CPU是PLC的核心，起神經中樞的作用，每套PLC至少有一個CPU，它按PLC的係統程序賦予的功能接收並存貯用戶程序和數據，用掃描的方式採集由現場輸入裝置送來的狀態或數據，並存入規定的寄存器中，同時，診斷電源和PLC內部電路的工作狀態和編程過程中的語法錯誤等。進入運行後，從用戶程序存貯器中逐條讀取指令，經分析後再按指令規定的任務產生相應的控制信號，去指揮有關的控制電路。 CPU主要由運算器、控制器、寄存器及實現它們之間聯係的數據、控制及狀態總線構成，CPU單元還包括外圍芯片、總線接口及有關電路。內存主要用於存儲程序及數據，是PLC不可缺少的組成單元。 在使用者看來，不必要詳細分析CPU的內部電路，但對各部分的工作機制還是應有足夠的理解。CPU的控制器控制CPU工作，由它讀取指令、解釋指令及執行指令。但工作節奏由震蕩信號控制。運算器用於進行數字或邏輯運算，在控制器指揮下工作。寄存器參與運算，並存儲運算的中間結果，它也是在控制器指揮下工作。CPU速度和內存容量是PLC的重要參數，它們決定著PLC的工作速度，IO數量及軟件容量等，因此限制著控制規模。KVP 1701T19LO CHAIN KNUCKLE ACETAL PLASTIC 20FT LENGTH CONVEYOR BELT D397446
