Abstract: Associating comments with tags in a managed historian system in accordance with a flexible, platform-independent data structure. A worker role instance automatically associates received comments with a process tag at a particular time in response to receiving the comments. The worker role instance stores the comments in the flexible, platform-independent data structure such that the comment is provided in association with the tag at the particular time in response to a display or search request for the tag.

Abstract: An event historian system receives event data from a client system via a network connection and stores the event data in a block data storage system. An event data block in which to store the received event data is selected based on the time range of the occurrence of the received event data. The received event data is stored in a snapshot within the event data block. Event property data is extracted from the received event data and used to build a plurality of event property index files.

Abstract: Annotating content, comprising data values of one or more tags corresponding to a process device within a continuous process, with content descriptors in a historian system. Content descriptors enable indexing and saving content within a search service database for later retrieval by search strings that match the content descriptors. Content having one or more common content descriptors are retrieved and transmitted to a client computing device via a communications network for displaying in a dashboard on the client computing device.

Abstract: 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.

Abstract: Some embodiments of the invention provide systems and methods for securing configuration information for cloud-based services. Some embodiments include a system comprising a data store and data sets including plant process information and configuration information. A memory device stores computer-executable instructions executable by a processor coupled to the cloud service.

Abstract: A historian system stores data values and associated metadata. The system has a historian data server, a metadata server, and one or more data collector devices. The data collector devices collect data values from a set of one or more connected hardware devices and send the collected data values to the historian data server. The data collector devices also create tag metadata associated with the collected data values and send the created tag metadata to the metadata server. The historian data server receives the collected data values and stores the collected data values in a memory storage device. The metadata server receives the tag metadata and stores the tag metadata in a memory storage device.

Abstract: A system for historizing process control data. A configurator module registers a data source device with a historian server and indicates to the historian server to generate data source registration information for identifying the registered data source device. The historian server generates and stores the data source registration information. The historian server also generates a connection token comprising the data source registration information. The configurator module forwards the connection token to the data source device, which stores the token and sends it to the historian server with data. The historian server compares the connection token received from the data source device to the connection token stored by the historian server, wherein if they match, the historian server stores the data from data source device.

Abstract: Targeted distributing of reports containing historical process control information to particular user devices via a communications network. A curating service permits assigning a score to each report based on an interest level value of the historical process control information to a user associated with each user device and/or an urgency value of the historical process control information. Routing reports to user devices based on the score raises visibility of the historical process control information without overburdening the communications network.
