Chapter 6
Using Explicit Messaging
This chapter provides information and examples that explain how to use Explicit
Messaging with a ControlLogix controller to configure and monitor the adapter
and connected PowerFlex 755 drive.
For information on using a PLC-5, SLC 500, or MicroLogix 1100/1400
controller, see Controller Examples for EtherNet/IP Network Communications
with PowerFlex 750-Series Drives, publication 750COM-AT001
.
See Chapter 5 for information about the I/O Image, using Logic Command/
Status, Reference/Feedback, and Datalinks.

ATTENTION: Risk of injury or equipment damage exists. 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.
ATTENTION: Risk of equipment damage exists. If Explicit Messages are
programmed to write parameter data to Nonvolatile 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.
