NOTE: If the user attempts to edit a configuration parameter when a Class 1
EtherNet/IP connection exists between an EtherNet/IP scanner and the E300
Electronic Overload Relay EtherNet/IP Communication Module, a message
similar to the one shown below will appear when the Apply button is pressed.
Automation Controller
Communications The E300 Electronic Overload Relay EtherNet/IP Communication Module
supports two types of EtherNet/IP messaging.
• I/O Messaging - Used for deterministic EtherNet/IP communications
with ControlLogix™, CompactLogix™, SoftLogix™, and EtherNet/IP
scanners. Its primary use is to read and write I/O data for control purposes.
• Explicit Messaging - Used for non-deterministic communications 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™ and Studio 5000™ software is used to configure I/O messaging
between an automation controller and the E300 Electronic Overload Relay
EtherNet/IP Communication Module on an EtherNet/IP network.
Shown below are two examples and the steps necessary to configure a Logix
controller for I/O messaging.
• Logix Configuration with Add-On Profile
• Logix Configuration with a Generic Profile
