您好,2470是USB链接的。
这个问题目前还是未解决,但搜到一个可能的方向,原文如下:
This error can result from not closing VISA references before exiting the VI. Even if you do not explicitly open a VISA reference, one is created whenever a read or write is performed. To avoid this error perform the following steps: Explicitly open all VISA references in your VI. Explicitly close all VISA references in your VI. Avoid halting execution with the abort button, because this will leave all the references open. If the steps above didn't solve the issue, you can also reset the NI MAX database following the article How to Fix or Reset the NI Measurement and Automation Explorer Database File. Alternatively, you can try reinstalling the Windows USB drivers.
我下一步打算按照这个思路试试,有结果的话会在这里说明。
感谢您的回复,如果您有其他解决办法,也请回复给我噢
