PLC的應(yīng)用 
    目前，PLC在國(guó)內(nèi)外已廣泛應(yīng)用于鋼鐵、石油、化工、電力、建材、機(jī)械制造、汽車(chē)、輕紡、交通運(yùn)輸、環(huán)保及文化娛樂(lè)等各個(gè)行業(yè)，隨著其性能價(jià)格比的不斷提高，應(yīng)用的范圍還在不斷擴(kuò)大，PLC的應(yīng)用大致可歸納為以下幾類(lèi)。
    1)、開(kāi)關(guān)量的邏輯控制
    這是PLCzui基本、zui廣泛的應(yīng)用領(lǐng)域。PLC的邏輯控制取代傳統(tǒng)的繼電系統(tǒng)控制電路，實(shí)現(xiàn)邏輯控制、順序控制，既可用于單機(jī)控制，也可用于多機(jī)群控及自動(dòng)化生產(chǎn)線(xiàn)的控制等。如機(jī)床電氣控制、裝配生產(chǎn)線(xiàn)、電梯控制、冶金系統(tǒng)的高爐上料系統(tǒng)以及各種生產(chǎn)線(xiàn)的控制。    
    2)、運(yùn)動(dòng)控制
    PLC可以用于圓周運(yùn)動(dòng)或直線(xiàn)運(yùn)動(dòng)的控制。目前，大多數(shù)的PLC制造商都提供拖動(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，這一功能可廣泛用于各種機(jī)械，如金屬切削機(jī)床、金屬成型機(jī)床、機(jī)器人、電梯等。
    3)、過(guò)程控制
     過(guò)程控制是指對(duì)溫度、壓力、流量、速度等連續(xù)變化的模擬量的閉環(huán)控制。PLC采用相應(yīng)的A/D和D/A轉(zhuǎn)換模塊及各種各樣的控制算法程序來(lái)處理模擬量，完成閉環(huán)控制。PID調(diào)節(jié)是一般閉環(huán)控制系統(tǒng)中用得較多的一種調(diào)節(jié)方法。過(guò)程控制在冶金、化工、熱處理、鍋爐控制等場(chǎng)合有非常廣泛的應(yīng)用。現(xiàn)代的大、中型PLC一般都有閉環(huán)PID控制模塊，這一功能可以用PID子程序來(lái)實(shí)現(xiàn)，而更多的是使用PID模塊來(lái)實(shí)現(xiàn)。

  4)、數(shù)據(jù)處理
    PLC具有數(shù)學(xué)運(yùn)算（含矩陣運(yùn)算、函數(shù)運(yùn)算、邏輯運(yùn)算）、數(shù)據(jù)傳送、數(shù)據(jù)轉(zhuǎn)換、排序、查表、位操作等功能，可以完成數(shù)據(jù)的采集、分析及處理。這些數(shù)據(jù)可以通過(guò)通信接口傳送到的智能裝置進(jìn)行處理，或?qū)⑺鼈兇蛴溆谩?shù)據(jù)處理一般用于大型控制系統(tǒng)，如造紙、冶金、食品工業(yè)中的一些大型控制系統(tǒng)。
    5）、通信及聯(lián)網(wǎng)
    PLC通信括PLC相互之間、PLC與上位機(jī)、PLC與其它智能設(shè)備間的通信。PLC與其它智能控制設(shè)備一起，可以構(gòu)成“集中管理、分散控制"的分布式控制系統(tǒng)，滿(mǎn)足工廠自動(dòng)化系統(tǒng)發(fā)展的需要。
● PLC控制系統(tǒng)與繼電器控制系統(tǒng)的區(qū)別 ：
    ⑴ 組成器件不同：繼電器控制線(xiàn)路是許多真正的硬件繼電器組成，而梯形圖則由許多所謂“軟繼電器"組成。
    ⑵ 觸點(diǎn)數(shù)量不同：硬繼電器的觸點(diǎn)數(shù)量有限，用于控制的繼電器的觸 點(diǎn)數(shù)一般只有4～8對(duì)；而梯形圖中每個(gè)“軟繼電器"供編程使用的觸點(diǎn)數(shù)有無(wú)限對(duì)。
    ⑶ 實(shí)施控制的方法不同：在繼電器控制線(xiàn)路中，實(shí)現(xiàn)某種控制是通過(guò)各種繼電器之間硬接線(xiàn)解決的。而PLC控制是通過(guò)梯形圖即軟件編 程解決的。
    ⑷ 工作方式不同：在繼電器控制線(xiàn)路中，采用并行工作方式；而在梯形圖的控制線(xiàn)路中，采用串行工作方式。
