Simulated DAQ input state

Hi everyone,

Is there a way where we can chose the state of simulated DAQ cards?

For an example I have simulated NI PCI 6229 and accessing the Port 1 line 0-7, but while running the code the values read from simulated DAQ keep on changing with no control over it. 

Is there a way where I can change the value of each input as per my need, this would allow me to validate my application in a better way.
