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.

Note: If you are not using Add-on profiles, please turn to

page 38 .

ControlLogix Configuration with Add-On Profiles

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

→ New.

Three tags, "E1Plus:C", "E1Plus:I" and "E1Plus:O", have been added to represent the three I/O Instances: Configuration, input and output. The

Configuration Instance was created even though its size was configured as zero. The E1Plus:I tag represents input data, which is data coming from the E1Plus into the controller (%FLA, %TCU, Trip Status, Warning

Status, etc.). The E1 Plus:O tag represents output data, which is data going from the controller out to the E1 Plus (Enable Output A, Trip Reset, etc.).
