Abstract
A distributed database system within an industrial automation environment comprises a plurality of associated programmable logic controllers, wherein each of the programmable logic controllers includes data relating to one of a process and a device. Furthermore, the data within the plurality of programmable logic controllers can conform to a hierarchically structured data model, which, for example, can be based upon ISA S95, ISA S88, OMAC, or any suitable combination thereof. A reception component receives and services a request for data that is located within at least one of the programmable logic controllers.
