DCS存在的疑问

　　(1)1对1构造。1台外表，1对传输线，单向传输1个信号。这种构造形成接线杂乱、工程周期长、设备费用高、维护艰难。

　　(2)牢靠性差。模仿信号传输不只精确度低，且易受搅扰。为此选用各种办法进步抗搅扰性和传输精确度，其结果是添加了本钱。

　　(3)失控状况。操作员在操控室既不了解现场模仿外表的作业状况，也不能对其进行参数调整，更不能猜测事端，致使操作员对其处于失控状况。因操作员不能及时发现现场外表毛病，而发作事端已层出不穷。

　　(4)互操作性差。虽然模仿外表已一致4～20mA信号规范，可大有些技能参数仍由制作商自定，致使不一样品牌外表无法交换。因而致运用户依靠制作厂，无法运用功用价格比**的配套外表，乃至呈现单个制作商垄断市场的局势。

3.DCS在中国

因中国传统产业改造和新建工程项目对DCS的急需，80年代从国外引进了几百套DCS来配备石化、冶金、电力等职业。进入90年代，中国一些新式高科技公司进入DCS范畴。现在在国内出产的DCS不只具有价格低廉、备品备件便利的优势，并且在技能**、组态学习简略、技能支撑有力等方面都取得用户必定。国内DCS出产的**商品具有体系敞开、兼容现场总线、管控一体化和带有**操控软件，在技能上可开始与国外商品相抗衡。现在，中国现场操控体系一般仍选用DCS。

DCS操控体系与PLC操控差异:DCS是一种“涣散式操控体系”,而PLC(可编程操控器)仅仅一种操控“设备”,两者是“体系”与“设备”的差异。体系能够完结任何设备的功用与和谐,PLC设备只完结本单元所具有的功用。

　　DCS网络是悉数体系的**,DCS体系通常选用的国际规范协议TCP/IP。它是安全牢靠双冗余的高速通讯网络,体系的拓宽性与敞开性非常好.而PLC由于基本上都为单个小体系作业,在与其他PLC或上位机进行通讯时,所选用的网络方法基本都是单网构造,网络协议也常常与国际规范不符。在网络安全上PLC没有极好的维护办法。

　　DCS整体思考计划,操作员站都具有工程师站功用,站与站之间在运转计划程序下装后是一种紧密联合的联系,任何站、任何功用、任何被控设备间都是彼此连锁操控,和谐操控;而单用PLC相互衔接构成的体系,其站与站(PLC与PLC)之间的联系则是一种松散衔接方法,做不出和谐操控的功用。

　　DCS在悉数规划上就留有很多的可拓宽性接口,外接体系或拓宽体系都非常便利,PLC所搭接的悉数体系完结后,想随意的添加或削减操作员站都是很难完结的。

　　为确保DCS操控的设备的安全牢靠,DCS选用了双冗余的操控单元,当主要操控单元呈现毛病时,都会有有关的冗余单元实时无扰的切换为作业单元,确保悉数体系的安全牢靠。PLC所搭接的体系则需求配备双PLC完结冗余。

　　对各种技能操控计划更新是DCS的一项**基本的功用,当某个计划发作变化后,工程师只需求在工程师站长将更改正的计划编译后,履行下装命令就能够了,下装进程是由体系白动完结的,不影响原操控计划运转。体系各种操控软件与算法能够将技能方针的操控精度进步。

　　而关于PLC构成的体系来说,作业量极端巨大,首要需求确定所要修改更新的是哪个PLC,然后要用与之对应的编译器进行程序编译,**终再用专用的机器(读写器)一对一的将程序传送给这个PLC,在体系调试时期,很多添加调试时刻和调试本钱,并且极不利于日后的维护。
