Abstract考虑到单网段WorldFIP现场总线系统中远程周期信息不仅具有时间约束而且具有次序约束,通过调整释放时间和截止期来考虑和描述它们的通信次序约束,提出了一种简单、有效的基于启发式的WorldFIP扫描变量表的构建算法,并进行了优化,以保证远程周期信息的时间约束和提非高周期信息的网络性能指标。
Other AbstractIn a single segment WorldFIP system, the remote periodic messages not only have time constraints but also often have precedence constrains. The precedence constrains are considered and described by modifying release time and deadline, a simple and effective heuristic algorithm used to build and optimize WorldFIP Scan Variable table is proposed, in order to meet the time constraints of all remote periodic messages and improve the performance of aperiodic message transfers.
