CAN provides four different types of message frames: Data Frame — Sends data Data transfer from one sending node to one or numerous receiving nodes. Remote Frame — Requests data Any node may request data from one source node.

Error Frame — Reports error condition Any bus participant, sender or receiver, may signal an error condition at any time during a data or remote frame transmission.

Overload Frame — Reports node overload A node can request a delay between two data or remote frames, meaning that the overload frame can only occur between data or remote frame transmissions. Add a comment. Active Oldest Votes. Improve this answer.

The Interframe Space represents the minimum space between frames of any type data, remote, error, overload and the following data or remote frame.

During the Interframe Space intermission , no node can start transmitting a data or remote frame. Only the signaling of an overload condition is allowed see Chapter 4. There is no Interframe space between error and overload frames. The Interframe Space can not necessarily be considered to be a part of a data or remote frame; however, in a well-functioning CAN network, it will always follow behind a data or remote frame. For more detailed information, see also Chapter 4.

In all consequence, the number of average bit stuffing needs to be applied. For more detailed information on frame length and transmission time, refer to Chapter 4. Connection are made via DB9 or 3-way screw terminal. More Information All prices are in USD. Sitemap Powered by BigCommerce. Site Information.

Remote Transmission Request RTR The consumer sends a frame with an identifier to signal that he needs a value for that variable, this bit will indicate that the frame is a request for that value to be sent by the node responsible for the needed variable. Data frame A frame used by producers to emit a variable's value.

RTR is set to dominant 0. Remote frame A frame used by consumers to signal the need for a variable's value. RTR is set to recessive 1. Normal frames have thif flas set to dominant 0. Reserved dominant A reserved bit set to dominant 0. However controllers will never send a value longer than 8 bytes. Acknowledgement slot ACK A field used by producers and consumers to make sure data is properly transmitted.

Note that this field is not affected by stuffing. Data frames vs remote frames Because of the RTR field, in case 2 nodes send 2 frame with the same identifier, a data frame and a remote frame, the data frame will take priority because, after the SOF, the identifier will be the same and the discriminant will be the RTR bit.
