<p>A method comprising receiving a request for process data associated with a field device, searching a database for a descriptor file that includes the requested process data, and accessing the descriptor file to retrieve the process data to display within an application, wherein the process data is retrieved using a schema that specifies that the process data is located at an object referenced by a file entry that is part of a section of a file body included within the file. The descriptor file will be created having an open-file-description for each component associated with the field device, sections in each open-file-description that include related portions of process data and file entries in each section.</p> |
