MODBUS TCP on optic fiber with M340
Hello,
I'd like to ask for a technical confirmation on using MODBUS TCP in a M340 + Fiber Converter Card (BMXNRP0200C) or Switch (ADAM 6521) + Fiber Optic patch cords and cable topology to communicate with a SCADA system.
The main objective is to provide a fiber optic connection point inside a control panel because it is located in a area prone to electrical interference. The protocol to be used would be MODBUS TCP. We have two simple topologies in mind but we are not sure if they are feasible. So i'm asking for a little support about it.
Considering the following simplified topologies, am I able to use MODBUS TCP to communicate from the M340 to the SCADA workstation with no problem? I'm not sure if the protocol allows this kind of change on the physical medium like if it was pure Ethernet.

Provided none of the convertors block TCP port 502 the transfer of Modbus/TCP will be oblivious to the fact it is changing medium.
I have used the ADAM units before without issue
