Configure the EtherNet/IP Communication Auxiliary Module Chapter 2
DNS Addressing
To further qualify a module’s address, use DNS addressing to specify a host
name for a module. This also includes specifying a domain name and DNS
servers. DNS addressing makes it possible to set up similar network structures
and IP address sequences under different domains.
DNS addressing is only necessary if you refer to the module by host name, such
as in path descriptions in MSG instructions.
To use DNS addressing, perform this procedure.
1. Assign a host name to the module.
2. Configure the module's parameters.
3. In addition to the IP address, subnet mask, and gateway address,
configure a host name for the module, domain name, and primary/
secondary DNS server addresses.

File Installation
Before the EtherNet/IP communication auxiliary module is configured to
communicate on an EtherNet/IP network, it must be registered to the software
that configures the network (for example, Rockwell Automation RSLinx
Classic and RSNetWorx for EtherNet/IP software). You register the module by
installing an EDS file. You can obtain the EDS file for the EtherNet/IP
communication auxiliary module from one of two locations:
• embedded in the module OR
• the Allen-Bradley EDS file download website.
Download the EDS File
Embedded in the Module
The EDS file for the EtherNet/IP communication auxiliary module is
embedded within the module. After the IP address for the module has been
configured, connect the module to same Ethernet network as a personal
computer. Using a web browser on the personal computer, you can download
the EDS file using a web browser by following these steps:
NOTE:
Contact the network administrator to have a host name assigned. Valid host names should
comply with IEC-1131-3.
TIP When using Firmware revision 3.000 and higher, see page 33 for instructions
on how to commission the EtherNet/IP communication auxiliary module and
enable use of the embedded web page.
