1．*處理單元（CPU）
CPU作為整個(gè)PLC的核心，起著總指揮的作用。CPU一般由控制電路、運(yùn)算器和寄存器組成。這些電路通常都被封裝在一個(gè)集成電路的芯片上。CPU通過(guò)地址總線、數(shù)據(jù)總線、控制總線與存儲(chǔ)單元、輸入輸出接口電路連接。CPU的功能有以下一些：從存儲(chǔ)器中讀取指令，執(zhí)行指令，取下一條指令，處理中斷。
2．存儲(chǔ)器（RAM、ROM）
存儲(chǔ)器主要用于存放系統(tǒng)程序、用戶程序及工作數(shù)據(jù)。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；存放工作數(shù)據(jù)的存儲(chǔ)器稱為數(shù)據(jù)存儲(chǔ)器。常用的存儲(chǔ)器有RAM、EPROM和EEPROM。RAM是一種可進(jìn)行讀寫(xiě)操作的隨機(jī)存儲(chǔ)器存放用戶程序，生成用戶數(shù)據(jù)區(qū)，存放在RAM中的用戶程序可方便地修改。RAM存儲(chǔ)器是一種高密度、低功耗、價(jià)格便宜的半導(dǎo)體存儲(chǔ)器，可用鋰電池做備用電源。掉電時(shí)，可有效地保持存儲(chǔ)的信息。EPROM、EEPROM都是只讀存儲(chǔ)器。用這些類(lèi)型存儲(chǔ)器固化系統(tǒng)管理程序和應(yīng)用程序。
3．輸入輸出單元（I/O單元）
I/O單元實(shí)際上是PLC與被控對(duì)象間傳遞輸入輸出信號(hào)的接口部件。I/O單元有良好的電隔離和濾波作用。接到PLC輸入接口的輸入器件是各種開(kāi)關(guān)、按鈕、傳感器等。PLC的各輸出控制器件往往是電磁閥、接觸器、繼電器，而繼電器有交流和直流型，高電壓型和低電壓型，電壓型和電流型。
4．電源
PLC電源單元包括系統(tǒng)的電源及備用電池，電源單元的作用是把外部電源轉(zhuǎn)換成內(nèi)部工作電壓。PLC內(nèi)有一個(gè)穩(wěn)壓電源用于對(duì)PLC的CPU單元和I/O單元供電。
5．編程器
編程器是PLC的zui重要外圍設(shè)備。利用編程器將用戶程序送入PLC的存儲(chǔ)器，還可以用編程器檢查程序，修改程序，監(jiān)視PLC的工作狀態(tài)。除此以外，在個(gè)人計(jì)算機(jī)上添加適當(dāng)?shù)挠布涌诤蛙浖纯捎脗€(gè)人計(jì)算機(jī)對(duì)PLC編程。利用微機(jī)作為編程器，可以直接編制并顯示梯形圖。
