Time ID Extended Name Data Length Signals Error Remote The example uses MathWorks virtual CAN channels connected in a loopback configuration. Vehicle Network Toolbox provides J1939 Simulink blocks for receiving and transmitting parameter groups (PG) via Simulink models over CAN. This example also uses the J1939 DBC-file PowerTrain_J1939.dbc, provided with the Vector sample configuration. The BLF-file used in this example was generated from Vector CANoe using the "System Configuration (J1939)" sample configuration, and modified using MATLAB and Vehicle Network Toolbox. This example performs data replay of the originally logged CAN frames over a CAN bus from MATLAB and receives in a Simulink model using the J1939 Network Configuration, J1939 Node Configuration, J1939 CAN Transport Layer, and J1939 Receive blocks. Since CAN is the basis of data transfer in a J1939 system, the tool used in the field by default logs J1939 data as CAN frames. J1939 is a higher-layer protocol that uses the Controller Area Network (CAN) bus technology as a physical layer. The example takes you through a part of the model-based workflow using field data to recreate a fault that was present in the Simulink algorithm before it was deployed onto an ECU, and can be extended to test any algorithm model to debug faults.

The Simulink model runs a simple horsepower estimator algorithm to trigger a fault that might have occurred in the field.

This example shows how to replay J1939 data from a BLF-file acquired from a J1939 system in a real-world application, such as a vehicle running in the field.
