Dear Sir,
In order to get your board working with labview it is important to check whether it is working with the driver (NI-DAQ). If this board is not working with labview possibly it may not be properly installed. I am appending a link to our DAQ installation wizard where you will find step by step with screen shots the procedure. Just select the operating system you have and your board (Lab-PC plus)

Once you are sure that the board works properly with the driver, Labview will take the device number assigned in the driver (Seen at the Measurement and Automation Explorer: MAX. All the rest depends of which task would you like to do.
Hope this helps.
Thanks for contacting National Instruments!
