Abstract

An arrangement, storage medium, and method are provided for accessing monitoring data from a storage arrangement of a processing system using a Web Service, in which the monitoring data is associated with a field device. For example, the monitoring data may be in an Extensible Markup Language (“XML”) format, and a Simple Object Access Protocol can be used to access a particular portion of the monitoring data from the database. Moreover, based on the monitoring data, the field device can be replaced before problems arise therewith.
