CAN Bus on ExoMars

This paper focuses on the implementation of CAN Bus for the EXOMars project, both on the technical aspects of the physical layer, the CAN protocol, and the higher layer protocol, and on the methodology aspects related to the procurement of multiple heterogeneous units, which need to provide a standard interface to the CAN Bus. We will present the ExoMars tailoring and technical choices using the current draft of the CAN ECSS-E50- xx-v2_1 ([5]), and we will present our conclusions regarding the use of CANopen and the draft standard. The Exomars project has successfully applied the previous efforts of CAN WG, and has established a clear implementation methodology that will provide very useful inputs for the finalization of the ECSS standardization process within next year.
