Can remote frame format

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). 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.

WebNov 16, 2024 · There are 5 types of frames in CAN protocol; Data Frame (DF): Carries Data from transmitting node to receiving node. Remote Frame (RF): Some times, a node might want to request some data from another which is made possible by Remote frame. There are two differences between data and Remote frames. WebThe Remote Frame is just like the Data Frame, with two important differences: is explicitly marked as a Remote Frame (the RTR bit in the Arbitration Field is recessive) there is no Data Field. The intended purpose of the Remote Frame is to solicit the transmission of the corresponding Data Frame.
