There is an example built into the default programs.

In the default Dashboard About halfway down you'll see a block of variables used on the Basic tab.
In Teleop.vi you'll see corresponding reads of some of those same variables.


Here is another example that places new variables on the Custom tab.
It shows two boolean variables Marc 1 and Marc 2 that are explicitly treated as SD variables.
It also shows another two boolean variables Marc 3 and Marc 4 that are implicitly treated as SD variables.
All four are read on the robot side in Periodic Tasks.
