Hey BerkeleyBear,
Are you trying to simulate in LabVIEW? If so, you would open your session with the "Initialize with Options" VI instead of the "Initialize" VI, and use the options string to set up the simulation.
For a 5110, the string would be "Simulate=1,DriverSetup=Model:5110;BoardType:PXIe", and so the code would look like:
