PXI-5406 generate waveform after VI closes

[markwysong]

I have a PXI-5406 waveform generator card where I would like to run a LabVIEW vi to set it up and start it, and have the VI stop, but the card to continue its output.  I can do this via DAQmx calls with a PXI-6733, where I tell it not to "autoclose" the references to the 6733, but not for the 5406.  How do I do this?

Hello Mark,

I did exactly what you are describing by simply taking the Fgen Basic Standard Function VI from the Example Finder and removing the last two NI-FGEN VIs that abort the generation and close the session. Without these VIs the generation will continue until LabVIEW closes, even if the VI that started the generation is closed.

As far as getting this behavior and being able to close LabVIEW, you may want to look into creating a C-based executable that generates the desired function and runs in the background on your system.

Let me know if you have any further questions about this.
