Preface
Using This Manual
Purpose of this Manual This manual shows you how to use your FLEX Integra Analog modules
with Allen-Bradley programmable controllers. The manual helps you
install, program and troubleshoot your modules.
Audience You must be able to program and operate an Allen-Bradley programmable
controller to make efficient use of your FLEX Integra modules. In
particular, you must know how to program block transfers, and be familiar
with DeviceNet or ControlNet software.
Vocabulary 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 analog input or analog output module as the “input module” or
“output module”
– the Programmable Controller as the “controller”
Manual Organization This manual is divided into five 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 Integra and
Analog modules
Describes FLEX Integra Analog modules, features, and how
they function
2How to Install Your Analog Module How to install and wire the modules
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
6Input, Status, Output and
Configuration with ControlNet
Explains how you communicate with your modules, and
how the I/O image is mapped when using ControlNet.

Chapter 1
Overview of FLEX Integra and your
Analog Modules
Chapter Objectives In this chapter, we tell you about:
• what the FLEX Integra system is and what it contains
• types of FLEX Integra analog modules
• how FLEX Integra analog modules communicate with programmable
controllers
• the features of your analog modules
The FLEX Integra System FLEX Integra is a small, modular I/O system for distributed applications
that performs all of the functions of rack-based I/O. The FLEX Integra
system contains the following components shown below:
• adapter/power supply – powers the internal logic for as many as eight
I/O modules
• I/O module with integral wiring terminals– contains the bus interface
and circuitry needed to perform specific functions related to your
application and connection terminals for connecting wiring.
