摘要
首先分析了卷幅式广告机的实用价值及工作原理，其次根据实际情况分析了广告机的控制要求及特点，最后介绍了利用ACMY-S80型可编程控制器实现可变画面的控制，给出了PLC的I／O分配及控制梯形图，并对该梯形图所实现的控制逻辑及执行过程进行了详细分析。
Firstly, the principle and value in practice are analyzed. Secondly, the control and characteristics of the rolling advertising machine are analyzed according to the demand of real case. Finally, the control of the changing pictures is actualized by using ofACMY-S80. I/O distribution and controlling LAD of PLC are also given in this paper. And the control logic and executive process, which are realized by LAD, are detailedly analyzed.
