    Abstract: A controller includes circuitry configured to: receive global time data indicating a global time associated with an external global clock; synchronize an internal controller clock of the controller with the global clock based on the global time; set a controller time based on the synchronized controller clock; and transmit controller time data indicating the controller time to at least one local device through periodic communication.

    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 robot system includes a robot, a control circuit, a first wireless circuit, a second wireless circuit, and a teaching circuit. The first wireless circuit is connected to the control circuit. The teaching circuit is connected to the second wireless circuit to control the robot via the second wireless circuit, the first wireless circuit and the control circuit. The second wireless circuit is configured to transmit a control signal to the first wireless circuit with a first wireless communication scheme using frequency hopping, the robot being configured to be driven or not to be driven according to the control signal, and transmit an information signal to the first wireless circuit with a second wireless communication scheme in which a signal is transmitted in a case where a wireless resource is determined to be available, the information signal relating to driving of the robot.

    Abstract: A motor control system includes first processing circuitry that controls a motor. An upper-level communication path connects an upper-level communication port of the first processing circuitry to second processing circuitry that sends an instruction to the first processing circuitry via the upper-level communication path. A lower-level communication path connects a lower-level communication port of the first processing circuitry to a plurality of devices connected in series to each other. The devices include rotational angle detection circuitry and output circuitry. The rotational angle detection circuitry detects a rotation angle of the motor. The output circuitry outputs associated information that is associated with the motor and is different from the rotational angle or that is associated with an industrial device associated with the motor. The first processing circuitry performs a predetermined processing based on the rotational angle and the associated information, and sends a result of the predetermined processing to the second processing circuitry.
