我們?cè)诟鞣N場(chǎng)合看到了繼電器連接的控制，那已經(jīng)是時(shí)代的過(guò)去，如今的繼電器只能作為低端的基層控制模塊或者簡(jiǎn)單的設(shè)備中使用到；而PLC的出現(xiàn)也成為了劃時(shí)代的主題，通過(guò)極其穩(wěn)定的硬件穿插靈活的軟件控制，使得自動(dòng)化走向了新的高潮。
PLC的大特點(diǎn)在于：電氣工程師已不再電氣的硬件上花費(fèi)太多的心計(jì)，只要將按鈕開(kāi)關(guān)或感應(yīng)器的輸入點(diǎn)連接到PLC的輸入點(diǎn)上就能解決問(wèn)題，通過(guò)輸出點(diǎn)連接接觸器或繼電器來(lái)控制大功率的啟動(dòng)設(shè)備，而小功率的輸出設(shè)備直接連接就可以。
PLC的內(nèi)部包含了具有中央處理器的，并帶有外部I/O口擴(kuò)展的I/O接口地址和存儲(chǔ)器三大塊組成，的核心是由一個(gè)或者多個(gè)累加器組成，它們具有邏輯的數(shù)學(xué)運(yùn)算能力，并能讀取程序存儲(chǔ)器的內(nèi)容通過(guò)計(jì)算后去驅(qū)動(dòng)相應(yīng)的存儲(chǔ)器和I/O接口；I/O口將內(nèi)部累加器和外部的輸入和輸出系統(tǒng)連接起來(lái)，并將相關(guān)的數(shù)據(jù)存入程序存儲(chǔ)器或者數(shù)據(jù)存儲(chǔ)器中；存儲(chǔ)器可以將I/O口輸入的數(shù)據(jù)存入存儲(chǔ)器中，并在工作時(shí)調(diào)轉(zhuǎn)到累加器和I/O接口上，存儲(chǔ)器分程序存儲(chǔ)器ROM和數(shù)據(jù)存儲(chǔ)器RAM，ROM可以將數(shù)據(jù)的存入存儲(chǔ)器中，而RAM只能作為計(jì)算時(shí)臨時(shí)計(jì)算使用的緩沖空間。
