would a managed switch help in this situation?

Hello all,

I have a robot which has only one NIC that has two virtual addresses:

a) 192.168.1.X
This address will be used to connect the robot to a PLC.
b) 192.168.1.Y
This address will be used to connect the robot to the customer LAN.

Would a managed switch be able to separate both connections?

LAN (192.168.2.X) --A--- SWITCH --B--- ROBOT (192.168.2.100 & 192.168.1.100)
                           |
                           C
                           |
                          PLC (192.168.1.101)

I would like to ensure no traffic that should go from B to C would reach A meanwhile any traffic from B to A would never reach C...

Do the managed switch manage the port (rj45) or does it manage the IP addresses that reach the switch through the port?

In the first case it would not work as a single cable would take two IP addresses to the switch from the robot, but in the second case it would do what I do need.

Can this be done with a managed switch?

summarizing: 1 physical NIC, two IP addresses linked to that NIC, two separated network paths. Would that work?

Thank you all!
