Can frame extended id
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. WebIdentifier 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. Data Length Code (DLC)
