"Save measurement to file"-VI doesn't obey the "Use next avaible file name" setting

[ReBoot]

I'm using this express VI to store data. In it's properties, there's the "If a file already exists: Use next avaible file name" radio box which does not work. Instead, it appends everything to the one file it created on the first run. My VI has a while-loop with an embedded flat sequence with the writing-VI being in the last frame of the flat sequence. LV 8.5, Linux

Hi There.

Could You make a screendump of Your VI?

I tried using the Express VI on both LV7 Express (Base,Win), and LV8.5 (Base, Win) , and it works perfectly....

[ReBoot]

I've attached my VI. Currently, the save-VI gets it's file name from some other VIs, but I do that because it doesn't work otherwise. When I clear the "Filename"-input, it starts appending.

Hi ReBoot

I think i've found the Source of Error......When You generate the filepath You use a Concatenate strings with a Constant stating "Files/file" the problem her is the "/". It might be that it should be a Backslash "\"......

Try it....

Best Regards BCL

No no, everything's fine as it is. The problem starts when I remove the Filename-input from the Save-VI. Then the Save-VI refuses to take the next avaible file name. However, I'd like to be able to remove all this filename-code and let the Save-VI handle all the file naming.

Hi ReBoot,

how should you filenames look like?

That doesn't matter as long as they're indexed.

Hi Again.

Unfortunately i cannot run You Vi, because of missing Hardware, But if i Copy the Express VI to a new VI, and run it, it generates a new file everytime.

Try running the attached example.......Do You see the same behavior?

Hi ReBoot,

why do you change everytime the filename? if you connect everytime the same name it should work.

It does not work because the problem I mentioned in the OP occurs.

Will try the uploaded VI!
