Use a DHCP/BOOTP Server
If you do not have a large computer that can act as a boot server, download
our DHCP/BOOTP software so you can use a personal computer as a
DHCP/BOOTP server.
To set the network address by using the Rockwell Automation
DHCP/BOOTP server, follow these steps.
1. Access the DHCP/BOOTP utility at
http://www.ab.com/networks/ethernet/bootp.html .
2. Download the version 2.3.2 DHCP/BOOTP utility.
3. Extract the zipped files to a temporary directory.
4. In the temporary directory, double-click setup.exe to install the
DHCP/BOOTP utility.
5. Run the utility.
6. Refer to the following chart, which describes what happens next,
depending on whether DHCP/BOOTP is enabled on the module.
If DHCP/BOOTP is The module
Enabled Asks for an address from a DHCP/BOOTP server. The server
also assigns other Transport Control Protocol (TCP) parameters.
Not enabled Uses the IP address (along with other TCP configurable
parameters) stored in nonvolatile memory.
