TDMS database and treat its values as real time data.

[reza_amin]

Hi,

I'm newbie in using labview. Actually I wanna import data from TDMS database and treat it as real time data. Although I have done the first part which is importing the data inside the program by reading TDMS and selecting channels and groups, I couldn't find way for second part which is treating data as real time one. I tried Build Waveform, but it didnt work. Would you please help me to solve this problem ? I appreciate your helps.

reza_amin,

I don't understand your word "build waveform". If you write waveform data to a tdms file, you will read waveform data directly from the tdms file.

If you are using LabVIEW 2012 (download from www.ni.com/trylabview), you could find a tdms example VI in "C:\Program Files\National Instruments\LabVIEW 2012\examples\file\plat-tdms.llb\TDMS - Concurrent File Access.vi". This example VI demonstrates how to write Sine Waveform into a tdms file and read the Sine Waveform from the tdms file.

Hope this helps and enjoy your LabVIEW journey. 🙂

Best Regards,

Bo Xie

For generating different waveforms look into Waveform Generation Functions.These Functions  are in signal processing palette

Functions -> signal Procesing->Wfm Generation.
