摘 要:正The communication tasks of fieldbus system often include the information transfer among the field devices. However,fieldbus is not an absolute system,which is a component of entire ***,as to fieldbus scheduling,not only the communication tasks of fieldbus but also the restrains from the other tasks in the system should be *** this paper,a dynamic fieldbus scheduling algorithm is used to cope with the dynamic scheduling of the task system including cyclic real-time tasks,acyclic real-time tasks,non-real-time tasks and time slot tasks under distributed multi-processor *** model of the task system is presented and the algorithm is *** last,a real-time communication scheduling of computer numerical control(CNC) fieldbus system is illustrated to apply the algorithm,and the time and space cost of this algorithm is analyzed.
