准备材料：

硬件： 电脑、大屏幕

软件：组态王6.5 step7 v4.0  虚拟串口软件Virtual_Serial_Port_Driver_Ver7.2 pj.rar 

北京华晟云联IASIMU107B.exe 

灯光效果：随着音乐，组态王中设置的灯按照要求亮起

 实施过程:

1.按照流程图在step7中，编制程序完成并导出文件。*.awl文件。

2.在组态王中按图给定放置画出图形界面、连接变量。

3.打开虚拟串口软件、设置虚拟串口。

4..打开IASIMU107B.exe 仿真程序打开*.awl文件。同时在设置串口处，将串口配对。

 5、运行组态王、运行仿真plc、将虚拟plc打到run,

组态王和仿真程序建立通信，可以看到灯光效果。
