simultaneous analog input and analog output

[akeiw12]

Hi, I'm new to LabVIEW and am trying to figure out a simple program.  I need to generate a sine wave and output it through an anlog output channel, which is connected to a motor, and then I have the output of the motor circuit connected to an analog input channel, which needs to be sent to a waveform graph.  I haven't used LabVIEW much, so I tried using DAQ Assistants to connect my analog input and output channels.  I have one DAQ Assistant for the analog output, and one for the analog input.  However, I've found that only one DAQ Assistant can be run at one time.  Is there a way that I could connect these two DAQ Assistants at all, so that I could run them simultaneously?!  I've never programmed in C++ before, and I'm not really sure how to do much else in LabVIEW, but if there is a simple solution to this, I would be willing to give it a shot!  I appreciate the help!

Thanks a lot,

alissa

Which DAQ card are you using??

with this info, we can point to a specfic solution

There are examples shipped with LabVIEW.

In it, go to Find Examples>> Hardware input output>>DAQmx>>Synchronization>>Multifunction>>look at " Multi-Function-Sync-AI-AO.vi"

This vi will do just what you want to achieve

Any doubts, do ask

Thanks for this! Although extensive, the help in LabVIEW can be hard to negotiate.

Hi,

I am also trying to simultaneously read analog input and send analog output with LabVIEW 2012 and an X-Series Multifunction DAQ. I tried to look for this example but in the Synchronization folder all I have is Analog Input Synchronization examples. I tried to looking on ni.com but didn't come up with anything. Is there another way I can access this example? Or is there an example in the newer version of LabVIEW that would help me with this?

Thanks

To find those older examples start here.

This VI does not exist.
