Change the IP Address of a
Controller
94
You can change the IP address of a CompactLogix 5370 controller after system
operation has begun. In this case, the controller has an IP address that is assigned
to it, but you must change that IP address.
You can use these tools to change the IP address of a controller:
• RSLinx Classic software
• Studio 5000 Logix Designer® application
• SD card
You cannot use any of these tools to change a the IP address of a controller:
IMPORTANT
• Bootstrap Protocol (BOOTP) server
• Dynamic Host Configuration Protocol (DHCP) server
Consider these factors when you determine how to change the IP address of a
controller:
• Network isolation from, or integration into, the plant/enterprise network
• Network size - For large, isolated networks, it can be more convenient and
safer to use a BOOTP/DHCP server rather than
the Studio 5000 environment or RSLinx Classic software. A BOOTP/
DHCP server limits the possibility of duplicate IP address assignment.
However, you can only use the BOOTP/DHCP server to set the IP
address of the controller and not to change it. If you decide to change the
IP address of the controller and want to use a BOOTP/DHCP server to
limit the possibility of duplicate IP address assignment, you must first clear
the IP address.
After clearing the IP address, use the steps that are described at
BOOTP Server to Set the IP Address of the Controller on page 79
the DHCP Server to Set the IP Address of the Controller on page 86
set the IP address of the controller.
