Commonly Asked Questions
How do I migrate my AB7645 to the new BW4031?
What are the installation requirements?
- 24VDC, see the user manual for the operating voltage range and other specifications
- Ensure the BW4031 is installed on a properly-wired and terminated J1939 network
- Ensure the J1939 network length is within specification (max 40-meter trunk with max 3-meter drops from the trunk)
- Ensure that the BW4031 J1939 node address is unique on the network and is set in a manner as to not interfere with a control network
- Ensure the BW4031 is installed on a properly-wired and segmented Ethernet network
- Ensure that the BW4031 IP Address is unique on the network
How do I configure my BW4031?
How can I schedule output messages when needed?
- Set the rate of the output PGN message to 0, meaning it will not be sent until it is requested on the J1939 by another node.
- Use the message bridging feature, which allows the PLC (or another controlling device) to “on demand” bridge a message from EtherNet/IP or Modbus TCP to a J1939 PGN message that will be sent immediately on the J1939 network.
Can the BW4031 operate at multiple addresses on a J1939 (CAN) network?
Some J1939 applications require that PGN messages be sent by specific CAN addresses on a single J1939 network. e.g. the engine ECU wants to see remote speed control (PGN 0) from address 7 and ignores it from all other addresses. In this scenario, one BridgeWay device will be required for each CAN address that needs to transmit PGN messages. Each BridgeWay will require a unique J1939 (CAN) address (e.g. one at address 7 and the other as address 5) and a unique host (Ethernet, Modbus RTU or PROFIBUS) address if a single PLC is used on a single host network.
