Definitions

  • the invention pertains to control systems and, more particularly, to methods and apparatus for distributing, installing and/or validating components of such systems.
  • control and “control systems” refer to the control of a device or system by monitoring one or more of its characteristics. This is used to insure that output, processing, quality and/or efficiency remain within desired parameters over the course of time.
  • digital data processing or other automated apparatus monitor the device or system in question and automatically adjust its operational parameters.
  • such apparatus monitor the device or system and display alarms or other indicia of its characteristics, leaving responsibility for adjustment to the operator.
  • Control is used in a number of fields.
  • Process control for example, is typically employed in the manufacturing sector for process, repetitive and discrete manufactures, though, it also has wide application in electric and other service industries.
  • Environmental control finds application in residential, commercial, institutional and industrial settings, where temperature and other environmental factors must be properly maintained.
  • Control is also used in articles of manufacture, from toasters to aircraft, to monitor and control device operation.
  • one of the CPs is placed in active mode, while its partner is being upgraded.
  • the upgraded unit is then brought on-line, but only in shadow mode. Its operation is monitored by the engineer or operator, e.g., who compares its output with that of the active CP. If satisfied with the upgraded unit, the engineer can make it active, so that the remaining original CP can be upgraded. Redundant, fault-tolerant operation resumes once both CPs are similarly upgraded.
  • An object of this invention is to provide methods and apparatus that overcome these shortcomings. More particularly, an object is to provide improved methods and apparatus that facilitate the distribution, installation and validation of control systems and components.
  • a further object of the invention is to provide such methods and apparatus as facilitate the installation of components into active or on-line control systems.
  • a still further object of the invention is to provide such methods and apparatus as facilitate the distribution of control system components, e.g., from a manufacturer's site, and their installation, e.g., at a remote site.
  • Yet a still further object of the invention is to provide such methods and apparatus as can be readily implemented on existing digital data processing apparatus or special purpose control apparatus.
  • Still yet further related objects of the invention are to provide such methods and apparatus as can be applied in process control systems, environmental control systems, and the like.
  • control system with blocks or other components that facilitate validation of their own replacements.
  • Further aspects of the invention provide control systems in which the components to be validated are downloaded and installed from a remote site, e.g., via e-commerce transaction.
  • the invention provides a control system that includes first and second control components, e.g., flow control objects for a process control system.
  • the first component is coupled to a third control component, with which it transfers information, e.g., as part of an active or ongoing control process.
  • the third component can be, for example, a temperature control object with which the first component (e.g., a flow control object) is in a cascaded arrangement.
  • the second component can be, for example, an update or other potential replacement for the first component.
  • the second component can be a similar control object with new or improved functionality.
  • the first and/or second components of a control system can effect substitution of the second component for the first. More particularly, they can effect coupling of the second component for information transfer with the third component and decoupling of the first component from such transfer with the third component. Preferably, such coupling and decoupling occur while the control system remains active.
  • the second component prior to its substitution for the first component, is coupled to receive information from the third component and/or any sources from which the first component receives information.
  • the second component is at least temporarily prevented from outputting information to any sinks to which the first component sends information.
  • the output of the second component can be routed, along with that of the first component, to one or more comparators. These can reside elsewhere in the control system, e.g., in a supervisor object, or within the first and/or second components themselves. Substitution of the second component for the first rests on the success of comparison of their outputs and, in most applications, on confirmation by the operator or test engineer.
  • a comparator can check the output of a newly installed flow control object against the output of an old object it is intended to replace.
  • the comparator can notify the operator of the results of the comparison and, if the operator approves, the new object can be substituted for the old.
  • a list maintained in the first component can identify its various parameters that are sinks for the third component and, likewise, parameters in the third (or other components) for which it (the first component) is the source.
  • Substitution of the second component for the first may be effected, for example, by replacing all connections to/from the first component with connections to/from the second component.
  • Still further aspects of the invention provide a control system as described above in which the first and second components are resident on a control processor, a "smart" field device, or on another digital data processor-based control device.
  • the configured second component can be downloaded to that device, e.g., from a control system work station, while the control system is active and while the first component is operational, e.g., exchanging information with the third component.
  • downloading from a manufacturer's site to the workstation can be effected as part of a contracted-for maintenance transaction, an upgrade transaction and or as part of an e-commerce transaction, e.g., between the customer and the manufacturer.
  • Such downloading moreover, can be instigated by the customer or, automatically, by the first component or a software agent within the control system.
  • Yet still further aspects of the invention provide methods for control and methods for distributing and/or installing control components paralleling the operations described above.

Without detracting from breadth of the teachings herein, site 16 is referred to hereinafter as a "site server.”
  • Process 12 represents any industrial, manufacturing, service, environmental or other process amenable to monitoring or control (hereinafter, collectively, "control"). This is illustrated in greater detail in Figure 2. wherein a simple such process is shown as including valve 18 that governs the rate of fluid flow to aeration tank 20 which, in turn, transfers the liquid to storage tank 22. Sensors 24 and 26 monitor the state of process 12 and, thereby, facilitate its control by process control system 28 operating on the one or more digital data processors represented by element 10. Thus, sensor 24 is disposed in or adjacent to tank 20 for measuring the temperature of fluid therein, while sensor 26 measures the flow of fluid from aeration tank 20 to storage tank 22.

Abstract

Un système de commande comporte des blocs (30) ou autres constituants facilitant la validation de leurs propres remplacements, par exemple, téléchargés par des transactions de commerce électronique (11). Le système comprend un premier constituant (30) de commande de processus et un second constituant (30a) de commande de processus. Le premier constituant est couplé à un troisième constituant (32) de commande de processus, avec lequel il transfère des informations, par exemple, en tant que partie d'un processus de commande actif ou en cours. Le second constituant (30a) peut être, par exemple, un élément de remplacement actualisé ou potentiel du premier constituant. Les premier et/ou second constituants peuvent procéder à des substitutions du second constituant au premier. Plus particulièrement, ils peuvent procéder au couplage du second constituant à des fins de transfert d'informations avec le troisième constituant et au découplage du premier constituant à partir de ce transfert avec le troisième constituant. De préférence, ce couplage et ce découplage se produisent pendant que le système de commande processus est actif.
