EtherNet/IP Communications Module

Chapter 4, Configuring the Module, and chapter 5, Configuring the

Scanner or Bridge, discuss how to configure the module and

scanner or bridge 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 module and scanner or bridge.

6.2 Understanding the I/O Image

The terms input and output are defined from the scanner’s point of

view. Therefore, Output I/O is data that is output from the scanner

and consumed by the EtherNet/IP module. Input I/O is status data

that is produced by the module and consumed as input by the

scanner. The I/O image table will vary based on the following:

• Size (either 16-bit or 32-bit) of the Reference/Feedback words

and Datalink words used by the drive.

• Configuration of I/O (DPI I/O Config (23)). If all I/O is not enabled,

the image table is truncated. The image table always uses

consecutive words starting at word 0.
