Hi mbour,


at first the integration of the NI-DAQmx into OTX driver happens through the DAQmx C-API.

The DAQmx C-API is integrated by using the header file and library supplied in your National Instruments NI-DAQ installation folder:

e.g.: C:\Program Files (x86)\National Instruments\NI-DAQ\DAQmx ANSI C Dev

You have two options to use this library:

  1. Either you can use this library directly: Using NI-DAQmx in Text Based Programming Environments - National Instruments
  2. Or you are creating a dll wrapper What is a Wrapper DLL and When Do I Need One? - National Instruments

For further information on how DAQmx is integrated in OTX, please reach out to Softing directly.
I hope this helps you.
Best regards
