EtherNet/IP Explicit Messaging to CompactLogix / ControlLogix PLC

The document attached is a setup guide which applies to the EtherNet/IP option for the DX100, DX200, YRC1000 or YRC1000micro.  The guide is intended to help document the setup and project configuration to use the MSG (message) instruction in RSLogix 5000 or Studio 5000 when commissioning a modern Rockwell / Allen-Bradley PLC - CompactLogix or ControlLogix series to communicate with one of the robot controller models listed above.

A project file and guide are attached to this article.

Note:  EtherNet/IP Messaging can not be used when EtherNet/IP Safe is enabled!
