PURPOSE: To make it possible to perform readily and certainly set up work in an FA system by displaying a set up attitude on a set up display terminal using the set up information having been put into an NC program prior to machining.

CONSTITUTION: A computer 13 transfers job execution data and the cell data of a new address to a cell control unit 14 complying with the requirement in every job completion of machining cells 11-1 and 2, and so on to direct a program file unit 15 to send an NC program to a corresponding machining cell. The program file unit 15 sends the parameter indicating pattern numbers and the distance between jigs to a set up terminal 19 through a LAN 17 and the cell control unit 14 and sends NC data to the corresponding machining cell. The terminal 19 reads the set up attitude data in correspondence with pattern numbers from a memory section, draws the shape of a jig on a CRT, and displays a pallet number and clamp jig number.
