NI9476 does not output correctly in a subvi

Is there a reason you don't want to just wire in the Device name directly as you do with Do1 and Do0? Whenever you can directly wire something, that's always the best way.

In the main program I call the Digital Outputs and Digital Inputs from a few different places. So if I have 4 DO modules and 4 DI modules that I call in 4 different places that would be 32 different names to match to 8 cDAC module names. It would be much cleaner to just define the 8 names just once (if it worked reliably).

Ok, I can see why having so many wires would be messy and difficult to read. That would still make your program perform the best, however, so it's still what I would recommend.

Another thing you could try is making the name into a local variable. I'm not sure if this would work much better than the property nodes, but it could be worth a try. They are still slower to update than direct wiring. I don't think it would ever output blank values, but then I'm not sure why your property node is doing that either.
