Chapter 3 Configure an EtherNet/IP Communication Module to Operate on the Network
Set the Network IP Address with RSLinx Software or the Studio 5000
Environment
This table describes when to set the network IP address with RSLinx software or
the Studio 5000 environment.
Consider these factors when you determine how to set the network IP address:
• Network isolation from or integration into the plant/enterprise network
• Network size - For large networks, isolated networks, it might be more
convenient and safer to use a BOOTP/DHCP server rather than the
Studio 5000 Environment or RSLinx software. The BOOTP/DHCP
server also limits the possibility of assigning duplicate IP addresses.
• Company policies and procedures dealing with plant floor network
installation and maintenance
• Level of involvement by IT personnel in plant-floor network installation
and maintenance
• Type of training offered to control engineers and maintenance personnel
If you use the Rockwell Automation BOOTP or DHCP server in an uplinked
subnet where an enterprise DHCP server exists, a module may get an address
from the enterprise server before the Rockwell Automation utility even sees the
module. You might have to disconnect from the uplink to set the address and
configure the module to retain its static address before reconnecting to
the uplink. This is not a problem if you have node names configured in the
module and leave DHCP enabled.
