Just to clarify, the version of the NI-ELVIS software that you may have is not the reason for the missing VIs in the Quanser program you downloaded. The VIs in question are included as part of the LabVIEW PID Toolkit, which I'm assuming is not installed on your machine. However, these particular VIs (Integrator, Transfer Function, etc) are fairly out of date, and they are only included in the PID Toolkit to support legacy code. I'm not sure if you have access to the PID Toolkit (it is also included as part of the LabVIEW Real-Time Module), but I would not suggest purchasing it just to get this Quanser code working.
If you are going to be focusing on simple open-loop control of the Quanser DC Motor, you could start by looking at some of the basic DAQmx examples. Driving the motor at a certain velocity would just require supplying a constant voltage through a DAQ output. If you want to do more advanced closed-loop control, the LabVIEW Control Design & Simulation Module might be worth taking a look at. Take a look at the 3-hour Control Design & Simulation course here. It is written specifically with the Quanser DC Motor board in mind.

Thank you PBear and Chris for your responses, I appreciate the help. I do not have the PID Control Toolkit, as you guessed Chris, and that was what was preventing me from using the Quanser DCMC Trainer. I will try using the Control Design and Simulation Module and let you know how it goes. Thanks again.

Ansel, Did you solve the problem for the missing VIs when running the NIELVIS Quanser DC motor training material?
I have the same problem I can't find transfer function (DBL).vi

The Transfer Function (DBL) VI should be in the following location after installing the PID toolkit: C:\Program Files\National Instruments\LabVIEW 2009\vi.lib\addons\control\advanced\continuous linear.llb
I hope this helps!
