Basic identifiers of the CAN objects
The CAN bus system is message-oriented. Each message has an unambiguous identifier.
With CANopen, there is only one sender for each message for device-orientation.
Except for the network management and the sync telegram, the identifier contains the
node address of the controller:
Identifier (COB-ID) = basic identifier + adjustable node address (node ID)
The identifier assignment is specified in the CANopen protocol.
The basic identifier in accordance with the CANopen specification ex works is preset to the
following values:
