ARINC 717 Interface

Interface to the ARINC717 avionics data bus

  • Connects modular dSPACE real-time systems to the ARINC717 data bus
  • Simulink® block library


Application Areas
The ARINC 717 Interface is used to connect dSPACE simulators and prototyping systems to the ARINC717 avionics data bus. ARINC717 is used in avionics systems to communicate with flight data recorders. It enables dSPACE systems to be integrated with such network communication, a typical example being the HIL simulation of an aircraft for testing avionics in Integrated Flight Testing (ITF) applications. It supports multiple channels and even multiple buses, so control applications can comprise several devices.

Key Benefits

  • Easy configuration of each IP module via a setup block
  • Data manipulation blocks
  • Supports advanced testing by inducing predefined errors in a message
  • Full software support for C handcoded applications


Hardware and Software
The interface consists of the IndustryPack (IP) module carrier board DS4501 and the IP-717-HBP from GE Intelligent Platforms. On the real-time model side, a Simulink block library and S-functions are provided to access the IP module and its receive and transmit channels. The block library provides access to the ARINC717 bus on raw value level, i.e., transmit and receive blocks in the model work with 12-bit ARINC717 data words, with a user-configurable number of words at a specific frequency.
