Bihl+Wiedemann BW1660 AS-i 3.0 Ethernet IP Gateway

The BW1660 AS-i 3.0 EtherNet/IP Gateway from Bihl+Wiedemann is a stainless‑steel, IP20‑rated gateway that bridges two AS‑i networks to EtherNet/IP, enabling AS‑i 3.0 devices to be managed by a PLC over Ethernet/IP. It provides two ASi‑3 master interfaces in a single rugged enclosure, making it suitable for on‑machine or panel mounting in demanding environments. The gateway features an Ethernet TCP/IP interface (IEEE 802.3) with an RJ‑45 connector and supports Modbus TCP in addition to EtherNet/IP communications for flexible integration with existing control systems. For diagnostics and safety monitoring, it offers an Ethernet diagnostic interface that allows access to the AS‑i Master and Safety Monitor via Bihl+Wiedemann software. This BW1660 variant is built for Class 1 Division 2 environments (Group A, B, C, D, T‑Code 4), reflecting suitability where hazardous locations exist when properly implemented. With two ASi networks and two ASi‑3 masters, it can coordinate multiple AS‑i devices and deliver data to a host PLC through a single Ethernet/IP connection, reducing wiring complexity and setup time. Typical applications include machine automation lines, packaging equipment, and other industrial processes where AS‑i sensors and actuators must be centrally monitored and controlled from an EtherNet/IP capable controller.
