摘要

PLC可編程序控制器：PLC英文全稱Programmable Logic Controller ,中文全稱為可編程邏輯控制器，定義是:一種數字運算操作的電子系統，專為在工業環境應用而設計的。PLC是基于電子計算機，且適用于工業現場工作的電控制器。它源于繼電控制裝置，但它不像繼電裝置那樣，通過電路的物理過程實現控制，而主要靠運行存儲于PLC內存中的程序，進行入出信息變換實現控制。它采用一類可編程的存儲器，用于其內部存儲程序，執行邏輯運算,順序控制，定時，計數與算術操作等面向用戶的指令，并通過數字或模擬式輸入/輸出控制各種類型的機械或生產過程. [1]

Abstract

PLC programmable logic controller: PLC Programmable Logic Controller English name, Chinese called the programmable logic controller, the definition is: the operation of a digital electronic computing systems for environmental applications in the industrial design. PLC is based on electronic computers, and apply to the industrial scene, the work of the controller. It originated from relay control devices, but it does not relay device, through circuit to achieve control of the physical processes, and mainly rely on running in the memory stored in the PLC process, transform information into and out of control. It uses a programmable memory for its internal storage procedures, the implementation of logical, sequential control, timing, counting and arithmetic operations such as user-oriented instructions, and through digital or analog input / output control of all types mechanical or production process.

Key words: programmable logic controller (PLC); industrial washing machine; Contro
