摘要： 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. The reports are generally displayed via a user interface routine that enables users to view the status information as a graphical representation having a leg of a normalized spectrum of values for each category arranged in order of the relative consequence, the relative status quality value being identified at a point on the respective leg.

摘要： A system for detecting abnormal situations associated with a heater in a process plant receives statistical data associated with the heater unit. The statistical data is analyzed to detect whether one or more abnormal situations associated with the heater exist. The statistical data may comprise statistical data generated based on pressure variables sensed by one or more pressure sensors associated with a furnace, a stack, a fuel supply, etc., associated with the heater. Additionally, the statistical data may comprise statistical data generated based on temperature variables sensed by one or more temperature sensors associated with the furnace, the stack, etc. If an abnormal situation is detected, an indicator of the abnormal situation may be generated.

摘要： A process variable transmitter with diagnostics based on power spectral density (PSD) analysis of a process variable sensor signal is provided. In one embodiment, the process variable transmitter is a pressure transmitter and the diagnostics are used to diagnose impulse line obstruction or impending obstruction. Other diagnostics are also useful such as diagnosing primary element degradation. The sensor signal is digitized and the digitized signal is transferred into the frequency domain. The power of the frequencies on the sensor signal is examined to provide the enhanced diagnostics. In one aspect diagnostics are generated directly with the sensor PSD data. In another aspect, the PSD analysis is used to tune a filter in order to enhance traditional diagnostic algorithms.

摘要： Enhanced HART device alerts enable HART devices within a process control system to report alarm or alert conditions that are detected within the devices to a system user or operator using a plurality of intuitive device status conditions, each of which corresponds to a different level of severity and each of which may require a different type of response by the system user or operator. The status conditions are consistent with enhanced Fieldbus device alerts and include a condition associated with a failure of a HART device, a condition associated with maintenance needed by a HART device and an advisable action in connection with a HART device.

摘要： An emergency shut down valve is operated using a pressurized fluid. A pressure transmitter is operably coupleable to the source of pressurized fluid and is configured to receive an indication relative to emergency shut down valve diagnostics. The pressure transmitter responsively captures pressure readings relative to the source of pressurized fluid for a selected duration. In some embodiments, the pressure transmitter may perform diagnostics upon the captured data. In other embodiments, the captured data is provided to an external device for analysis.

摘要： 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.
