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.
