<p>PURPOSE:To surely execute transmission/reception to/from a host computer and to collect, store and manage the contents of work at the time of manufactur ing products by recognizing only data having transmitting serial numbers more than the finally transmitting serial number out of data stored in a receiving data storing means as control data. CONSTITUTION:The host computer HST allocates transmitting serial numbers to data relating to an assembled object passing respective processes in a production line and transmits the number-added data. Two communication terminals CT1, CT2 or more receive the data from the HST and write the data in file servers (receiving data storing means) F1 to F3. A working terminal WT controls the sampling of manufacturing history of the assembled object corresponding to data inputted to the production line based upon the written data. The working terminal WT recognizes only the transmitting serial number of the data and data having a transmitting serial number more than the transmitting serial number of the previously received data as control data. Consequently the manufacturing history data of products can be stored.</p> |
