Abstract: An intelligent interface system is provided for connecting an external application to a distributed control system (DCS). The interface system is operable to automatically scan the DCS to determine its configuration and build a topology model of the DCS. The topology model is used to determine whether data requested from a module in the DCS can be provided by the module. The topology model is constructed to be thread-safe. A throttling mechanism in the interface system protects the DCS from being subjected to excessive data requests.
