DCS与PLC的区别要点1. DCS是一种“分散式控制系统”,而PLC (可编程控制器) 只是一种控制“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网络是整个系统的中枢神经,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。 3. 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。 4. 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。 5. DCS安全性:为保证DCS控制的设备的安全可靠,DCS采用了双冗余的控制单元,当重要控制单元出现故障时,都会有相关的冗余单元实时无扰的切换为工作单元,保证整个系统的安全可靠。PLC所搭接的系统基本没有冗余的概念,就更谈不上冗余控制策略。特别是当其某个PLC单元发生故障时,不得不将整个系统停下来,才能进行更换维护并需重新编程。所以DCS系统要比其安全可靠性上高一个等级。 6. 系统软件,对各种工艺控制方案更新是DCS的一项最基本的功能,当某个方案发生变化后,工程师只需要在工程师站上将更改过的方案编译后,执行下装命令就可以了,下装过程是由系统自动完成的,不影响原控制方案运行。系统各种控制软件与算法可以将工艺要求控制对象控制精度提高。而对于PLC构成的系统来说,工作量极其庞大,首先需要确定所要编辑更新的是哪个PLC,然后要用与之对应的编译器进行程序编译,最后再用专用的机器(读写器)专门一对一的将程序传送给这个PLC,在系统调试期间,大量增加调试时间和调试成本,而且极其不利于日后的维护。在控制精度上相差甚远。这就决定了为什么在大中型控制项目中(500点以上),基本不采用全部由PLC所连接而成的系统的原因。
