CANoe.J1939, Version 7.6 Development, Simulation and Test of J1939 and NMEA 2000® Systems Since the SAE J1939 specification is the basis for other networks such as NMEA 2000, ISO 11783, ISO 11992 (Truck & Trailer), and FMS (Fleet Management System), the Option can be used in those applications as well. When used in parallel with the .J1939 and .CANopen Options, CANoe is the ideal development and test envi-ronment SAE J1939 is a communication protocol based on CAN for real-time data exchange between control units in the area of commer-cial vehicles. It originates from the international Society of Auto-motive Engineers (SAE) and operates on the physical layer with high-speed CAN per ISO 11898. J1939 is a multimaster system with decentralized network management and primarily connec-tion- for the CiA DS-413 CANopen Truck Gateway. In combina-tion with the .J1587 Option it offers a uniform approach to sys-tems that extend across bus boundaries with a common time less communication. Features and Advantages Using CANoe.J1939 from the very beginning allows the developer to use the same tool through the entire development process, from planning to realization. The models created in the design phase and checked by simulation are continually reused in other forms. It is possible to use the models to verify the implementa-tion base. Functions CANoe.J1939 expands the standard functionality of CANoe with: > Support of the transport protocols BAM, CMDT and Fast Packet (NMEA 2000®) > Graphic display of the network nodes (scanner) > Protocol-specific display, checks, interpretation, filters and search functions in the Trace Window > J1939 Filter Block > Rapid simulation of ECUs > Expanded database > Diagnostic Trouble Code Monitor (DTC Monitor) > OBD Inspection and Maintenance Monitor > Diagnostic Memory Window > J1939 XML Test Module Manager > GNSS Simulator and GNSS Monitor These functions will be described in detail below. 3/22 and later for functional end-of-line testing. It is not necessary for the user to become familiar with the J1939 protocol, instead concentrate on the actual task of creating a sim-ulation or data analysis. This significantly increases the quality of the development process and the efficiency of data analysis. Application Areas Because of its simulation capabilities, CANoe.J1939 is well-suited to the development, design and verification of J1939 networks. Its practical application as a diagnostic and debugging tool is just as feasible as its use in simulating the rest of the bus during startup or assembly. Especially the J1939 XML Test Module Manager sup-ports the user in preparing integration and module tests. CANoe’s analysis and simulation properties are extended by J1939-specific functions, e.g. display of the J1939 protocol in the Trace Window and a network overview in the Scanner.
