  • Patent number: 10317855
    Abstract: A system, method, and an apparatus relating to data collection regarding valve movement over a period of time in order to determine the effects of stiction on the valve. With data collection done over a period of time, it is possible to remove dependency on a high speed method of data collection. The evaluation of the valve movement includes consideration of a manipulated variable (MV) for diagnosis, or detection, of stiction of the valve.

  • Publication number: 20160132037
    Abstract: The invention comprises a configuration system for a process control system that is configured for performing process control. The configuration system comprises a repository including at least one memory and one or more definition modules stored in the memory. Each definition module may comprise control logic for controlling an associated component. The configuration system also comprises a repository controller. The repository controller may be configured to receive user input identifying one or more properties of a specific component within the industrial system. The repository controller may additionally enable selection of a definition module from within the repository, wherein the selected definition module comprises control logic for controlling an associated component having the identified one more component properties. The invention additionally provides a method for configuring a process control system for performing process control.
