Abstract:
A data collection and viewing application provides a user interface that allows a user to quickly and easily examine a particular batch process or a batch run, to compare separate batch runs and/or to determine whether the particular batch run deviates from a norm, without having to perform a lot of manual data manipulation. To this end, the user interface provides or creates a compact graphical representation of a batch, illustrating a number of different types of batch-related data in relation to one another in a manner that enables a user to easily view or understand the operation of the batch run, either alone or as compared with one or more other batch runs. Moreover, process alarms, alerts, events, as well as other information may be placed in one or more additional layers, and the various layers may be shown together to provide a compact graphical view of the batch.
Abstract:
Secure data write apparatus and methods for use in safety instrumented process control systems select a parameter associated with a process control element within the process control system and send first data associated with the parameter to the process control element. A confirmation associated with a request to write the first data to the process control element is received from a user and the second data is sent to the process control element in response to receiving the confirmation. The first and second data are compared at the process control element and the first or second data are written to a location in the process control element associated with the parameter if the first and second data are at least substantially identical.
Abstract:
A data collection and viewing application associated with a batch process control system used within a process plant provides a user interface that allows a user to quickly and easily examine a particular batch process or a batch run, to compare separate batch runs and/or to determine whether the particular batch run deviates from a norm, without having to perform a lot of manual data manipulation. To this end, the user interface provides or creates a compact graphical representation of a batch, illustrating a number of different types of batch-related data in relation to one another in a manner that enables a user to easily view or understand the operation of the batch run, either alone or as compared with one or more other batch runs. Generally speaking, the compact batch view includes a number of graphical layers which are juxtaposed or interleaved on a display, with each of the layers providing different types of information about the operation of the batch, time synchronized with one another. A base layer of the compact batch view may describe or indicate the duration of the batch from an activate time to a deactivate time, while different aspects of the procedural elements, steps or stages of the batch process, such as those identified by the S88 standard, may be illustrated in one or more additional layers. Moreover, process alarms, alerts, events, etc. as well as other information may be placed in one or more additional layers, and the various layers may be shown together to provide a compact graphical view of the batch.
Abstract:
Example methods and apparatus to bind properties in a process control system are disclosed. A disclosed example method involves associating a binding type with a property of a configuration element. A plurality of values for the property are then retrieved based on the plurality of values being associated with the binding type. At least some of the plurality of values are presented to a user. The example method also involves receiving a user-selected value from the at least some of the plurality of property values and generating a binding reference to bind the user-selected value to the configuration element.
Abstract:
Timeline presentations of process control system alarms are described. An operator interface apparatus for a process control system is described that includes an operator display module to present an operator application on a display. The operator interface also includes an alarm presentation interface to be presented on the display via the operator application. The alarm presentation interface includes a timeline to graphically indicate a temporal relationship of a plurality of active alarms of the process control system.
Abstract:
Methods and apparatus to automatically link process control graphics to process control algorithm information are described. An example method involves displaying a first process control image including process control algorithm information and displaying adjacent to the first process control image a second process control image to include process control graphics. The method automatically links at least some of the process control algorithm information to a graphic in the second process control image in response to user inputs associated with the first and second process control images.

Abstract:
A graphical editor for creating operator displays and configuring control strategies in a process control plant or system may present a coherent view for the multiple graphical or control strategy items depicted within or associated with the display and strategy. For each graphical item, the view may hierarchically show default and modified values, animation expressions, and event handler scripts. The view may allow a configuration engineer to group, order, and filter various graphical or control strategy items within a single display to present a cohesive view of how the multiple items within the display are capable of being configured for events, animations, and control strategies within the operator display. Providing this cohesive view may allow the user to view and configure graphical items and control strategies without having to open and dismiss dialogs for each configuration task.
Abstract:
A selector shape may serve as the background to a configurable composite shape and may include one or more expressions that are evaluated to select between several composite shape definitions via links to the definition. Each selector shape includes an animation expression and a lookup table converter to select an identifier of the composite definition to be loaded and displayed. When the value of the animation expression changes, the value may be matched to the name of a new composite definition using the lookup table, and the new definition may be displayed. The previously-used composite definition may then be marked for removal by a caching system, and removed. These selector shapes also enable the same graphic element to be used in displays designed for different types of display devices, such as display devices having large display screens, standard computer screens and very small display screens.
