maintain analog out after vi finishes execution

I am trying to test some hardware using LabVIEW, TestStand, and a PXI chassis. The PXI chassis has an analog out card that supplies a signal to a device, that I then read in via USB.  I have developed a TestStand sequence that has three steps. 1) set up an AO task, and run it. 2) read the device to see if it interprets the signal properly. 3) Close the task from step 1.  I created a run continuously task in Max. The problem is, when step one finishes, the analog output generation stops. I tried to sustitue the DAQ assistance, and the same thing happens unless I keep the DAQ assistant in a loop, which isn't going to work, obviously, because then step one will never finish.

 

Is there a way I can tell my AO PXI card to generate a signal until I tell it to stop, without looping inside a called VI?

Can you share some code?

 

I would suggest opening up the LabVIEW Exmaple Finder (Help->Find Examples) and do a search for Voltage - Continous Output.vi.  It is an example of having an analog output re-generate.

Here is the VI I am trying to use.

 

How do I get this to continue to output the signal after I exit the TestStand step?
