I cant remember if the Logitech gaming software detects Planetside 2 and has a default Logitech g13 profile. Still, I either made a Planetside 2 Logitech G13 profile from scratch or customized the existing one based on the tutorials. The layout is your typical FPS layout with a few extra controls for when you are in a vehicle and for the abilities each class gets. I have found it worked well for me and gave me access to everything I needed for each class.
Below is a screenshot of the keyboard layout.
