基于PLC的LED数码显示控制设计 摘要 本文首先介绍 了可编程控制器（PLC）的历史和发展，以及对PLC的执行过程进行 了研究讨论。接着对可编程控制器的各种配置进行了物理描述、对各组成部分的功能进 行了概述。然后又介绍了LED的种类、工作原理以及优点。紧接着对三菱的可编程控制 程序软件GX Devevloper进行了介绍，最后对梯形图、I∕O分配表进行了简单的介绍。 PLC LED 可编程控制器 三菱 关键词： Abstract his paper first introduced the programmable controller (PLC )and the history of development, as well as on the PLC implementation process are discussed. Then on the programmable controller of various configurations were physical description, on the function of each part are summarized. Then introduced the LED type, working principle and advantages. Followed by Mitsubishi programmable control software GXDevevloper are introduced, finally the ladder diagram, I/ Oallocation table were introduced Key words: PLC LED PLC Mitsubishi
