Why does the PROFINET switch have its own IP address and a PROFINET name?

The PROFINET switch is a managed switch. The IP address is necessary to be able to address the switch as an active infrastructure component. The website of the PROFINET switch can be reached via the IP address and PROFINET participants (e.g. a CPU or a programming device) can configure the switch and read out information from the switch.

For the purposes of simplifying the IP address in the PROFINET, a device name can be used that is then synonymous in a project for the IP address.
