Data from Kuka Robots

Has anyone had experience getting data from Kuka robots? I'm unfamiliar with these and do not know what communication options they have. We are looking to get position and hour information from KRC4 controllers.

Maybe something like this?

That definitely looks like the easiest option for us. Thanks!
