About the Module

The 12 Input/12 Output Discrete Embedded TTL I/O Module is a 24-point board with four pulse width modulation (PWM) outputs. Inputs and outputs are transistor-transistor logic (TTL) compatible. TTL indicates logic voltage levels from 0 to 5V dc (low voltage < 1V dc; high voltage > 2V dc).

The module uses DeviceLogix technology. DeviceLogix is a local logic capability that lets you control outputs and manage status information within the device.

The module communicates via a DeviceNet network.

2 12 Input/12 Output Discrete Embedded TTL I/O Module with Pulse Width Modulation and DeviceLogix

The module is equipped with AutoBaud detect, and is shipped with Autobaud enabled. AutoBaud lets the module detect the baud rate on your DeviceNet network and automatically adjusts the module to that rate.

Important User Information

Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://literature.rockwellautomation.com) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.

The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams.

No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software described in this manual.

Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell Automation, Inc., is prohibited.

Throughout this manual, when necessary, we use notes to make you aware of safety considerations.

ATTENTION

Environment and Enclosure

This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters without derating.

This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbance.

This equipment is supplied as open type equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications.

NOTE: See NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosure. Also, see the appropriate sections in this publication, as well as the Allen-Bradley publication 1770-4.1, Industrial Automation Wiring and Grounding Guidelines, for additional installation requirements pertaining to this equipment.

Install the Module

To install the module, you must do the following:

• Set the node address.

• Mount the module.

• Connect the module to the DeviceNet network and to your I/O.

• Communicate with the module.

• Configure module parameters.

• Configure DeviceLogix parameters.

ATTENTION

Prevent Electrostatic Discharge

This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment:

• Touch a grounded object to discharge potential static.

• Wear an approved grounding wriststrap.

• Do not touch connectors or pins on component boards.

• Do not touch circuit components inside the equipment.

• If available, use a static-safe workstation.

• When not in use, store the equipment in appropriate

static-safe packaging.

Set the Node Address

Set the node address using the rotary switches or a DeviceNet software configuration tool such as RSNetWorx for DeviceNet.

The two switches are S1 and S2:

Switch Label Function

S1 MSD - Most Significant Digit

S2 LSD - Least Significant Digit

Use the following illustration to help you locate the switches.

Publication 1799-IN008A-EN-P - July 2005

31572-M

6 12 Input/12 Output Discrete Embedded TTL I/O Module with Pulse Width Modulation and DeviceLogix

Valid node addresses are 00 through 63. Each board is shipped with the node address set to 63 in the board’s memory. The rotary switches are set for position 99 at shipment.

TIP

To set the node address, do the following:

1. Use a small blade screwdriver to rotate the switches.

2. Line up the small arrow on the switch with the number setting you wish to

use.

The rotary switches are read at board power-up only. Settings between 64 and 99 cause the board to use the last valid node address stored in the board’s memory.

Mount the Module

Use the following illustration to help you mount the module.

You can mount the board in an enclosure with pre-tapped holes.

Use the table on page 2 as a guide when purchasing mounting hardware.

Stand-off (1 of 6)

1. Place the six stand-offs behind the module.

2. Align the holes on the module with the stand-offs.

3. Place the screws through the module into the stand-offs and tighten.
