Chapter 3 Configure the Adapter with RSLogix5000 software

Configuration

Requirements

Before you can use your adapter, you must configure its IP address, its subnet

mask, and, optionally, a gateway address. You can use the Rockwell BootP utility,

version 2.3 or later, to perform the

configuration. You can also use a DHCP

server or the network address switches to configure these parameters.

If you need to reset the adapter to factory defaults, see Work with the

Configuration Pages on page 96.

IP Address

The IP address identifies each node on the IP network (or system of connected

networks). Each TCP/IP node on a network (including the adapter) must have a

unique IP address.

The IP address is 32 bits long and has a Network ID part and Host ID part.

Networks are classified A, B, C, (or other). The class of the network determines

how an IP address is formatted

You can distinguish the class of the IP address from the first integer in its dotted-

decimal IP address as follows:

Each node on the same physical network must have an IP address of the same

class and must have the same network ID. Each node on the same network must

have a different Host ID thus giving it a unique IP address.

IP addresses are written as four decimal integers (0…255) separated by periods

where each integer gives the value of one byte of the IP address

ATTENTION: You must only use Series C and above POINT I/O modules

with 1734-AENTR EtherNet/IP Adapters. Series A or Series B POINT I/O

modules do not work with 1734-AENTR EtherNet/IP Adapters (does not

apply to POINTGuard modules).

EXAMPLE

For example, the 32-bit IP address:

10000000 00000001 00000000 00000001 is written as

128.1.0.1
