Hi,

is there a way to communicate over a CANOpen bus with the IOT2040? I can't find any decent drivers or libraries. 

Thanks in advance.

Hi,

please look in internet for CanBus shield for arduino (mostly mcp2515 based).

Then search for CanOpen library for arduino. You can compile the library with arduino Ide.

Its possible, that you must adapt the sketch for IOT2000.

Good luck.
