Hi, I am working with a project, where I want to collect data from different types of sensors and handle everything from the front panel.
I have set up a 3wire linear potentiometer to my Ni9201 with an external voltage supply and my programs runs like i want.
But when I try to connect the potentiometer to my NI 9219 and want to use the internal voltage at the module, i can't figure out what i am doing wrong.
Can someone please tell me how to wire up my potentiometer and how to configure the excitation in my Labview program?
Best regards
Morten

I expect that this article: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000x4q4CAA&l=en-US will help you.
Probably you have a (physical) wiring problem.
Beyond that, I'd only suggest that you try shrinking your VI - currently it's hard to work out what's going on where; probably some subVIs would help make everything much more readable.

Thanks for your answer.
I understand that it could seem a bit difficult to read.
My program allows me to choose which port from my DAQ the sensor is connected. Thereafter calibrate the sensor and reset to a starting point.
The data to save is distance moved, min and max value for this sensor.
My problem is that I can't get any voltage out of the NI9219 with my Labview setup.
So I am looking for a guide to use the correct property nodes. Currently, I can't measure any excitation as it is.

Connect to pins 3 and 5 for excitation then its just a matter of changing the c series module property settings in your project file.
