描述
值得注意的是PLC和DCS這些原來(lái)處于不同硬件平臺(tái)的系統(tǒng)，正隨著計(jì)算技術(shù)、通信技術(shù)和編程技術(shù)的發(fā)展，趨向于建立同一硬件平臺(tái)，運(yùn)用同一個(gè)操作系統(tǒng)、同一個(gè)編程系統(tǒng)，執(zhí)行不同的DCS和PLC功能。這就是真正意義上的EIC三電一體化?；蛘哒f(shuō)DCS和PLC的形態(tài)將會(huì)變化，而它們的功能依然存在。其中的關(guān)鍵技術(shù)應(yīng)該是嵌入式PC系統(tǒng)及支持現(xiàn)場(chǎng)總線的I/O （硬件） ，以及以IEC 61161-3為基礎(chǔ)的編程系統(tǒng)及強(qiáng)實(shí)時(shí)(hard real-time)操作系統(tǒng)。PLC在中國(guó)的發(fā)展在中國(guó)，大約從1974、75年在北京和上海開(kāi)始開(kāi)發(fā)采用位片式微處理芯片的可編程順序控制器，并有所應(yīng)用。但一直未能形成批量生產(chǎn)。在改革開(kāi)放剛起步的1979年，在當(dāng)時(shí)的機(jī)械部?jī)x表局的推動(dòng)下，開(kāi)始從美國(guó)MODICON引進(jìn)起584的PLC，并首先在電站的輔機(jī)如輸煤、除灰除渣、水處理系統(tǒng)以及水泥廠等控制系統(tǒng)中成功應(yīng)用，從而大大推動(dòng)了PLC在我國(guó)工業(yè)的大規(guī)模運(yùn)用。遺憾的是，花了很大一筆外匯的這個(gè)項(xiàng)目并不曾形成良性的有后續(xù)的發(fā)展。自1985年開(kāi)始，小型PLC首先是日本三菱電機(jī)公司的MELSEC-F，通過(guò)非政府渠道進(jìn)入中國(guó)市場(chǎng)。不到三、四年時(shí)間，小型PLC就形成了大面積的推廣應(yīng)用局面。1990年以后，Siemens、Allen Bradley以及其它知名品牌開(kāi)始大舉進(jìn)入中國(guó)市場(chǎng)，占據(jù)中、大型的PLC的較大份額。1995年后形成了大型PLC以歐美為主、中型PLC歐美和日本平分秋色、小型PLC則以日本為主、Siemens也步步緊逼的格局。至今沒(méi)有很大改變。
