Chapter 3 Complete the Controller Setup
You can complete one of these tasks dependent on system conditions:
• Set the IP address for a controller that does not have one assigned.
• Change the IP address for a controller that has an IP address that is
assigned to it.
You must set the IP address of a Compact GuardLogix 5370 controller when
the controller powers up for the first time, that is, when commissioning the
controller for the first time. You are not required to set an IP address each time
that power is cycled to the controller.
You can use these tools to set the IP address of a Compact GuardLogix 5370
controller:
• Bootstrap Protocol (BOOTP) server
• Dynamic Host Configuration Protocol (DHCP) server
• RSLinx Classic software
• Logix Designer application
•SD card
Use the BOOTP Server to Set the lP Address
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 Compact
GuardLogix 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.
• The 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.
IMPORTANT Compact GuardLogix 5370 controllers have two EtherNet/IP ports to
connect to an EtherNet/IP network; you cannot install any additional
ports to these controllers.
The EtherNet/IP ports carry the same network traffic as part of the
embedded switch of the controller. However, the controllers use only
one IP address.
