Using the I/O
This chapter provides information and examples that explain how to control,
configure, and monitor an E3 Plus module by using the configured I/O.
About I/O Messaging On CIP-based networks, including EtherNet/IP network, I/O connections are
used to transfer the data that controls the E3 Plus module. I/O can also be used to
transfer data to and from E3 Plus modules.
Chapter 3 and Chapter 4 discuss how to configure the adapter and controller on
the network for these options. The Glossary defines the different options. This
chapter discusses how to use I/O after you have configured the adapter and
controller.
Understanding the I/O Image The terms input and output are defined from the controller’s point of view.
Therefore, output I/O is data that is produced by the controller and consumed by
the E3 Plus module. Input I/O is status data that is produced by the E3 Plus
module and consumed as input by the controller. The I/O image varies based on
the following:
• Configuration of the Input and Output Assemblies in the E3 Plus. For
more information on this, see E3 and E3 Plus Solid-State Overload Relay
User Manual, publication
193-UM002.
• ControlLogix/CompactLogix Controllers only —The E3 Plus module
profile used in RSLogix 5000 software (E3 Plus module Add-on Profile in
version 16 or later, Classic Profile in version 15, or Generic Profile in all
versions).
