Introduction The E1 Plus EtherNet/IP Side Mount Module supports three types of EtherNet/
IP messaging:
• I/O Messaging — Used for deterministic Ethernet 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. Explicit messages have a lower
priority compared to I/O messages, and they are used to read and write
non-critical data. Logix controllers, MicroLogix 1100 and 1400 controllers
support Explicit Messaging using a MSG instruction.
• ControlLogix Style Tags — Used for non-deterministic communications
in which the data will is used in an HMI, SCADA, or historical data
logging software system. Software packages can read and write data
directly from the device.
This chapter describes and shows examples of how each type of messaging is used.
I/O Messaging RSLogix 5000™ software is used to configure I/O messaging between an
automation controller and an E1 Plus EtherNet/IP Side Mount Module on an
EtherNet/IP Network. This example will show the steps necessary to configure a
ControlLogix controller for this type of messaging.
ControlLogix Configuration with Add-On Profiles
Note: If you are not using Add-on
profiles, please turn to
page 38 .
If you have RSLogix 5000 v. 20.0, the E1 Plus add-on profile (AOP) is included.
Proceed with the following instructions. If you do have v. 19 or earlier, download
the AOP before proceeding.
An existing project can be used or a new project can be created to configure
EtherNet/IP I/O messaging. To create a new configuration in RSLogix 5000,
select File
