Hi all,
I am trying to add a "Timeout" on the receive side of the CAN bus, so that when a specific amount of time is pass and there is no reception of a new CAN message, a default value will be present in the transmission side. Is that possible? Bellow there is a link with the Simulink Model: https://www.dropbox.com/s/rk1ipb45e6pc2aj/test_can_TO.slx?dl=0
Any answer will be appreciated!

Hi,
You can create a counter and reset it when you get a CAN message (from the function call of the CAN block or an interrupt). If the counter reaches the timeout value before a CAN message is received, than we can trigger a specific subsystem. Regards,

Hi,
Thank you for responding so quickly. I have tried many things using the Counter block(DSP Toolbox), but I can't figure it out how to reset it. The function-call "signal", can't reset or set any of these kind of blocks. Additionaly, I tried to use a Stateflow chart to achieve that, but nothing solid came out. Is there a direct way to convert this function call event into something that can reset a counter?
Best regards
