DAQmx integrated logging

[jharris66]

Hello,

Does the integrated DAQmx TDMS logging support writing data in a ring buffer scenario where old data gets overwritten?

Thank you,

I'm not totally sure what your question is.  But here is my understanding.

If you set the DAQmx Configure Logging to just log, then you can't do a read with DAQmx Read.  The data just goes straight to disk.  I'm not sure how NI does this, but it just freaking works and you shouldn't have to worry about having the buffer overwritten.

If you set the DAQmx Configure Logging to Read and Log, then the logging happens when you perform a read.  I would assume that if you get the data overwritten error, then you just lost data.  The lost data will not be in the TDMS file.
