Armor ControlLogix Controllers
Set the Network IP Address of the EtherNet/IP Modules
The EtherNet/IP communication modules reside in slots 2 and 3 of the ControlLogix chassis within the enclosure. The modules are shipped with
Bootstrap Protocol (BOOTP)/Dynamic Host Configuration Protocol (DHCP) enabled and their rotary switches set to 999. You can use the
following methods to set the IP address of each module.
• BOOTP/DHCP server
• RSLinx Classic software
• Studio 5000 Logix Designer® application
See the EtherNet/IP publications that are listed in
Additional Resources on page 16
for detailed information on setting an IP address.
Set the Network IP Address with the BOOTP/DHCP Server
The BOOTP/DHCP server is a standalone server that you can use to set an IP address. When used, the BOOTP/DHCP server sets an IP address
and other Transport Control Protocol (TCP) parameters.
Access the BOOTP/DHCP server from one of these locations:
• Programs > Rockwell Software > BOOTP-DHCP Server
If you have not installed the server, you can download and install it from
http://www.ab.com/networks/ethernet/bootp.html
.
• Tools directory on the Studio 5000® environment installation CD
Follow these steps to set the IP address of the module by using a BOOTP/DHCP server.
1. Start the BOOTP/DHCP software.
2. From the Tools menu, choose Network Settings.
3. Type the Subnet Mask of the network.
The Gateway address, Primary and/or Secondary DNS address, and Domain Name fields are optional.
4. Click OK.
The Request History panel shows the hardware addresses of all modules issuing BOOTP requests.
ATTENTION:
The EtherNet/IP communication module must be assigned a fixed network address. The IP address of this module must not be dynamically
provided. Failure to observe this precaution can result in unintended machine motion or loss of process control.
IMPORTANT
Before you start the BOOTP/DHCP server, make sure that you have the hardware (MAC) address of the module. The hardware address is on the label
on the bottom of the enclosure.
