Using Explicit Messaging
Chapter 7 provides information and examples that explain how to
use Explicit Messaging to configure and monitor a Reliance Electric
drive and an EtherNet/IP module.
Refer to chapter 6 for information about the I/O Image, using Logic
Command/Status, Reference/Feedback, and Datalinks.
7.1 About Explicit Messaging
Explicit Messaging is used to transfer data that does not require
continuous updates. With Explicit Messaging, you can configure
and monitor a slave device’s parameters on the EtherNet/IP
network.

ATTENTION: The examples in this publication are intended
solely for purposes of example. There are many variables and
requirements with any application. Rockwell Automation does
not assume responsibility or liability (to include intellectual
property liability) for actual use of the examples shown in this
publication. Failure to observe this precaution could result in
bodily injury and/or damage to equipment.
ATTENTION: If Explicit Messages are programmed to write
parameter data to Non-Volatile Storage (NVS) frequently, the
NVS will quickly exceed its life cycle and cause the drive to
malfunction. Do not create a program that frequently uses
Explicit Messages to write parameter data to NVS. Datalinks
do not write to NVS and should be used for frequently changed
parameters. Failure to observe this precaution could result in
bodily injury and/or damage to equipment.
