摘要:
A data modeling studio provides a structured environment for graphically creating and executing models which may be configured for diagnosis, prognosis, analysis, identifying relationships, etc., within a process plant. The data modeling studio includes a configuration engine for generating user interface elements to facilitate graphical construction of a model and a runtime engine for executing data models in, for example, an offline or an on-line environment. The configuration engine includes an interface routine that generates user interface elements, a plurality of templates stored in memory that serve as the building blocks of the model and a model compiler that converts the graphical model into a data format executable by the run-time engine. The run time engine executes the model to produce the desired output and may include a retrieval routine for retrieving data corresponding to the templates from memory and a modeling routine for executing the executable model.
摘要:
A process control monitoring system for a process control plant uses graphic trend symbols to assist in detecting and monitoring trends of process variables within the process control plant. A graphic display application within the process control monitoring system may implement and display each graphic trend symbol to graphically indicate or encapsulate current trend and value information of a process variable within the process control plant. The graphic display application may display the graphic trend symbol in a spatially realistic location within a graphical representation of the process control plant while maintaining the hierarchical structure or each hierarchical level of the process plant. The graphic display application may also include a navigation pane and a zoom feature that enable a user to quickly drill down through tend data to obtain more information and to support problem identification and diagnosis tasks.

摘要:
A system for modifying process control data comprising a database configured to store process control data; a database server communicatively coupled to the database and configured to access the process control data in the database; a query builder communicatively coupled to the database server and configured to generate queries and communicate the queries to the database server, to enable the database server to retrieve the process control data from the database based on the queries; and a data interface communicatively coupled to the query builder and configured to import or export the process control data in an extensible markup language format.
