Using two DAQ assistant at the same time

[yatang]

Hi there,

I need 14 channels to read voltages at the same time, thus I plan to use two NI-6009.

However, I don't know if it's possible to use two daq assistant modules in labview at the same time.

The attachment is my current code. Can I put two daq assistant in a single loop?

Thank you!

You can have two DAQ Assistants, one for each DAQ board.  You will need to combine the signals after they are called.

For ultimate flexibility, do a Web search for "Learn 10 NI-DAQ Functions", read the artucle it references, and vow to Never Again Use the Dreaded DAQ Assistant, and its Evil Twin, the Dynamic Data Wire.  It will handle the two USB6009's with ease.  You can also handle simultaneous data writing using a Producer/Consumer Design pattern, very flexible and tailorable.

Thank you so much! 

Or can I simply use a 16 channels device instead like NI 6211?

Thank you Bob!

Can I simply use a 16 channels device like NI 6211 instead of two 6009?

Yes you could.
