FAQ CAN Signals
The example here shows a signal (e.g. engine speed) is located in this CAN frame’s Data field at position Start Bit of 48, and its length is 16 bits. Also, we show the Data field is a total of 8 Bytes long (DLC 8). There are three main formats in CAN â€“ Intel, Motorola Forward and Motorola Backward. A very commonly used format in the automotive sector is Motorola Backward. Intel is designated as the standard usage in all J1939 applications. Motorola Forward is still used, but not commonly. It is considered confusing to work with.
