6. Now select a desired IP address for your fieldbus node.
Attention
When selecting your IP address, ensure that it is in the same local network in
which your PC is located.
7. Please note the IP address you have chosen:

3.1.6.4 Allocating the IP Address to the Fieldbus Node
A prerequisite for communication with the controller is the assignment of an
IP address.
The address can be transferred through BootP or a PFC program.
With the PFC program, this is possible in WAGO-I/O-PRO CAA using the
fuction block "ETHERNET_Set_Network_Config" of the library
„Ethernet.lib“.
The address can be transferred through a BootP server or a PFC program. With
the PFC program, WAGO-I/O-PRO CAA is used to program the function
block "ETHERNET_SET_NETWORK_CONFIG" of the library
“Ethernet.lib“.
The following describes how to allocate the IP address for a fieldbus node
using the WAGO BootP server by way of an example. You can download a
free copy of the WAGO’s BootP server over the Internet under at
“http://www.wago.com”.
Note
The IP address can be allocated under other operating systems (e.g. under
Linux) 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.
