PLC的主要模塊構(gòu)成（系統(tǒng)組成圖）

PLC主要由CPU模塊、輸入模塊、輸出模塊和編程器組成(見圖1），有的PLC還可以配備特殊功能模塊，用來完成某些特殊的任務(wù)。

  1．CPU模塊 

  CPU模塊主要由微處理器(CPU芯片)和存儲器組成。在PLC控制系統(tǒng)中廠CPU模塊相當(dāng)于人的大腦，它不斷地采集輸入信號，執(zhí)行用戶程序，刷新系統(tǒng)的輸出；存儲器用來儲存程序和數(shù)據(jù)。

  2.I/O模塊 

  輸入(1nput)模塊和輸出(Output)模塊簡稱為I／O模塊，它們是系統(tǒng)的眼、耳、手、腳，是聯(lián)系外部現(xiàn)場設(shè)備和CPU模塊的橋梁。   

輸入模塊用來接收和采集輸入信號，開關(guān)量輸入模塊用來接收從按鈕；選擇開關(guān)、數(shù)字撥碼開關(guān)、限位開關(guān)、接近開關(guān)、光電開關(guān)、壓力繼電器等過來的開關(guān)量輸入信號；模擬量輸入模塊用來接收電位器、測速發(fā)電機和各種變送器提供的連續(xù)變化的模擬量電流、電壓信號。

    開關(guān)量輸出模塊用來控制接觸器、電磁閥、電磁鐵、指示燈、數(shù)字顯示裝置和報警裝置等輸出設(shè)備，模擬量輸出模塊月手來控制調(diào)節(jié)閥、變頻器等執(zhí)行裝置。   

圖1 PLC控制系統(tǒng)示意圖 

  CPU模塊的工作電壓一般是5V，而PLC的輸入／輸出信號電壓一般較高，如直流24V和交流220V。從外部引入的尖峰電壓和干擾噪聲可能損壞CPU模塊中的元器件，或使PLC不能正常工作。在I／O模塊中，用光耦合器、光電晶閘管、小型繼電器等器件來隔離PLC的內(nèi)部電路和外部的I／O電路，I／O模塊除了傳遞信號外，還有電平轉(zhuǎn)換與隔離的作用。

  3．編程器   

    編程器用來生成用戶程序，并用它進(jìn)行編輯、檢查、修改和監(jiān)視用戶程序的執(zhí)行情況。手持式編程器不能直接輸入和編輯梯形圖，只能輸入和編輯指令表程序，因此又叫做指令編程器。它的體積小，價格便宜，一般用來給小型PLC編程，或者用于現(xiàn)場調(diào)試和維護(hù)。

    使用編程軟件可以在計算機的屏幕上直接生成和編輯梯形圖、指令表、功能塊圖和順序功能圖程序，并可以實現(xiàn)不同編程語言的相互轉(zhuǎn)換。程序被編譯后下載到PLC，也可以將PLC中的程序上傳到計算機。程序可以存盤或打印，通過網(wǎng)絡(luò)，還可以實現(xiàn)遠(yuǎn)程編程和傳送。

    4．電源   

    PLC一般使用220V交流電源或24V直流電源。內(nèi)部的開關(guān)電源為各模塊提供DC 5V，±12V，24V等直流電源。小型PLC一般都可以為輸入電路和外部的電子傳感器(如接近開關(guān))提供24V直流電源，驅(qū)動PLC負(fù)載的直流電源一般由用戶提供。
