Who Should Use This

Manual

Use this manual if you are responsible for designing, installing,

programming, or troubleshooting control systems that use

Allen-Bradley Small Logic controllers.

You should have a basic understanding of SLC 500 and MicroLogix

products and be able to interpret the ladder-logic instructions required

to control your application. If you do not, contact your local

Allen-Bradley representative for information on available training

courses before using this product.

Purpose of This Manual

This manual is a reference guide for the Advanced Interface Converter

(AIC+). This manual:

• gives you an overview of the AIC+ interface converter operation.

• explains the procedures to install and wire the AIC+ interface

converter.

4 Preface

Additional Resources

The following documents contain additional information regarding

Rockwell Automation products.

Description

The AIC+ advanced interface converter provides a communication

link between various networked devices. The AIC+ interface converter

is compatible with a variety of SLC and MicroLogix controllers and

peripherals.

Communication Port and Switch Locations

MicroLogix 1000, 1200, and 1500 controllers provide power to the

AIC+ interface converter via the RS-232 8-pin mini-DIN port’s cable.

However, if a MicroLogix controller is not connected to this port, a

24V dc power supply connected to the converter’s external power

terminals is required. The dc power-source selector switch needs to

be set for your particular configuration.

See Network Diagrams starting on page 21 for more details on how to

wire and configure the AIC+ interface converter.

6 Product Overview

The communication-rate selector switch is used to match the

communication rate filter of the AIC+ interface converter to the

network communication rate. This switch does not change the

network communication rate and is normally left in the AUTO

position. In high noise environments, the communication-rate selector

switch should be taken out of the AUTO mode and set to the same

communication rate as the network.

See Auto Transmit Delay on page 35 for more information on

communication rates.

Operation Modes

The AIC+ interface converter can be used in the following modes.

• Point-to-point isolator

• RS-232 to RS-485 isolator

• RS-232 to half-duplex user mode ASCII isolator

Communication is established using hardware handshaking or auto

transmit signals.

Device Compatibility

The AIC+ interface converter can be used to interconnect the

following devices.

• SLC 500, 5/01, 5/02, and 5/03 processors (channel 1)

• SLC 5/03, 5/04, and 5/05 processors (channel 0)

• MicroLogix controllers

• Logix controllers

• 1756-DH485 ControlLogix module

• Operator interface devices

• Personal computer serial ports (or any 9-pin DTE serial port)

• Modems

TIP

You cannot connect the 1761-HHP-B30 Hand-held Programmer

to the AIC+ advanced interface converter.
