8.6 Preparing the CFU for commissioning
8.6.1 Rules for device names
A CFU must have a device name so that an IO controller can address the CFU as an IO device.
This approach was chosen for PROFINET because names are easier to understand than
complex IP addresses.
The device name must be unique in the PROFINET IO system.
