5 - 16 EA3600 Network Connect Product Reference Guide

Sample Application for Logix Studio 5000 v24 With AOP

The EtherNet/IP sample application and scanner routine are located in the Industrial Ethernet Developer zip file

(CAAEAS00-001-RXXD0.ZIP).

A single example project, EA3600Sample_AOP_v2.zip, for Logix Studio 5000 v24 is available that uses the

ScannerRoutine to interface with the EA3600. This ScannerRoutine is also available as a separate archive

(ScannerRoutine_AOP_v2.L5X ).

EA3600Sample Barcode Transfer Example Logic

Using the Barcode Transfer Logic

The barcode transfer logic included in the example program is encapsulated in a separate routine called

ScannerRoutine. This allows the

barcode interface to be added easily to any program by simply adding the routine

and then jumping to it via the MainProgram. The ScannerRoutine adds a number of Local Tags that provide the interface

for the EA3600 I/O.

ScannerRoutine

The ScannerRoutine Local tags provide an input/output abstraction layer that simplifies interaction with the

EA3600 I/O. The tags are described in this section.
