a) Warning: Before downloading PROFINET IO device names, make sure that
ProfinetCommander is not running or HW Config will lock up.
b) To assign PROFINET IO device names, the PC and the IO devices must be physically
connected to the Ethernet network and operational.
c) In HW Config select a PROFINET IO device and then select “PLC->Ethernet->Assign
DeviceName…”.

and then select “Assign name”.
