Of course you can use ETH Adapter CN to simulate each PLC as a COM port on the PC in order to

achieve the data communication and monitoring operation between PC and multiple PLC s

8. Remote communication in the internet

ETH Adapter CN can achieve the worldwide remote communication through the Internet, it

will use the external network IP address of the router, the router external network address is

different when the router is started every time, because the router will be randomly assigned to one

IP address from the Internet when it 's powered every time, so this will result in trouble for remote

communication through the Internet, There are two following methods to solve this problem:

Apply to buy a fixed IP address from the Telecom or Internet operators, the fee will be higher.

Use the dynamic domain name resolution(DDNS). you can apply for a free or paid domain name

from dynamic domain name service provider, then use domain name instead of IP address; so that

regardless of changes in IP address, domain name will point to IP addresses in real time, like as

we usually visit the website .

Some providers such as Changeip.com and other dynamic domain name (DDNS) service

providers offer free and paid dynamic domain name service, you can consult them for their

dynamic domain name service and charges issue. Firstly you need to apply a dynamic domain

from DNS service provider , and download the Dynamic DNS client software, run this software on

the host of Server mode(PC or router with DNS function).After the client software has been

successfully started, Server host has solved the problem of dynamic IP address. Input the

dynamic domain name in the IP input box of Client remote host, set the DNS server IP address as

the local DNS server IP addresses, then you can use the dynamic domain name to visit the

internet.

In the following example, use our free dynamic domain name:kollew.changeip.com, use the PC in

Server-side and run the dynamic domain name client software, you can also use a router with the

function of dynamic domain name .
