Thanks for posting this reply! I'm under oath of NDA until the info is made publicly available.
The "Device Query" message is something that would be useful if there was more than one type of device that worked on CAN.

I'm assuming there's a typo in here, and they meant "the device's function".
I'm not sure if this command has practical usage. If you send a CAN device a message, using the wrong device type and manufacturer in the device ID, will it respond with the wrong device type and manufacturer?
