Configuring the Interface Module for Ethernet Communication 3-5
2. Make one copy of the Ethernet device template for every PLC-5
Ethernet Interface Module in your system (i.e. one line
per module).
3. Edit each copy of the template as follows:
A. Replace sidecar with the name you assigned the Ethernet
interface module. Use only letters and numbers; do not use
underscores.
B.Replace aa.bb.cc.dd with the IP address to be assigned to the
interface module.
C.Replace xxyy with the last four digits of the Ethernet hardware
address. Use only valid hexadecimal digits (0–9, A–F); do not
use the hyphens or colons that separate the numbers. (You will
find the hardware address on a label affixed to the printed
circuit board of the Ethernet interface module.)
4. Save, close, and make a backup copy of this file.
Example
In this example there are three PLC-5 processors (two enhanced
processors and one Ethernet processor) with attached 1785–ENET
interface modules and an HP 9000 workstation. The names and
hardware addresses are device specific:
The term “sidecar” in this template is a logical
name used for identification in this file only. It is not
associated with the stored processor name.
