Using software configure scxi 1520 and scxi 1126 into the same task ID

[bedscape]

I have one scxi chassis. There are two scxi module, one is scxi 1520(measure weights),
the other one is scxi 1126, measure frequence. Using traditional DAQ(labview 7),
how to use software configure the two modules into one task ID? They have different parameters need to be set. For the scxi 1520, the bridge style, the filter frequence, for the
scxi 1126, the trigger type, the threshold value. Thanks for your advice!

Hello Bedscape,

If you create a virtual channel for each one of those channels, you can include all those virtual channels when you create the task using AI Config. The "channels" input takes an array and you can include all the virtual channels in that array and they will all be included in the built task.

Thanks. So, I have to use Max? My whole program is kind of using traditional DAQ, not DAQ max. Is that
possible to configure vitural channel in labview using traditional DAQ?

Appreciate.

A littgle confused here. The parameter congigure vi should come before or after the AI Config?

Hello Bedscape,

You can create virtual channels in traditional NI-DAQ. Using Measurement and Automation Explorer, right-click on Data Neighboorhood and create new. This will prompt you for eith DAQmx task, virtual channel or traditional virtual channel. Select the last one and configure your channel. You can then use the IO connectors in LabVIEW to choose those channels that you have created.
Good luck.
