Windows-DLL for the development of J1939
service and test applications

Overview of functions

The J1939 API is a programming interface that allows quick and easy development of J1939 applications on a PC with Windows.
The programming interface is based on the IXXAT VCI driver (Virtual CAN Interface)  and is therefore available for all IXXAT CAN interface cards. Based on the J1939 protocol software from IXXAT, the SAE J1939 API allows complete simulation of J1939 applications on a PC.
Via various interfaces, the languages C/C++ and Python are available to users for programming a J1939 application. Examples of C, C++ and Python are included in the scope of supply of the software.

Based on the J1939 programming interface, several applications can be implemented on one CAN interface, which can also communicated with each other. This allows simulation of complete J1939 networks on one PC and is therefore ideal for testing and commissioning J1939 control units.
Parameters of a message (parameter groups) are interpreted with a configuration file, which can be generated with the configuration program provided. This enables definition of application-specific messages.

 

Functions of the SAE J1939 API

• Transmission and reception of J1939 messages (PGs) with up to 1785 bytes of payload (broadcast announce message, connection mode data transfer)
• Automatic conversion of received messages to parameters and vice versa
• Use of the database from the J1939 configuration program for parameter interpretation
• J1939 plug-and-play functionality via address claiming mechanisms
• Support of several CAN channels and therefore J1939 networks is possible

Hardware requirements

• PC with Windows 2000/XP/Vista
• IXXAT CAN interface card and CAN driver VCI V3
