開環(huán)控制
開關量的開環(huán)控制是PLC的最基本控制功能。PLC的指令系統(tǒng)具有強大的
邏輯運算能力，很容易實現(xiàn)定時、計數(shù)、順序(步進)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)
對于模擬量的閉環(huán)控制系統(tǒng)，除了要有開關量的輸入輸出外，還要有模擬量的輸入輸出點，以便采樣輸入和調節(jié)輸出實現(xiàn)對溫度、
流量、壓力、位移、速度等參數(shù)的連續(xù)調節(jié)與控制。目前的PLC不但大型、中型機具有這種功能外，還有些小型機也具有這種功能。
[9]
數(shù)字量控制
控制系統(tǒng)具有旋轉編碼器和脈沖伺服裝置(如
步進電動機)時，可利用PLC實現(xiàn)接收和輸出高速脈沖的功能，實現(xiàn)數(shù)字量控制，較為先進的PLC還專門開發(fā)了數(shù)字控制模塊，可實現(xiàn)曲線插補功能，近來又推出了新型運動單元模塊，還能提供數(shù)字量控制技術的編程語言，使PLC實現(xiàn)數(shù)字量控制更加簡單。
[9]
數(shù)據(jù)采集監(jiān)控
由于PLC主要用于現(xiàn)場控制，所以采集現(xiàn)場數(shù)據(jù)是十分必要的功能，在此基礎上將PLC與上位計算機或觸摸屏相連接，既可以觀察這些數(shù)據(jù)的當前值，又能及時進行統(tǒng)計分析，有的PLC具有數(shù)據(jù)記錄單元，可以用一般個人電腦的存儲卡插入到該單元中保存采集到的數(shù)據(jù)。PLC的另一個特點是自檢信號多．利用這個特點，PLC控制系統(tǒng)可以實現(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。
