1、《可编程控制器原理及应用》实验指导书８５杭州电子工业学院自动化分院2000年11月前言可编程控制器是采用微机技术的通用工业自动化装置，近几年来，在国内得到迅速推广普及。正改变着工厂自动控制的面貌，对传统的技术改造、发展新型工业具有重大的实际意义。本实验指导书旨在帮助学生通过实验更好的掌握PLC的结构特点、工作原理和编程方法，从而为今后在工程上的应用打下坚实的基础。全书分为三个部分：第一部分是以三菱可编程序控制器配THPLC-A型教学实验设备为实验对象；第二部分是以三菱可编程控制器配SAC-PC教学实验设备为实验对象；第三部分则是实验参考。在实验前学生应根

2、据选定的实验设备参考相应的指导书内容进行预习，实验过程中应严格按照实验要求操作，注意安全，实验后书写实验报告。８５目录第一部分三菱可编程序控制器配THPLC-A型教学实验设备实验一可编程控制器的基本指令编程练习········································3实验二装配流水线控制的模拟····························································6实验三三相异步电动机的星/三角形换接启动控制···························8实验四LED数码显示
