It will work that way, though the LED will be off for a "1" value and on for a "0". Since the DS's output can source current as well as sink it, I'd connect from the digital output through the indicator to ground instead. That way the LED will be off for "0" and on for "1".
The way you connect it should depend on whether you want the LED to be on or off when the system is reset, before the cRIO software has a chance to control it.
Why is it whenever you tell someone there is a million billion stars in the universe they believe you, but if you tell someone that the bench over yonder has wet paint, or if usfirst.org comes up as the 1st result in Google people have to try it for themselves?
