J1939 Interface Description

5.1

J1939 Message Format

The J1939 interface uses the 29 bit CAN-ID. The CAN-ID in J1939 is assembled of a 

Parameter Group Number (PGN) and a source address.
A parameter group (PG) consists of various parameters, such as offset value, direction of 

rotation, etc. That means, a PGN specifies what

’

s in that data field.

The priority field has a width of 3 bits. It indicates the message priority. Priority "0" is the highest 

and "7" the lowest.
A value of "PDU format" between 0x00 and 0xF0 causes messaging between two specific 

devices. In this case the field "PDU specific" equates to the destination address. A value of 

"PDU format" higher than 0xF0 causes broadcast messaging to all devices in a group. "PDU 

specific" is then interpreted as a "group extension".
The device address (node ID) of every individual device in the network has to be unique. This 

can be assured by means of the address claiming procedure. Details see chapter "J1939 

Interface Description", section "Address claiming".

5.2

Interpretation of the CAN Identifier

The CAN identifier of a J1939 message contains Parameter Group Number (PGN), source 

address, priority, data page bit, extended data page bit and a target address (except for 

broadcast messages).
The identifier is composed as follows:

The entire telegram contains the identifier and the data section.
