Using the Ethernet Interface
6-3
You must have two separate and unique addresses for the control-
coprocessor Ethernet port:
software configurable Internet Protocol (IP) address and host name that
you acquire from your network manager
hardware Ethernet address that is assigned to the control coprocessor by
Allen-Bradley at the factory—see the section on configuring the
Ethernet port to identify this address on page 6-11
Acquiring Your IP Address
If you are adding the control coprocessor to an existing network, contact
your network administrator to get an IP address. IP addresses must be
unique; each address is dependent on how your network is configured and
whether the local area network has a gateway to other networks.
Important: Do not make up your own IP address. Get the number from
your network administrator; your network administrator should have
acquired a set of numbers from InterNIC Registration Services. If you do
not have a network administrator, get your numbers from InterNIC
Registration Services.
You can get IP addresses by contacting InterNIC Registration Services via
electronic mail to
. If electronic mail is
not available to you, mail a hardcopy request to:

Acquiring a Host Name
Indicate your preference for a host name. Host names must be unique
within a domain. Host names must start with a letter and be only
alpha-numeric with dashes and/or underscores.
A host name consists of a word or other character string. The character
string usually consists of lower-case characters. The string is typically a
maximum of 8 characters. The full host name includes both the host name
and the domain name. For example:
Host name: maggie
Domain: “copro.ab.com”
Full host name: “maggie.copro.ab.com”
