Logo Bihl+Wiedemann GmbH

Innovative Partner for Automation

Bihl+Wiedemann ist ein mittelständisches, inhabergeführtes Unternehmen, das 1992 von Jochen Bihl und Bernhard Wiedemann in Mannheim gegründet wurde. Wir entwickeln und fertigen komplette Automatisierungslösungen für die funktionale Sicherheit sowie für die Datenkommunikation in Maschinen und Anlagen. Unsere Produkte sind weltweit in verschiedensten Branchen im Einsatz, zum Beispiel bei führenden Herstellern von Konsum- und Investitionsgütern.

 

Für unsere Kunden möchten wir vor allem ein Innovationspartner sein:

Unsere Entwicklungskompetenz als Wegbereiter für individuelle Anforderungen.

 

Führend mit AS-Interface seit 1995

Bihl+Wiedemann ist Technologieführer in der Automatisierungs- und Sicherheitstechnik mit AS-Interface (ASi). Wir waren an der Entwicklung sämtlicher ASi Generation maßgeblich beteiligt. Unser ASi Master erhielt 1995 als erster ein Zertifikat von AS-International e.V., der ASi Organisation mit 300 nationalen und internationalen Partnern. Auch bei der Markteinführung von ASi-5 Geräten waren wir 2019 Vorreiter. Mit der neuen ASi Generation lassen sich größere Datenmengen jetzt deutlich schneller übertragen. Unsere ASi-5 Module ermöglichen seit 2019 z. B. die einfache und komfortable Anbindung verschiedenster IO-Link-Devices – und seit 2020 die kostengünstige Lösung komplexer Anforderungen in der Antriebstechnik.

 

Im Bereich der funktionalen Sicherheit mit ASi Safety at Work gehören wir seit fast 15 Jahren zu den führenden Anbietern. ASi-5 Safety Geräte haben wir 2022 als erster vorgestellt. Mit ihnen lassen sich viele sichere und nicht-sichere Signale unter nur einer ASi Adresse nutzen.

 

Unser komplettes ASi Produktportfolio umfasst Master/Gateways, Module, Sicherheitskomponenten, Buskoppler/Mastersimulatoren sowie selbst entwickelte Software.

International Subsidiaries and Sales Partners

A combination of innovative strength and long-standing customer relationships has enabled us to grow continuously for many years. In addition to our headquarters in Mannheim, Bihl+Wiedemann owns subsidiaries in the USA, China, Turkey, Denmark and Spain. We are now also represented by international sales partners in more than 30 countries.

We are committed to environmental and climate protection

Reducing CO₂ emissions has never been more important than it is today. We have been covering a large part of our energy requirements with our own solar panels since 2010, and the first electric vehicles have been in use at our company since 2019. To constantly improve our energy efficiency and environmental protection, we also make use of an energy management system that complies with ISO 5001 and an environmental management system that complies with ISO 14001. Solar modules in three systems have a total output of 270 kWp and generate an annual energy volume of 134,000 kWh (2021).

Technological Principles

AS-Interface

AS-Interface (ASi) is a globally standardized fieldbus system for the first level of automation. ASi connects sensors and actuators with a controller via a single two-conductor profile cable. The yellow ASi cable transmits power and data at the same time. The main benefits of ASi are, among others, dramatically less wiring, free choice of topology and cost-efficient integration of safety on the same infrastructure. The latest ASi-5 generation can now handle larger data volumes at much higher transmission speeds and it enables intelligent sensors such as IO-Link to be integrated with ease.

 

More about the AS-Interface

ASi Safety at Work

Safety-related aspects play an important role in an increasing number of automation solutions, especially where hazardous movements pose a safety risk to humans. Regulations in this regard are set out, for instance, in the EU Machinery Directive (Directive 2006/42/EC) or in the occupational safety regulations of the respective countries. Thanks to the Safety at Work concept of the AS-Interface, safety-related components, such as safe sensors and actuators as well as safety monitors, can be seamlessly integrated into almost all commonly used automation systems.
