|term|Description|
|:--|:--|
|Address Claiming|Address Claiming forms the network management of SAE J1939 defined in the standard document SAE J1939/81. Address claiming assigns a temporary 8-bit identifier to each ECU connected to one J1939 network. Within this network, the 8-bit identifier is unique. The 8- bit identifier is used as source and target address of parameter groups (messages) transferred via the J1939 network. The address claiming procedure is based on the exchange of AddressClaimed messages (PGN 00EE00).
|J1939 Diagnostics |The SAE J1939 diagnostic layer is defined in the standard document SAE J1939/73. The J1939 diagnostics is functionally similar to the UDS diagnostics, and has recently been extended to support OBD for emission relevant values.
|Parameter |A parameter is a signal of the SAE J1939 application layer. Parameters are uniquely identified by the SPN.
|Parameter Group |A parameter group is a message of the SAE J1939 application layer. Each parameter group contains several parameters (signals), and is uniquely identified by the PGN.
|Transport Protocol| The SAE J1939 transport protocol is used for the segmented transmission of messages with more than 8 bytes of data. The transport protocol is defined in the network layer standard document (SAE J1939/21)
|BAM |Broadcast Announce Message, broadcast variant of SAE J1939 transport protocol
|CMDT |Connection Mode Data Transfer, peer-to-peer variant of SAE J1939 transport protocol
|DA |Destination Address, part of the 29 bit identifier of SAE J1939 messages
|DET| Default Error Tracer, supports development and runtime error reporting
|DMx|Diagnostic messages of the SAE J1939 diagnostics layer
|NAME| Unique 64 bit identifier of each ECU connected to an SAE J1939 network
|PDUF |PDU Format, part of the 29 bit identifier of SAE J1939 messages which identifies the message and determines the layout of the 29 bit identifier
|PDUS |PDU Specific, part of the 29 bit identifier of SAE J1939 messages which identifies broadcast messages which do not have a destination address
|PG| Parameter Group, SAE J1939 term for a specific message layout, corresponds to an N-SDU of J1939Tp
|PGN |Parameter Group Number, unique identifier of an SAE J1939 parameter group
|SA |Source Address, part of the 29 bit identifier of SAE J1939 messages
|SPN |Suspect Parameter Number, unique identifier of an SAE J1939 parameter
|TP.CM |Connection Management message (PGN 00EC00) used by SAE J1939 transport protocol, corresponds to an N-PDU of J1939Tp
|TP.CM_BAM| Broadcast Announce Message, variant of TP.CM that initiates a BAM transmission
|TP.CM_CTS| Connection Mode Clear To Send, variant of TP.CM that is used for handshake during CMDT transmission
|TP.CM_EndOfMsg Ack|End Of Message Acknowledge, variant of TP.CM that acknowledges correct reception of a CMDT transmission
|TP.CM_RTS |Connection Mode Request To Send, variant of TP.CM that initiates a CMDT transmission
|TP.Conn_Abort |Connection Abort, variant of TP.CM that terminates a CMDT transmission
|TP.DT| Data Transfer message (PGN 00EB00) used by SAE J1939 transport protocol, corresponds to an N-PDU of J1939Tp
