General information on the AC31 system

Advant Controller AC 31 / Issued: 01.99
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.
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:
Machine control:
Manufacture of parquet flooring
Assembly of electrical contactors
Manufacture of ceramic products
Metal pipe welding, etc.
Controlling-commanding installations:
Wharf cranes
Water treatment plants
Ski lifts
Wind power systems, etc.
Systems management:
Energy management
Climatic management
Tunnel ventilation
Alarm systems in hospital environments
Greenhouse lighting and ventilation control, etc.
