Controller Area Network
CAN Identifier
Identifier for CAN data and remote frames as defined in ISO11898-1
Destination Address (see also PGN and PDU1 Format)
Electronic Control Unit
Is a functional unit that controls one or more systems in a J1939 network/engine application
Group Extension (see also PGN and PDU2 Format)
Is a CAN based protocol used for communication with a motor, engine or generator.
Is an extension of J1939 especially adjusted to requirements in nautical environments (shipping and
offshore applications)
Protocol Data Unit
Is the J1939 term for a 29 bit CAN-ID and the data of a CAN frame
PDU Format
The PF byte is located in bits 8 to 15 of the PGN.
PDU 1 Format is used in peer to peer communication.
In PDU 1 format, the PF field is in the range K0 to K239 (H00 to HEF). The PDU Specific (PS) in the
next 8 bits contains the destination address (DA) of the message.
PDU 2 Format is used for broadcast messages and transports the group extension (GE) information
in the PDU Specific (PS) field.
Parameter Group Number
The PGN assigns a number to a certain group of information.
The single data fields within the PGN are called SPN.
PDU Specific
This field of the PGN will either contain the Destination address or Group Extension information
Remote Transmission Request
An RTR message can be used to request information from the network (request certain information
to be sent in response)
Society of Automotive Engineers
Is an organization that develops standards for automotive environment (like the SAE J1939
standards)
Suspected Parameter Number
The SPN assigns a number to the detailed definition of a data set. This definition includes the
description, data length, type and range.
e.g. SPN 175 "Engine Oil Temperature"
Data length: 2 bytes
Resolution: 0.03125 °C/bit, -273 °C offset
Data range: -273 to 1735 °C
transmission type
Defines the event that triggers the transmission of a message
Data Length Count, this value defines how many bytes are transported in a CAN data frame (0 to 8
byte).
In this manual, DLC is also used for the total byte count of a user configured data packet, even if the
data is transported by more than a single CAN telegram.
Request To Send/Clear To Send
Handshake mechanism used by J1939 to transport data blocks exceeding 8 data bytes in multiple
CAN messages to a certain target node
Broadcast Announce Message
Similar to "RTS/CTS," this is a mechanism to transport data blocks exceeding 8 bytes, but a BAM
transmission is broadcast to all nodes and no handshake is executed
