 目前，在國(guó)內(nèi)外PLC已廣泛應(yīng)用冶金、石油、化工、建材、機(jī)械制造、電力、汽車、輕工、環(huán)保及文化等各行各業(yè)，隨著PLC性能價(jià)格比的不斷提高，其應(yīng)用領(lǐng)域不斷擴(kuò)大。從應(yīng)用類型看，PLC的應(yīng)用大致可歸納為以下幾個(gè)方面：

1.開關(guān)量邏輯控制

利用PLCzui基本的邏輯運(yùn)算、定時(shí)、計(jì)數(shù)等功能實(shí)現(xiàn)邏輯控制，可以取代傳統(tǒng)的繼電器控制，用于單機(jī)控制、多機(jī)群控制、生產(chǎn)自動(dòng)線控制等，例如：機(jī)床、注塑機(jī)、印刷機(jī)械、裝配生產(chǎn)線、電鍍流水線及電梯的控制等。這是PLCzui基本的應(yīng)用，也是PLCzui廣泛的應(yīng)用領(lǐng)域。

2.運(yùn)動(dòng)控制

大多數(shù)PLC都有拖動(dòng)步進(jìn)電機(jī)或伺服電機(jī)的單軸或多軸位置控制模塊。這一功能廣泛用于各種機(jī)械設(shè)備，如對(duì)各種機(jī)床、裝配機(jī)械、機(jī)器人等進(jìn)行運(yùn)動(dòng)控制。

3.過程控制

大、中型PLC都具有多路模擬量I/O模塊和PID控制功能，有的小型PLC也具有模擬量輸入輸出。所以PLC可實(shí)現(xiàn)模擬量控制，而且具有PID控制功能的PLC可構(gòu)成閉環(huán)控制，用于過程控制。這一功能已廣泛用于鍋爐、反應(yīng)堆、水處理、釀酒以及閉環(huán)位置控制和速度控制等方面。

   4.數(shù)據(jù)處理

 現(xiàn)代的PLC都具有數(shù)學(xué)運(yùn)算、數(shù)據(jù)傳送、轉(zhuǎn)換、排序和查表等功能，可進(jìn)行數(shù)據(jù)的采集、分析和處理，同時(shí)可通過通信接口將這些數(shù)據(jù)傳送給其它智能裝置，如計(jì)算機(jī)數(shù)值控制（CNC）設(shè)備，進(jìn)行處理。

 5.通信聯(lián)網(wǎng)

 PLC的通信包括PLC與PLC、PLC與上位計(jì)算機(jī)、PLC與其它智能設(shè)備之間的通信，PLC系統(tǒng)與通用計(jì)算機(jī)可直接或通過通信處理單元、通信轉(zhuǎn)換單元相連構(gòu)成網(wǎng)絡(luò)，以實(shí)現(xiàn)信息的交換，并可構(gòu)成“集中管理、分散控制”的多級(jí)分布式控制系統(tǒng)，滿足工廠自動(dòng)化（FA）系統(tǒng)發(fā)展的需要。
