NI-DAQ mx 19.0

[mbour]

Hello everyone,

i installed the tool NI-DAQmx 19.0 to use the device USB-6001 with OTX.studio.
Now I want to know which DLLs and functions of NI-DAQmx 19.0 can be used, which can be also called via OTX, so that I can read for example an ECU voltage.

Thanks for your help.

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 http://www.ni.com/tutorial/5409/en/
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
