J1939 CAN Transport Layer

Generate and consume J1939 messages that are transported by CAN hardware

  • Library:
  • Simulink Real-Time / J1939

Description

The J1939 CAN Transport Layer block handles CAN messages that your model transmits or receives by using Simulink® Real-Time™ CAN library blocks.

Connect the input side of the block to a block that receives CAN messages. Connect the output side of the block to a block that transmits the J1939 messages over CAN. Set up the transmitting block so that a CAN message is sent only when an J1939 message is available. Otherwise, the block sends 0 byte data when J1939 messages are not available, causing undefined behavior.
