Important User Information

Publication 17946.5.5 - October 1996

Summary of Changes

This publication contains new and revised information not included

in the last release.

New Information

Additional Flex I/O Modules

The following modules have been added to this publication:

•8 Electronically Fused Output Module, cat. no. 1794-OB8EP

•10 Input/6 Output Module, cat. no. 1794-IB10XOB6

•SCANport Module, cat. no. 1203-FM1

Revised Information

All screens for selection and configuration of the Flex I/O adapter

and modules have been updated. New buttons have been added to the

screens for ease of movement between screens.

The “Set to Defaults” button has been changed to “Set to I/O Only.”

This applies the real time values for I/O (optimal settings) to the

module.

A “Memory” button has been added to the individual configuration

screen for each module. If you change your mind about any settings

you have made while you are on the configuration screen, clicking

on the “Memory” button returns you to the original settings.

The “Save to Flex I/O” no longer both saves and exits you. You must

click on the “Close” button to exit.

Change Bars

The areas in this manual which are different from previous editions

are marked with change bars (as shown to the right of this paragraph)

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.

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:
