A control system for controlling a production facility having a plurality of automatic working apparatuses, installed in a plurality of work stations arranged in succession, respectively, for performing different types of specified operations on work units at said work stations to complete said work units which are assembled to products, said control system comprising:

• first control means, provided for each of said automatic working apparatuses, for controlling each said automatic working apparatus independently from the other automatic working apparatuses to perform a specified operation on each said work unit, each said first control means being organized by at least a first data memory which has a common memory area shared in common by first data memories of the other first control means for the other automatic working apparatuses and an individual memory area exclusive thereto;
• and
• second control means, organized by at least a second data memory area sharing said common memory area, for storing operation data indicating at least types of said specified operations performed by said automatic working apparatuses in said second data memory area, said second control means being configured to govern said first control means for said working apparatuses and to transfer said data of said specified operations to said common memory area of said first data memories from said second data memory all together, whereby said first control means control said automatic working apparatuses to perform said different types of specified operations on a work unit, respectively, according to said data of said specified operations and to complete said work unit.
