    • Embodiments relate to two general purpose computers connected in a peer-to-peer mode by connecting a cable (or wireless connection) between universal ports (e.g., PCIe ports) on each computer. A timing protocol utility runs on each computer to time schedule operations performed by its respective computer. Because the system clocks on each peer computer operate independently (asynchronously), they may vary somewhat from each other. To support time synchronized peer-to-peer operations, paired clock value (one for each peer computer) are generated continually and independently by each peer system. Each peer system periodically supplies the paired clock values to its associated timing protocol utility, which uses the paired clock values to time synchronize peer-to-peer computer operations. The timing protocol utilities may also exchange the paired clock values with each other for integrity checking and other operations.
    • 实施例涉及通过在每个计算机上的通用端口(例如,PCIe端口)之间连接电缆(或无线连接)而以对等模式连接的两个通用计算机。 定时协议实用程序在每个计算机上运行,​​以便由其相应的计算机执行时间调度操作。 由于每个对等计算机上的系统时钟独立运行(异步),它们可能会有所不同。 为了支持时间同步的对等操作,配对的时钟值(每个对等计算机一个)由每个对等系统连续且独立地生成。 每个对等系统周期性地将配对的时钟值提供给其关联的定时协议实用程序,其使用成对的时钟值来时间同步对等计算机操作。 定时协议实用程序还可以将配对的时钟值彼此交换,以进行完整性检查和其他操作。

    • A control system includes: a master station including a PLC executing user program; and a remote station including a communication memory to which a PLC device is assigned, a slave communication unit, and a unit to or from which one or more pieces of data is input or output, and being connected to the master station through a network. The PLC transmits, to the slave communication unit, assignment object designation information designating an object that is among unit data input or output to or from the unit and to which a PLC device is assigned, and an assignment rule. The slave communication unit assigns unit data that is among unit data input or output to or from the unit and is designated by the received assignment object designation information to the communication memory based on the received assignment rule.
    • 控制系统包括:主站,包括执行用户程序的PLC; 以及远程站,包括分配了PLC设备的通信存储器,从通信单元以及从其输入或输出一个或多个数据的单元或从其传送的单元,并通过网络连接到主站。 PLC向从属通信单元向从属通信单元发送指定对象的分配对象指定信息,分配对象指定信息是从单元输入或输出到单元并且被分配了PLC设备的单元数据和分配规则。 从通信单元根据接收到的分配规则,将输入或输出到单元的单元数据中的单元数据分配给接收到的分配对象指定信息给通信存储器。
