Abstract: A program includes a parameter numeric value and a parameter code and a parameter name that are associated with the parameter numeric value. A dialog box information creation processing unit recognizes the parameter code and the parameter name, which are included in the program, as a parameter item, and creates dialog box information from the recognized parameter code and parameter name and the associated parameter numeric value. The parameter numeric value within the created dialog box information is editable on a dialog box display screen. When the parameter numeric value is updated, a process of changing the corresponding parameter numeric value in the program to the updated parameter numeric value is executed.

Abstract: In a flexible manufacturing system, a control apparatus for a transfer device stores in a memory section thereof correlation information for correlating workpieces (ante-machining workpieces) to be attached to pallets with blank materials contained in blank material baskets. When a selected one of the pallets is to be transferred to a pallet loading station, the control apparatus determines blank materials corresponding to the workpieces to be attached to the selected one of the pallets based on the correlation information and then, controls the transfer device to transfer a blank material basket containing the determined blank materials from a basket rack to a basket loading station located adjacent to the pallet loading station in connection with transferring the selected one of the pallets to the pallet loading station. Thus, when the selected one of the pallets is transferred to the pallet loading station, it becomes possible to reduce the time taken for the worker to search for the blank material basket.
