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 DDNS service
provider , and download the Dynamic DNS client software, run this software on the host of Server
mode. 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.net, 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 .
1.STEP7 Micro/WIN software setting
Select RS485 communication mode switch on the ES-ETH-PPI to "10bit" , use the no parity 10 bit
communication mode,then use the setting software to set ES-ETH-PPI serial port parameters as
9600bps,8N1 (8 data bits, no parity, 1 stop bit).
When the VCOMM virtual serial port software running on the PC simulate ES-ETH-PPI as the
COM port on the PC, the next using is just like PC / PPI programming cable, but you should set the
local connection in the “set PG/PC interface” menu of STEP7 Micro / WIN software as “modem
connection” mode.
