Setting the IP Address
To configure the controller, define the IP address, subnet mask, and gateway.
You can configure your controller via two options; configuring through RSLinx
Classic software or through a BOOTP utility. Refer to page 51 for using
BOOTP or to page 54 for using RSLinx software.
Using BOOTP to Set the IP Address
BOOTP (bootstrap protocol) is a low-level protocol that TCP/IP nodes use to
obtain start-up information. An IP address is not set until a BOOTP reply has
been received. BOOTP lets you dynamically assign IP addresses to processors on
the Ethernet link.
To use BOOTP, a BOOTP server must exist on the local Ethernet subnet. The
server is a computer that has BOOTP server software installed and reads a text
file containing network information for individual nodes on the network.
The host system’s BOOTP configuration file must be updated to service requests
from the SmartGuard controller. In the default state (out of the box), the
SmartGuard controller requires the use of a BOOTP server to set its IP address.
Refer to Setting the IP Address for the parameters that need to be configured.
When BOOTP is enabled, the following events occur at power up:

Description
IP Address
The IP address uniquely identifies the controller. The IP address is in the form
xxx.xxx.xxx.xxx. where each xxx is a number between 0 and 255. The following reserved
values cannot be used:
·127.0.0.1
·0.0.0.0
·255.255.255.255
Subnet Mask
Subnet addressing is an extension of the IP address scheme that allows a site to use a single
network ID for multiple physical networks. Routing outside of the site continues by
dividing the IP address into a net ID and a host ID via the class. Inside a site, the subnet
mask is used to redivide the IP address into a custom network ID portion and host ID
portion. This field is set to 0.0.0.0 by default.
If you change the subnet mask of an already-configured controller, you must cycle power
for the change to take effect.
Gateway
A gateway connects individual physical networks into a system of networks. When a node
needs to communicate with a node on another network, a gateway transfers the data
between the two networks. This field is set to 0.0.0.0 by default.
TIP
You can use any commercially-available BOOTP server. If you do not have
BOOTP server capabilities on your network, and you want to dynamically
configure the SmartGuard controller, you can download the free Rockwell
