Hi Ajinkya,
In order to interact with data dashboard you need to publish the data from the real-time portion of your system to the network. To do this you need to use network published shared variables (NPSV).

I would also read through chapter 4 from the cRIO developers guide which will help explain a lot of different networking options.

It is important to note that only NPSV are able to connect with data dashboard which is explained below.

Finally, to use NPSV on an sbRIO/cRIO you need to make sure the variable engine is installed on the sbRIO which I believe is covered in the cRIO developer guide but I have also provided a link that covers adding/removing software from an sbRIO/cRIO.
