How to use DAQmx Read to measure multiple analog channels

You posted to the wrong board. I have asked the moderator to move this thread from the LabVIEW board.

Hi,

I have a chassis and NI module which are cDAQ-9171 and NI 9205. (I use Labview 11.0 version)

I try to get two analog input values from different two analog chanels of NI 9205. Unfortunatelly, it is dislayed the same error. (Screenshot is in attachments).

Also, i send my project file in attachments to you for making clear everything.

Thank you in advance for your interest

Best regards,

Serbay Özkan

Dear KoenR94,

I have a very similar problem. I read from two channels but I wish to have two different graph indicators for each channel. However my daqmx only gives me 1 output data that I can plot. Any suggestions?

I would use the split function to get both signals.

Hey, did you get the solution? I am also finding similar problem, reading multiple AIs is giving error using python.

You need to put all the channels into a single task and not create a separate task for each AI channel.
