Data Acquisition through Two NI PXI 4071

[Shaheen]

Hello Everyone,

I was taking data with one NI PXI 4071 (the code is attached) but now I want to acquire data through two NI PXI 4071.

I have both NI PXI 4071 in chassis connected to PC. Can you please guide me what do I need to change to do so.

I will really appreciate your help.

Best Regards,

Shaheen.

Hi,

I think you basically just have to copy your code, to do two simultaneous tasks.. (see attachment) and then just choose the second pxi for the second task..

Hope this helps..

This assumes you do not want to synchronize the two boards so they take data at the same time.  If you want to do this, check out the DMM examples.  If that does not work for you, you may want to post your question in the DMM board.

I tried to copying the same code but it collects big data and runs out of memory, so synchronizing would be a great option. 

I will look at DMM examples and my be posting this question on DMM Board.

Thanks a lot for your advises.

Best Regards,

Synchronization will not necessarily take care of the large data issue.  Take a look at Managing Large Data Sets in LabVIEW.  If you continue to have problems, leave a link from this thread to the DMM thread and continue the conversation there, hopefully with code examples.

Please enrich me with your guide lines at the following link in DMM board.

Thanks.
