Michel,
The .daq file, where all the MAX information gets stored, is in binary format. You will have a hard time decoding it LabVIEW.
However, you can use some DAQ VIs to get this information.
Under Data Acquisition>>Calibration and Configuration>>DAQ Channel Utilities palette, use the following VIs:
Get DAQ Channel Name
Get Channel Information
Get Scale Information
