SLC 500 EtherNet/IP Adapter 7

Publication 1747-IN521B-EN-E - January 2013

Diagnostic Indicators

Health indicators are located on the front panel of the adapter module. They indicate both
normal operation and error conditions in your remote I/O system.

An alphanumeric display (net address/status) provides status code indications when an error
occurs during initialization or operation.

A complete description of the diagnostic indicators and status display and how to use them for
troubleshooting is explained on page 11.

Understand Messaging

Class 3 (Explicit Message) requests through the 1747-AENTR adapter to a specific I/O module
may not always receive a response from the I/O modules. In the case where the I/O module does
not reply to the request, the adapter responds with an error code indicating a time-out.

Establish I/O Connections

When you start a system and establish I/O connections, the outputs transition to the Idle state,
applying Idle state data before going to Run mode. This occurs even when the controller making
the connection is already in Run mode.
