1 Introduction

This chapter provides an introduction to automation with Advant Controller 31 (AC31), from the

overall architecture to the operational rules of the 40 and 50 series basic units.

1.1 

General information on the AC31 system

The AC31 system comprises the 40, 50 and 90 series. This operating guide describes the 40

and 50 series. The AC31 system description (order number 1SAC 1316 99 R0201) contains

the documentation for the 90 series.

Due to high modularity, AC31 offers both beginners and experienced users access to automa-

tion applications with 14 to 1000 inputs and outputs.

From a compact machine with only a few automated functions to large installations spread

over hundreds of metres or even kilometres, AC31 can be adapted to meet your requirements.

It is therefore possible to implement distributed applications throughout a site, workshop or

machine where all the components (input/output units, basic unit) are close to the sen-

sors/actuators. The whole installation is connected by a single twisted pair via which all infor-

mation from the sensors is sent after processing by the basic unit to the actuators via the de-

centralized intelligent units. The following communication interfaces are available to extend the

AC31’s possibilities and to ensure integration with other automation systems: MODBUS

,

ASCII, ARCNET

, RCOM, AF100. Developments in this field are ongoing.

Many users throughout the world have implemented numerous applications such as:

Õ

 Machine control:

Manufacture of parquet flooring

 Assembly of electrical contactors

 Manufacture of ceramic products

 Metal pipe welding, etc.

Õ

 Controlling-commanding installations:

Wharf cranes

 Water treatment plants

 Ski lifts

 Wind power systems, etc.

Õ

 Systems management:

Energy management

 Climatic management

 Tunnel ventilation

 Alarm systems in hospital environments

 Greenhouse lighting and ventilation control, etc.
