    • Systems (200, 230, 240) and methods (700) for controlling a simulation of an operation of a Fieldbus system (100) comprising at least one FIM (114, 116) communicatively coupled to field devices (122, 124). The methods involve initiating a current simulation (CS) of an operation of the FIM and/or field devices. The methods also involve obtaining intermediate simulation information (ISI) indicating a status/progress of CS. The methods further involve displaying ISI to a user of a simulation system and displaying visual elements (610, . . . , 620) for controlling the progress of CS to the user. Gantt charts (672, 674) for the FIM/field devices and visual content showing data exchanges between software elements and/or hardware elements of the simulation system can further be displayed to the user. The visual elements can facilitate speeding up CS, slowing down CS, moving the progress of CS backwards/forwards, and/or stopping/re-starting the CS.
    • 用于控制现场总线系统(100)的操作的模拟的系统(200,230,240)和方法(700),包括通信地耦合到现场设备(122,124)的至少一个FIM(114,116)。 该方法涉及启动FIM和/或现场设备的操作的当前模拟(CS)。 该方法还涉及获得指示CS的状态/进展的中间模拟信息(ISI)。 所述方法还包括向模拟系统的用户显示ISI并且显示用于控制用户的CS进度的视觉元素(610,...,620)。 用于FIM /现场设备的甘特图(672,674)和显示模拟系统的软件元件和/或硬件元件之间的数据交换的可视内容可以进一步显示给用户。 视觉元素可以促进CS的加速,CS的减慢,CS的向前/向前的移动进程和/或停止/重新启动CS。

    • Data in a data structure is compressed by exploiting prior knowledge of the format of the data structure. A portion of the data structure is captured. A metadata component is selected for the portion. A data buffer is updated by using the selected metadata component and the captured portion. This compression technique achieves real-time data compression suitable for use with data structures used for the synchronization of the state of communication entities. The compression technique reduces the volume of data to be communicated for the synchronization of the state of communication entities and, therefore, provides faster synchronization. The present technique is suitable for use in redundant systems.
    • 通过利用数据结构格式的先前知识来压缩数据结构中的数据。 数据结构的一部分被捕获。 为该部分选择元数据组件。 通过使用所选择的元数据组件和捕获的部分来更新数据缓冲器。 该压缩技术实现了适用于与用于通信实体状态同步的数据结构相适应的实时数据压缩。 压缩技术减少了要通信的数据量,用于通信实体状态的同步,因此提供更快的同步。 本技术适用于冗余系统。
