7 SAE J1939 interface

The inclination sensors have a standardised SAEJ1939 interface� All measured values and parameter groups can be accessed via the J1939 protocol� The individual configuration can be saved in the internal permanent memory (flash)�

7.1 Overview and structure of the SAE J1939 protocol

SAE J1939 uses 29-bit CAN identifier (extended frame format CAN 2�0B)� An SAE J1939 message has the following structure:

7.1.1 PDU format 1

This format defines a message which is sent to a defined unit� In this case the PDU-specific byte (PS) is the target address (DA) of the unit� If the value of the PDU format field (PF) is between 0x00 and 0xEF, it is a PDU format 1 message�
For proprietary (manufacturer-specific) messages the PDU format value 0xEF is defined� Ext� data page bit = 0 and data page bit = 0�

7.1.2 PDU format 2

This format defines a message which is sent globally� In this case the PDU­specific byte (PS) corresponds to the group extension (GE)� If the value of the PDU format field (PF) is between 0xF0 and 0xFF, it is a PDU format 1 message�
For proprietary (manufacturer-specific) messages the area (PDU format PF) and group extension (GE) 0xFF00 – 0xFFFF is defined� Ext� data page bit = 0 and data page bit = 0
