Fieldbus coupler 750-342 • 37
Starting up ETHERNET TCP/IP fieldbus nodes
Modular I/O System
ETHERNET TCP/IP
Note
The IP address can be allocated under other operating systems (i.e. under Li-
nux) as well as with any other BootP servers.
Attention
The IP address can be allocated in a direct connection via a crossover cable or
via a parallel cable and a hub. An allocation over a switch is not possible.
BootP table
Note
Prerequisite for the following steps is the correct installation of the WAGO
BootP server.
1.
Go to the Start menu, menu item Programs / WAGO Software / WAGO
BootP Server and click on WAGO BootP Server configuration.
An editable table will appear: "bootptab.txt".
This table displays the data basis for the BootP server. Directly following the
list of all notations used in the BootP table there are two examples for the
allocation of an IP address.
"Example of entry with no gateway" and "Example of entry with gate-
way".
