Hi there,

similar to this thread, I need to control a motor via the CANopen protocol (unfortunately I don't really have any relevant experience with CANopen). As it still seems not be properly resolved, I thought I would post another question to draw some attention to this issue. I basically have a Simulink Real Time lab set-up, but from what I understand from the Simulink documentiation this would only allow me to communicate via CAN/ CAN-FD and J1939.

The question now is how to link Simulink and CANopen. As I understand it, to integrate the open-source implementation would be very time consuming and commercial solutions are not really an option (but I am still open to suggestions to consider). I found CANopen <-> J1939 converters (as Simulink Real-time and the Vehicle Network toolbox support J1939), might that be a practical solution? ...But am pretty much out of ideas otherwise.

Any help would be greatly appreciated!

Lukas

Hi Lukas,

I see you are working with Simulink Real-Time. For this use case, I think the most appropriate way would be to look into CANopen I/O modules from Speedgoat. You can find more information here:

Best,
