Today we released a new version of our Micro CANopen source code. Updates and changes made include requirements from the latest CANopen conformance test as well as updates to the CiA 447 specific examples. Besides two bug fixes, the changes are:

Device switch themselves automatically to pre-operational when they detect a loss of a heartbeat that they are consuming. In the past this was application code specific, but as the conformance test requires it, we moved this function into the stack. In CiA 447 this is only done for the loss of the gateway’s heartbeat. Reaction to other heartbeat losses remains application code specific.

For CiA 447 devices, the shut down sequence is now also initiated if a gateway is not present. As before, devices wait for the next wake-up message before they try to communicate again.

Micro CANopen customers with a current maintenance and support contract may download this latest version from our servers as described on the delivery note for each product.
