  • Publication number: 20240402687
    Abstract: A controlling system includes a network line that communicably connects two controllers to each other. A controlling unit of a first controller executes a packet generating process in which a single packet that begins to be repeatedly transmitted at a first cycle is generated from first data and second data is divided to generate a plurality of packets that begin to be transmitted at a second cycle, and a packet transmitting process in which the single packet and the plurality of packets are transmitted to a second controller via the network line. In the packet transmitting process, the single packet is transmitted in preference to the plurality of packets, and a size of each of the plurality of packets is determined based on the first cycle and a transfer rate of the network line.

  • Publication number: 20230008667
    Abstract: A controller includes: a communication port and a connection port that allow communication with another controller; and a hardware processor coupled to the ports. The hardware processor is configured to: transmit a first state signal indicating a state of the controller of an own device to the other controller from each port; receive a second state signal indicating a state of the other controller from the other controller via each of the ports; and switch, when the own device is in a standby state, the own device from the standby state to an operating state, when a breakdown of the other controller indicated by the received second state signal and an unreceived state in which the second state signal is not received for a predetermined time or more from both the communication and connection ports are monitored and at least one of the breakdown and the unreceived state is detected.
