产品描述

在可编程逻辑控制器出现之前，一般要使用成百上千的继电器以及计数器才能组成具有相同功能的自动化系统，而现在，经过编程的简单的可编程逻辑控制模块基本上已经代潜了这些大型装置，可编程逻辑控制器的系统程序一般在出厂前已经初始化完毕，用户可以根据自己的需要自行编辑相应的用户程序来满足不同的自动化生产要求

初的可编程逻辑控制器只有电路逻辑控制的功能，所以被命名为可编程逻控制器，后来随着不断的发展，这些当初功能简单的计算机模块已经有了包括逻辑控制，时序控制、模拟控制、多机通信等许多的功能，名称也改为可编程控制器(Programmable Controler) ，但是由于它的简写也是PC与个人电脑(Personal Computer) 的简写冲突，也由于多年来的使用习惯，人们还是经常使用可编程逻辑控制器这一称呼，并在术语中沿用PLC这一缩写。

Product description

Before the programmable logic controller appeared, it was generally necessary to use hundreds of relays and counters to form an automation system with the same function, and now, simple programmable logic control modules have basically replaced these large devices, and the system program of programmable logic controller is generally initialized before the factory. Users can edit corresponding user programs according to their own needs to meet different automated production requirements

The initial programmable logic controller only has the function of circuit logic control, so it is named programmable logic controller. Later, with the continuous development, these initially simple computer modules have many functions, including logic control, timing control, analog control, multi-machine communication and so on. The name was also changed to Programmable Controler, but because its abbreviation was also a conflict between PC and Personal Computer, and because of its use over the years, the term programmable logic controller was often used. The abbreviation PLC is used in the term.
