New user to Labview. Need help with TDMS

Solved!
Go to solution

I am trying to read data from 30 thermocouples, view it in real time on my interface, and store it for further analysis. Sales guy suggested I use TDMS as it would display the information in the same manner as if I were to right click on a waveform and click "export to excel" (30 columns representing each of the thermocouples and a column for time). The test would run for an hour or so and each channel would log data at one sample per second. I have tried to make this parameter adjustable on the interface as well as add a clock that could be adjusted to set test durations but too advanced for me as I have only been using labview for a week or so.

 

I have a code that worked fine, until I put in what I thought was acceptable code to store to a TDMS. Now, the code will still run but seems as if no data is being read. Is there an easier way to accompish this task or am I simply overlooking something very simple? Thanks for the help!!

Your logging mode ring seems messed up somehow.  There should be 3 options, but you only had 2.  That should be a constant anyways.  You want it to be set to Log and Read.  You probably had it set to Off, which means the data will not be logged.

I took the liberty of cleaning up your VI some.  You had way too much on your front panel.  It was also thrown all over the place.  Group similar things together so you can easily find what you are looking for.  You also had a bunch of indicators there that the only reason for them is debug.  That's what probes are for.  I also condensed your block diagram.

 

Hope this helps.
