A work order initiation and tracking system is coupled between various plant asset diagnostic systems and a work or business management system within a process plant. The work order initiation and tracking system includes a user interface that enables a user to review diagnostic data, recommendations, and other information from one or more of the diagnostic systems regarding potential or recommended changes to plant assets, and to initiate the generation of one or more work orders to implement the recommendations or corrections based on information from the diagnostic systems. The work order initiation and tracking system assists the user in generating work orders by tracking and viewing the created work orders associated with various assets in the plant based on previous diagnostic information or recommendations, by enabling the user to copy data or information from the asset diagnostic applications into the work order generation system, by translating or associating asset name and tag data from the diagnostic systems to the work order generation system to assure that the correct assets are identified in the work orders, and by tracking the progress of the work orders sent to and generated by the business and work management system to provide the user with information pertaining to previously ordered work within the plant.

Enhanced work order generation and tracking system

A process control system collects data, or status information, pertaining to assets of a process plant from various sources or functional areas of the plant. The collected information may then be accessed by a user through a user interface routine displaying a graphical user interface to that user's computer. An asset data and search expert tracks user interaction with plant data by, for example, tracking the types of search fields a user most frequently searches with or the type of information a user more frequently browses for. The expert automatically profiles this tracked information to develop user preferences that are later used in personalizing the reporting of asset data, personalizing searching for asset data, and personalizing the results of such searches.

Personalized plant asset data representation and search system

A method of monitoring an entity within a process plant wherein the entity includes a plurality of lower level entities, includes acquiring a plurality of use indices, acquiring a plurality of weighting values, and creating an aggregate use index from a combination of the lower level use indices and weighting values, wherein the aggregate use index represents status information regarding the entity. Each use index pertains to status information regarding one of the plurality of lower level entities, and each weighting value pertains to the importance of a lower level entity among the plurality of lower level entities.

Aggregation of asset use indices within a process plant

A field device includes circuitry to successively measure a parameter related to current drawn by electronics of the field device. The measurements are provided to a prediction engine which calculates a diagnostic output based upon the plurality of current-related measurements. The diagnostic prediction provided by the prediction engine can provide an estimate of viable life remaining for the device electronics. The diagnostic feature provides on-line status of the overall status of the field transmitter.

Electronics board life prediction of microprocessor-based transmitters

A field device includes diagnostic circuitry adapted to measure a characteristic related to a process control and measurement system. The measured characteristic is used to provide a diagnostic output indicative of a condition of the process control and measurement system. The measured characteristic can be provided to a diagnostic module that operates upon the measured characteristic to predict, or otherwise model, a condition of the process control and measurement system.

Diagnostics for industrial process control and measurement systems

Diagnostic circuitry of a process device is used to detect degradation of a resistive element of the process device while the process device remains online, without the use of an additional power source. In addition, once degradation of the resistive element is detected, the diagnostic circuitry can be compensated for automatically. The diagnostic circuitry includes a testing circuit and a processing system. The testing circuit is coupled to the resistive element and is configured to apply a test signal to the resistive element. The test signal heats the resistive element and causes the resistive element to generate a response signal. The processing system compares a change in the response signal to a corresponding reference to detect degradation of the resistive element.

Diagnostics for resistive elements of process devices

A device in a process control system includes an electrical element which has a resistance. Self-heating circuitry coupled to the element provides a self-heating current to determine the self-heating index (SHI) of the element. Diagnostic information about the electrical element is provided based upon the self-heating index.
