Hello Xu,
It depends on what version of CVI you have.
If you have CVI 7.x, there is no direct Real-time suppport. You
would have to use LabVIEW and LabVIEW Real-time to embed an application
on the controller.
If you have CVI 8.x, you will only need LabVIEW Real-time in order to develop a CVI Real-time application.
