Sorry elyas;
I do not fully understand what you are trying to say.
PL7 is a programming language used for Schneider Micro and Premium PLCs. You use it to plan and execute the control functions of your PLC. Amongst other things you can use it to program the communictaion functions for your PLC.
With your PLC you have a communication module (Ethernet) ETY110ws. I am not familiar with it, but Ethernet modules can exchange data with specific protocols. If both Ethernet modules do not share a common protocol, it becomes difficult (possible, but more difficult) to setup data exchanges between the two.
Since Siemens proposes a solution for Modbus/TCP on the CP 343-1, if you can confirm that your ETY module "talks" also with Modbus/TCP then you have a possible solution.
Please check if your module supports the Modbus/TCP rotocol,so we can continue the discussion.
Hope this helps,
