A CAN network can be configured to work with two different message (or "frame") formats: the standard or base frame format (described in CAN 2.0 A and CAN 2.0 B), and the extended frame format (described only by CAN 2.0 B). The only difference between the two formats is that the "CAN base frame" supports a length of 11 bits for the identifier, and the "CAN extended frame" s… WebFor example, a single CAN frame will contain a 29-bit CAN ID that can be translated to an 18-bit J1939 PGN.

WebFor example, a single CAN frame will contain a 29-bit CAN ID that can be translated to an 18-bit J1939 PGN. In turn, the CAN frame data payload will contain a number of J1939 SPN signals. If you're logging J1939 data , …

WebCAN bus represents the two lowest layers (1: Physical, 2: Data Link). This means that CAN simply enables the transmission of frames with an 11 bit CAN ID, a remote transmission (RTR) bit and 64 data bits (fields relevant to higher-layer protocols). In other words, CAN bus plays the same role in CANopen as it does in e.g. the J1939 protocol. importance of mathematics in natureWebIdentifier Extension (IDE) The Identifier Extension bit differentiates standard frames from extended frames. Because the IDE bit is dominant (0) for standard frames and recessive (1) for extended frames, standard frames are always higher priority than extended frames.
