Introduction

This document has been revised since the June 1996 printing.

Changes to this document are so extensive, that it is impractical to

mark every change with a revision bar in the margin of the page. The

purpose of this section is to outline the changes in the SCADA

Application Guide.

Scope of Changes

This SCADA Application Guide represents the latest developments

in Allen-Bradley hardware and software, and includes the most recent

third-party supplier information as it relates to SCADA applications.

Changes incorporated in this document include:

• The updating of the enhanced PLC-5 chapter (Chapter 2),

including new screen captures from RSLogix 5 and messaging

details.

• The restructuring of the SLC 5/03, 5/04 chapter (Chapter 4) to

include the SLC 5/05, new screen captures from RSLogix 500

and messaging details.

• The addition of a MicroLogix chapter, (Chapter 6) which details

the use of MicroLogix controllers in SCADA applications.

• The addition of a Logix5550 chapter, (Chapter 7) which details

the use of the Logix5550 controller in SCADA applications.

• Updated third-party modem documentation (Chapter 8).

• The addition of a RSLinx chapter, which details the configuration

of the RSLinx DF1 Polling Master and DF1 Slave drivers for use

in SCADA applications.

• The addition of an appendix (Appendix E) which provides

detailed examples of messaging ladder logic that is typical to

SCADA applications.
