enable to create or write a tdms file with labview 2014

[bmtanguay]

Hello,

I need some help. I'm new with LabView. I've been trying to create a TDMS file but it doesn't work. My code in the link below is really simple, but I don't know what the problem is.My code doesn't throw any errors so I don't know what to look for in the internet. Once my code is done excuting, no file is created. I use LabView 2014 and my laptoop has windows 7 on it.  My question is, is there any specific configurations I need to do everytime I create a new VI that will read/create/ write a .tdms so that my code can work correctly because writing in a .txt file works perfectly.

Thank you and sorry for my english

Hi bmtanguay,

do you want to run your VI on your cRIO9074?

Where do you think does your cRIO create that file? A cRIO is a computer of its own - and it has it's own "harddrive". This is where your file is created: C partion on your cRIO!

You cannot create a file on your Windows pc from within a VI running on your cRIO!

Gerd,

Where was a cRIO mentioned?

Hi RavensFan,

the AI0/AI1 shared variables in the VI were shown in the context help with a path like "cRIO9074…"…

Ok.  Thanks.  I see that now.  I didn't have context help open when looking at the VI.  And I didn't notice the FPGA symbol withing those shared variables.  Nothing at jumped out at me as being cRIO.
