TDMS on Mac

[Matt_W1]

I can't seem to find the tdms (nor tdm )file functions on the mac version of labview 8.2.1 (on OS X 10.4.10). It's been reinstalled twice (uninstalled using the shell script on the installation DVD). If I load up a VI that uses the tdms files that I've created in windows, the icons for the TDMS functions show up but labview complains about unwired inputs (even if there are none). I'm guessing that tdms just may not be support on mac os x.

Matt,

I found a couple of Corrective Action Requests (CARs) in the database saying that the tdms file functions do not work properly with MAC/Linux OS.  This is targeted to be fixed in future releases of LabVIEW, and is a known issue.  I apologize for the inconvenience, and good luck with your applications.

Hi Matt,
I have some information that could be useful regarding the TDM files.  The technology behind TDM is a DLL and DLLs are not supported on Mac or Linux thus we do not have support on these platforms for now.  NI currently does not support TDM on Mac or Linux but this is something we are investigating for the future. I hope this gives you insight into the issue.

I believe the Mac and Linux equivalent to .dll's is .so files (there might be some key differences I'm unaware of though). I figured the problem was due to the only the PC having NI USI support. I was hoping that since the TDMS functions are separate from the storage vi's that it wouldn't have a NI USI dependency (I don't know if it does or doesn't). I've worked around my problem for now (by converting the files on a windows computer first).

Do you specifically need TDM (or TDMS) or do you have an application which needs more speed/flexibility/hierarchy than a simple text file?  There are lots of options if we know what you are trying to do.

I don't know if you are still experiencing issues.  Above is a link to a free download to a VI based TDMS API.  This allows use on all platforms which LabVIEW is supported.  Hope this helps.

Does Labview 2009 now have native TDMS support?

I read through the release notes etc., and there're hints of TDMS on Mac, but it's unclear.

LabVIEW 2009 doesn't have native support for TDMS, except the VI-based TDMS functions.

What in the world does that mean?!  Are the TDMS functions supported on the Mac platform for 2009?  Is there any possibility that this will be supported in the near term?  If not, this incredible format has been rendered unfortunately useless due to the proliferation of Macs in our group.

I'm afraid you can't use the TDMS primitive nodes  (which are in programming->file I/O->TDM Streaming palette) in LabVIEW on Mac, but you can still use G-based TDMS nodes. That is to say, you can still write and read TDMS files on Mac with the basic functionalities.
