The CANopen vendor-ID is used to identify the manufacturer of a CANopen product. It is required since CANopen version 4 and by EN 50325-4. All vendor-IDs are assigned by CiA.

The CANopen vendor-ID is part of the identity object of a CANopen device. The identity object serves as a worldwide unique device address. Several services (e.g. LSS and node claiming) utilize this object to correctly identify CANopen devices, to allow plug and play, and to check the integrity of the whole system.

The CANopen vendor-ID is used to identify the company, and to identify the department within larger organizations.
 

The CANopen vendor-ID is also used by other communication technologies. As some companies develop device exclusively for those, the CANopen vendor-ID range is used as shown.
