Can bus communication explained
WebThe ISO 11898 specification details the physical layer requirements for CAN bus communications. CAN is a low-level communication protocol over a twisted pair cable, similar to RS-485. Figure 1. Typical CAN Network . An important feature of CAN is that the bus isn’t actively driven during logic ‘High’ transmission, referred to as ... WebJ1939 is based on CAN, which provides the basic "physical layer" and "data link layer", the lowest layers in the OSI model. Basically, CAN allows the communication of small packets on the CAN bus, but not a lot more than that. Here, J1939 serves as a higher layer protocol on top, enabling more complex communication.
