WebJan 31, 2024 · CAN Frames Format : The message transfer is done through four types of frames, and they are: Data frames: Carries the data between transmitter and receiver Remote frames: A bus unit can request the transmission of a data frame with the same Identifier by sending this remote frame to the transmitter.
WebRemote frame In CAN communication, a node that will request certain data transmits a remote frame, and then the node that has the data returns a data frame. A remote frame is basically structured by deleting a data field from a data frame (or, by setting the DLC and data field to 0 bytes). cy filename\u0027sWeb3.1 The Bit Fields of Standard CAN and Extended CAN 3.1.1 Standard CAN Figure 2.
