Abstract: A control device includes: a feature extraction unit that calculates one or more feature amounts from one or more state values; a processing unit that calculates a score based on the one or plurality of feature amounts calculated by the feature extraction unit with reference to a learning model; a determination unit that generates a determination result indicating whether any abnormality has occurred in a monitoring target based on the score; a first data storage unit that stores at least one of data related to processing in the feature extraction unit and data related to processing in the processing unit; a second data storage unit that stores an arbitrary state value capable of being referred to by the control device; and an authority management unit that restricts access to the first data storage unit.

Abstract: This control system includes: a first arithmetic unit for doing cyclic execution of a first task to which one or a plurality of processes are allocated using a first control cycle; and a second arithmetic unit for doing cyclic execution of a second task to which one or a plurality of processes are allocated using a second control cycle that is longer than the first control cycle. For the first task, a first data collection process with a first input data as the target and a corresponding first data processing process are allocated. Depending on the setting via the support device, a second data collection process with a second input data as the target and a corresponding second data processing process are allocated to either of the first task and the second task.

Abstract: A control system controls a control target, and includes plural processing resources available for execution of arithmetic processing. The processing modules include a collection module and an anomaly detection module. The collection module collects one or more state values corresponding to a detection target included in the control target. The anomaly detection module calculates a value indicating a possibility that an anomaly has occurred in the detection target based on a feature value calculated from the one more state values having been collected. Each of the collection module and the anomaly detection module is capable of being arranged in a processing resource among the plural processing resources.

Abstract: A control system controls access to data in a device group of devices that communicate with one another. The control system includes a first device of the devices and that receives, in a removable manner, a storage medium in which data is storable, and one or more second devices of the devices. Each member of the devices and the storage medium includes a storage region that retains a list including relevant information associated with each of the members, and a verifier that verifies the relevant information of each of other members included in the list retained in the storage region against the relevant information of each of the other members obtained from each of the other members. The first device accesses the data stored in the storage medium when a result of verification obtained by the verifier of each of the other members but the first device satisfies a condition.

Abstract: A control device includes a controller that executes a control arithmetic calculation controlling a control target; a communication device that executes processing for secure communication using a certificate; a detector that detects that an end of the certificate approaches; and a notification device that notifies that the end of the certificate approaches.
