Real time 8.6 and tdms

[JChec]

Hi all,

Using a CRIO 9012 with Labview 8.6 and labview real time 8.6 and now that TDMS is supported and I'm wanting to use it on my cRIO. Having a problem though... tdms files besides open or close are still not working on my CRIO even though real time 8.6 is installed. Attched is a simple vi which works on my PC but not on my cRIO, tried even simplier vis with tdms on the CRIO and it doesn't work. When I try to run the program on the cRIO I just lose connection to the controller and have to reboot it. Any suggests to what I may have missed?

Thanks,

Jevon

I'm not sure what's the problem on your machine, but I could run on my machine with LV 8.6.1.

Would you please describe the problem in detail? like you could enable highlight execution of the VI and run it and observer when running to which node, the connection would be lost or it lost before execution?

I attached the result of running on my target.

Hi YonqingYe

Did you try it on a cRIO 9012? I've attached the software installed on my cRIO incase there's something thats not up to date that i've missed. I've tried highlight execution while running it on the remote device and it loses connection after the tdms open.vi. Error terminal gives error 6 generic file i/o error.

Thanks,

Jevon

I ran into an issue like this and found that the file path for the TDMS open has to have a lower case 'c' as in 'c:\' instead of 'C:\'

You will still get an error on the close, but the file I/O works.

Good Afternoon JChec,

All that I changed was the file path to c:\name.tdms and your VI runs perfectly on my networked cRIO-9014.  I attached images of the modified Block Diagram, the software versions I have running on the cRIO, and the FTP directory in a web browser.

As jkurtw stated, try changing your C to a c.

Hi JChec, I tried 9012.

Hi jkurtw, the problems you described will be fixed in the next version. Hopefully, you already found the workaround.

hi,

Thanks for those replies... honestly never thought to change the case there. Thanks, that works!
