1. A computer-implemented control method of factory automation system having a cell formed by a plurality of working machines including at least one automated machine to execute a series of works in accordance with a control program, said method comprising the steps of:

  • extracting, using a computer, information regarding a working sequence of said plurality of working machines and information regarding control of inputs and outputs of said plurality of working machines from a cell control program, which includes specifications of working of said cell as a whole, said cell control program being input to the computer, said cell control program further including information regarding a working sequence of said plurality of working machines, information regarding control of inputs and outputs of said plurality of working machines, information regarding operation control of said automated machine, and information regarding synchronization of operations of said working machines;

    generating, on the basis of said extracted information by using the computer, a sequence control program in which control of the working sequence of said plurality of working machines and control of inputs and outputs of said plurality of working machines are described;

    extracting, from said cell control program by using the computer, information regarding operation control of said automated machine and information regarding synchronization of operations of said working machines;

    generating, on the basis of the information extracted in said extracting step using the computer, an automated machine control program in which processing for control over positioning and operation trajectory of said automated machine are described; and

    controlling working of said cell in accordance with said sequence control program and said automated machine control program.
