Just to say things differently, on the RobotMain VI, click on the run button on the toolbar, next to the Stop Sign. This will download the VIs to roboRIO RAM and keep a debugging connection open. As mentioned, you can open panels to see values flowing in and out. You can see the run buttons pulse between reserved and called. You can open a block diagram, right click on a wire and open a data probe. You can also right click on a function or wire or diagram to set a breakpoint.
