IRC5 Networking - Only LAN Port

Hello everyone,

I am configuring the communication port of an IRC5 controller to integrate it with a Siemens S7-1200 PLC using PROFINET. However, upon inspecting the IRC5, I noticed that it does not have the LAN1, LAN2, LAN3, or WAN ports. There is only a single port labeled LAN.

Given that:

a) Is it possible to configure this LAN port to work with PROFINET?
b) How can I perform this configuration? Is there a technical manual available?

I would appreciate any help you can provide.
