DCS控制系统与PLC控制区别
1. 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.
2. 在网络方面,DCS网络是整个系统的******，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.
