Hi,
I have to pilot with Modbus over TCP some PLC and homemade controllers, and send files from the work computer to the machine. The machine will embed several controllers and a computer (it will send Modbus instructions). I don't want the controllers to be accessible from a different computer than the machine one.
I need the same diagram as the following one, but with Modbus TCP instead of Modbus RTU in the machine:

Is that possible to isolate two Ethernet network with the same computer?
I mean:
The machine computer can communicate with company network and receive files from workstation.
The same machine computer can send commands over Modbus TCP to PLC and controllers.
PLC and controllers have to be unaccessible from the workstation directly.
I have to use Modbus TCP instead of Modbus RTU in the machine, because we need to use PLC with Modbus TCP. And the controllers muss be used in other parts with Modbus TCP.
I hope the message clear and the project feasible.
Thanks
Guillaume
