3-2 Operation

ENI and ENIW Functional

Overview

The ENI and ENIW provide EtherNet/IP connectivity for RS-232

devices that use DF1 full-duplex protocol. DF1 full-duplex is an open,

point-to-point protocol used in any Allen-Bradley controller with an

RS-232 port, and in many other devices. DF1 full-duplex supports up

to 255 node addresses. The ENI and ENIW use these node addresses

for different functions.

The ENI and ENIW use a memory (node) map to provide access to

the different functions you can perform. Each function uses a different

group of node addresses. The following table illustrates the ENI and

ENIW functions by groups of node numbers:

General Ethernet

Information

Each Ethernet device requires a unique IP address. If your Ethernet

network is isolated from the company-wide network, any valid IP

address may be used. If your Ethernet hub is connected to a larger

Ethernet network, contact your System Administrator for unique IP

addresses.
