Abstract: Coordinating scheduled events and aperiodic events to execute objects to extract, transform, and load data from source systems to a structured data store. An event manager process executing on a server runtime utilizes event suspension, consolidation, and sequencing techniques to ensure that only one event process is executed for a particular time range.

Abstract: Consolidating events to execute objects to extract, transform, and load data from source systems to a structured data store. An event manager process executing on a server runtime utilizes one or more event properties to determine which events can be consolidated to reduce unnecessary processor utilization.

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.

In addition, the protected configuration data file is made available by obtaining the file from the cloud-based service.

Abstract: Disclosed are systems, servers and methods for improving temperature profile control in a reactor with at least three fixed beds, exothermic reactions and interstage cooling. A model of the temperature differential across the first bed is developed and its error is used to infer unmeasured feed composition disturbances, which are used in the control of the downstream fixed beds for faster response to unmeasured feed composition changes and improved control of the temperature profile throughout the reactor. The first bed model error is then used as an input into an overall model that predicts reactor temperature profiles, which provides advanced notice of reactions in downstream beds, and enables efficient adjustment and compensation to a feed composition change. A Model Predictive Control (MPC) algorithm is applied to adjust the bed intercooling and first bed feed temperature so that the reactor temperature profile can be more precisely controlled.

Abstract: The disclosure is directed to systems and methods for local rendering of 3D models which are then accessed by remote computers. The advantage of the system is that extensive hardware needed for rendering complex 3D models is centralized and can be accessed by smaller remote computers without and special hardware or software installation. The system also provides enhanced security as model data can be restricted to a limited number of servers instead of stored on individual computers.

Abstract: A server system can operate to function as an automatic association of tags defining a system within a process. The operations include accessing tags and associated signals including a plurality of data values over time indicative of a physical property, behavior or measurement of a component of the process. For each signal, calculating a time-weighted average over a specific time period, selecting a specific number of different day periods sampled from the tags and signals, and for each tag, calculating a slope and intercept by calculating a linear regression of plurality of signals over the specific time period. Further, calculating a residual value of each data value of the signals over the specific time period, and calculating a normalized value of each residual value, and then calculating the absolute value of the dot product of the normalized residual value and the residual value of a subsequent number of tags.

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: 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.

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.
