    Abstract: A controller includes circuitry configured to: synchronize a master clock with an external global clock and set a master time based on the master clock; synchronize a controller clock with the master clock and perform time synchronization to synchronize a controller time based on the controller clock with the master time; transmit controller time data indicating the synchronized controller time to at least one local device; set a plurality of time windows corresponding to a plurality of clock cycles of a clock signal for the time synchronization; determine whether one clock cycle of the plurality of clock cycles has started within one time window of the plurality of time windows, the one time window corresponding to the one clock cycle; and suspend the time synchronization corresponding to the one clock cycle, in response to determining that the one clock cycle has not started within the one time window.

    Abstract: The machine control system includes: a machine configured to execute a motion according to a machine command; a controller server configured to control the machine; and a communication server. The controller server includes control circuitry configured to repeat operations according to a control cycle, the operations including: executing a motion program to generate the machine command for the machine; adding first cycle information designating a first use timing to the machine command; and transmitting the machine command including the first cycle information to the communication server. The machine includes a machine circuitry configured to repeat local operations for controlling the machine according to a local control cycle. The machine circuitry is further configured to: store the machine command received from the communication server; and call the stored machine command, based on the first cycle information added to the stored machine command, to use the machine command in the local control cycle corresponding to the first use timing.

    Abstract: A machine control system includes: a machine configured to execute a motion according to a machine command; and one or more servers configured to control the machine. The one or more servers include control circuitry configured to: repeat an execution of a motion program to generate the machine command for the machine; add first cycle information designating a first use timing to the machine command; and transmit the machine command including the first cycle information to the machine via a communication network. The machine includes a machine circuitry configured to: repeat a local processing for controlling the machine according to a machine control cycle; receive the machine command from the one or more servers; store the received machine command; and call the stored machine command, based on the first cycle information added to the stored machine command, to use the machine command in the local processing corresponding to the first use timing.

    Abstract: A sensor includes an upper-level connection port, a lower-level connection port, a command receiver, a wait time period setter, and a motor-related information obtainer. The upper-level connection port is configured to communicate with an upper-level sensor or an upper-level controller. The lower-level connection port is configured to communicate with a lower-level sensor. The command receiver is configured to receive a command from the upper-level controller. The wait time period setter is configured to set a wait time period based on an order of connection of at least the upper-level sensor or the upper-level controller, the sensor, and the lower-level sensor. The motor-related information obtainer is configured to obtain motor-related information, which relates to a motor, at a timing determined by the command and at a timing based on the wait time period.

    Abstract translation: 传感器包括上级连接端口，下级连接端口，命令接收器，等待时间段设定器和与电机相关的信息获取器。 上级连接端口被配置为与上级传感器或上级控制器进行通信。 下级连接端口配置为与较低级别的传感器通信。 命令接收器配置为从上级控制器接收命令。 等待时间段设定器被配置为基于至少上级传感器或上位控制器，传感器和下级传感器的连接顺序来设置等待时间段。 电动机相关信息获取器被配置为在由该命令确定的定时和基于等待时间段的定时获得与电动机有关的电动机相关信息。
