WebA CAN network can be configured to work with two different frame formats: the base frame format (CAN 2.0A & CAN 2.0B) which supports 11-bit identifiers, and the extended frame format (CAN2.0B only) which supports 29-bit identifiers by allowing the addition of an 18-bit identifier extension. An identifier extension bit (IDE) determines if the 18 ... Web1 jun. 2012 · To support these efforts, the CAN protocol was extended by the introduction of a 29-bit identifier. This identifier is made up of the existing 11-bit identifier (base ID) and an 18-bit extension (ID extension). Thus the CAN protocol allows the use of two message formats: StandardCAN ( Version 2.0A ) und; ExtendedCAN ( Version 2.0B )
