CANalyzer.J1939, Version 7.6 Comprehensive ECU and Network Analysis for J1939 and NMEA2000® Users Functions CANalyzer.J1939 expands the standard functionality of the CANalyzer with: > Protocol-specific display, checks, interpretation, filters and search functions in the Trace Window > Support for the BAM , CMDT and Fast Packet (NMEA 2000®) transport protocols > Graphic display of the network nodes (scanner) > J1939 Filter Block > Expanded database > Expanded Generator Block > J1939-specific programming functional properties in CAPL > Diagnostic Trouble Code Monitor (DTC Monitor) > Diagnostic Memory Window > OBD Inspection and Maintenance Monitor > GNSS-Simulator and GNSS-Monitor These functions will be described in detail below. SAE J1939 is a communication protocol based on CAN for the data exchange between control units in the area of commercial vehi-cles. It originates from the international Society of Automotive Engineers (SAE) and operates on the physical layer with high-speed CAN per ISO11898. J1939 is a multimaster system with decentralized network management and primarily connection-less communication. Features and Advantages In addition to CANalyzer’s high-performance functionality, the J1939 extension gives the user a tool that can be used from initial development to production of a J1939 project. The J1939-specific extension allows the user to concentrate on the actual tasks of data analysis without detailed knowledge of the J1939 protocol. This significantly increases the efficiency of data analysis. Misin-terpretations 3/46 of CAN frames are avoided. Application Areas CANalyzer.J1939 can be used wherever J1939 networks are devel-oped, diagnosed, and tested. Networks can also be simulated to a limited extent. CANalyzer.J1939 can be used to monitor and debug other J1939 networks, since the SAE J1939 specification is the basis for NMEA 2000, ISO 11783, ISO 11992 (Truck & Trailer), and FMS (Fleet Management System) networks. In combination with the .J1587 Option it offers a uniform approach to systems that extend across bus boundaries with a common time base. CANalyzer’s analysis properties are being extended with J1939-specific features, e.g. new functions for displaying the J1939 protocol in the Trace Window and the addition of the J1939 Filter Block.
