Citect Communication Error with M340 PLC

[TahirQ 0]

I recently posted about opc server Communication Failure with My PLC. I have now decided to change the approach. I am now connecting Modicon M340 PLC using ethernet to My HMI PC directly. I have set P34 2020 to default IP Address which is 84.15.70.234(calculated using its mac address). Now In Vijeo Citect to setup Ethernet communications, We need to configure boards and ports. In Boards I enter Board type: TCP/IP and Address as 0. In ports I enter port number:1 and in special opt I enter -I84.15.70.234 -T. In Express Communication Wizard, I give TCP/IP information as follows: IP: 84.15.70.234 Port:502 TCP Still I am getting the error that says parameter is not correct. Can somebody point out where I am making a mistake in all of this?

I don't know much about the Vijeo Citect or the M340 PLC. But what I experienced with other equipment is that port 502 is used for Modbus TCP/IP. In some equipment isn't the port open for use, unless the system is capable to use the Modbus communication.
