save to different files

[Valls]

This is a pretty straight forward question. I'm trying to save data to a lvm. file. The attached VI saves random generated values every time I turn on the boolean onto the desktop. However I have to stop and re-start the VI again in order to generate a new file. How could I generate a new file every time I turn on the boolean without stopping the VI?

Thanks in advance

Straightforward question, straightforward answer: change the filename. Your Express VI is configured to use the same name all the time, so what did you expect? Wire a value to the "File Name" input that has a value based on some other condition, like time, or phase of the moon, or whatever.

If a file already exists, you can select among the following options:

• Rename the existing file
• Append a sequential number to the filename
• Overwrite the file
• Append the data to the existing file
