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.

Environment and Enclosure

ATTENTION 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 m (6561 ft) 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 enclosure must have suitable

flame-retardant properties to prevent or minimize the spread of flame,

complying with a flame spread rating of 5VA, V2, V1, V0 (or

equivalent) if non-metallic. 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.

In addition to this publication, see:

•Industrial Automation Wiring and Grounding Guidelines, for additional

installation requirements, Allen-Bradley publication 1770-4.1.

•NEMA Standards publication 250 and IEC publication 60529, as

applicable, for explanations of the degrees of protection provided by

different types of enclosure.

WARNING AVERTISSEMENT

Process Remote I/O (RIO) Communication Interface Module 5

Publication 1757-IN916C-EN-P - March 2008

Prevent Electrostatic Discharge

Identify Module Features

ATTENTION 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.

•Use a static-safe workstation, if available.

•Store the equipment in appropriate static-safe packaging when

not in use.

The module has:

•a 4-character scrolling display.

•3 status indicators.

RIO indicates the status of the

network.

SYS indicates the connection to the

processor.

OK indicates the module’s own

internal state.

•a 3-pin Phoenix connector that

connects to the remote devices.

Prepare the Chassis for Module Installation

Before you install the 1757-ABRIO module, you must install and connect a

ProcessLogix or ControlLogix chassis and power supply.

Determine Module Slot Location

Chassis slots are numbered starting from the left, starting at 0. Slot 0 is the

first slot to the right of the power supply.

You can:

•use any size chassis.

•install the module in any available slot.

•install multiple 1757-ABRIO modules in the same chassis, depending

on how your power supply is rated.

Remove and Insertion Under Power

You can install or remove the module while the chassis is powered if you

observe these precautions.

WARNING When you insert or removethe module while backplane poweris on,

an electrical arc can occur. If you connect or disconnect the

communications cable with power applied to this module or any

device on the network, an electrical arc can occur. This could cause

an explosion in hazardous location installations.

Be sure that power is removed or the area is nonhazardous before

proceeding.

Repeated electrical arcing causes excessive wear to contacts on

both the module and its mating connector. Worn contacts may create

electrical resistance that can affect module operation.

Process Remote I/O (RIO) Communication Interface Module 7

Publication 1757-IN916C-EN-P - March 2008

Install the Module

To install the module, follow these steps.

1. Align the module circuit board with the top and bottom guides in the

chassis.

2. Slide the module into the chassis in the appropriate slot.

Make sure the module properly connects to the chassis backplane.

The module is fully installed when it is flush with the other installed

modules, and the module locking clips click into place.

3. To remove the module, push down on the locking clips at the top and

bottom of each module.

4. Slide the module out of the chassis.

ATTENTION Do not force the module into the backplane connector. If you cannot

seat the module with firm pressure, check the alignment. Forcing the

module into the chassis can damage the backplane connector or the

module.

Wire the Connector for the Remote I/O Network

Follow these steps to wire the connector.

1. Connect Line 1 of the remote I/O cable to the upper pin.

2. Connect the shield to the middle pin.

3. Connect Line 2 to the lower pin on the 1757-ABRIO.

4. Terminate both ends of a remote I/O network by using external

resistors attached to the physical ends of the network.

There should be two and terminators on the network.

Select Proper Resistor

Use 82 ohm resistors if the network operates at 230.4 kbps or if the network

operates at 57.6 kbps or 115.2 kbps and none of the devices in the table below

are present. The maximum number of devices on the network is 32.

Use 150 ohm resistors if the network contains any of the devices in the table

below, or if the network operates at 57.6 kbps or 115.2 kbps and you do not

require the network to support more than 16 devices.

Removing or Replacing the Module

If you are replacing an existing module with an identical one, and you want to

resume identical system operation, you must:

•install the new module in the same slot.

•run the configuration program and download the appropriate

configuration to the module.

Apply Chassis Power

Turn the rack power supply on.

Check Power Supply and Module Status

The rack power supply indicator should be green. The module OK status

indicator should be solid red immediately after you turn on the rack power

supply and then it turns solid green. Refer to the installation instructions for

your particular 1756 rack power supply for recommended actions for

checking your power supply.

Status Display Power-up Messages

The alphanumeric display shows the following messages at power-up.

If the indicator on the 1757-ABRIO module does not cycle through these

messages on powerup, refer to the Troubleshooting section of publication

1757-UM007C, the 1757-ABRIO User Manual.
