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.

A control system includes a control unit, a transmission unit, an application execution unit, and an arbitration unit that arbitrates a data set exchanged between the transmission unit and the application execution unit. The arbitration means includes a first acquisition unit that acquires information about pieces of process data managed by the control unit, a second acquisition unit that acquires information about an application executed by the application execution unit, a determination unit that determines process data to be included in a data set based on the information about the pieces of process data acquired by the first acquisition unit and the information about the application executed acquired by the second acquisition unit, and a notification unit that notifies each of the transmission unit and the application execution unit of a content of the process data to be included in the data set determined by the determination unit.

Control system, relay device, and relay program

An object is to provide a function of managing data exchanged with an external device. A control device defines a publishing setting of a process value in accordance with information on one or both of an execution result of a control program and an operating state of the control device. The control device exchanges a data set including a part of one or more process values with the external device in accordance with the defined publishing setting.

Control device, recording medium storing management program, and control system

A control system includes a controller, a transmission unit, an application executing unit, and a management unit. The controller executes a control program controlling a control target, and manages pieces of process data referred to or updated in the control program. The transmission unit transmits data sets including values of the pieces of process data managed by the controller, each of the data sets including one or more process data values. The application execution unit executes one or more applications using the value of the process data included in the data set transmitted by the transmission unit. The management unit determines a data set validating transmission in the data sets transmittable by the transmission unit according to the application executed by the application execution unit.

A safe system is able to execute remote maintenance reliably with respect to a process execution unit for executing a safety control in accordance with a safety program. This safety system includes: a process execution unit for executing a safety control in accordance with a safety program; a communication unit that is directly connected to the process execution unit and mediates external access to a safety program held in the process execution unit; and a support device that is connected via a network to the communication unit and, in accordance with a user operation, executes maintenance, including an addition or a change, with respect to the safety program. The support device and the communication unit identify each other by means of information that has been exchanged in advance, and exchange data required for maintenance.

Safety system and maintenance method

The present invention addresses the novel problem of protecting against threats that can arise as a result of the development of networked or intelligent control devices and control systems. This controller system includes: a control unit that executes a control operation for controlling a control target; and a security unit that is connected to the control unit and oversees and manages security functions for the controller system. The security unit includes a detection means that detects whether any unauthorized intrusion into the controller system has occurred. The control unit includes a command transmission means that transmits commands for changing the behavior of the detection means of the security unit.

Controller system

A support device is connected to a controller system that controls a control target. The controller system can execute an incident response operation of changing a behavior in accordance with an incident that may occur in the controller system. The support device includes a selection module and a setting module. The selection module receives selection of a facility type corresponding to the control target among plural facility types which is preset. The setting module reflects a response rule corresponding to the selected facility type in the controller system by referring to a response rule that is prepared in advance for each of the facility types and defines a behavior for an incident.
