I want to write data in tdms file. I have 4 loops which is 2 producer and 2 consumer. I need to write the data in same tdms file in two groups. How can i do it?

test Vi is attached so idea should be clear

Try the attached modification.
Here is a snippet:


Necessary Changes:
Open TDMS Reference before loops start.
Close TDMS Reference after both loops complete.

Recommended Change:
Use Share Stop Signal VI to stop all loops while only requiring a single Stop button

If you need to eventually span multiple files  due to file size or just duration of test, you will need a more sophisticated approach.

Good luck!

For those that may not be familiar with Share Stop Signal VI, it ships with LabVIEW and can be found here: <LabVIEW>\vi.lib\ChannelSupport\Share Stop Signal.vi

It is not in the palette, and I don't think Quick Drop finds it, but it is still a handy utility for cases like this.
