Module Description

The 1747-AENTR Adapter enables CompactLogix™ and ControlLogix®

processors to control SLC™ I/O modules. It is primarily designed to enable

migration of existing SLC controlled systems to Logix-based systems.

The adapter mainly acts as a gateway between the SLC backplane and

EtherNet/IP and typically replaces an SLC controller in the 1746 rack. On

remote SLC racks, it replaces the 1747-ASB module or the ControlNet® adapters

1747-ACN15 and 1747-ACNR15.

Control of the backplane I/O is accomplished with a CompactLogix or

ControlLogix controller communicating through an EtherNet/IP router in the

Logix backplane, across EtherNet/IP, and into the 1747-AENTR gateway.

As a gateway between the SLC backplane and EtherNet/IP, the 1747-AENTR

module is a CIP™ server (for both Explicit Messaging and I/O) on the Ethernet

port, and an SLC host on the 1746 backplane.

Connections can be made to support www.abb-drive.com 1746 and 1747 analog, digital, and

specialty I/O modules installed in the backplane.

IMPORTANT Studio 5000 Logix Designer® application (previously RSLogix 5000®)

revision 21 and later, and firmware revision 2.001 and later supports:

• multiple chassis, with a maximum number of three chassis;

• a maximum of 30 SLC I/O modules;

• a maximum of 96 Class 1 connections;

• up to 8 Class 3 connections.

The 1747-AENTR in a Logix System

In this example, the I/O modules communicate with the controller through the

1747-AENTR adapter. The controller can produce and consume tags to the I/O.

Configuration of devices and the network is done through the personal

computer running the controller and configuration software.

Diagnostic Indicators The module has the following diagnostic indicators:

• Link 1 and Link 2 status indicator

• Module indicator

• 4-character status display

What the Adapter Does The 1747-AENTR EtherNet/IP adapter performs the following primary tasks:

• Control of real-time I/O data (also known as implicit messaging) – the

adapter serves as a bridge between I/O modules and the network

• Support of messaging data for configuration and programming

information (also known as explicit messaging)
