Issue Details

I do not want to stream all the values acquired with my NI DAQ Device to the hard drive. How do I configure DAQmx Configure Logging (TDMS).vi to only stream the values I want?

Solution

The DAQmx Configure Logging (TDMS).vi does not include the function to stream to the hard drive selectively.
In the case that you need manipulate, select or order the acquired data you have the following options:
  • Use a combination of the DAQmx Read VI and VIs from the TDMS API. However, the tradeoff here is that the data will not directly move from buffer to hard drive.
  • Use the TDMS API to load your data after it has been saved to the hard drive. You can edit your data and create an updated Log file.
