A method and system for exchanging at least one data value between a first device and at least one second device, including providing at least one data structure at the first device, the data structure including at least one descriptive field and an associated at least one data value field, the at least one data value field including the least one data value, the at least one descriptive field including a usage type field having usage type data to associate the at least one data value field with a data type, transmitting the at least one data structure from the first device to the at least one second device, and, based on at least the usage type data, at the at least one second device, extracting the at least one data value from the at least one data value field.

Method and data structure for exchanging data

Systems and methods for storing configuration data for process control systems are described. In one embodiment, a method for storing configuration data for a Fieldbus device can include generating one or more first documents based on a first document type definition in a markup language, and generating one or more second documents based on a second document type definition in the markup language. The one or more first documents can include one or more block identifiers for identifying one or more function blocks associated with the Fieldbus device. The one or more second documents can be associated with the one or more function blocks and can include one or more parameter identifiers for identifying one or more parameters associated with the one or more function blocks.
