Patent number: 8620618Abstract: A process control system uses an asset optimization reporter to collect status information of dissimilar types pertaining to the assets of a process plant from various data sources of the plant including, for example, data tools, data collectors, and data generators. This status information is used to generate reports that may be displayed to various users, including maintenance persons, process control persons and business persons. The status information may be used as the basis for further types of status information and/or be categorized in based on an assessment of relative consequence, where each category has a spectrum of status quality values between a good status quality and a relatively worse status quality.Type: GrantFiled: November 25, 2009Date of Patent: December 31, 2013Assignee: Fisher-Rosemount Systems, Inc.Inventors: Evren Eryurek, Stuart Harris, Scott Nels Hokeness, Todd Reeves, Raymond E. Garvey, III

Patent number: 8174402Abstract: A machine condition monitor resides in close proximity to a machine train, such as an AC inductive electric motor coupled to a driven unit such as a centrifugal pump or fan. A plurality of sensing devices are connected to the machine and the machine condition monitor. Machine state and condition parameters sensed by these devices are utilized by the machine condition monitor to derive machine condition values for each component and for the machine train as a whole. These derived condition values are transmitted via an industrial communications network to a control center where they can be trended and monitored. With no particular knowledge of machine analysis techniques or severity of specific machine faults, and no special training, Operators and Production Planners can use the condition values to plan production schedules, adjust process parameters, and request appropriate maintenance action.Type: GrantFiled: January 11, 2008Date of Patent: May 8, 2012Assignee: CSI Technology, Inc.Inventors: Kai Bouse, Stewart V. Bowers, III, Jim Robinson, Richard Piety, Todd Reeves

Patent number: 7142990Abstract: Sensors detect machine parameters such as vibration, turning speed, and temperature, and a local processor performs logic operations based on the parameters and inference rules to produce fault information that is reported to a system processor, which selectively uses the fault information to control the plant machines. The inference rules include rules for determining faults as to balance, alignment, bearing condition, electrical condition, and cavitation. The inference rules are contained in rules code that is separate from the analysis code that performs the logical operations. Thus, the inference rules may be easily changed without changing other code, such as the analysis code.Type: GrantFiled: April 21, 2003Date of Patent: November 28, 2006Assignee: CSI Technology, Inc.Inventors: Kai Bouse, Todd Reeves

Patent number: 7030747Abstract: A method and system for integrating alarms is provided. An external alarm is received at a process control system and includes an external tag. An internal alarm that is associated with the external alarm is determined based on a map. An internal tag associated with the external tag is also determined based on the map. The process control system generates the internal alarm which includes the internal tag and is based on the external alarm. A method and system for generating alarm and tag relations is also provided. At least one external tag associated with an external system is selected. At least one internal tag associated with a process control system related to the external tags is determined. At least one entry in a map is generated to indicate a relation between at least one of the external tags and at least one of the internal tags. At least one external alarm associated with the external system is selected and at least one internal alarm related to the external alarms is determined.Type: GrantFiled: February 26, 2004Date of Patent: April 18, 2006Assignee: Fisher-Rosemount Systems, Inc.Inventors: Cindy Scott, Robert Havekost, Todd Reeves

Patent number: 6915235Abstract: Information related to an operational condition of a machine in a process plant is generated, where the generated information is in a first data format. The information may be generated based on data in a second format. The second format may, for example, correspond to a format used by a certain type or types of process entities, whereas the first format may, for example, correspond to a format used to process operational condition information of other types of process entities in the process plant. Providing operational condition data for various types of process entities in a common format may, for example, assist an operator in ascertaining the relative importance of the operational condition for various types of entities.Type: GrantFiled: March 13, 2003Date of Patent: July 5, 2005Assignee: CSI Technology, Inc.Inventors: Todd Reeves, Christopher Hilemon, Keith Walton

Patent number: 6839660Abstract: A rotating equipment monitoring device includes a set of sensors, such as temperature, speed, pressure, and vibration sensors, locally connected to a diagnostic unit having a plant communication interface and a processor that implements one or more diagnostic routines. The diagnostic unit collects data from the sensors and performs diagnostics thereon to detect actual or potential problems with the rotating equipment on a continuous or semi-continuous basis. Using the communication interface, the diagnostic unit automatically sends signals indicating detected conditions of the rotating equipment to a maintenance system or a control system via standard or common communication network, such as a HART or Fieldbus network. The diagnostic unit may also be intermittently coupled to an off-line computer, such a one associated with a service provider, who may verify or further define the diagnostics provided by the diagnostic unit.Type: GrantFiled: April 22, 2002Date of Patent: January 4, 2005Assignee: CSI Technology, Inc.Inventors: Evren Eryurek, Kai Bouse, Todd Reeves
