Overview
This document will allow a user to setup an Ethernet IP Tag Datalink between an
Omron CJ2 PLC and a Rockwell Control Logix 5561 PLC. This tag datalink will share
an array of 100 Channels (200 Bytes) from the Omron CJ2 PLC to the Rockwell PLC
and an array of 100 Integers (200 Bytes) from the Rockwell PLC to the Omron CJ2
PLC.
