Interface to MIL-STD-1553

Interface to MIL-STD-1553 networks

  • Connects a modular dSPACE real-time system to a MIL-STD-1553 network
  • For hardware-in-the-loop simulation and rapid control prototyping
  • Supports MIL-STD-1553B
  • Comprehensive Simulink Blockset

Application Areas
The interface to MIL-STD-1553 Interface Board connects a modular dSPACE real-time system to a MIL-STD-1553 network. Its application areas are hardware-in-the-loop (HIL) simulation and rapid control prototyping (RCP) for testing and developing control systems that utilize MIL-STD-1553. Examples are HIL simulation for satellite avionics integration testing and component validation for aircraft flight surface actuator and engine controllers or FADECs. This interface is based on the industry-proven QPC-1553 module from GE Intelligent Platforms.

Key Benefits
The interface to MIL-STD-1553 Interface Board enables you to interface your MIL-STD-1553 network directly to the real-time application running on the dSPACE processor board. It supports the DS1005 PPC Board and DS1006 Processor Board and is also multiprocessor-capable. Each channel can be configured independently as a remote terminal (RT), bus controller (BC), or bus monitor (BM). As a remote terminal, each channel supports up to 31 remote terminals, and in BC functionality schedule lists are supported, with the ability to change lists dynamically during run time to facilitate fault testing of RTs.

Hardware and Software
The interface MIL-STD-1553 Interface Board is based on the DS4504 PMC Carrier Board, which acts as a carrier for an ETX (Embedded Technology eXtended) module and a MIL-STD-1553 PCI Mezzanine Card (PMC). Data exchange between the ETX and the dSPACE processor board runs via the PHS++ (peripheral high-speed) bus and a 2-MByte dual-port memory (DPMEM). A Compact Flash (CF) card contains the QNX run-time operating system and the ETX application. The I/O connection to the Simulink model is configured graphically by means of the related MIL-STD-1553 Basic Blockset, using S-functions.
