Data provided by external sources is visualized. A user interface for a data visualization platform receives a query from a client, and forwards it to an application programming interface for an internal data source provider. The application programming interface ('API') forwards the query to a retrieval service, which identifies an external data source provider specified by a tag in the query and forwards the query to the external data source provider. The retrieval service retrieves a content stream from the external data source provider in response to the query being enhanced by a retrieval mode supported by the external data source provider or the retrieval service. The retrieval service processes the content stream, including identifying a format of the content stream, and forwards the processed content stream to the API, which forwards the processed content stream to the user interface, which visualizes the processed content stream on the client.

Visualizing data provided by external sources

Operational historian system retrieving summary data values and source data values based on alignment between a summarization cycle duration and a query cycle duration. A retrieval service process executing on a historian device utilizes a summarization cycle duration, including start and/or end times thereof, and a query cycle duration, including start and/or end times thereof, to determine whether to retrieve, via a communications network, source tag data and/or summary tag data from memory storage devices.

Summarization retrieval in a process control environment

Some embodiments include a system and method of providing a historian that receives operational state data from a device of an industrial process of a network, where the operational state data is stored as time-series data, and processing at least one data query from at least one user coupled to the network. Based at least in part on the at least one data query and at least one dynamic cycle, at least some of the time-series data is retrieved, where the dynamic cycle is based on at least one tag associated with the time-series data. Further, based at least in part on at least some of the time-series data, at least one graphical representation of one or more tags is displayed, where each tag of the one or more tags represents an attribute of at least one process associated with the at least one device.

Dynamic summarization of process data system and method

Processing raw data stored in an historian device for determining an amount of products passed through a process element in a process control environment is described. A count value is incremented by a counter at a rate at which products pass through the process element. The count value rolls over to zero when the count value reaches a rollover value R. An historian device periodically receives count value data points from the counter. A deadband value D is set in the historian device for distinguishing between rollovers, resets, and reversals. A client device queries the historian device for an amount of products passed through the process element for a timeframe. The historian device selects a set of count value data points from within the queried timeframe. The historian device determines, based on the selected data points and their quality, an amount of products passed through the process element.
