RTI LIN MultiMessage Blocksetは、Real-Time Interfaceの拡張で、dSPACEシステムをLIN通信ネットワークと組み合わせたり、LINネットワークを設定したりするために使用できます。Simulink®と完全に統合されており、SCALEXIO、PHSシステム、MicroAutoBox IIなどのさまざまなdSPACE製品をサポートしています。


RTI LIN MultiMessage Blocksetの利点は、LINの複雑な設定を操作するところにあります。すべての条件非依存およびイベントトリガLINフレームを単一のSimulinkブロックから制御し設定できます(データベースファイルを介した設定)。LIN設定はLDF、DBC、FIBEXおよびARXMLなどの通信マトリクス記述ファイルから読み込むことができます。

The latest dSPACE bus configuration software, the Bus Manager, combines a multitude of functionalities in one tool, including all the important functions of the RTI LIN MultiMessage Blockset.

Functionality Description
  • Database-file-oriented Simulink blockset for combining dSPACE systems with LIN communication networks and for configuring these LIN networks
  • One Simulink block per bus configuration
Signal initialization/configuration
  • Importing LDF (LIN Database Files), support of LIN standard 1.3, 2.0, 2.1, 2.2
  • Importing AUTOSAR description files (*.arxml)
  • Importing database container (DBC) files
  • Importing FIBEX (ASAM MCD-2 NET) files
  • Specifying baud rate, transceiver type, terminating resistors, etc.
  • Switching between several schedules defined in LDF file
  • Generating LIN schedules (list of grouped frames defined in LDF file)
Node configuration
  • Configurable LIN network serial number
  • Enabling/disabling automatic configuration
  • Manipulation option: Node enable/disable overwrites automatic configuration
  • Support of configured and preconfigured slave nodes
  • Master request and slave response frames also usable in model during automatic node configuration
  • Slave: Conditional change NAD Service
  • Slave: Read by Identifier Service
  • Setting receive and transmit messages
  • Encoding input signals from the Simulink model as raw data and transmitting the raw data to the LIN bus
  • Decoding raw data and providing physical signals as outputs
  • Manipulating raw data, for example, using checksums, toggling bits, inserting parity bits
  • Support of event-triggered frames
  • Changing frame length during run time and dynamically
  • Special run-time frame manipulation features: suppress response for
  • frames, corrupt LIN frame checksum for n frames
  • Capturing frames not defined in LDF file or model
  • Online switching between raw and signal data inputs
  • Special signal generation: counter, in-data user checksum
Bus events
  • Energy-saving modes (sleep/wake-up)
  • Sending wake-up and sleep requests
  • Schedule is always restarted with first frame in schedule
  • Fixed response time, manipulation of baud rate, break length, break delimiter, and LIN frame checksum
  • No interrupt support
LIN slave tasks
  • Classic or enhanced checksum
  • Unconditional frames
  • Event-triggered frames
LIN master tasks
  • Sending wake-up and sleep commands
  • Diagnostic frames (no diagnostic commands supported)
  • Go-to-sleep without sending sleep command
Further manipulation options
  • Online source switch for each signal: input, counter, constant, signal error value (for manual and automated tests)
  • Enable saturation of signal-in ports
Handling characteristics
  • Graphical “one-for-all” configuration interface
  • Interface to Simulink via bus selectors
  • User defined, automatically generated mapping
  • Generation of Simulink input ports for unmapped signals
  • Generation of frame-based ControlDesk layouts with Bus Navigator
