Appendix

Module Addressing and Configuration with

MicroLogix 1500 Controller

Introduction

This appendix examines the modules’ addressing scheme and

describes module configuration using RSLogix 500 software and a

MicroLogix 1500 controller.

Module Input Image

The modules’ input image file represents data words and status bits.

Input words 0…15 hold the input data that represents the value of the

analog inputs for channels 0…15. These data words are valid only

when the channel is enabled and there are no errors. Input words

17…21 hold the status bits. To receive valid status information, the

channel must be enabled.

For example, to obtain the general status of channel 2 of the analog

module located in slot 3, use address I:3.17/2.
