PURPOSE: To realize the automatic production of a control program which is converted into an internal unit by writing the external signal value unit and the internal unit into an input/output defition table by storing previously the relation between the unit of the input/output signal and the internal unit of computer control logic.
CONSTITUTION: An input/output definition table production means (a) produces an input/output definition table containing an entry column for the relation between the unit of the input/output signal and the internal unit of the control logic. A conversion formula memory means (b) stores a conversion formula between the unit of the input/output signal and the control logic internal unit. An entry column writing means (d) writes both units into the corresponding entry column of the input/output definition table displayed by an input/output definition table display means (c) and completes an input/output definition table. An automatic control program production means (e) produces automatically a control program based on the entry column data of the completed input/output definition table and the stored conversion formula.
