Abstract (EN): Many real-time control applications require heterogeneous sets of tasks, where both periodic and sporadic computational activities must be performed. For distributed systems, this implies that also the messages that are exchanged at the fieldbus level are heterogeneous in theirs nature. A flexible real-time communication system should, therefore, efficiently support both event triggered and time-triggered communications. The authors have recently proposed a new CAN-based protocol (FTT-CAN) that supports both event-triggered and time-triggered traffic, with temporal isolation. This paper describes the asynchronous messaging system of FTT-CAN, which handles the event-triggered traffic, supporting different QOS requirements. Furthermore, an enhanced response-time analysis concerning this type of traffic and experimental results are also presented. Copyright (C) 2001 IFAC.
