An interface or display routine is provided for use in viewing and configuring a function block that performs integrated optimization and control within a process control system. The interface routine may enable a user to view or configure variables, values or other parameters associated with the integrated optimization and control block within the process control system. For example, the interface routine may display the current operating state of the integrated function block, may enable a user to select inputs and output of the function block for use in providing integrated optimization and control, may enable a user to select a particular or desired optimization function for use in the function block, etc. The interface routine may also display the multiple input output curves associated with the optimizer and the controller sections of the integrated function block in a manner that provides ease of view and selection of these curves as part of the algorithm used by the integrated function block.

Configuration and viewing display for an integrated model predictive control and optimizer function block

A process control configuration system is provided for use in creating or viewing an integrated optimization and control block that implements an optimization routine and a multiple-input/multiple-output control routine. The configuration system may enable a user to display or configure the optimizer or the control routine. A storage routine may store information pertaining to a plurality of control and auxiliary variables and to a plurality of manipulated variables to be used by the optimization routine and/or the control routine. A display routine may present a display to a user regarding the information pertaining to the plurality of control and auxiliary variables and to the plurality of manipulated variables.

Integrated model predictive control and optimization within a process control system

A process control system includes a diagnostic monitoring and display functionality for viewing, in a coherent manner, diagnostic information relating to a process that operates over multiple devices and system components. Although the multiple devices and system components typically encompass widely different device types and operational standards, the process control system incorporates diagnostic information relating to all devices and presents this information to a system user in a uniform manner so that an operating control strategy and the diagnostic information are presented as though all control actions and diagnostic information were performed or generated at a single location. A user-defined diagnostic program is assembled as a set of function blocks and control modules and represented as a set of layers of interconnected control objects identified as modules which include informational structures accessed as attributes. Information is accessed using device hierarchy attribute addressing, supporting direct addressing of I/O signals from modules, bypassing the use of I/O function blocks and avoiding I/O function block behavior.
