Abstract: A differential logger stores, into a log storage from a device memory, a differential log being a log of a device value that has changed at each execution of a control program. A collective logger collectively stores, at a set time, collection target device values into the log storage as reference data to be used to collect the differential log. A split logger acquires as split logs, after the set time, logs of the device values multiple times, and stores the split logs into the reference data storage. The differential logger overwrites data in the log storage with the differential log after new reference data is stored into the log storage.
