Features:
- Dual ASi-3 Master with Single Power Supply
- PROFIBUS DP Interface with Auto-Baud Detection
- RS232 Diagnostic & Configuration Interface
- Comprehensive ASi Network Diagnostics
- Stainless Steel Housing for Industrial Environments
The BWU1777 is specifically configured as a Double Master gateway, meaning it contains two independent ASi-3 master controllers capable of managing two separate ASi networks simultaneously. Both networks are powered from a single integrated power supply with built-in data decoupling, supporting up to 4 A per ASi circuit (max. 8 A total).
The BWU1777 Bihl+Wiedemann ASi-3 PROFIBUS Gateway may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Local diagnostics and configuration are facilitated through an RS232 diagnostic interface accessible via a dedicated service port on the gateway front panel. Using Bihl+Wiedemann's proprietary configuration software, technicians can monitor ASi slave status, read detailed fault messages, perform addressing operations, and update gateway firmware without disturbing the PROFIBUS communication link. The gateway features a 7-segment display (or LCD menu on enhanced variants) that shows ASi slave addresses, error codes, and operational status in plain text, dramatically reducing troubleshooting time compared to cryptic LED-only indicators.

Connect the main AS-i Power Supply (e.g., a 4A or 8A module) directly to the AS-i 1 power input terminals.Do not connect an external power supply to the AS-i 2 circuit terminals; the BWU1777 internally decouples and routes power from Circuit 1 to Circuit 2.Wire the respective field networks to the standard AS-i 1 (+ / -) and AS-i 2 (+ / -) black/yellow flat cable networks.Ensure proper grounding and shield connection to the functional earth terminal to preserve the gateway’s potential-free, ground-symmetrical architecture.
