11.1.2.1

BootP (Bootstrap Protocol)

The "Bootstrap Protocol" (BootP) can be used to assign an IP address and other

parameters to the fieldbus coupler/controller in a TCP/IP network. Subnet masks

and gateways can also be transferred using this protocol. Protocol

communication is comprised of a client request from the fieldbus coupler or

controller and a server response from the PC.

A broadcast request is transmitted to Port 67 (BootP server) via the protocol that

contains the hardware address (MAC ID) for the fieldbus coupler or controller.

The BootP server then receives this message. The server contains a database in

which the MAC ID and IP addresses are assigned to one another. When a MAC

address is found a broadcast reply is transmitted via the network.

The fieldbus coupler/controller "listens" at the specified Port 68 for a response

from the BootP server. Incoming packets contain information such as the IP

address and the MAC address for the fieldbus coupler/controller. A fieldbus

coupler/controller recognizes by the MAC address that the message is intended

for that particular fieldbus coupler/controller and accepts the transmitted IP

address into its network.

IP addresses can be assigned via BootP under Windows and Linux!

You can use WAGO-BootP-Server to assign an IP address under the Windows

and Linux operating systems. You can also use any other BootP server besides

WAGO-BootP-Server. You can also use any other BootP server besides the

WAGO-BootP-Server.

More information about WAGO-BootP-Server

The process for assigning addresses using WAGO-BootP-Server is described in

detail in the section "Commissioning".

The fieldbus coupler/controller supports the following options in addition to the

default "IP address" option:
