Hi,
I'm working on a project where I'm connecting a Momentum PLC to a SCADA system. The PLC was installed by an outside contractor and comes to an HMI via ethernet->fibre->ethernet. The original discussion with my site contact led me to believe that I'd be getting an ethernet connection from the PLC (so Modbus TCP) and use a small Prolinx protocol converter to dump DNP 3.0 over serial to the SCADA.
Now they want to re-do the fibre connection to make it the same as everything else in the plant. The fibre will come into a patch panel converting to serial, then they want to install another media converter to give me back the ethernet. So from the PLC to the protocol converter it will be:
ethernet->fibre->serial->ethernet
I guess what my question is, what happens to the Modbus TCP when it's put through the serial to ethernet media converter (not a protocol converter? What comes out the other side? Will it still work with the protocol converter?
