ABBAC 800M Controller Hardware Product Guide

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

Section 1 Overview

Introduction

AC 800M can be defined as a hardware platform consisting of individual hardware 

units. AC 800M hardware platform can be programmed to perform multiple 

functions, depending on the specific unit configuration and operating system 

selected.

The hardware units which form the AC 800M Controller are:

• Processor units (including base plates)

• Communication interfaces for different protocols (including base plates)

• Power supply units, providing various power output levels

• Battery back-up unit

• For High Integrity systems control applications with AC 800M HI, special 

module SM810/SM811, is needed

Once configured, the AC 800M hardware platform effectively becomes 

the AC 800M Controller.

Equipped with the specified Control Software, the AC 800M Controller can be used 

for all kinds of process and industrial automation applications. With Control 

Software, the controller can act either as a stand alone process controller or as a 

controller, performing local control tasks, in a control network consisting of many 

interconnected computers. 

The AC 800M Controller is delivered without firmware. To provide the controller 

with Control Software, it will first be necessary to load the firmware and create

the application separately by using the Control Builder interface.

The AC 800M Controller consists of a selection of units mounted on horizontal DIN 

rails, as shown in Figure 1 on page 18, which can, if required, be housed within 

an enclosure.

The majority of units consist of a base mounting plate and a removable cover, which 

are attached to each other by means of screws. The base plate, which is always 

mounted on the DIN rail, carries the majority of the connections to the processor, 

power supplies and communication interfaces, as well as to the external buses and 

systems

The processor unit used for the AC 800M HI Controller is physically identical to 

other AC 800M controllers, simplifying service and spares support and providing
