Abstract
Methods and systems for integrating external and/or enterprise data into a process control system are disclosed. A user interface may be provided to enable browsing and selection of a data item from an external and/or enterprise data source. The selected data item may be associated with a process control entity. At run time, independent of a configuration of the process control entity, an external data integration server or instance of an external data integration service at a process control computing device may periodically communicate with the data source to obtain an updated current value and updated current status for the selected data item for use by the process control entity. The external data integration server and/or external data integration service may consolidate access of external/enterprise data across process control entities, optimize communications with various data sources, and maintain a status of communication with each various data source.
