CANOPEN ON RASTA: THE INTEGRATION OF THE CANOPEN IP CORE IN THE AVIONICS TESTBED

摘要

This paper presents the work done within the ESA EstecData Systems Division, targeting the integration ofthe CanOpen IP Core with the existing Reference ArchitectureTest-bed for Avionics (RASTA). RASTA is thereference testbed system of the ESA Avionics Lab, designedto integrate the main elements of a typical DataHandling system. It aims at simulating a scenario wherea Mission Control Center communicates with on-boardcomputers and systems through a TM/TC link, thus providingthe data management through qualified processorsand interfaces such as Leon2 core processors, CANbus controllers, MIL-STD-1553 and SpaceWire. Thisactivity aims at the extension of the RASTA with twoboards equipped with HurriCANe controller, acting asCANOpen slaves. CANOpen software modules havebeen ported on the RASTA system I/O boards equippedwith Gaisler GR-CAN controller and acts as master communicatingwith the CCIPC boards. CanOpen servesas upper application layer for based on CAN definedwithin the CAN-in-Automation standard and can be regardedas the definitive standard for the implementationof CAN-based systems solutions. The development andintegration of CCIPC performed by SITAEL S.p.A., isthe first application that aims to bring the CANOpen standardfor space applications. The definition of CANOpenwithin the European Cooperation for Space Standardization(ECSS) is under development.
