Fibre Optic communication

Hi Everybody

There is a ring network of six PLC TSX Premium (Schneider Electric) connected through Fibre Optic and connected to a SCADA. Presently, an additional Modicon M340 and an HMI is installed for a new machine. I would to know if we can use the existing switch nearby used for a TSX Premium to connect the HMI Ethernet Port to it and access the HMI via web browser in the central room through the existing switch therein.

Thanks and Regards

Probably. Not much detail to go on but it will likely work.
