PGN. 2 Parameter Group Number (PGN) a Parameter Group in the data field of a CAN data frame, it will be expressed in 24 significant byte first (see Table 2 where it is stated the MSB is sent third, middle byte first). The DBC file is an ASCII based translation file used to apply identifying names, scaling, offsets, and defining information, to data transmitted within a CAN frame. The bit encoding looks like this: For example, the API can decode a CAN Id into its component parts: NB: The API expects a 32-bit integer as a HEX string. • If another ECU claims the same address, the ECU with the lower value NAME field wins.
