Morning everyone, first post and new to LabVIEW. I have included the files I have for this project in hopes that someone can help.
What I am trying to do is acquire, on a continuous basis, 6 temperatures, 1 motor speed and 1 motor torque measurements from my lab set-up. Using the Data Acquisition assistant (twice) I was able to view the 6 temperatures on a waveform and then separately the voltage readings for motor speed/torque on a second waveform. When I put the two on the same VI only one of the waveforms is displaying data. Could someone review what I have done or just give feedback on what to look at to correct this?
Ultimately in the end I want to chart data over the length of the experiment, display the current reading and record the data into a file for later access or manipulation.
I sincerely appreciate your help,
Jason

Are you getting any errors?
Do you know if you are getting any errors? You have the automatic error handling disable in the VI, and you don't have any error indicators wired up to your DAQ assistants. So I think you are getting errors and just never see it.
The error you'd likely be getting is one that says a resource is reserved such as -50103. You can't have multiple DAQ assistants using the same DAQ card at the same time.
