  • Publication number: 20250055723
    Abstract: The control apparatus includes a communicator that performs, in a communication cycle, in each of a plurality of time segments included in the communication cycle, a type of communication that corresponds to the time segment, a measurer that measures a control time taken for controlling the control target device when a first type of communication is performed independently of the plurality of time segments, and a time slot setter that, when a size of communication data transmitted or received to control the control target device in the first type of communication is smaller than a transmission capacity of data in a time segment that is included in the plurality of time segments included in the communication cycle included in the control time and that corresponds to the first type, shortens a length of the time segment corresponding to the first type from a current setting value.

  • Patent number: 11340954
    Abstract: A control device (1) includes a master-information processing unit (10), and a slave-information processing unit (20) including an information processing CPU (220) that performs information processing through a general-purpose OS, and a distribution control CPU (210) that measures an operating state of the information processing CPU (220) through a real-time OS. The master-information processing unit (10) acquires, from the slave-information processing unit (20), information indicating the operating state of the information processing CPU (220) in the slave-information processing unit (20), determines, based on the acquired information, whether to request the slave-information processing unit (20) to perform information processing, and transmits, when determining to request the slave-information processing unit (20) to perform the information processing, a signal requesting the information processing to the slave-information processing unit (20).
