Abstract:
PURPOSE:To set data in a state where the pictures opened to users are transformed into a ROM for protection by dividing the data on the display of those pictures into the picture constitution data and the set data and transforming the picture constitution data into a ROM like a working program, a sequence program, etc. CONSTITUTION:The parameter for production of pictures is invalidated after production of a picture and therefore data can be supplied into the parenthesis of the picture when the next picture is called. Even in such a case, it is allowed to write data into the parenthesis only when a writing mode is turned on by a set data writing protection means 31 to avoid such a case where data are inadvertently rewritten. In other words, the picture data produced in a valid mode of production of screens is stored in a picture constitution data memory 32 and can be transformed into a ROM. While the set data supplied in an invalid mode of picture production and in a writing ON state is stored in a set data memory 33 and can be rewritten as necessary in a RAM state.
