NOTE: If you attempt to edit a configuration parameter when a Class 1
EtherNet/IP connection exists between an EtherNet/IP scanner and the E300
relay EtherNet/IP Communication Module, a message similar to the one shown
below appears when the Apply button is pressed.
Automation Controller
Communication
The E300 relay EtherNet/IP Communication Module supports two types of
EtherNet/IP messaging.
• I/O Messaging - Used for deterministic EtherNet/IP communication with
ControlLogix, CompactLogix, SoftLogix, and EtherNet/IP scanners. Its
primary use is to read and write I/O data for control purposes. It can also
be used for Automatic Device Configuration, in which an automation
controller manages device configuration parameters.
• Expl
icit Messaging - Used for non-deterministic communication in which
the
data is not critical for control. Logic explicit messages have a lower
priority compared to I/O messages and are used to read and write non-
critical data.
I/O Messaging
RSLogix 5000 or Studio 5000 software is used to configure I/O messaging
between a Logix controller and an E300 relay EtherNet/IP Communication
Module on an EtherNet/IP network. An Add-on Profile is available for the E300
relay EtherNet/ IP Communication Module and can be used with RSLogix 5000
version 16 and higher and Studio 5000 version 21 and higher. The E300 Add-on
Profile provides a graphical user interface to modify configuration parameters, it
provides intuitive input and output tag names, and it enables Automation Device
Configuration. You can download the E300 Add-on Profile from: http://

Automatic Device Configuration enables the Logix controller to manage device
configuration data. Every time a Logix controller establishes a connection with a
device, the Logix controller downloads that device’s configuration data. This
