A settings information generation device, for reducing the number of settings steps pertaining to a device in a superordinate device that communicates with a slave device to which the device is connected, includes: a selection unit for accepting a selection of a device to be connected; an acquisition unit for acquiring operational settings information including the input/output data length of the selected device; and a generation unit for generating, on the basis of the operational settings information, superordinate device settings information for setting a storage region for storing data exchanged with the device by a controller via a device management unit.

Settings information generation device, settings information generation method, and recording medium

Reliability with which a control device at a transmission destination can receive data is improved. In a communication system in which a plurality of control devices for factory automation are connected to a network, a communication protocol among the control devices includes a publish/subscribe type. Each of the control devices includes: a data storage unit in which control data is stored; a publisher unit that transmits data including a state of the control device of the publisher unit itself to other control devices than the control device; and a subscriber unit that receives data from each of the other control devices. When a state of each of the other control devices that is received by the subscriber unit satisfies a reception allowing condition, the publisher unit transmits the control data of the control device of the publisher unit itself.

Communication system, control device, setting device, setting method, and program

An information processing device includes: a collection unit configured to collect an event log corresponding to an event generated in a control system including at least one network; an extraction and specification unit configured to extract at least one event log corresponding to an event generated arising from an identical factor from the collected event log, and to specify an event log representing the event generated arising from the identical factor in the at least one event log extracted; and an output unit configured to output the event log representing the event generated arising from the identical factor and event logs corresponding to other events generated arising from the identical factor while distinguishing the event log representing the event generated arising from the identical factor and the event logs corresponding to other events generated arising from the identical factor from each other.

Information processing device, information processing program, and information processing method

A device is easily exchanged without changing a program of a controller. A device communication management unit generates digital input data that stores only ON/OFF information of a device in accordance with a copy setting information table set by a user.

Slave device, control method of slave device, non-volatile computer readable recording medium

An information processing device includes: a detection unit configured to detect an event generated in a control system including at least one network; a connection configuration expression unit configured to visually express a physical connection and a logical connection of the network included in the control system; and an event output unit configured to output the event detected by the detection unit while correlating the event with the physical connection and the logical connection of the network, the physical connection and the logical connection being visually expressed according to a place where the event is generated.
