可編程控制器的組成介紹（以FX2N系列PLC為例）
外部的開關信號、模擬信號以及各種傳感器檢測信號作為PLC的輸入變量，它們經PLC的輸入端子進入PLC的輸入存儲器，收集和暫存被控對象實際運行的狀態信息和數據；經PLC內部運算與處理后，按被控對象實際動作要求產生輸出結果；輸出結果送到輸出端子作為輸出變量，驅動執行機構。PLC的各部分協調一致地實現對現場設備的控制。
（1）中央處理器CPU
CPU的主要作用是解釋并執行用戶及系統程序，通過運行用戶及系統程序完成所有控制、處理、通信以及所賦予的其它功能，控制整個系統協調一致地工作。常用的CPU主要有通用微處理器、單片機和雙極型位片機。
（2）存儲器模塊
隨機存取存儲器RAM用于存儲PLC內部的輸入、輸出信息，并存儲內部繼電器（軟繼電器）、移位寄存器、數據寄存器、定時器／計數器以及累加器等的工作狀態，還可存儲用戶正在調試和修改的程序以及各種暫存的數據、中間變量等。
只讀存儲器ROM用于存儲系統程序。可擦除可編程序的只讀存儲器EPROM主要用來存放PLC的操作系統和監控程序，如果用戶程序已完全調試好，也可將程序固化在EPROM中。
