TDMS Write comment in the middle of the Data Acquisition

[sunny_304]

Hello,

I am currently using TDMS for my Data Logging. Currently I am logging data from a Keithley module via GPIB connector.

Essentially I want to log data in intervals and while logging the data I want to have a comment section where I can write changes which have been made.

It logs in minute intervals and I want to add comment in minute 5 for instance. What is the correct way to implement it.

Thanks

I would use a loop that is dedicated to writing to the TDMS file.  You can then send commands/data to this loop through a queue.  You could one command for writing your DAQ data and another for the comment data.  I would log all of the DAQ data in one group and the comment data in a second group.  That will make your file a lot easier to understand.
