4-12 ENI/ENIW Configuration (Nodes 241 to 254)

Controller Messaging

When using this method, a write message is used to configure the

TCP/IP configuration parameters. A 485CIF write message is initiated

to the controller. CIF stands for Common Interface File and is

supported by all Allen-Bradley programmable controllers that have an

RS-232 port.

The first item to configure is the ENI/ENIW’s IP address on your

network. See the following section, Configuring ENI/ENIW Data

Parameters, for that configuration procedure.

The configuration parameters are described in more detail beginning

on page 4-12.

ENI/ENIW Configuration

Parameters

The following table shows the functions that nodes 241 to 255

perform and their default values. Descriptions of each function can be

found following the table.

TIP

A 485CIF write may also be referred to as a PLC2

Unprotected Write.

IMPORTANT

The IP addresses in any of the examples in this

manual were arbitrarily assigned and should only be

used on an isolated Ethernet network. Contact your

system administrator for unique IP addresses if you

are connecting your Ethernet devices to your

employer’s Ethernet network.
