Embodiment Construction

[0035] refer to figure 1 A process control system 10 includes a process controller 11 communicatively connected to a historian 12 and one or more host workstations or computers 13 (which may be any type of personal computer, workstation, etc.), each having a display screen 14. Controller 11 is also connected to field devices 15-22 through input, output (I / O) cards 26 and 28. Historian repository 12 can be any desired type of data acquisition device with any desired type of memory and any desired or known software, hardware or firmware for storing data, and historian repository 12 can also be associated with a workstation 13 separate (eg figure 1 shown in ) or as part of the workstation 13. Controller 11, can be, for example, the DeltaV that Fisher-Rosemount System company sells TM The controller is communicatively connected to the host computer 13 and the historian 12 via, for example, an Ethernet connection or any other desired communication network 29 . The communication...

Abstract

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.
