  • Patent number: 11917024
    Abstract: A control system includes a control device and a device that communicates with the control device. The control system includes a controller that periodically performs a control operation for controlling an object to be controlled, a communication processor that performs communication processing for periodically exchanging data with the device, a providing component that provides a development environment for performing a part of creation of contents of processing performed by the controller and for making of settings involved with communication processing by the communication processor, and a determination module that determines a settable range of a cycle time of exchange of data with the device based on contents set in the development environment.

  • Publication number: 20220163939
    Abstract: A master device manages a plurality of slave devices constituting a network including a ring topology. The plurality of slave devices includes: a first slave device serving as a starting point and a terminal point of the ring topology; and a plurality of second slave devices connected between a first output port of the first slave device and a second output port thereof and constituting the ring topology. On the basis of a network configuration detected when the second output port and the output port of a second slave device paired with the second output port are available and of a network configuration detected when the second output port and the output port paired therewith have been made unavailable, the master device determines an incorrect wiring path between the first output port and the second output port and outputs information indicating the incorrect wiring path to an information processing device.

  • Publication number: 20220147006
    Abstract: A control system includes a control apparatus functioning as a master, and plural slaves which are network-connected to the control apparatus. The slaves each have identification information. The control apparatus includes executes a first instruction to set specified identification information to each of one or more specified slaves. The control apparatus outputs first error information indicating which slave that the setting of the identification information to which is failed, among the one or more specified slaves.

  • Patent number: 10627784
    Abstract: A first control unit includes a data transfer relay unit that executes a process of transferring input data corresponding to a signal input to an input and output unit to a second control unit according to a request from the second control unit, and/or a process of transferring output data that defines a signal to be output from the input and output unit from the second control unit to the input and output unit, a storage unit that holds the data transferred by the data transfer relay unit, and a monitoring processing unit that determines whether or not a predetermined trigger condition has been satisfied on the basis of the data held in the storage unit, and outputs a value of any data held in the storage unit according to a predetermined output configuration when it is determined that the trigger condition has been satisfied.

  • Publication number: 20190197016
    Abstract: A control system and control device are provided capable of flexibly realizing communication processing without requiring an additional unit even when a plurality of units having a communication function are present is provided. The control system includes a first unit having a first communication port for transmitting and receiving data, and one or more second units electrically connected to the first unit. Each of the second units includes a logical communication unit for transmitting/receiving data to/from the device electrically connected to the first communication port of the first unit. The first unit includes a forwarding processing unit which forwards transmission data transmitted from the second unit to the device which is a transmission destination.

  • Patent number: 10274936
    Abstract: Provided is a control apparatus that can, by causing multiple control programs that include motion computation programs to be executed in parallel, shorten the execution cycle of control programs that are executed cyclically. A microprocessor is configured to execute multiple control programs in parallel. When executing communication commands included in control programs that are to be executed in parallel, a scheduling program causes the microprocessor to execute the communication commands such that there is no competition between communication processes in a communication controller.
