Product Description

The BWU2267 functions as a central controller for two independent ASi circuits. It collects data from sensors and actuators on the factory floor and transmits it to a PLC via Ethernet-based protocols. A defining feature is its integrated Safety Monitor, which allows the device to process safety-critical signals (such as emergency stops and light curtains) and execute safe shutdowns without requiring an external safety controller.

Product Parameters

• Fieldbus Interface: EtherNet/IP and Modbus TCP (Integrated 2-port switch).

• ASi Master Configuration: 2 ASi Masters for controlling two separate ASi networks.

• Safety Category: SIL 3 (IEC 61508) and Performance Level e (PLe, EN ISO 13849-1).

• Inputs/Outputs:

  • 4 local digital inputs.

  • 2 safe relay outputs.

  • 2 fast electronic safe outputs.

• Power Supply: Designed for “1 Power Supply, 2 ASi Networks,” optimizing the internal data coupling.

• Display: Plain-text display for on-site diagnostics and status monitoring.

• Protection Rating: IP20 (intended for control cabinet installation).

• Data Transmission: Optimized for ASi-3 standard communication.

Product Advantages

• Hardware Consolidation: By integrating the gateway and the safety monitor into a single unit, it significantly reduces cabinet space and wiring complexity.

• Cost Savings: The ability to power two ASi circuits from a single standard 30V power supply eliminates the need for multiple specialized ASi power units.

• Ease of Replacement: Includes a plug-in memory card (chip card) that stores all configuration data, allowing for quick device replacement without a PC.

• Robust Diagnostics: Provides detailed feedback on the ASi bus health, including earth fault detection and duplicate address recognition.

Important Considerations

• Software Configuration: The safety logic and gateway settings must be configured using the ASIMON360 or AS-i Control Tools software.

• Ambient Environment: Since the device is rated IP20, it must be protected from conductive dust, moisture, and extreme temperatures inside a suitable enclosure.

• Safety Limits: While the device handles safety logic, the total number of safe slaves and the complexity of the logic must stay within the memory limits of the integrated monitor.

• Compatibility: This model is designed for ASi-3. For applications requiring the higher bandwidth of ASi-5, a different model in the Bihl+Wiedemann lineup would be necessary.

Product Applications

• Conveyor and Logistics: Managing large-scale sorting systems where long distances and safety stops are integrated.

• Automotive Production: Coordinating robotic workstations where safe human-machine interaction is required.

• Packaging Industry: Controlling complex machinery with high I/O density and multiple safety zones.

• Food and Beverage: Providing a decentralized control architecture for processing lines that require frequent status updates and emergency stop functionality.
