開環(huán)控制
開關(guān)量的開環(huán)控制是PLC的最基本控制功能。PLC的指令系統(tǒng)具有強(qiáng)大的
邏輯運(yùn)算能力，很容易實(shí)現(xiàn)定時(shí)、計(jì)數(shù)、順序(步進(jìn))等各種邏輯控制方式。大部分PLC就是用來取代傳統(tǒng)的繼電接觸器控制系統(tǒng)。

模擬量閉環(huán)
對(duì)于模擬量的閉環(huán)控制系統(tǒng)，除了要有開關(guān)量的輸入輸出外，還要有模擬量的輸入輸出點(diǎn)，以便采樣輸入和調(diào)節(jié)輸出實(shí)現(xiàn)對(duì)溫度、
流量、壓力、位移、速度等參數(shù)的連續(xù)調(diào)節(jié)與控制。目前的PLC不但大型、中型機(jī)具有這種功能外，還有些小型機(jī)也具有這種功能。
[9]
數(shù)字量控制
控制系統(tǒng)具有旋轉(zhuǎn)編碼器和脈沖伺服裝置(如
步進(jìn)電動(dòng)機(jī))時(shí)，可利用PLC實(shí)現(xiàn)接收和輸出高速脈沖的功能，實(shí)現(xiàn)數(shù)字量控制，較為先進(jìn)的PLC還專門開發(fā)了數(shù)字控制模塊，可實(shí)現(xiàn)曲線插補(bǔ)功能，近來又推出了新型運(yùn)動(dòng)單元模塊，還能提供數(shù)字量控制技術(shù)的編程語言，使PLC實(shí)現(xiàn)數(shù)字量控制更加簡(jiǎn)單。
[9]
數(shù)據(jù)采集監(jiān)控
由于PLC主要用于現(xiàn)場(chǎng)控制，所以采集現(xiàn)場(chǎng)數(shù)據(jù)是十分必要的功能，在此基礎(chǔ)上將PLC與上位計(jì)算機(jī)或觸摸屏相連接，既可以觀察這些數(shù)據(jù)的當(dāng)前值，又能及時(shí)進(jìn)行統(tǒng)計(jì)分析，有的PLC具有數(shù)據(jù)記錄單元，可以用一般個(gè)人電腦的存儲(chǔ)卡插入到該單元中保存采集到的數(shù)據(jù)。PLC的另一個(gè)特點(diǎn)是自檢信號(hào)多．利用這個(gè)特點(diǎn)，PLC控制系統(tǒng)可以實(shí)現(xiàn)白診斷式監(jiān)控，減少系統(tǒng)的故障，提高系統(tǒng)的可靠性。
