為保證dcs控制的設(shè)備的安 全可靠,dcs采用了雙冗余的控制單元,當(dāng)重要控制單元出現(xiàn)故障時(shí),都會(huì)有相關(guān)的冗余單元實(shí)時(shí)無擾的切換為工作單元,保證整個(gè)系統(tǒng)的安 全可靠。plc所搭接的系統(tǒng)則需要配置雙plc實(shí)現(xiàn)冗余。
對各種工藝控制方案更新是dcs的一項(xiàng)最基本的功能,當(dāng)某個(gè)方案發(fā)生變化后,工程師只需要在工程師站長將更改過的方案編譯后,執(zhí)行下裝命令就可以了,下裝過程是由系統(tǒng)白動(dòng)完成的,不影響原控制方案運(yùn)行。系統(tǒng)各種控制軟件與算法可以將工藝對象的控制精度提高。
而對于plc構(gòu)成的系統(tǒng)來說,工作量極其龐大,首先需要確定所要編輯更新的是哪個(gè)plc,然后要用與之對應(yīng)的編譯器進(jìn)行程序編譯,最后再用專用的機(jī)器(讀寫器)一對一的將程序傳送給這個(gè)plc,在系統(tǒng)調(diào)試期間,大量增加調(diào)試時(shí)間和調(diào)試成本,而且極不利于日后的維護(hù)。
在控制精度上相差甚遠(yuǎn)。這就決定了為什么在大中型控制項(xiàng)目中(500點(diǎn)以上),基本不采用全部由plc所連接而成的系統(tǒng)的原因dcs系統(tǒng)所有i/o模塊都帶有cpu,可以實(shí)現(xiàn)對采集及輸出信號品質(zhì)判斷與標(biāo)量變換,故障帶電拔,隨機(jī)更換。而plc模塊只是簡單電氣轉(zhuǎn)換元,沒有智能芯片,故障后相應(yīng)單元全部癱瘓.
