Hi Haider,
For the PXI 6289, did you right click on the PXI chassis under Remote Systems in MAX and click on Find Devices? If you haven't done that yet, it should bring up all the devices in the chassis.
As for deploying you VI to the Real Time Controller, you will first have to create a realtime project. Then you will have to build a realtime executable and set that executable as a startup vi. After that deploy it to your realtime target.
For the specific steps, you can go into the LabVIEW help and look for Real Time Modules in the index section of the help. You can also do a search if you like for the same key words.
Hopefully this will help you get on your way.
Thank You,
Nick F.
