Chapter 4
Use the BOOTP Server to Set the IP Address of the Controller
Bootstrap Protocol (BOOTP) is a protocol that enables the controller to
communicate with a BOOTP server. The server can be used to assign an IP
address. You can use the BOOTP server to set an IP address for your
CompactLogix 5370 controller.
Consider these points when using the BOOTP server:
•
The BOOTP server is installed automatically when you install RSLinx
Classic or the Studio 5000 environment on your computer. The BOOTP
server sets an IP address and other Transmission Control Protocol (TCP)
parameters.
•
A CompactLogix 5370 controller ships from the factory without an IP
address and BOOTP-enabled.
•
This section describes how to use a Rockwell Automation® BOOTP/
DHCP server. If you use another BOOTP/DHCP server, contact your
network administrator to verify that you are using it correctly.
•
To use the BOOTP server, your computer and the controller must be
connected to the same EtherNet/IP network.
•
If the controller is BOOTP-disabled, you cannot use the BOOTP server
to set the IP address.
There are two conditions in which the CompactLogix 5370 controllers use the
BOOTP servers to set the IP address of the controller:
• Initial powerup
- Because the CompactLogix 5370 controller ships with
BOOTP-enabled, when it is first powered up, the controller sends a
request for an IP address on the EtherNet/IP network. You can use the
BOOTP server to set the IP address, as described later in this section.
• Powerup after controller operation has begun
- When controller power
is cycled after operation has begun, the BOOTP/DHCP server sets the IP
address if one of these conditions exists:
–
Controller is BOOTP-enabled - You set the IP address manually with
the BOOTP server.
–
Controller is DHCP-enabled - The IP address is set automatically via
the DHCP server.
