Provided is a technology with which it is possible to access a function unit to be accessed without ascertaining an IP address of the function unit. Provided is a unit comprising: a communication unit for relaying a communication between an external device connected to a first network and another unit connected to a second network; a setting unit for acquiring address information of the other unit in the second network from the other unit and generating setting information in which the address information is associated with an identifier which substitutes for the address information; and a link information generation unit for generating, on the basis of the identifier, link information used to access information on the other unit from the external device.

In a master device (control device) that employs a configuration list, setup change is performed easily without requiring a complicated operation with respect to a partial change in the configuration of a slave-side system on a slave side. A control unit (11) of a control device (10) is configured to perform communication for inquiring about device information to an address in an active configuration list through a communication unit (12), and determine to be abnormal when the result of the communication with respect to a common portion of a slave-side system (20) is different from the device information in the active configuration list.

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.

A control system includes a first control device and a second control device. The first control device can control a control target. The first control device includes a first control unit, a first communication unit, a first monitoring unit, and a first determination unit. The first control unit can control the control target. The first communication unit can communicate with the control target. The first monitoring unit monitors communication between the second control device and the control target. The first determination unit determines execution or standby of control of the control target by the first control unit on the basis of a monitoring result of the first monitoring unit. The second control device includes a second control unit and a second communication unit. The second control unit can control the control target. The second communication unit can communicate with the control target.

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.

A control system includes a control device, an information processing device, a grouper, and a generator. The control device executes a control program controlling a control target while managing process data of the control program. The control device transmits one or more types of data sets storing a part of the process data according to a communication setting. The information processing device executes one or more applications using the process data by using the one or more types of data sets. The grouper allocates the process data designated to be used in the one or more applications to one or more groups. The generator generates the communication setting for the control device such that the process data allocated to the group are stored in one data set and transmitted for each of the groups grouped by the grouper according to an allocation result.

The present disclosure is directed to systems, methods and devices for facilitating object-based cross-domain industrial automation control. An object library comprising a plurality of objects may be maintained. One or more of the objects may represent physical counterparts for use in an industrial automation process. Each object of the plurality of objects in the object library may have at least one property that an automated control device operation can be programmed to act on. Each object of the plurality of objects may also have at least one property that a human machine interface component can utilize in generating display elements corresponding to the objects for display on the human machine interface. When modifications to objects in the object library are received, those modifications may be automatically deployed and incorporated in controller logic and HMI graphics and control.

A communication method between a master and a device, the master transmits in a subcycle a received condition message (RCM) for an immediately prior subcycle, wherein the RCM is an ACK when a transmission from the device in the preceding subcycle was correctly received and the RCM is a NACK when a transmission from the device in the preceding subcycle was not correctly received, comprising: including in each transmitted condition message a current priority data acknowledgement flag (CPDAF), the CPDAF being transmitted set in each condition message for each subcycle of an offset cycle after the master correctly received in a current cycle a priority data message, the offset cycle being defined as the second and subsequent subcycles of a current cycle and the first subcycle of a next cycle, the CPDAF being transmitted as cleared otherwise.

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). The information processing CPU (220) in the slave-information processing unit (20) performs the information processing upon receiving the signal requesting the information processing.
