Dispatch multiple digital input to different VIs in different projects

I have a USB-6259 DAQ, and I would like to acquire several digital voltage inputs from different independent VIs.

 

According to what I read it is not possible to acquire data from multiple digital input channels using mutiple daqmx tasks (even using software timing). As a result I am looking into building a VI which would acquire data from multiple channels using a single task, and into controlling this VI from other VIs using VI server.

 

Has someone done this before ? Is there a better way to achieve the functionality I need ? Thank you very much for your advice.

Hi astralth,

 

I haven't tried the setup you've described but I don't see any reason why it wouldn't work. You could also look into shared variables.
