Chapter 5 EtherNet/IP Interface
Introduction
This chapter provides information about I/O assemblies, I/O connections, steps to configure Rockwell Automation
ControlLogix communication, and transferring barcode data from the EA3600.
Communications Profile
The EtherNet/IP interface on the EA3600 supports CIP Adapter functionality. The device is able to receive, or be
the target of, I/O connections from a CIP Scanner, but is not able to originate connections itself.
The interface supports the Generic device profile. The Generic profile provides for all CIP objects that are required
by the EtherNet/IP specification.
EDS File
The EtherNet/IP EDS file describes the Identity and I/O capabilities of the EA3600. The file is used by PLC
configuration tools to configure the I/O connections and data tags used to communicate with the EA3600 over the
EtherNet/IP network.
The latest EDS file can be acquired in the Industrial Ethernet Software Package. See Chapter 1, Initial Setup.
IMPORTANT Read Chapter 2, Ethernet Interface and Chapter 3, Barcode Transfer prior to this chapter. These
chapters provide information about EA3600 behavior that spans all protocols.
IMPORTANT By default, the EA3600 Requested Packet Interval is set to 100 ms. The configurable range of RPI
values is 10 ms to 1000 ms. Ladder logic operations that occur quicker than the RPI may result in lost
transitions, therefore it is important that timers be used to indicate transitions to the EA3600. For
example, if ladder logic toggles the SendAction bit with a pulse of 1 ms, the EA3600 may miss the
rising edge and no action is taken.
