to distinguish between two different channels from DAQ

[vaib]

Hello everybody I have a labview program which collects data from 3 different channels. Is there any way by which i can seperate the 3 signals in the block diagram?? Thanks in adavance for your prudent advices.. vaib

Hi vaib,

how do you collect them? If you use the DAQ-assistant, then you can use the split signals function (you can resize it).

Thanks for replying I am collecting signals from 3 pressure sensors and passing it to DAQ through a signal conditioner.

Hi vaib,

do you mean like this? After the split signals function you have your three signals separate. Is it what you need?

yeah that is it thank you for your valuable advice. I have one more question though, I want to control my data acquisition process using a physical device, i.e, if an external (physical/material circuit, which is connected in one of channels of the DAQ) is open I want data acquisition to start and when the circuit is short I want it to stop. Is there any way to do this I am attaching my vi fo you to have a look. Thanks again for your continued support Vaib

Hi vaib,

you can use another DAQ function and configure a digital channel. You can then connect this output to the case structure. What about using DAQmx functions, did you think about it?
