- Manufacturer: Bihl+Wiedemann
- MFR Part Number: BWU1703
- Krones Part Number: 0-900-85-353-7 (0900853537)
- Device Type: AS-i 3.0 to PROFIBUS Gateway
- Number of AS-i Masters: 2 Masters (Supports up to 2 distinct AS-i networks)
- Housing Material: Stainless Steel
- Protection Rating: IP20 (Protected against solid bodies >12.5mm, no water protection)
- Operating Voltage: 30V DC (via AS-i) / Compatible up to standard 110V–240V supply architectures
- On the AS-i Side: The unit functions as a master controller for two separate AS-i networks. It continuously polls and collects digital/analog input signals from connected field components like proximity switches, photoeyes, and valve positioners.
- Duplicate Address Recognition: Automatically detects if two slave devices on the same AS-i loop have accidentally been assigned the same node address, preventing erratic signal behavior.

- Serial Ports: 1 DB9 male connector (Supports RS-232, RS-422, or 2-wire/4-wire RS-485)
- Ethernet Ports: 2 RJ45 ports (10/100 Mbps) functioning as a built-in switch for easy daisy-chaining
- Configuration Methods: Web Console (HTTPS/HTTP), MGate Manager Utility, Serial Console, or Telnet
- Power Requirements: 12 to 48 VDC terminal block input
- Mounting: Built-in rugged DIN-rail mounting hardware
- Auto-Device Routing (Patent Pending): Eliminates complex slave ID mapping tables. The gateway automatically detects commands from a SCADA system and routes them dynamically to the correct endpoints, drastically shortening configuration times.
- Priority Control for Urgent Commands: Allows users to assign priority to specific Modbus commands to avoid communication lag in large or critical networks.
- Serial Redirector Function: Allows an existing serial master device to maintain direct communication with local serial slaves through a mapped path without altering the software architecture.
- Flexible Routing: Serial port traffic can be routed strictly by IP address, TCP port number, or Modbus Slave ID mapping.
- Default IP Address: 192.168.127.254

- Serial Ports: 4 x DB9 Male (Software-selectable RS-232, RS-422, or RS-485)
- Baud Rate: 50 bps to 921.6 kbps
- Ethernet Port: 1 x 10/100BaseT(X) port (RJ45 connector, Auto MDI/MDI-X)
- Magnetic Isolation: Built-in 1.5 kV isolation protection for Ethernet
- Device Routing: Auto-Device Routing (Automatically detects Modbus requests and populates slave ID routing tables via a single click)
- Security Functions: HTTPS, SNMPv3, Local database, Authentication, Encryption
- Input Power: 12 to 48 VDC
- Network Bridging: Ideal for connecting legacy serial PLCs, meters, and sensors to modern SCADA software platforms via Ethernet.
- Auto Device Routing: Eliminates the tedious, error-prone manual process of building a slave ID mapping routing table. Instead, it listens to traffic and maps connections with a single mouse click, reducing commissioning times.
- Mixed Serial Infrastructure: Because each of the 4 ports can be configured independently, you can run Modbus RTU on one port and Modbus ASCII on another, or use completely different baud rates within the same gateway.
