Product Details And Specifications

Bihl+Wiedemann BWU Series Technical Notes

The Bihl+Wiedemann BWU series represents one of the most widely deployed AS-Interface (AS-i) gateway and master module families in global heavy industry. Installed across chemical processing plants, nuclear facilities, oil refineries, and large-scale manufacturing lines, BWU-series devices serve as the critical communication bridge between AS-Interface field networks and higher-level fieldbus or industrial Ethernet systems. Their deterministic cycle times, robust DIN-rail form factor, and compliance with AS-i Specification Rev. 3.0 have made them a default specification in safety-critical automation projects across Europe, Asia, and North America. The BWU1703 specifically functions as a PROFIBUS DP gateway, enabling AS-i network segments of up to 62 slaves to communicate with Siemens S7, ABB, and other PROFIBUS-based DCS/PLC architectures.
