    • Disclosed is a field device which constitutes a plurality of distributed systems to perform a data communication with another field device on a network. The field device includes: an application execution section to execute a distributed application based on each distributed system; a storage section to store setting information on virtual communication addresses allocated to each field device constituting the plurality of distributed systems for each distributed system; and a control section to determine whether a requested data communication is in a same distributed system based on the stored setting information on the virtual communication addresses when the data communication is requested by the application execution section. If the data communication is in the same distributed system, the control section notifies a management section of a virtual communication address of a destination device, and requests the management section to perform the data communication with the destination device.
    • 公开了一种现场设备,其构成用于与网络上的另一个现场设备进行数据通信的多个分布式系统。 现场设备包括:应用执行部分,用于基于每个分布式系统执行分布式应用; 存储部分,用于存储分配给每个分布式系统的构成多个分散式系统的每个现场设备的虚拟通信地址的设置信息; 以及控制部分,用于当应用执行部件请求数据通信时,基于存储的关于虚拟通信地址的设置信息来确定所请求的数据通信是否处于相同的分布式系统中。 如果数据通信在相同的分布式系统中,则控制部分通知管理部分目的设备的虚拟通信地址,并请求管理部分与目的设备进行数据通信。

    • The allocation of hardware resources to distribution applications is enabled without using effective task priority available only in field devices. A distribution system makes a plurality of field devices connected with each other through a network (N) operate a plurality of distribution applications (distribution AP) in parallel. The distribution system is provided with an importance adjustment unit (3) that calculates relative values indicative of the task priority in the field devices in accordance with the importance of the distribution AP designated for every distribution AP and a resource allocation unit (13) that allocates the hardware resources of each field device to each of the tasks of which the distribution AP are composed in accordance with the relative values in the field devices calculated by importance adjustment unit (3).
    • 启用硬件资源到分发应用程序的分配,而无需使用仅在现场设备中可用的有效任务优先级。 分配系统通过网络(N)并行地操作多个分发应用(分配AP)使得多个现场设备相互连接。 分配系统具有重要度调整单元(3),其根据为每个分配AP指定的分配AP的重要性和分配了资源分配单元(13)来计算表示现场设备中的任务优先级的相对值 根据重要性调整单元(3)计算出的现场设备中的相对值,将每个现场设备的硬件资源分配给分配AP的每个任务。
