This example shows how to transfer data through CAN bus. The model sends data within one computer, from one CAN channel to another. The two CAN channels can be either virtual channels or physical channels on a dual-channel CAN device. Two different CAN messages using different message identifiers are being transmitted. You can modify the model to communicate between two computers by splitting this model into its send and receive parts and running the models on two computers. The yellow blocks are used to send the data, the blue blocks are used to receive the data.
Note: This model runs on Microsoft Windows only.
To switch to normal mode if needed, on the Simulation tab, select Normal mode.
To start the real-time execution, on the Simulation tab, click Run.
To start the real-time execution in external mode, on the Desktop Real-Time tab, click Run in Real Time. The model builds, connects to Simulink in external mode, and starts.
These commands open the model and suppress warning about board not installed.
w = warning('off', 'sldrt:blkgui:boardnotonlist'); open_system(fullfile(matlabroot,'toolbox','sldrt','sldrtexamples','sldrtex_canio')); warning(w);
close_system(find_system(gcs ,'BlockType', 'Scope'));
