Abstract
The present invention is characterized by the following: Definition files, which define the way diagnostic parameters and other information retained by field devices are displayed, are created. The parameters of field devices are displayed according to these definition files. By implementing these processes, a data display unit for use with field devices is realized, thereby making it possible to easily obtain parameters necessary to know the status of a field device without the need for in-depth knowledge about the parameters. It is also possible to identify parameters without having to go out to the site where the field device is installed.
