電子技術(shù)發(fā)展起來(lái)了，單板機(jī)出現(xiàn)了，后來(lái)人們嘗試使用單板機(jī)來(lái)替代繼電器電路，結(jié)果很復(fù)雜的邏輯，只要集成在一塊板子上就可以滿足功能要求了。所以工業(yè)電氣系統(tǒng)能實(shí)現(xiàn)更復(fù)雜的邏輯控制，體積又小，維護(hù)起來(lái)比繼電器容易多了。但是單板機(jī)可靠性不行，工業(yè)場(chǎng)所需要抗干擾很強(qiáng)，粉塵和震動(dòng)也很厲害，而且使用匯編語(yǔ)言編程，一般電工都學(xué)不會(huì)。單片機(jī)出來(lái)以后，單板機(jī)的功能基本上集成到一塊芯片上，所以有家叫莫迪康的公司設(shè)計(jì)了PLC這款產(chǎn)品出來(lái)了，硬件考慮了工業(yè)場(chǎng)所要求，處理比較穩(wěn)定可靠，然后軟件根據(jù)電工的思維習(xí)慣，弄出了一套梯形圖編程的系統(tǒng)來(lái)，和線下的繼電器電路差不多，這樣通過(guò)電腦上“接線”，用符合來(lái)替代實(shí)物，就可以實(shí)現(xiàn)“軟”方法來(lái)修改邏輯電路了。
