摘要
利用顺序功能图和梯形图来编制用户程序,以实现单台设备或生产过程的顺序控制,是PLC的主要功能之一。以液压回转工作台的顺序控制为例,论述了三菱FX2N系列PLC的用户程序设计方法;通过比较,指出了各种方法的应用特点。
One of main functions of PLC is realization of the sequential control on single device or production process by means of the sequential function chart and the ladder diagram to organize user's control program. Taking the hydraulic rotating table as example, the design methods of sequential control program using FX2N PLC from Mitsubishi, the application features of every method by comparison were presented.
