parallel SCXI calls

[lmd2]

What I would like to do is start a 30 second buffered acquisition on an SCXI-1120 channel, and while the acquisition is happening, toggel a channel of an SCXI-1163R. When I try to code for parallel execution, the switching 'waits' until the data acquisition has completed. I need the DAQ to start first, and I need the switch to toggle within the window of 30 seconds, not following it. Is this doable?

Greetings,

Yes, you can do this. They key is to make your analog input acquisition asynchronous. Thus, "AI Read.vi" will not "block" your other calls to the NI-DAQ driver. You should examine "Acquire N Scans - Async Occurrence.vi". This example is installed with LabVIEW and demonstrates how to program an asynchronous acquisition.

Good luck with your application.
