PURPOSE:To reduce the load of a host system by transferring a lot control table containing a process procedure to a controller of a 1st process from a controller which integrates shops via an LAN at application of a lot and proceeding to the next process when the preceding process is through. CONSTITUTION:When a lot A of products X is applied, a progress control system host 12 produces a lot control table 16 where the manufacturing procedure of the product X is written. The table 16 is delivered to a controller 13 of a 1st process (a) of the product X via an LAN 11. The controller 13 writes the work data of the process (a) into the table 16 when the work of the lot A is finished and transfers the table 16 to a controller 14 of the next process (b) via the LAN 11 as a lot control table 17. |
