Integrating Inacessibility in Response Time Analysis of CAN Networks
Ref: HURRAY-TR-0004 Publication Date: 6, Sep, 2000Abstract:
Controller Area Network (CAN) is a fieldbus network suitable for
small-scale Distributed Computer Controlled Systems, being appropriate for
transferring short real-time messages. Nevertheless, it must be understood
that the continuity of service is not fully guaranteed, since it may be
disturbed by temporary periods of network inaccessibility. In this paper,
such temporary periods of network inaccessibility are integrated in the
response time analysis of CAN networks. The achieved results emphasise that,
in the presence of temporary periods of network inaccessibility, a CAN
network is not able to provide different integrity levels to the supported
applications, since errors in low priority messages interfere with the
response time of higher priority message streams.
