Product Description (Detailed Explanation)

The BWU2602 is a “Double Master” gateway, meaning it can manage two separate AS-i networks simultaneously. It is designed to integrate simple field devices (sensors, actuators, and safety switches) into complex control architectures using EtherNet/IP (standard for Allen-Bradley/Rockwell) or Modbus TCP.

• Gateway Function: It translates data from the AS-i bus into Ethernet packets that a PLC can understand.

• Integrated Screen: Features an LCD display for on-site diagnostics, address assignment, and status monitoring without needing a PC.

• Double Master: Supports up to 124 AS-i slaves (62 per circuit), providing massive I/O expansion capabilities.

Product Parameters (Technical Specifications)

Product Advantages (Key Benefits)

• Protocol Versatility: Supports both EtherNet/IP and Modbus TCP, allowing the same hardware to be used in various PLC environments.

• Reduced Wiring: AS-i technology allows for power and data to be carried over a single 2-core flat cable, drastically reducing installation time and copper costs.

• Built-in Switch: The dual RJ45 ports allow for “Daisy Chaining” Ethernet cables between multiple gateways, eliminating the need for external network switches.

• Easy Diagnostics: The LCD display provides instant error codes (e.g., “Duplicate Address” or “Slave Failure”), significantly reducing downtime during troubleshooting.

• Standard-Compliant: Fully compliant with AS-i Specification 3.0, ensuring compatibility with all certified AS-i slaves from any manufacturer.

Precautions (Important Notes)

• AS-i Power Supply: This gateway must be powered by a dedicated AS-i Power Supply (30V with data decoupling). Using a standard 24V DC power supply will prevent the data signal from functioning.

• Addressing: Each slave on the network must have a unique address. Use the gateway’s front buttons or a handheld addressing tool before connecting slaves to the bus.

• Cable Length: The maximum length for an AS-i cable segment is 100 meters. If longer distances are required, AS-i Repeaters or Terminators must be used.

• Network Security: When using Modbus TCP over a factory network, ensure the gateway is protected by a firewall to prevent unauthorized access to the I/O data.

Product Applications (Typical Use Cases)

• Conveyor Systems: Managing hundreds of photo-eyes and motor starters across long distances in distribution centers.

• Packaging Machinery: Integrating multiple proximity sensors and pneumatic valves into a Rockwell Logix controller.

• Food & Beverage: Connecting stainless steel sensors and valve manifolds in washdown areas back to a central control room via Ethernet.

• Automotive Assembly: Collecting I/O data from robot cells where high-flexibility and rapid modular changes are required.
