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.

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.

1-2 Overview of FLEX Integra and your Analog Modules
Types of FLEX Integra Modules We describe the following FLEX Integra Analog modules in this user
manual:
FLEX Integra analog input, output and combination modules are block
transfer modules that interface analog signals with any Allen-Bradley
programmable controllers that have block transfer capability. Block
transfer programming moves input from the module’s memory to a
designated area in the processor data table, and output data words from a
designated area in the processor data table to the module’s memory. Block
transfer programming also moves configuration words from the processor
data table to module memory.
The analog modules have selectable ranges as shown in the table below:
How FLEX Integra Analog
Modules Communicate with
Programmable Controllers
The adapter/power supply transfers data to the module (block transfer
write) and from the module (block transfer read) using BTW and BTR
instructions in your ladder diagram program. These instructions let the
adapter obtain input values and status from the module, and let you send
output values and establish the module’s mode of operation. Figure 1.1
describes the communication process.

The adapter transfers your configuration data
to the module using a BTW.
Your ladder program instructs the
adapter to perform a BTR of the values
and stores them in a data table.
The adapter and module determine
that the transfer was made without error
and input values are within specified
range.
Your ladder program can use and/or move the data
(if valid) before it is written over by the transfer of
new data in a subsequent transfer.
Your ladder program performs BTWs to the module when
you power it up, and any time you wish to reconfigure the module.
The module converts analog signals
into binary format and stores these
values until the adapter requests their
transfer.
External devices transmit
analog signals to the module.

How to Install Your Analog Module
Chapter Objectives In this chapter, we tell you about:
•how to install your module
•how to wire your module
•the indicators
Before You Install Your
Analog Module
Before installing your analog module in the I/O chassis:
Compliance to
European Union Directives
If this product has the CE mark it is approved for installation within the
European Union and EEA regions. It has been designed and tested to meet
the following directives.
EMC Directive
This product is tested to meet Council Directive 89/336/EEC
Electromagnetic Compatibility (EMC) and the following standards, in
whole or in part, documented in a technical construction file:
•EN 50081-2EMC – Generic Emission Standard, Part 2 – Industrial
Environment
•EN 50082-2EMC – Generic Immunity Standard, Part 2 – Industrial
Environment
This product is intended for use in an industrial environment.
You need to: As described under:
Calculate the power requirements of all
modules in each chassis.
Power Requirements, page 2-2

ATTENTION: +24V dc power must be applied to your
module before operation. If power is not applied, the module
position will appear to the adapter as an empty slot in your
chassis. If the adapter does not recognize your module after
installation is completed, cycle power to the adapter.

2-2 How to Install Your Analog Module
Low Voltage Directive
This product is tested to meet Council Directive 73/23/EEC Low Voltage,
by applying the safety requirements of EN 61131-2 Programmable
Controllers, Part 2 – Equipment Requirements and Tests.
For specific information required by EN 61131-2, see the appropriate
sections in this publication, as well as the following Allen-Bradley
publications:
•Industrial Automation Wiring and Grounding Guidelines For Noise
Immunity, publication 1770-4.1
•Guidelines for Handling Lithium Batteries, publication AG-5.4
•Automation Systems Catalog, publication B111
This equipment is classified as open equipment and must be mounted in an
enclosure during operation to provide safety protection.
Power Requirements The wiring of the module is determined by the current draw through the
terminals. Make certain that the current draw does not exceed 10A.
Installing the Module Installation of the analog module consists of:
This module mounts on a DIN rail. It connects to an adapter or another
FLEX I/O or Integra module. Note: If using this module with FLEX I/O
modules, do not mount between FLEX I/O modules. Mount Integra
modules to the right of the FLEX I/O modules. To mount this module::
1. Remove the cover plug (if used) in the male connector of the unit to
which you are connecting this module.

ATTENTION: Total current draw through the module
wiring terminals is limited to 10A. Separate power
connections may be necessary.

ATTENTION: Do not daisy chain power or ground from
an analog module to any ac or dc discrete module.

2. Position the module on the 35 x 7.5mm DIN rail A(A-B pt. no.
199-DR1). Rotate the module onto the DIN rail with the top of the rail
hooked under the lip on the rear of the module.
3. Press down to lock the module on the DIN rail.l
If the module does not lock in place, use a screwdriver of similar device
to move the locking tab down, press the module flush with the DIN rail
and release the locking tab to lock the module in place
4. Firmly push the module into the adjacent module/terminal base until the
units lock together.
5. Repeat the above steps to install the next Integra module.

2-4 How to Install Your Analog Module
6. To remove an Integra module, you must work from the right side and
remove one module at a time. To disengage a module from its neighbor,
place a common flat-bladed screwdriver between the 2 modules and turn
1/4 turn to separate the modules.
7. Then slide the module away from its left neighbor, and release the
locking lever to remove the module from the DIN rail.

ATTENTION: Do not remove this module under power.
Removing this module under power will break the electrical
backplane (flexbus) connections. This can cause personal injury
or property damage by:
•sending an erroneous signal to your system’s field devices
causing unintended machine motion
•causing an explosion in a hazardous environment
•breaking communication to modules beyond this module
