Claim Text:
1. A data collection and transfer apparatus comprising: a temporary memory; a buffer memory that has a larger capacity than a capacity of the temporary memory and has a lower data storage speed than a data storage speed of the temporary memory; a data collector to collect control data from a manufacturing apparatus and store the control data in the temporary memory; a data transferor to transfer the control data stored in the temporary memory to an upper-level server; a network monitor to monitor a network connecting the upper-level server and the data transferor and to detect whether a fault occurs in the network; and a setter that includes a collection-data-setting storage, a collection-period-setting storage, a transfer-period-setting storage, a buffering-data-setting storage, and a buffering-period-setting storage, wherein in response to the network monitor not detecting the fault, the data collector collects the control data specified in the collection-data-setting storage with a first period specified in the collection-period-setting storage and stores the control data in the temporary memory, and the data transferor transfers the control data stored in the temporary memory to the upper-level server with a second period specified in the transfer-period-setting storage, in response the network monitor detecting the fault, the data collector collects the control data specified in the buffering-data-setting storage with a third period specified in the buffering-period-setting storage and stores the control data in the temporary memory, and the control data stored in the temporary memory is stored in the buffer memory with a fourth period specified in the buffering-period-setting storage, and the fourth period specified in the buffering-period-setting storage is automatically determined based on a maximum data storage speed of the buffer memory.
