不同型號的PLC，其內部結構和功能不盡相同，但其主體結構形式大體相同。
    （1）PLC的硬件組成。PLC是由中央處理器（CPU）、存儲器、輸入/ 輸出（I / O）模塊、編程器、電源和外部設備組成。PLC的硬件設備是通用的，便于用戶按需要組合。PLC的各部分都采用總線結構。
    1）中央處理器（CPU）。PLC常用的中央處理器為通用微處理器、單片機芯片、位片式微處理器等。它的主要作用是由微處理器通過數據總線、地址線、控制總線以及輔助電路連接存儲器、接口及I / O模塊，診斷和監控PLC的硬件狀態；同時，借助編程器接收鍵入的用戶程序和數據、讀取、解釋并執行用戶程序；按規定的時序接收輸入狀態、更新輸出狀態，與外部設備交換信息等。總之，由CPU實現對整個PLC的控制和管理。
    2）存儲器。在PLC中存儲器用來存放系統程序、用戶程序和工作數據。
    系統程序是由控制器的制造廠家在研制系統時確定的程序，它包括監控程序、解釋程序、故障自診斷程序、模塊化應用功能子程序極其他各種管理程序等。系統程序一干二凈都固化在只讀存儲器（ROM）或EPROM存儲器中，用戶不能訪問、修改這一部分存儲器的內容。
    用戶程序是隨PLC的使用環境而定的，隨生產工藝的不同而變動，但是變化并不是經常發生。用戶根據實際控制的需要，用PLC的編程語言編制應用程序，通過編程器輸入到PLC的用戶存儲器（區）。為了便于程序的調試、修改、擴充和完善，該存儲器使用隨機存取存儲器（RAM）。
    3）輸入/輸出（I/O）模塊。I/O模塊是CPU與工業現場I/O裝置或其他外部設備的連接部件。它將現場信號轉換成PLC內部的信號電平，或使PLC內部信號電平與外部執行元件相匹配。常用PLC的I/O接口分開關量（包括數字量）和模擬量兩類，每一類又區分為輸入接口和輸出接口。
    與微機的I/O接口工作于弱電的情況不同，PLC的I/O接口是按強電要求設計的，即其輸入接口可以接收強電信號，其輸出接口可以直接和強電設備相連接。
    4）電源。PLC的電源單元負責將外部提供的交流店轉換為PLC內部所需要的直流電源，有的PLC還可以為輸入電路和少量的外部電平簡稱裝置提供24V直流電源。PLC中還有備用電池（一般為鋰電池），用于掉電情況下保存程序和數據。
    5）編程器。PLC的編程器是用來開發、調試、運行應用程序的特殊工具，一般由鍵盤、顯示屏、智能處理器、外部設備等組成，通過通信接口與PLC連接。
    編程器主要功能：作為編程和開發應用程序的工具；與PLC進行人機對話的媒介；介入PLC和過程供職的手段。PLC的各制造廠家都為自己的PLC系列產品培植編程器，而且本系列PLC的編程器是兼容的。
    6）擴展接口。擴展接口是為PLC中心單元與擴展單元或擴展單元之間的連接用的，以擴展PLC的規模。
    （2）PLC的的軟件組成。PLC的基本軟件包括系統軟件和用戶應用軟件。系統軟件決定PLC的功能。PLC的硬件通過基本軟件實現對被控制對象的控制。
    系統軟件一般包括操作系統、語言編譯系統、各種功能軟件等。
    用戶應用軟件大多采用梯形圖（Ladder）語言，其次為語句表（Statement Language）。梯形圖與繼電器控制線路圖相似，因此，對熟悉繼電器控制的人員就起到了易學、易懂和便于使用的效果。
