AS-Interface – Building Automation
The advantages of
AS-Interface – such as simple, cost-saving
installation and high degree of flexibility – have now become familiar
in Building Automation as well. Numerous companies are relying on the ASi
installation system for applications such as controlling fire and smoke damper
systems, shutter drives or heating and cooling ceilings using analog output
modules. Damper actuators with flow regulators can also be connected to the
controller through the MP-Bus Gateway. It is also possible to process EnOcean
signals from wireless buttons and sensors through ASi. Customer proximity is our
hallmark, which means we stand by you in word and deed and are open to
custom-tailored solutions. Just contact us.

To top

Basic Concept of AS-Interface
AS-Interface is an
industrial networking solution for automation systems. It is designed for
connecting simple field
I/O devices such as binary ON/OFF, analog and safety I/O devices according
to EN 50295, IEC 62023-2. Using only a two conductor flat or round cable (ASi
cable, 2 x 1.5 mm2, 16 AWG) to connect all slaves to the master using a free
topology. This is the main advantage of this system compared to conventional,
parallel wiring, where every single signal has to be wired directly to the
control system.

Data and power are available in the same
ASi cable . Every slave or module has its own address for accessing its
data. The slaves can be addressed from 1 to 31 (single slaves), or, with
extended addressing, there are 62 slaves available (1A to 31A and 1B to 31B).
Single slaves and modules with extended addressing (AB modules) can share the
same network.

To top

The Structure
The ASi
Master/Gateway controls the ASi network and acts as a direct link to the
host (PLC, Building Management Systems, etc.). Combined with an integrated
mini-PLC functionality the master can also be used for pre-processing or as a
stand-alone device without the need for a host controller (programming language
IL or C).

A Gateway is an ASi Master, and simultaneously a slave to higher level
network (
PROFIBUS ,
EtherNet/IP ,
Modbus , etc.). AS-Interface is the lowest level of the automation pyramid
intended for Actuator/Sensor networking.

Free Topology
ASi supports free topology such as Star, Ring, Linear,
Tree and Mesh network (see examples below).

Tree topology

Ring topology

To top

Network

(Click to enlarge)

The simple and highly flexible ASi network bus is one of the great strengths
of the system. The master/slave principle allows the use of any topology and
features a variety of different field and control cabinet modules. Whatever the
requirements in your building we make it possible to record both digital and
analog values and control either type of actuator. Whether a ventilation flap
with four digital and four analog outputs, an analog output module for
controlling heating/cooling ceilings, or special equipment such as an MP-Bus or
EnOcean gateways.

You can also process both ASi standard and ASi Safety
(up to SIL3) data over the same ASi network. The data can be processed in the
master or passed on to the higher level building management system through the
fieldbus interface on the master.

Benefits at a glance

Save hardware by reducing I/O cards, cabinets and wiring

Robust, globally standardized industrial bus with already more than 27
million installed nodes

Simple electronics with robust performance in industrial quality

Free choice of network topology

Quick installation, reduce maintenance and shorten testing time,fast
commisioning and ability to expand the system

Easy commissioning, and opportunity to expand the system

Transmission in real-time

Avoid wiring errors (no risk of faulty electrical connection)

High resistance against EMC noise

Fast error localization, spontaneous diagnostics and enhanced diagnostic
options

Compatibility
ASi is fully backwards compatible. This means that a
master according to the last specification 3.0 can communicate with all
existing
slaves according to the different specifications 2.0, 2.11 and 3.0. This
guarantees a future proof investment.

Simply to connect
Owing to the
yellow profile cable* and the piercing technology, ASi modules are easily
expandable and can be connected reverse polarity protected.

* Of course other cables, such as NYM-J or
E90 cable, can also be used.
