BridgeWay 2.0 Ethernet to J1939 Gateway

The BridgeWay 2.0 Ethernet to J1939 Gateway (p/n BW4031) enables an EtherNet/IP Scanner or Modbus TCP Master PLC, HMI or other compatible device to perform monitoring and control on an SAE J1939 (CAN) network.

The BW4031 can immediately expand the features and capabilities of your products and systems by enabling:

  • Access to J1939 data for real-time monitoring/viewing from:
    • ECUs
    • Sensors
    • I/O
    • Any other devices that transmit J1939 PGN messages (including DM1 and DM2 diagnostic messages)
  • Transmission of J1939 PGN messages to:
    • Control engine speed or select a transmission gear
    • Command actuators and sensors
    • Control I/O
    • Simulate a device/ECU
    • Command/control other devices/systems that support SAE J1939

Commonly Asked Questions

How can I purchase a BW4031 device?
Please contact us for all inquiries regarding price, availability and distribution.
What protocols are supported?
Supported protocols include:

  • EtherNet/IP Adapter
  • Modbus TCP* Slave
  • J1939 (125k, 250k and 500k)

Note: The BW4031 can also connect to SIEMENS Controllers using Modbus TCP.

What is included with the BW4031?
Each device comes with the following:

  • 3 Pin Phoenix connector for power
  • 6 Pin mini-Phoenix connector for J1939
  • BWConfig 2.0 configuration tool
  • User Manual
What is required, but NOT included?
  • A properly-wired and terminated J1939 network
  • An EtherNet/IP or Modbus TCP device (PLC, HMI, etc.)
  • Proper 24 VDC power
  • A computer to run the BridgeWay configuration tool, BWConfig 2.0
  • A Micro USB to USB cable to connect the computer running BWConfig 2.0 to the BridgeWay device
Can I use one BW4031 to read/write PGN messages on two or more J1939 engine networks?
No, this would require that you connect these networks together physically. Engine control systems are generally designed as self-contained J1939 networks and the CAN addresses (e.g. Address 0 for the engine ECU) would collide with the ECU address for another engine network if they were tied together. You may also run into termination or network trunk/drop length issues.

In this scenario, one BridgeWay device will be required for each J1939 engine network. The BridgeWay can then have the same J1939 (CAN) address on each individual network, but the host (Ethernet, Modbus RTU or PROFIBUS) address will have to be unique for each gateway if using a single PLC to read/write data through each gateway.

What J1939 PGN messages does the BW4031 support?

The BW4031 supports all standard SAE PGN messages, proprietary range PGNs and DM1 and DM2 diagnostic messages. Configure the BW4031 for the input and output PGNs/SPNs you need for your application. The free BWConfig 2.0 tool helps you accomplish this. The BW4031 is not OEM-specific, it is J1939-specific.
