In 1995 Bihl+Wiedemann was the first company to receive a certificate from AS-International for their ASi Master. The Master is now used as a reference for the certification for ASi slaves. Other milestones in the company's history include the introduction of the first ASi Master for specification 3.0, the release of the first ASi Master in a stainless steel housing with expanded diagnostic functions (2004), and the membership in AS-Interface's Safety Consortium (2005). Since then Bihl+Wiedemann is among the top names in the field of safety technology using ASi Safety at Work.
Assuring consistent quality has always been of utmost importance for Bihl+Wiedemann. The company is DIN EN ISO 9001 certified.
