描述

PLC一般用在小型自控場(chǎng)所，比如設(shè)備的控制或少量的模擬量的控制及連鎖，而大型的應(yīng)用一般都是DCS。當(dāng)然，這個(gè)概念不準(zhǔn)確，但很直觀，習(xí)慣上我們把大于600點(diǎn)的系統(tǒng)成為DCS，小于這個(gè)規(guī)模叫做PLC。說(shuō)了這么多PLC與DCS的區(qū)別，但我們應(yīng)該認(rèn)識(shí)到，PLC與DCS發(fā)展到今天，事實(shí)上都在向彼此靠攏，嚴(yán)格的說(shuō)，現(xiàn)在的PLC與DCS已經(jīng)不能一刀切開，很多時(shí)候之間的概念已經(jīng)模糊了?，F(xiàn)在，我們來(lái)討論一下彼此的相同（似）之處。
