DAQ Assistant never builds

[Havells_Drew]

Greetings!

Just starting out on my Labview journey and have run into a little problem.   I'm trying to acquire temperature data from my 9213 via a single slot USB chassis 9171.   Everything works in NI MAX but when I try to build an express VI with DAQ Assistant everything appears to work but the dialogue box BUILDING VI never completes, the progress bar just goes round and round.

I have tried repairing all the NI components, without sucsess, then re-installed everything, then updated NI MAX to the latest version, none of which made any change.

I have attached a couple of pictures, one showing it working in DAQ MX, the other what happens when I build the express VI.   My system is Labview 2014 on Windows 7.

Kindest regards,

Hi Drew,

what happens when you use basic DAQmx functions instead?

Please see this step-by-step explanation! All you need are 3 or 4 functions in a row…

Thanks very much for your reply,   I can get data using the DAQmx functions and the examples so I will be able to continue with my project.   Just a shame I cannot use the Express VI to speed thing up a little 🙂

Thanks again,

Drew

Hi Drew,

Hello,

I too am new to LabVIEW.  I am having the same problem that Drew was having.  I also tried to utilize the basic DAQmx functions, but in order to specify a channel, I must browse>>Create new MAX Channel>>acquire a signal.  This signal is acquired through the DAQ Assistant.  I can't seem to fix it or get away from it! 

What step/s should I take to get the DAQ Assistant working?

Any help is appreciated. 

(I hope it is OK to post this here)

Thanks.

Well, it's preferable to start a new thread. Especially important is to provide details on what you have done. What version of DAQmx did you install? Did you install it after LabVIEW?

And no, you certainly do not have to create the task in MAX or use the DAQ Assistant to create the channels. As you can see from the examples that come with LabVIEW.

Thanks for the reply.

I had installed LabVIEW first.  Then I installed DAQmx 14.2.0

In response to your comment:

     "And no, you certainly do not have to create the task in MAX or use the DAQ Assistant to create the channels,"

I just searched for " DAQmx Channel" in the funtions menu and I found DAQmx Physical Channel.  I see all of my AIs listed!

I guess I didn't realise that I had more options. 

Thanks for your help!
