Accessing CRIO files from LabVIEW

Technical NI LabVIEW
1

I am exploring the ability to read robot operating parameters at program startup. This would allow me to make quick changes to tuning parameters without having to redeploy code. I have successfully used the read and write ini vi’s to my computer as a test. I am now trying to read and write to the CRIO memory. Using ftp, I see a folder labeled ‘ni-rt/LabVIEW Data’ on the CRIO. This is where I would like to read/write to.

My problem is the syntax for the file path. I keep getting an error about I must use an absolute path and not a relative path. Has anyone successfully done this and what is the syntax?

I have attached my current vi attempt for reference.

Thanks

We store our files on the root of the cRIO. We use a absolute path c:\filename.ext

We actually have an example that may help. It is installed on your machine at:
\Program Files\National Instruments\LabVIEW 2011\examples\FRC\File\Load and Save Preferences\Load and Save Preferences.lvproj

Sorry this didn’t make it into the Example Finder - it was written too late for that.
