PROBLEM TO BE SOLVED: To enable switching between simple display and detailed display of data stored in a ladder component such as a shift register etc. while enabling automatic registration of data of the ladder component. SOLUTION: This method includes: when a monitor range of data storage areas in the ladder component is not specified, simply displaying data stored in a data storage area corresponding to the start and end addresses of the ladder component, and when the monitor range of data storage areas in the ladder component is specified, displaying the data stored in the specified data storage area in detail. Further, an input condition description display area can be horizontally scrolled. Even a ladder component in a row portion which is not displayed in the input condition description display area due to the horizontal scroll and can not be recognized by a user, can be automatically registered in a data view dialogue.
