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.
