ARINC 717 Interface

Interface to the ARINC 717 avionics data bus

With the ARINC 717 Interface, you can connect a dSPACE system to the ARINC 717 avionics data bus. So you can test aircraft electronics and develop new control functions for a wide range of applications in aircraft.

Application Areas

The ARINC 717 Interface is used to connect dSPACE simulators and prototyping systems to the ARINC 717 avionics data bus. ARINC 717 is used in avionics systems to communicate with flight data recorders. With the interface, dSPACE systems can 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. The ARINC 717 Interface 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 applications handcoded in C

Hardware and Software

The interface consists of the DS4501 IP Carrier Board 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 ARINC 717 bus on raw value level, i.e., transmit and receive blocks in the model work with 12-bit ARINC 717 data words, with a user-configurable number of words at a specific frequency.
