9220 with cDAQ 9178

[AnuSingh]

Hi,

I am new to LabVIEW programming. i am trying to capture multiple analog I/p via 9220. I have attached snippet of what i am actually trying to achieve. basically as per my application i have to keep acquiring data in parallel from each analog channel. currently i am getting error if i try to acquire from two or more channel as same time. 

any suggestion on how to do that effectively will much appreciated.

This happens because there can only be one DAQmx task (your purple wire) per module. In this case, I recommend doing channel expansion, where you can have more than one channel per task.

All the best,
