FOCUS ON THE
ESSENTIALS - AUTOMATING WITH AS-INTERFACE
The history of automation basically starts at
the same time as the history of the industrial revolution. As soon
as James Watt got the Newcomen's steam engine to work, he started
thinking about optimizing its control system. The question: How can
I operate a steam engine independent of load with a constant and
consistent number of revolutions? The solution was a centrifugal
governor. From then on, the workers on the machine could
concentrate on production. Regulating the number of revolutions per
minute was automated.
Up until the 1960s, automation systems were
marked by mechanic solutions. Computers did not exist yet, logical
links between machine and system were hard-wired with relay
contacts. The introduction of process computers and programmable
logic operation controllers made it possible to react in a flexible
manner to the numerous requests for automation systems. System
solutions increased explosively and today, a multitude of options
is available. More so than ever, it is important to not lose sight
of the forest for the trees.

BECAUSE EASY IS BETTER. THE ADVANTAGES OF
THE AS-INTERFACE SYSTEM
Today, and unfortunately way too often, the
degree of innovation of technical systems is proportional to the
complexity of the developed solution. Economically, this leads to
high investment costs in the beginning, and therefore to a slow
acceptance of the technology itself. AS-Interface was developed
with a totally different goal in mind. It was supposed to be easy.
Easy and economical.
The development goal for AS-Interface was
not to come up with a universal fieldbus for all aspects of
automation, but with an economically reasonable system for the
lower field level. AS-Interface was developed to link binary
sensors and actuators by using a simple installation technology,
and then to connect them to a higher control level. The inventors
of AS-Interface clearly reached their goal. Until this very day,
the system shines because of the following impressive
- AS-Interface uses a single two-conductor flat cable to supply
power to the components and enable data transfer. The complex cable
trees necessary for parallel wiring are omitted, and therefore
considerable savings in terms of material and installation costs
- AS-Interface is installed using a simple piercing technology.
The Click-and-Go principle enables the installer to mount
components safely and free of errors.
- AS-Interface can be used with any network topology.
- AS-Interface impresses through its easy configuration options.
This not only reduces the expenditures during start-up, but also
enables faster troubleshooting and therefore reduces plant down
This is how easy installation can be using the AS-Interface

installations are always free of errors - is placed in the mounting
