An address of an input and output equipment 4 as to a ladder symbol, and a data including a variable name (for example SW 1) corresponding thereto are registered in a single data file 33, for example, when the program is prepared. When the ladder symbol on a ladder window is dragged and dropped to the image preparing window in a following image preparation, and the editor 32b refers to the variable name copied onto a memory part 34 by a copying function part 32c to display a mark (component) corresponding thereto on the image preparing window and to display the variable name as the supplementary information on the mark.</p> |
