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.

How FLEX Integra Analog Modules Communicate with Programmable Controllers

The analog modules have selectable ranges as shown in the table below:

Voltage Current

0 to 10V dc 0 to 20mA

±10V dc 4 to 20mA

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.

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.

External devices transmit analog signals to the module.

Allen-Bradley

The module converts analog signals into binary format and stores these values until the adapter requests their transfer.

Your ladder program performs BTWs to the module when you power it up, and any time you wish to reconfigure the module.

How to Install Your Analog Module

Chapter Objectives

Before You Install Your Analog Module

In this chapter, we tell you about:

• how to install your module

• how to wire your module

• the indicators

Before installing your analog module in the I/O chassis:

You n e e d to: As described under:

Calculate the power requirements of all modules in each chassis.

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.

Power Requirements

Installing the Module

The wiring of the module is determined by the current draw through the terminals. Make certain that the current draw does not exceed 10A.

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.

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.

Chapter Objectives

Block Transfer Programming

In this chapter, we tell you about:

• analog data format

• block transfer programming

• sample programs for the PLC-3 and PLC-5 processors

Your module communicates with the processor through bidirectional block transfers. This is the sequential operation of both read and write block transfer instructions.

A configuration block transfer write (BTW) is initiated when the analog module is first powered up, and subsequently only when the programmer wants to enable or disable features of the module. The configuration BTW sets the bits which enable the programmable features of the module, such as scaling, alarms, ranges, etc. Block transfer reads are performed to retrieve information from the module.

Block transfer read (BTR) programming moves status and data from the module to the processor’s data table. The processor user program initiates the request to transfer data from the module to the processor. The transferred words contain module status, channel status and input data from the module.

ATTENTION: If the analog module is not powered up before the remote I/O adapter, the adapter will not recognize the module. Make certain that the analog module is installed and powered before or simultaneously with the remote I/O adapter. If the adapter does not establish communication with the module, cycle power to the adapter.

The following sample programs are minimum programs; all rungs and conditioning must be included in your application program. You can disable BTRs, or add interlocks to prevent writes if desired. Do not eliminate any storage bits or interlocks included in the sample programs. If interlocks are removed, the program may not work properly.

Your program should monitor status bits, block transfer read and block transfer write activity.
