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 ... WebThe latest is CAN 2.0, published in 1991. This specification has two parts. Part A is for the standard format with an 11-bit identifier, and part B is for the extended format with a 29-bit identifier. A CAN device that uses 11-bit identifiers is commonly called CAN 2.0A, and a CAN device that uses 29-bit identifiers is commonly called CAN 2.0B.

A dominant IDE bit defines the 11-bit standard identifier, whereas recessive IDE bit defines the 29-bit extended identifier. DLC: DLC stands for Data Length Code, which defines the data length in a data field. It is of 4 bits. Data field: The data field can contain upto 8 bytes.
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 )
