摘要： Multi-functional field maintenance (FM) tools that connect to process control devices, such as FOUNDATION Fieldbus and Highway Addressable Remote Transducer devices, can automatically detect and simultaneously identify communications, troubleshoot connections, and supply power in a process control plant. Simplifying the troubleshooting process, by guiding a user of a multi-functional FM tool through recommended troubleshooting steps, while simultaneously detecting and correcting issues reduces the number of tools required to maintain process control devices, reduces the risk of damage, and improves efficiency by minimizing production downtime.

摘要： Techniques for assessing and presenting differences between the current commissioning data of a set of process control devices within a process plant and the respective baseline or defined commissioning parameters of the set of process control devices. According to embodiments, systems and methods may obtain the current commissioning data from the set of process control devices and access baseline parameters corresponding to the commissioning data. The systems and methods may compare the current commissioning data to the baseline parameters to determine a set of differences, and present, via a user interface, the set of differences for review by an administrator. In reviewing the set of differences, the administrator may facilitate different functionalities including rebaselining or reconfiguring process control devices.

摘要： A display configuration system enables plant operators to create their own process displays called dashboards during run-time of the plant and in the same interface that these operators use to view operation of the process plant. This display configuration system makes the operators more productive because the operators can quickly create and implement their own specialized dashboards, as these operators determine these dashboards are needed. Each dashboard has a defined layout specifying locations or regions at which display elements can be shown in the dashboard, and this layout is operator modifiable. Operators can easily create content on their own dashboards using predefined but configurable display building blocks called gadgets, which can be pre-stored in a library and can be made available for the operator during dashboard creation activities. A gadget can be dragged and dropped onto a dashboard at one of the regions or locations of the dashboard to be installed in that region or location of the dashboard. The display configuration system may automatically size the gadgets based on the selected dashboard layout, and operators can modify an existing dashboard by adding, modifying, moving, minimizing or deleting gadgets on the dashboard.

摘要： Negating effects of continuous introduction of risk in scoring the health of a process control system includes automatically and periodically assessing a risk for each of the process control systems, calibrating the center of a health score scale to the average risk assessments, and scoring the health of each process control system within the health score scale according to a nonlinear scale applied to the risk assessment. Introduction of a risk factor to a process control system increases the risk assessment, and elimination of a risk factor decreases the risk assessment. The same risk factor introduced to each of the of process control systems does not affect the health score of any process control system, and elimination of a risk factor has more of an effect on the health score towards the center of the health score scale than towards upper and lower limits of the health score scale.

摘要： A maintenance system for a process plant collects and uses historical data about maintenance orders. The data identifies the maintenance items for completing an order, such as the labor, materials, and maintenance tasks required. The data is historical data developed from actual completed maintenance orders. The system uses archived historical data and estimates various maintenance information, such as estimated cost for completing the maintenance order, and estimated start and completion times. The estimated data may be based on averaged data as a result. This estimated data along with the other maintenance order information may be sent to a scheduler for identifying a priority to the maintenance order and scheduling it accordingly.

摘要： Methods and apparatus for using analytical/statistical modeling to perform continued process verification (CPV) are described. Example methods include determining distribution characteristics for a plurality of parameters based on a first historical batch dataset measured while manufacturing a first batch at a first time, and generating a model batch based on the distribution characteristics of the plurality of parameters. Example methods also include generating a first set of simulated batch datasets corresponding to a first set of simulated batches by, for each one of the first set of simulated batches: generating values for the plurality of parameters based on the model batch, and determining a quality prediction based on the generated values. The example methods also include generating a model based on the first set of simulated batch datasets and the first historical batch dataset. The model is to be implemented to monitor a subsequent manufacture of a second batch.

摘要： An I/O-abstracted configuration is defined for a field device that has not yet been assigned or allocated to communicate via a particular I/O device, and the field device (and optionally portions of the process control loop of which the field device is a part) is commissioned based on contents of its I/O-abstracted configuration. The field device's I/O-abstracted configuration is stored in an instance of a device placeholder object, which may be common to multiple types of devices and multiple types of I/O. A property of the device placeholder object may be exposed based on the value entered for another property, and the device placeholder object may store abstracted values as well as explicit or discrete values that are descriptive of the field device and its behavior. Upon I/O-assignment or allocation, values held in the device's I/O-abstracted configuration may be transferred to or otherwise synchronized with the device's as-built configuration.

摘要： During commissioning activities of a process plant, a device placeholder object that stores an I/O-abstracted configuration of a particular field device within the plant is created and stored in a device in the back-end environment of the plant and a further configuration file is stored in or for the particular field device in the field equipment environment of the plant. The device placeholder object, which will eventually be associated with the particular field device, and the field device configuration file are used to perform separate commissioning activities in each of these plant environments before the field devices are configured to communicate with a process controller via a particular I/O network within the plant. Thereafter, a binding application performs a discovery process to detect the I/O communication path through which each field device is connected to the back-end environment. The discovery process traverses through the I/O network as built, and autosenses the devices within the I/O network until this process discovers a device placeholder object or a configuration file for a particular field device. The binding application then determines if the information within these two device configuration files match, and if so, binds the field device to the back-end by storing the detected communication path for the particular device in a configuration database, such as in the device placeholder object for the particular field device. If the configuration information in the device placeholder object does not match the configuration file for a discovered field device, the binding application may perform a reconciliation procedure to determine the correct configuration information for the particular field device.

摘要： A method and system configures a Device Description Language (DDL) interface on a DDL-based host system in a process plant. Using a device description identification, the system and method updates the host system with the device description for a selected process control device. The device description includes menus for the selected process control device. The method and system expose the DDL menu constructs from the device description to the host system, such that the host system is able to present the DDL constructs as user-selectable elements in a configuration interface, where DDL constructs may be added, deleted and/or modified to create a DDL interface independent of the menu for the process control device as provided in the device description.

摘要： A method of controlling and managing a process control system having a plurality of control loops includes implementing a plurality of control routines to control operation of the plurality of control loops, respectively, wherein the control routines may include at least one non-adaptive control routine. The method then collects operating condition data in connection with the operation of each control loop, and identifies a respective process model for each control loop from the respective operating condition data collected for each control loop. The identification of the respective process models may be automatic as a result of a detected process change or may be on-demand as a result of an injected parameter change. The process models are then analyzed to measure or determine the operation of the process control loops.
