RTI CAN MultiMessage Blockset

For combining dSPACE systems with CAN communication networks

The RTI CAN MultiMessage Blockset is an extension for Real-Time Interface and can be used for combining dSPACE systems with CAN communication networks and for configuring these CAN networks.

  • Ideal for handling complex CAN setups
  • Convenient configuration of CAN setups and database file import (DBC, FIBEX, AUTOSAR)
  • J1939 support, CAN FD support, Partial networking support

Application Areas

The RTI CAN MultiMessage Blockset is an extension for Real-Time Interface and can be used for combining dSPACE systems with CAN communication networks and for configuring these CAN networks. 

Configuration of CAN interfaces

Working with large hardware-in-the-loop (HIL) systems means working with a considerable volume of CAN messages. Moreover, test environments and database container (DBC, FIBEX, AUTOSAR) files change frequently during the development process. CAN configuration updates in large models and parameter changes can be done with just a few clicks.

Parameters and Messages

Parameters can be accessed directly in ControlDesk® and AutomationDesk via user trace files. The Bus Navigator is also supported for easy handling of CAN configurations, including messages and signal manipulation in ControlDesk. Numerous test cases can be created via flexible manipulation at the message and signal levels. The current value of the signals in messages can be defined. Messages can be transmitted spontaneously (kick-out) and can also be enabled. They can also be transferred directly between two CAN buses, unidirectionally or bidirectionally, via the Gateway block, without message or signal manipulation. The message transmission and signal manipulation option can be changed during run time.

Benefits

The strong point of the RTI CAN Multi Message Blockset is handling complex CAN setups, especially in hardware-in-the-loop applications. You can control, configure, and manipulate a very high number of CAN messages from one single Simulink® block. Not only does handling become very straightforward, but the size of the model files is also reduced. This cuts code generation time and build time. CAN descriptions can easily be read in from communication matrix description files such as database container files (DBC), ASAM-MCD2D (FIBEX), AUTOSAR System Template files or ARXML files. CAN, J1939 formats and also the CAN FD (Flexible Data Rate) protocol with a much higher data rate and an extended payload data length are supported as well. These functions make the RTI CAN MultiMessage Blockset a time-efficient and cost-effective solution for managing complex CAN setups.
