AS-Interface

in the Fully Automatic Crane System of Environmentally-friendly Biomass Heating and Power Stations

AS Interface from Siemens used to network the A+S Schuster crane system
Working in cooperation with the crane system construction company A+S Schuster and VA GmbH in Peiting, Germany, the wood working company Schößwendter Holz has constructed an environmentally- friendly biomass heating and power station at its site in Saalfelden/ Salzburg. This station has a fully automatic crane system for charging the firing bunker. A large part of the automation runs over the AS Interface field bus system.
The heating station now runs fully automatically!
The firing bunker of the heating station is charged by the A.S Schuster crane system, which is equipped with AS Interface. For some years now, A.S Schuster of Peiting, Germany has specialized in special solutions for transport tasks. There are now more than 4,000 of its systems (series crane systems and special constructions) in operation across Europe. In agreement with VA GmbH (VA = process engineering plants) it was decided to interface the distributed I/O of this and many comparable crane systems using the actuator-sensor interface field bus system (AS Interface).
Why AS Interface?
The decisive advantage of the AS Interface technology was the drastic reduction of wires that needed to be laid along the trailing cable that was previously an integral part of crane applications. Using conventional wiring, approx. 120 lines used to be laid along the trailing cable, whereas this crane system requires a mere 10 wires – 5 for AS Interface, 5 for the load. It goes without saying that this makes installation considerably easier all round.
The application advantages of the AS Interface from Siemens:
Simple and effective remote maintenance. The diagnostics of the system can be performed over touch panel from the Schößwendter Holz site. An online connection enables communication over greater distances.
Bus technology makes maintenance of the system more effective. Faults and cable breaks can be localized quickly and easily.
Uncomplicated expansion of the system.
AS Interface also supports the processing of analog data over analog modules. These automatic crane systems also make use of the ability to determine the load through AS Interface using force transducers. Using the "minimum load" limit value, the system is able to detect that it has touched down.
