ASi EtherNet/IP + ModbusTCP Gateways – High Availability and Ideal for Rockwell PLCs
ASi EtherNet/IP + ModbusTCP Gateways with and without integrated Safety monitor: Immediately available from us in large quantities
Are you looking for ASi gateways with EtherNet/IP + ModbusTCP interface to connect AS-Interface (ASi) to an EtherNet/IP + ModbusTCP control system or Rockwell PLC? Then we recommend two items: BWU3822 (for 1 ASi circuit) and BWU3736 (for 2 ASi circuits).
Do you also need Safety? Then the "Bihl+Wiedemann's Choice" articles BW3542 (for 1 ASi circuit) and BWU3543 (for 2 ASi circuits) are ideally suited. Both gateways have an integrated safety monitor and thus make it possible to solve safety functions completely without expensive higher-level safe control.
For standard applications: ASi EtherNet/IP + Modbus TCP Gateways without integrated Safety monitor
We recommend the "Bihl+Wiedemann's Choice" articles BWU3822 and BWU3363 for almost all standard applications. Here you also benefit from our new power supply generation.

BWU3822
1 ASi circuit, 1 ASi-3 Master
- integrated decoupling
max. 4 A per ASi circuit
Diagnostics and configuration via EtherNet/IP + ModbusTCP

BWU3736
2 ASi circuits, 2 ASi-3 Masters
- integrated decoupling
max. 4 A per ASi circuit
Diagnostics and configuration via EtherNet/IP + ModbusTCP
However, if you need more than 4A per ASi circuit, you can also use the ASi EtherNet/IP + ModbusTCP Gateways BWU3734 (for 1 ASi circuit) and BWU3735 (for 2 ASi circuits). Both articles do not have an integrated decoupling.

BWU3734
1 ASi circuit, 1 ASi-3 Mastes
max. 8 A per ASi circuit
Diagnostics and configuration via EtherNet/IP + ModbusTCP

BWU3735
2 ASi circuits, 2 ASi-3 Masters
max. 8 A per ASi circuit
Diagnostics and configuration via EtherNet/IP + ModbusTCP
For Safety applications: ASi EtherNet/IP + ModbusTCP Gateways with integrated Safety monitor
We recommend the articles BWU3542 and BWU3543 for almost all Safety applications. Here you also benefit from our new power supply generation.

BWU3542
- 1 ASi circuit, 1 ASi-3 Master
- integrated decoupling
max. 4 A per ASi circuit
Diagnostics and configuration via EtherNet/IP + ModbusTCP or Ethernet diagnostic interface
- Safety communication via Safe Link

BWU3543
- 2 ASi circuits, 2 ASi-3 Masters
- integrated decoupling
max. 4 A per ASi circuit
Diagnostics and configuration via EtherNet/IP + ModbusTCP or Ethernet diagnostic interface
- Safety communication via Safe Link
However, if you are dependent on CIP Safety communication - e.g. due to the use of safe Rockwell PLCs - you can alternatively use the ASi EtherNet/IP + ModbusTCP gateway BWU3683 (for 2 ASi circuits). The gateway offers integrated CIP safety communication for easy integration of the safe signals into the safe Rockwell PLC.
This device is usually also in stock.

BWU3683
- 2 ASi circuits, 2 ASi-3 Masters
- integrated decoupling
max. 4 A per ASi circuit
Diagnostics and configuration via EtherNet/IP + ModbusTCP or Ethernet diagnostic interface
- Safety communication via Safe Link
- CIP Safety über EtherNet/IP communication integrated
