三大控制系統(tǒng)之間的差異 

我們已經(jīng)知道，F(xiàn)CS是由DCS與PLC發(fā)展而來(lái)，F(xiàn)CS不僅具備DCS與PLC的特點(diǎn)，而且跨出了革命性的一步。而目前，新型的DCS與新型的PLC，都有向?qū)Ψ娇繑n的趨勢(shì)。新型的DCS已有很強(qiáng)的順序控制功能；而新型的PLC，在處理閉環(huán)控制方面也不差，并且兩者都能組成大型網(wǎng)絡(luò)，DCS與PLC的適用范圍，已有很大的交叉。下一節(jié)就僅以DCS與FCS進(jìn)行比較。在前面的章節(jié)中，實(shí)際上已涉及到DCS與FCS的差異，下面將就體系結(jié)構(gòu)、投資、設(shè)計(jì)、使用等方面進(jìn)行敘述。
