labview支持USB通信吗？

用笔记本运行labview与PLC通信
笔记本没有串口
于是用了个USB转串口的转换口
现在是的问题是labview支持USB通信吗？
用VISA可以吗？
谢谢

usb转串的话应该跟串一样用

就是说装了USB转串口的驱动后，原来在台式机上运行的labview程序就可以原样不动的用了
是吗？
谢谢

应该差不多，串口设对。

labview中只显示了com3，据说是什么虚拟com口，就是专门为USB转com口设的
不知道我说的对不对

那就对了

I believe you are right. I am using a USB-RS232 convertor from Radio Shack. After installing the driver for the convertor, the Device Manager in Windows can identify the convertor and assign a new com port for it, whatever the port number is, say COM4. Then you can use this port, COM4, transparently in LabVIEW using the same VISA functions.

thanks a lot !!!
i can't find a driver programme
so i bought a (底坐)for my portable PC
it is ok for running labview
so i also believe your are right !!!
