(1) PC work as Server, ETH Adapter CN work as Client

The most economical way to achieve the remote communication in the Internet between the PC

and S7-300/400PLC is that set the ETH Adapter CN as the client, set the PC as the server, install

and run the DDNS software on the PC, and set the Port mapping for PC on the router of PC side.

As shown below:

Set ETH Adapter CN network parameters, the gateway must be the same as the router connected

with the ETH Adapter CN, here you still need to properly set the IP address of DNS, different

cities have different DNS Server IP, you can use all, but usually choose the local DNS,you can

search these addresses from Internet, also can find them from the router which you are using.
