This effectively corresponds to immediately … 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.

WebApr 26, 2024 · CAN bus considers the 11 bit indentifiers to have a higher priority than the 29 bit identifiers (because the two types of "protocol", "11" and "29", can coexist in the same bus). Hence: In the case of a 29 bit extended frame, the RTR bit has been moved to the end of the message so it doesn't play in the priority bitwise arbitration of the 29 ...

Webbus. Since the CAN protocol defines a logical 0 as the dominant state, the lower the number in the arbitration field, the higher priority the message has on the bus.
