Modicon TSX Premium PLC.Protocol

I am Looking for the Details of the Modicon TSX Premium PLC. Basic communication setup for this PLC using the PL7 Pro Software is already established. I had connected it to the PLC’s TER port and able
to go online with the PLC using PL7 Pro Software. But I don’t know what are the protocol details for the TER port. My intention of doing this is, I want to communicate further my SCADA with this PLC using the OPC Driver over the Modbus Protocol. I hope this clarifies what I require. So Please look if u can help
me out in anyway.

The TSX Premium TER port protocol is Uni-Telway. For Modbus, you will need to add an option port, either the PCMCIA card or the SCY module.

Does your OPC support Uni-Telway?
