NOTE: The Profinet name of the gateway cannot be changed via the web interface of the gateway. A Profinet chip is, which stores the name internally.
For Profinet, the name should be assigned preferably by the Profinet controller, respectively the corresponding management software. This is usually a Siemens PLC with the management software „Simatic Profinet Step7 V13 (TIA Portal)“.
In the function manual „Profinet with Step7 V16“ chapter „Device name and IP address“ you will find more about this: https://cache.industry.siemens.com/dl/dl-media/856/49948856/att_1004382/v6/129453992715/de-DE/index.html#5cba891503bfb870db8843063fc4243a
