Modbus RTU/TCP Gateway on CCS Ethernet Proto please help

[gomond]

Hello I am attempting to create some MODBUS RTU -> TCP gateways or converters for my home automation project, as MODBUS seems to be the way to go.
I am using a Mitsubishi FX3GE PLC as the main controller and want to run MODBUS over ethernet and ZigBee. I am making progress with the RTU over ZigBee, But converting the RTU to ethernet is puzzling me.
I read a forum stating that MODBUS TCP is now supported via the CCS stack but there are no examples to learn from. I have learned heaps from the ccs modbus serial examples that come with the compiler, but would be very great full for any help with the TCP side, as my goal is to use the CCS ethernet pro to board as a serial to TCP gateway.

I know that you can buy one, but where is the learning advantage in that.

Thanks in advance.

Thanks CCS for sending me the TCP examples,
Now its just a matter of mapping and working out the arbitration issues.

I guess it's probably just a matter of queueing and re-transmitting.
