Communication in Simulink

Use MathWorks^® virtual CAN channels to set up transmission and reception of CAN messages in Simulink.

Use MathWorks virtual CAN FD channels to set up transmission and reception of CAN FD messages in Simulink. The virtual channels are connected in a loopback configuration.

Observe the message processing behaviors of the CAN Receive and CAN Unpack blocks in multiple modeling scenarios. This example demonstrates two cases, with and without using the function trigger f() port of the CAN Receive block. The outputs of the model indicate the number of CAN messages unpacked for downstream processing in each case. The example uses MathWorks virtual CAN channels to send CAN messages from MATLAB to the Simulink model. These modeling practices and behavior also apply to the CAN FD protocol using the Vehicle Network Toolbox CAN FD blocks.

Set up periodic transmission and reception of CAN messages in Simulink® using MathWorks® virtual CAN channels. The virtual channels are connected in a loopback configuration.

Use event-based CAN message transmission in Simulink® with Vehicle Network Toolbox™. This feature allows for CAN and CAN FD message transmission when a change in data from one time step to the next is detected.

Log and replay CAN messages using MathWorks® Virtual CAN channels in Simulink®. You can update this model to connect to supported hardware on your system.

Log and replay CAN FD messages using MathWorks virtual CAN FD channels in Simulink. You can update this model to connect to supported hardware on your system.

Programmatically construct a Simulink® model to introduce CAN or CAN FD communication using a CAN DBC-file. With the add_block and set_param functions of Simulink, one can add and fully configure Vehicle Network Toolbox™ blocks to add network communication to a basic algorithm. The DBC-file contains the CAN messages and signal details. The primary focus is to programmatically configure CAN and CAN FD Pack and Unpack block parameters. This can significantly increase model construction efficiency.

Construct a test application user interface (UI) and connect it to a Simulink model using virtual CAN channels.

Use Vehicle Network Toolbox and Simulink to implement a distributed Electronic Control Unit (ECU) network over CAN for an automobile.

Use Vehicle Network Toolbox and Simulink to implement a Controller Area Network (CAN) in a remote manipulator arm.

Set up CAN communication between host-side CAN Vector blocks and target models. This example uses:

Use ARXML files with the CAN Pack and CAN Unpack blocks.
