PLC已经具备了模拟量的控制功能，有的PLC系统模拟量处理能力甚至还相当强大，比如西门子的S7 400、AB 的Control Logix 和施耐德的Quantum 系统。而DCS也具备相当强劲的逻辑处理能力，比如我们在AC800F上实现了一切我们可能使用的工艺联锁和设备的联动启停。
2、从系统结构来说。
PLC与DCS的基本结构是一样的。PLC发展到今天，已经全面移植到计算机系统控制上了，传统的编程器早就被淘汰。小型应用的PLC一般使用触摸屏，大规模应用的PLC全面使用计算机系统。和DCS一样，控制器与IO站使用现场总线（一般都是基于RS485或RS232异步串口通讯协议的总线方式），控制器与计算机之间如果没有扩展的要求，也就是说只使用一台计算机的情况下，也会使用这个总线通讯。但如果有不止一台的计算机使用，系统结构就会和DCS一样，上位机平台使用以太网结构。这是PLC大型化后和DCS概念模糊的原因之一。
