Automation system unified data access for disparate data sources
Historical and real-time data access is leveraged to provide unified data access for interacting with manufacturing process entities such as, for example, process overview displays, charting systems, reporting systems, logging systems, and/or recipe systems and the like. The unified data, for example, allows for playback of historical process overviews for a user selected period of time. In one instance, a “VCR like” user interface can be employed to allow ‘rewinding’ and ‘replaying’ of a historical process overview. This facilitates in proper monitoring and/or troubleshooting of manufacturing processes. The unified availability of past and current data also enables reporting systems to provide “living” reports that automatically update with real-time data. This can allow for efficient comparison of current data with historical data for a given manufacturing process.
1. A system that facilitates monitoring and/or control of a manufacturing process, comprising:
a data retrieval component employed in a human machine interface (HMI) that retrieves historical data and real-time data associated with a manufacturing process in an industrial automation environment from disparate data sources, the data retrieval component retrieves the historical data from a database or a data file by employing a first protocol, the data retrieval component retrieves the real-time process data from the manufacturing process in real-time employing a second protocol;
a unified data access component that abstracts differences between the retrieved historical data and the retrieved real-time data to provide unified process data; and
a process overview display that utilizes the unified process data to provide the real-time data and historical data at the HMI in the same format, and playback of historical process overviews at the HMI, wherein the playback includes playback over a user selected time period.
