Abstract: Methods and apparatus to provide a role-based user interface are disclosed herein. An example system disclosed includes a display device to depict a user interface. The example system also includes a processor. The example processor is to receive object information for an object in a process control system during a session, determine a user role based on the session, determine whether the object information is qualifying information based on the user role, and display the object information via the user interface when the object information is qualifying information.

Abstract: Example methods and apparatus to manage process control search results are disclosed. A disclosed example method includes receiving a search parameter from a user via an application to view search results associated with the search parameter, determining a display context based on the application, searching a search index for control parameters that match the search parameter to form a set of matched control parameters, wherein the search index includes control parameters that correspond to runtime data generated by a controller within a process control system, and rendering the set of matched control parameters for display via the application as the search results based on the determined display context.

Abstract: A method for adjusting startup floor pressure levels of HRSG steam circuits is implemented by a pressure controlling computing device including a processor and a memory. The method includes receiving a plurality of measured plant operating values associated with a HRSG steam circuit, identifying a plurality of candidate pressure levels for use in pressurizing the HRSG steam circuit, determining a calculated steam velocity level for each of the plurality of candidate pressure levels, identifying a steam velocity limit for a steam piping section of the HRSG steam circuit, selecting a lowest pressure level of the plurality of candidate pressure levels, wherein the lowest pressure level is associated with a determined calculated steam velocity level that does not exceed the identified velocity limit, and pressurizing the HRSG steam circuit to the selected lowest pressure level.

Abstract: Techniques for flexibly configuring an operating process plant or process control system enable a change to a parent object to be selectively propagated to child objects derived from the parent object, so that a first subset of child objects and their respective instantiations are updated with the change, while a second subset and their respective instantiations remain unchanged. The parent object may be a class or instance process object corresponding to a process entity, and the first and/or the second subset of child objects may be selected. In some cases, the change may have been a propagated change, to the parent object, from a child object that is excluded from the first or the second subset of child objects. In some cases, the change may first be propagated to an instance object derived from the parent object, and then propagated from the instance object to a child object.

Abstract: Example methods and apparatus to present recipe progress status information are disclosed. A disclosed example method involves displaying a user interface screen associated with a recipe being executed in a process control system. The recipe includes a plurality of process phases. A plurality of process stage progress indicator are displayed in the user interface screen in an arrangement representative of the process flow of the recipe. Each of the process stage progress indicators is representative of at least one of the process phases of the recipe. A first one of the process stage progress indicators is indicative of a progress of at least one of the process phases. The first process stage progress indicator is updated in substantially real-time based on information received from the process control system.
