Abstract: A data creating device includes a composite data creating portion that creates a copy of data that is stored in a data storing portion and creates composite data by applying changed data that has been inputted through a data inputting portion, a comparing portion that compares the composite data created by the composite data creating portion and the data that is stored in the data storing portion to extract, from the composite data, parts that are different from the data, and a display controlling portion that displays, on a displaying portion, the data that is stored in the data storing portion along with the composite data, in a form wherein it is possible to identify the parts in the composite data that are different, extracted by the comparing portion, and parts that are same.

Abstract: A data creating device includes an instrument control data generating portion that creates instrument definition data wherein fields for defining a field instrument in an instrument controlling device, including instrument tag information for the field instrument, are added to point definition data. The data creating device also includes a display controlling portion that controls creation and display of display data for inputting the instrument tag information into instrument tag information fields of the instrument definition data. The display data that is created by the display controlling portion is displayed on the displaying portion under control of the display controlling portion.
