摘要
PLC可编程序控制器：PLC英文全称Programmable Logic Controller ,中文全称为可编程逻辑控制器，定义是:一种数字运算操作的电子系统，专为在工业环境应用而设计的。PLC是基于电子计算机，且适用于工业现场工作的电控制器。它源于继电控制装置，但它不像继电装置那样，通过电路的物理过程实现控制，而主要靠运行存储于PLC内存中的程序，进行入出信息变换实现控制。它采用一类可编程的存储器，用于其内部存储程序，执行逻辑运算,顺序控制，定时，计数与算术操作等面向用户的指令，并通过数字或模拟式输入/输出控制各种类型的机械或生产过程.

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
