extract single channel from DAQmx Task

[djroseman]

Hello,

I have created a DAQmx output task, which contains two channels.  Is it possible to extract individual virtual channels from the task to be processed by two parallel processes?  I have tried bringing out the Channels Property using a Task Property Node, but I then get the error that the channel is not part of an active task (see attached snippet)

Could anyone advise on a better approach, or how to acheive this functionality - if it is possible?

Regards

Dave

Sorry, that VI does not make much sense. You have to use a single DAQmx Write for both channels and for 1 Sample mode, you simply have to build an array of the signals as shown below.

Apologies, I appear to have had a temporary brain bypass...

You are correct, I understand what you mean - the task contains labels to the channels, rather than the data, yes?

Correct.
