About This User Manual

General

An y security measures described in this User Manual, for example, for user access, password security, network security, firewalls, virus protection, etc., represent possible steps that a user of an 800xA System may want to consider based on a risk assessment for a particular application and installation. This risk assessment, as well as the proper implementation, configuration, installation, operation, administration, and maintenance of all relevant security related equipment, software, and procedures, are the responsibility of the user of the 800xA System.

This book describes the hardware platform AC 800M. It also describes in detail how to install, configure, operate and perform the necessary maintenance on all equipment making up the AC 800M or AC 800M HI controllers.

Control Builder is used to configure and program the AC 800M controller, and is referred to in this manual as Control Builder. For information on the controller software, see controller software documentation.  For important information about late changes and work-arounds for known problems, refer to the Release Notes (see Released User Manuals and Release Notes on page 28).

Microsoft Windows conventions are normally used for the standard presentation of material when entering text, key sequences, prompts, messages, menu items, screen elements, etc.

Warning, Caution, Information, and Tip Icons

This publication includes Warning, Caution, and Information where appropriate to point out safety related or other important information. It also includes Tip to point out useful hints to the reader. The corresponding symbols should be interpreted as follows:

Electrical warning icon indicates the presence of a hazard which could result in electrical shock.

W arning icon indicates the presence of a hazard which could result in personal injury.

Caution icon indicates important information or warning related to the concept discussed in the text. It might indicate the presence of a hazard which could result in corruption of software or damage to equipment/property.

Information icon alerts the reader to pertinent facts and conditions

Tip icon indicates advice on, for example, how to design your project or how to use a certain function

Although Warning hazards are related to personal injury, and Caution hazards are associated with equipment or property damage, it should be understood that operation of damaged equipment could, under certain operational conditions, result in degraded process performance leading to personal injury or death. Therefore, fully comply with all Warning and Caution notices.

Terminology

A complete and comprehensive list of terms is included in System 800xA System Guide Functional Description (3BSE038018*). The listing includes terms and definitions that apply to the 800xA System where the usage is different from commonly accepted industry standard definitions and definitions given in standard dictionaries such as Webster’s Dictionary of Computer Terms.

Introduction

Product Overview

AC 800M – General

AC 800M is a hardware platform comprising individual hardware units, which can be configured and programmed to perform multiple functions.

Once configured and programmed, the AC 800M effectively becomes the AC 800M or AC 800M HI controller.

The hardware units that form the AC 800M and AC 800M HI Controllers are:

• Processor units (including baseplate) (PM851/PM851A/PM856/PM856A/PM860/PM860A/PM861/PM861A/ PM864/PM864A/PM865/PM866/PM891) 

 • High Integrity Processor Unit (consists of PM865 and SM810/SM811 with corresponding baseplates) 

 • Communication interfaces for different protocols (including baseplates) (CI851/CI852/CI853/CI854/CI854A/CI855/CI856/CI857/CI858/CI860/ CI862/CI865/CI867/CI868/CI869/CI871/CI872/CI873) 

 • CEX-Bus Interconnection Unit (BC810) 

 • Power supply units, providing various power output levels SD831/SD832/SD833/SD834/SS823/SS832) 

 • Battery back-up unit (SB821/SB822) The SB821 is not supported with PM891.

PM851 is equivalent with PM856 unless stated otherwise. 

 PM851A is equivalent with PM851 unless stated otherwise. 

 PM856A is equivalent with PM856 unless stated otherwise. 

 PM860A is equivalent with PM860 unless stated otherwise 

 PM861A is equivalent to PM861 unless stated otherwise. 

 PM864A is equivalent to PM864 unless stated otherwise.

When equipped with the specified Control Software, the AC 800M Controller acts either as a stand-alone process controller, or as a controller performing local control tasks in a control network consisting of many interconnected controllers, operator stations and servers.

Various I/O systems can be connected to the AC 800M Controller, either directly (S800 I/O) or via PROFIBUS DP or FOUNDATION Fieldbus.

The AC 800M is delivered without Control Software. To provide the controller with Control Software, first load the firmware and then create the application separately using the Control Builder M engineering tool.

The AC 800M Controller consists of a selection of units mounted on horizontal DIN-rails, which can be housed within an enclosure. The majority of units consist of a base mounting plate and removable cover attached with screws.

The baseplate, which is always mounted onto the DIN-rail, carries the majority of the connections to processor, power supplies and communication interfaces, as well as the connections to the external buses and systems.

The AC 800M Controller provides a cost-effective, low-maintenance solution for applications ranging from small Programmable Logic Controller (PLC) to advanced Distributed Control Systems (DCS) control applications and combined DCS, and High Integrity systems control applications.

In the AC 800M High Integrity Controller, it is possible to run both non-SIL and SIL classified applications. The AC 800M HI consist of PM865, SM810/SM811 and a High Integrity version of Control Software, and is also available in redundant configuration. AC 800M HI requires the use of SIL certified S800 I/O units in SIL classified applications. If the application is not SIL classified, standard S800 I/O units can be used with AC 800M HI controller.
