Now open the dialog window for the WAGO BootP server by going to the
Start menu on your screen surface, menu item Program /
WAGO Software / WAGO BootP Server and click on WAGO BootP
Server.

Click on the "Start" button in the opened dialog window.
This will activate the inquiry/response mechanism of the BootP protocol.
A series of messages will be displayed in the BootP server. The error mes-
sages indicate that some services (e.g. port 67, port 68) in the operating sys-
tem have not been defined. DO NOT BE ALARMED THIS IS THE
CORRECT OPERATION FOR THIS EXAMPLE.

Now it is important to restart the controller by resetting the hardware . This
ensures that the new IP address will be accepted by the controller.
To do this, cycle power to the fieldbus controller for approximately 2 sec-
onds or press the operating mode switch down which is located behind the
configuration interface flap located on the front of the coupler.
Following this, you should see a reply from the buscoupler stating that the IP
address has been accepted (no errors). The IP address is now permanently
stored in the coupler and will be retained even following the removal of the
coupler or a longer voltage failure. The only way the IP address can be
changed is by using the BootP software again.

Subsequently, click on the "Stop" button and then on the "Exit" button, to
close the BootP Server .

Testing the function of the fieldbus node
1.
To test the communication with the coupler and the correct assignment of
the IP address call up the DOS prompt under Start menu / Program / MS-
DOS Prompt.
2.
Enter the command: "ping" with the IP address you have assigned in the
following form:
ping [space] XXXX . XXXX . XXXX . XXXX (=IP address).
