Pause Trigger Multichannel

Solved!
Go to solution

Hi everyone,

 

I am a very beginner with LabView. I am able to acquire multiple analog signal from my PCI 6221 using DAQ Assistant but my requirement is to only measure all of my inputs with pause trigger i.e. I need to acquire data only when my e.g. PFI10 is Hi. Whenever the PFI10 is Lo, the measurement pause.

 

I've found an example to achieve pause trigger here. However, this is only for 1 channel unfortunately. I do understand about the flow, but I've tried many times to add another channel to my acquisition but not successful. Maybe my knowledge is limited and only able to start the project from DAQ Assistant but not from this type of project.

 

I tried to add another channel at DAQmx Create Virtual Channel.vi but it couldn't accept two input. Maybe I need some kind of multiplexer?

 

If the above matter can be done, how to add another Measurement at DAQx Read.vi inside the while loop?

 

Can someone point me on how to add channels ( i need at least another 2 channels, analog) on this vi? I believe, other user who are in beginning stage like me will benefit from all of your respons.

 

Kindest regards,

Haye

Hi,

 

Found the solution (attached vi). But this is only from 2 channels.

 

Kind regards,
