A programmable logic controller collects data held by a device as a collection target out of the plurality of devices in accordance with a predetermined collection setting for each scan cycle of the user program, classifies each of the devices into one of a plurality of types on the basis of a characteristic of the collected time-series data of each of the devices, and determines a detection algorithm used in identification of the device as an abnormal device in accordance with the time-series data of the device collected by the collection section and the type of the device classified by the classification section for each of the devices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Programmable logic controller and analyzer","description":"An object of the present invention is to efficiently identify an abnormal device by analyzing and classifying characteristics such as periodicity and continuity of data related to each device.
