特點(diǎn)順序控制系統(tǒng)是指按照預(yù)定的受控執(zhí)行機(jī)構(gòu)動(dòng)作順序及相應(yīng)的轉(zhuǎn)步條件，一步一步進(jìn)行的自動(dòng)控制系統(tǒng)。其受控設(shè)備通常是動(dòng)作順序不變或相對(duì)固定的生產(chǎn)機(jī)械。這種控制系統(tǒng)的轉(zhuǎn)步主令信號(hào)大多數(shù)是行程開關(guān)（包括有觸點(diǎn)或無觸點(diǎn)行程開關(guān)、光電開關(guān)、干簧管開關(guān)、霍爾元件開關(guān)等位置檢測(cè)開關(guān)），有時(shí)也采用壓力繼電器、時(shí)間繼電器之類的信號(hào)轉(zhuǎn)換元件作為某些步的轉(zhuǎn)步主令信號(hào)。

????為了使順序控制系統(tǒng)工作可靠，通常采用步進(jìn)式順序控制電路結(jié)構(gòu)。所謂步進(jìn)式順序控制，是指控制系統(tǒng)的任一程序步（以下簡(jiǎn)稱步）的得電必須以前一步的得電并且本步的轉(zhuǎn)步主令信號(hào)已發(fā)出為條件。對(duì)生產(chǎn)機(jī)械而言，受控設(shè)備任一步的機(jī)械動(dòng)作是否執(zhí)行，取決于控制系統(tǒng)前一步是否已有輸出信號(hào)及其受控機(jī)械動(dòng)作是否已完成。若前一步的動(dòng)作未完成，則后一步的動(dòng)作無法執(zhí)行。這種控制系統(tǒng)的互鎖嚴(yán)密，即便轉(zhuǎn)步主令信號(hào)元件失靈或出現(xiàn)誤操作，亦不會(huì)導(dǎo)致動(dòng)作順序錯(cuò)亂。
