Hardware and software requirements
1.
Hardware requirements
In order to follow this guide you will need:
1 eWON with an integrated MPI port (for example: eWON 2001, eWON 4101)
At least 1 Siemens PLC S7-200
1 standard Profibus cable to link both equipments
1 PC with internal or attached modem
Software requirements
eWON configuration software:
The eWON is configured through its web server. So all you need is a standard Web
Browser software like Internet Explore r i or Firefo x ii .
Additionally we suggest you to download the eBuddy utility on our website :
This utility allows 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 of your eWON (if required).
Other programming software:
MicroWin Software from Siemens to establish the connection to the PLC.
eWON Firmware Version
To be able to follow this guide, your eWON needs a firmware version 5.5s1 or higher.
A simple way to upgrade the eWON firmware is to use eBuddy, the eWON software
companion.

eWON IP address configuration
Chapter 2.
eWON IP address configuration
2.
Every eWON™ is shipped with the pre-configured IP address 10.0.0.53 and
adm/adm as User Name/ Password.
Probably the network settings of your PC do not allow you to connect to the pre-
configured IP address.
You can find on our website a software called «eBuddy» that will allow you to change
the IP address of the eWON even if your PC is not on the same IP address range.
To change the IP address of your eWON using eBuddy, follow the steps below:
Launch the eBuddy application (eBuddy.exe)
Click on the «Set IP address» link

Once the Serial Number has been entered, click Next .
Set the new IP Address and the Subnet Mask .
Click on Next to launch the update and wait for the eWON to reboot:
