Abstract: A device management system comprises a data collection server and edge server including an adapter that transfers a device-related data set of an industrial device. Upon receipt of the device-related data set and when the data collection server is unable to specify a row that both adapter identification information of the device-related data set and device identification information match, in a devices list table and when the data collection server is able to specify a location name of a row that only the adapter identification information matches, in the devices list table, the data collection server is configured to generate/assign a new unique device identification ID based on the specified location name, the locations list table, and the devices list table. The data collection server associates the new unique device identification ID with the received device-related data set, and then stores the device-related data set in the data accumulation section.
