Adding another subnet to the PLCnext

Hi,
I would like my AXC F 2152 to be accesible from two diferent subnets, so I am planning to use an AXC F XT ETH 1TX module. But I have a couple questions:

                              * As I understand it, this module acts as an additional ethernet port with its own MAC address, so I would make the PLC participant of 2 different subnets, making it possible to, for example, accessing the HMI running on the PLC from both of them. Am I right?
                              * Would this PLC + XT ETH work as a switch too? So it would be possilble to access the devices from the other subnet through the PLC? I guess not because it would have to act almost like a layer 3 switch, but just to make sure of how it works.

Thanks in advance!

Am I right?Yes.

There is a knowledge base article that explains how to set up an AXC F 2152 with AXC F XT ETH 1TX as a router:
Knowledge Portal ese portal The information in that article doesn’t use anything that’s unique to PLCnext Control devices; a similar configuration could be used on any Linux device with multiple NICs.

Everything is clear now.
Thanks for you answer, Martin.
