Difference between DeviceNet Lean and DeviceNet

Options
Hi, I´m new in RobotStudio and I trying to configure a DeviceNet network to connecting a ControlLogix 1756 PLC of AB (Master) with an IRC5 controller to command an IRB120.
So the question is what is the difference between DeviceNet Lean and DeviceNet because I don't know which of this option select in the configurations in the RobotStudio software.

Thanks!
