3. Software requirements

eWON configuration software:

The eWON is configured through its web server. All you need is a standard Web Browser

software like Internet Explorer or Firefox.

Additionally we suggest downloading the eBuddy utility from our website

http://support.ewon.biz/

This utility allows you to list all the eWONs on your network and to change the default IP address

of an eWON to match your LAN IP address range. With eBuddy you can also easily upgrade the

firmware or make a backup of your eWON (if required).

eWON Firmware Version

The screen-shots of this guide reflect firmware version 6.4 S2 (2012), but you can expect the

basic principles to remain the same in earlier/later versions.

4. PLC protocol compatibility

The table below shows the Siemens protocols that are supported and, for each of those, which IO

Server you need to use inside the eWON to connect your Siemens PLC.
