This manual shows you how to use your FLEX I/O pulse counter

module with Allen-Bradley programmable controllers. The manual

helps you install, program and troubleshoot your module.

You must be able to program and operate an Allen-Bradley

programmable controller to make efficient use of your FLEX I/O

module. In particular, you must know how to program block

transfers.

We assume that you know how to do this in this manual. If you do

not, refer to the appropriate programming and operations manual

before you attempt to program your modules.

In this manual, we refer to:

–the pulse counter module as the “input module”

–the Programmable Controller as the “controller”

This manual is divided into seven chapters. The following chart lists

each chapter with its corresponding title and a brief overview of the

topics covered in that chapter.

Chapter Title Contents

1Overview of FLEX I/O and the

Pulse Counter Module Describes FLEX I/O pulse counter modules, features, and

how they function

2How to Install Your Pulse Counter

Module How to install and wire the module

3Module Programming Explains block transfer programming, sample programs

4Writing Configuration to and

Reading Status From with a

Remote I/O Adapter

Explains how to configure your modules and read status

information from your modules when using a remote I/O

adapter

5How Communication Takes Place

and I/O Image Table Mapping

with the DeviceNet Adapter

Explains how you communicate with your modules, and

how the I/O image is mapped when using a DeviceNet

adapter

6Calibrating Your Pulse Counter

Module How to calibrate the module.

7Troubleshoot Your Pulse Counter

Module How to use the indicators to troubleshoot your module.
