浅谈S7-200 smart PLC实现一键启停编程的六种方法

The Six Ways of Realizing One-Click Start-stop Programming of S7-200 Smart PLC

随着科学技术的发展,PLC在工农业等各个领域得到了广泛的应用;往往在实际的工程应用中会有输入端子不够用的情况,而我们又不想增加I/O模块,所以在控制设备启停的时候我们可以使用一个按键来控制设备的启动与停止,以节约PLC的输入端子。

With the development of science and technology,PLC has been widely used in various fields such as industry and agriculture.There are cases where input terminals are not enough in practical engineering applications,and people do not want to increase I/O modules.Therefore,to save the input terminals of the PLC,people can use a button to control the start and stop of the device when the control device starts and stops.
