Abstract: A historian system enables the creation, storage, and retrieval of extended metadata properties. A tag metadata database module of the historian system stores tag metadata received over a network connection in a tag metadata database and retrieves tag metadata in response to requests received over the network and from within the historian system. An extended property database module creates extended properties associated with a tag metadata instance in response to requests, stores the created extended properties, and retrieves the stored extended properties in response to requests. The extended property search index module indexes extended properties as they are created, searches the indexed extended properties in response to requests, and provides the indexes of extended properties to enable location of the extended properties in the extended property database.

Abstract: A system for developing a simulation of a process. In one aspect, a system creates a first model within the simulation. The first model represents a part of the process and comprises a first port to which other models may be connected. The system also creates a second model within the simulation. The second model represents another part of the process and comprises a second port to which other models may be connected. The system then connects the first port and the second port together. Upon connection, the system allocates a memory location as a connection variable that represents a type of information transfer between the first and second ports. A first port variable, which represents a value transferrable through the first port, is set to reference the value at the allocated memory location. Similarly, a second port variable, which represents a value transferrable through the second port, is also set to reference the value at the allocated memory location.

Abstract: A processor executable method, system, and computer-readable media expedite the process of entering equations for use in developing simulations of chemical processes. The process of entering equations is expedited by dynamically inferring the dimensions of variables. The process infers the dimensions of all variables in user-added equations, and infers the dimensions of each variable in a user-added equation sequentially. The process automatically creates variables with unassigned dimensions in response to indications, such as inputs from a user, to declare new equations. The process assigns dimensions to variables based on relations between variables, such as logical relations between the dimensions of variables.

Abstract: Automated correlation of process attribute value changes with events related to the changes. A managed historian utilizes a namespace property to correlate process tag values with corresponding events. The managed historian generates and provides to remote user devices a graphical user interface that includes a plot of data values of the process tag and a visual icon representing the event overlaid atop the plot of data values.

Further, the system and method includes configuring the edge computing device as a human-machine-interface, coupling a data ingester and establishing a data connection to the distributed environment of the network, operating the data ingester to discover the device and receive data from the device, and processing a local graphical visualization of at least one update to the network.

Abstract: Configuration utilities, such as object wizards, enable automatic configuration of domain-specific assets from object templates based on domain specific options. In an aspect, an application object template library stores a set of previously defined application object templates. The templates each include a superset of options common to a set of related domain objects. A configuration utility is configured for specifying at least one domain-specific option of the superset and creating an application object instance to be included in an application. The application object instance comprising at least one of the application object templates having the specified domain-specific option.

Abstract: Automated recovery of execution roles in a distributed historian system in accordance with actions and rules customized to each execution role. A monitoring service monitors the health status of execution roles and automatically performs a corrective action in response to the health state of an execution role triggering a predetermined rule.

Abstract: A recipe management system includes a versioning system that tracks the revision history of templates and their child instances. Modifications to templates and instances create new records with new primary key identifiers and version identifiers. However, each new version of a template or instance has the same root identifier as the prior versions. When a template is modified, a flag is set in its child instances, but they are not modified automatically. When an instance is modified, it has no effect on the parent template. At runtime, a recipe model is loaded to an equipment model to execute a recipe on a piece of equipment. Only approved versions of equipment models are used during execution, even if newer versions exist. During execution, new equipment models can be created. The recipe management system includes an execution engine that can be hosted as a standalone executable or in a system platform.

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: 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: A method and system provides for asynchronous two-way binding between a user interface and a data model which are implemented on different frameworks. The system includes data, data model, and bridge controllers. The data controller provides a front-end binding framework that interacts with a user interface of a user device to manage a bindable property or method for a view on the user device. The data model controller provides a back-end binding framework that manages a data model, the front-end binding framework and the back-end binding framework being different types of frameworks. The bridge controller implements asynchronous two-way binding for the bindable property or method between the front-end binding framework and the back-end binding framework to update the bindable property or method in the data model when data changes at the user interface and to update the view on the user device when data changes at the data model.
