  • Patent number: 10924406
    Abstract: A control device includes a cyclic communication part and a communication management part. A cyclic communication part controls communication of first control data of which arrival in a first guarantee time is guaranteed according to a preset cyclic period and second control data of which arrival in a second guarantee time longer than the cyclic period is guaranteed and of which a sequence of information included is determined. The communication management part manages a communication schedule of first control data and second control data. When new second control data is acquired while the second control data is divided into a plurality of communication data and communicated according to the cyclic period, the communication management part determines a communication sequence of the plurality of second control data according to priorities of the plurality of second control data.

  • Patent number: 10735520
    Abstract: A control device includes a cyclic communication part, a message communication part, and a communication management part. The cyclic communication part performs communication according to a preset cyclic period. The message communication part performs communication that need not conform to the cyclic period. The communication management part manages a communication schedule for the cyclic communication part and the message communication part. When it is detected that control data scheduled to be communicated is data for preferentially selecting communication in the cyclic communication part, the communication management part detects a communication state of the cyclic communication part. When cyclic communication is possible, the communication management part stores the control data in the cyclic communication part, and when cyclic communication is not possible, the communication management part stores the control data in the message communication part.

  • Publication number: 20190250593
    Abstract: A slave device, a control system, a communication method for response data and a recording medium, through which even when a high-urgency response request is obtained during communication of large-capacity data which requires a plurality of cyclic periods, response data corresponding to the high-urgency response request can be communicated quickly, are provided. The slave device includes a cyclic communication portion and a communication management portion. The cyclic communication portion communicates in accordance with pre-set cyclic periods. The communication management portion manages communication of response data corresponding to a response request from a control device. If a request of response data with high priority is received during communication of response data with low priority over a plurality of cyclic periods, the communication management portion temporarily interrupts the communication of the response data with low priority to communicate the response data with high priority.

  • Patent number: 9680691
    Abstract: A technique is provided for detecting a connection abnormality of a slave device, in a network system including a master device and slave devices. The technique includes a connection abnormality detection method in a network system including a master device and a plurality of slave devices. In the network system, data is transmitted from the master device and then returned to the master device through respective slave devices. Each slave device has an upstream-side port and a downstream-side port. The connection abnormality detection method includes acquiring topology information of the network system, closing or opening the port of each slave device such that a serial topology is formed to include a target slave device located on the downmost stream side, transmitting inspection data after the control of the port, and detecting a connection abnormality of the device on the basis of a status of return of the inspection data.
