Using Explicit Messaging
Chapter 6 provides information and examples that explain how to use
Explicit Messaging to configure and monitor the EtherNet/IP adapter
installed and connected to the PowerFlex 40 drive.
Refer to

for information about the I/O image, using Logic
Command/Status and Reference/Feedback.
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: Risk of equipment damage exists. 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.
