Reading TDMS file in DIADEM whilst the data are sitll being written to the TDMS file in LabVIEW.

Hi,

As in the subject.

Can I read in DIADEM the TDSM data still being generated in LabVIEW? I'm doing long tests and I'd like to observe some statistic whilst the data is still being generated and written to tdms file.

Thanks

It depends on the writing code.

There are blockin and non blocking ways.

DIAdem tries to open the file readonly.

In addition it will show the length of the moment it was opened and only refresh when the file is reopened.

If you are doing high speed logging, accessing the file might cause performance issues.

So the answer is: You have to try if it works in your case.

OK, thanks.

But how I can use write to the file in unblocking way in LabVIEW? I can't find obvoius option in the LV.

Hi Mimi,

When I have tried this in the past (years ago), it just worked with not special programming required.  If things have changed and that is no longer the case, I suggest you raise this question in the LabVIEW forum.
