Abstract: A data collection and transfer apparatus includes: a memory; a buffer having large capacity and low data storage speed; a collecting unit collecting data and storing it in the memory; a transferring unit transferring data stored in the memory to a server; a monitoring unit monitoring a network; and a setting unit retaining storages. When fault is not detected, the collecting unit collects data specified in collection-data-setting storage with period specified in collection-period-setting storage and stores it in the memory and the transferring unit transfers data stored in the memory to the server with period specified in transfer-period-setting storage, and when fault is detected, the collecting unit collects data specified in buffer-data-setting storage with period specified in buffer-period-setting storage and stores it in the memory and data stored in the memory is stored in the buffer with period specified in the buffer-period-setting storage.

Abstract: A logging device of the present invention includes a collection unit for correlating a production data obtained from a production apparatus with an identification data specific to a product produced by the production apparatus and for collecting these data; and an output unit for outputting the identification data collected by the collection unit to a traceability file and for outputting the production data collected by the collection unit into an area in the traceability file, corresponding to the identification data correlated with the production data. According to the present invention, processing loads to the logging device can be reduced in creating a traceability file, and a traceability file can be created without requiring a particular memory area for storing data collected by the logging device.
