可編程邏輯控制器實(shí)質(zhì)是一種專用于工業(yè)控制的計(jì)算機(jī)，其硬件結(jié)構(gòu)基本上與微型計(jì)算機(jī)相同，基本構(gòu)成為：
一、電源
可編程邏輯控制器的電源在整個(gè)系統(tǒng)中起著十分重要的作用。如果沒(méi)有一個(gè)良好的、可靠的電源系統(tǒng)是無(wú)法正常工作的，因此，可編程邏輯控制器的制造商對(duì)電源的設(shè)計(jì)和制造也十分重視。一般交流電壓波動(dòng)在+10%(+15%)范圍內(nèi)，可以不采取其它措施而將PLC直接連接到交流電網(wǎng)上去
二、中央處理單元(CPU)
中央處理單元(CPU)是可編程邏輯控制器的控制中樞。它按照可編程邏輯控制器系統(tǒng)程序賦予的功能接收并存儲(chǔ)從編程器鍵入的用戶程序和數(shù)據(jù)；檢查電源、存儲(chǔ)器、I/O以及警戒定時(shí)器的狀態(tài)，并能診斷用戶程序中的語(yǔ)法錯(cuò)誤。當(dāng)可編程邏輯控制器投入運(yùn)行時(shí)，首先它以掃描的方式接收現(xiàn)場(chǎng)各輸入裝置的狀態(tài)和數(shù)據(jù)，并分別存入I/O映象區(qū)，然后從用戶程序存儲(chǔ)器中逐條讀取用戶程序，經(jīng)過(guò)命令解釋后按指令的規(guī)定執(zhí)行邏輯或算數(shù)運(yùn)算的結(jié)果送入I/O映象區(qū)或數(shù)據(jù)寄存器內(nèi)。等所有的用戶程序執(zhí)行完畢之后，*后將I/O映象區(qū)的各輸出狀態(tài)或輸出寄存器內(nèi)的數(shù)據(jù)傳送到相應(yīng)的輸出裝置，如此循環(huán)運(yùn)行，直到停止運(yùn)行。
為了進(jìn)一步提高可編程邏輯控制器的可靠性，對(duì)大型可編程邏輯控制器還采用雙CPU構(gòu)成冗余系統(tǒng)，或采用三CPU的表決式系統(tǒng)。這樣，即使某個(gè)CPU出現(xiàn)故障，整個(gè)系統(tǒng)仍能正常運(yùn)行。
三、存儲(chǔ)器
存放系統(tǒng)軟件的存儲(chǔ)器稱為系統(tǒng)程序存儲(chǔ)器。
存放應(yīng)用軟件的存儲(chǔ)器稱為用戶程序存儲(chǔ)器。
四、輸入輸出接口電路
1．現(xiàn)場(chǎng)輸入接口電路由光耦合電路和微機(jī)的輸入接口電路，作用是可編程邏輯控制器與現(xiàn)場(chǎng)控制的接口界面的輸入通道。
2．現(xiàn)場(chǎng)輸出接口電路由輸出數(shù)據(jù)寄存器、選通電路和中斷請(qǐng)求電路集成，作用可編程邏輯控制器通過(guò)現(xiàn)場(chǎng)輸出接口電路向現(xiàn)場(chǎng)的執(zhí)行部件輸出相應(yīng)的控制信號(hào)。
五、功能模塊
如計(jì)數(shù)、定位等功能模塊。
六、通信模塊

江陰張畏巖，積學(xué)工文，有聲藝林。甲午(公元1594年)，南京鄉(xiāng)試，寓一寺中，揭曉無(wú)名，大罵試官，以為瞇目。時(shí)有一道者，在傍微笑，張遽移怒道者。道者曰：「相公文必不佳。」

　　張怒曰：「汝不見(jiàn)我文，烏知不佳？」

　　道者曰：「聞作文，貴心氣和平，今聽(tīng)公罵詈，不平甚矣，文安得工？」

　　張不覺(jué)屈服，因就而請(qǐng)教焉。

　　道者曰：「中全要命；命不該中，文雖工，無(wú)益也。須自己做個(gè)轉(zhuǎn)變。」

　　張?jiān)唬骸讣仁敲绾无D(zhuǎn)變？」

　　道者曰：「造命者天，立命者我；力行善事，廣積陰德，何福不可求哉？」

　　張?jiān)唬骸肝邑毷浚文転椋俊?/p>

　　道者曰：「善事陰功，皆由心造，常存此心，功德無(wú)量，且如謙虛一節(jié)，并不費(fèi)錢，你如何不自反而罵試官乎？」

　　張由此折節(jié)自持，善日加修，德日加厚。丁酉(公元1597年)，夢(mèng)至一高房，得試錄一冊(cè)，中多缺行。問(wèn)旁人， 曰：「此今科試錄。」

　　問(wèn)：「何多缺名？」

　　曰：「科第陰間三年一考較，須積德無(wú)咎者，方有名。如前所缺，皆系舊該中式，因新有薄行而去之者也。」
