RTI LIN MultiMessage 模块组

将 dSPACE 系统与 LIN 通信网络相结合

RTI LIN MultiMessage 模块组是实时接口的扩展,可用于将 dSPACE 系统与 LIN 通信网络结合在一起,并能配置这些 LIN 网络。


RTI LIN MultiMessage Blockset是Real-Time Interface (RTI)的扩展,可以将 dSPACE 系统与 LIN 通信网络结合在一起,并能配置这些 LIN 网络。它与Simulink ® 完全集成,支持各种dSPACE产品,如SCALEXIO、PHS系统和MicroAutoBox II。


RTI LIN MultiMessage Blockset模块组的优势在于处理复杂的 LIN 设置,从而可利用单个 Simulink ® 模块(通过数据库文件进行配置)控制并配置所有的无条件 LIN 帧和事件触发型 LIN 帧。LIN 配置可以从通信矩阵描述文件(例如 LDF、DBC、FIBEX 和 ARXML等)中轻松读入。

我们建议不要在新的SCALEXIO项目中使用 RTI LIN MultiMessage Blockset。对于新项目,我们建议使用 Bus Manager 其具有广泛功能。

1) RTI LIN MultiMessage Blockset将从2024年11月15日(终止日期)起不再支持SCALEXIO。这些模块集将继续支持MicroAutoBox II和MicroLabBox等其它平台。

您可以在2023年5月15日(含)之前购买此产品,用于SCALEXIO平台。在2024年11月15日之前,持有软件维护服务合同的客户仍然可以获得RTI LIN MultiMessage Blockset 的新版本。dSPACE 2024-B版将是支持这些模块集和SCALEXIO的最后一个版本。

RTI LIN MultiMessage Blockset的用例已经得到后续产品Bus Manager的支持。Bus Manager具有诸多优点。我们的网站上提供了迁移支持信息和工具(例如迁移脚本)。

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)
  • Importing AUTOSAR description (ARXML) files 1)
  • Importing database container (DBC) files
  • Importing FIBEX (ASAM MCD-2 NET) files 1)
  • 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 n 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
