Abstract: Techniques for previewing an operator display of a process section in a process plant include presenting a process section on a user interface device, where the process section includes a user control for presenting and/or displaying another process section on the process plant display. In response to receiving user input indicative of a request to display a preview of the other process section via the user control, the user interface device presents the other process section while simultaneously presenting the process section in a preview mode. The process sections in the preview mode may be presented side-by-side, above and below each other, in separate display windows, etc.

Abstract: A method of communication in a vehicle network is provided. An example method includes transmitting a network allocation map in a TDMA cycle, indicating reservation of time slots in the TDMA cycle. The method further includes transmitting a synchronization signal in the TDMA cycle, to synchronize the timing of nodes in the vehicle network. Each of the reserved time slots is identified by at least a network ID of a transmitting node in the vehicle network, and a slot type comprising one of a low latency traffic slot, and a bulk traffic slot. Further, the low latency traffic slots are repeated in the TDMA cycle at least as frequently as a guaranteed QoS latency parameter. Further, the bulk traffic slots are at least as long as a guaranteed QoS throughput parameter.

Abstract: Techniques for configuring layouts and display view hierarchies and presenting display views in an operating environment of a process plant according to the layouts and display view hierarchies include providing graphical user controls at a graphical display configuration application for defining a layout. The layouts indicate a manner in which divide one or several display screens into one or several display regions, where each display region presents a display view that includes indications of process control elements. The graphical display configuration application also includes graphical user controls for defining a display view hierarchy of the display views by assigning levels of detail to the display views and designating some of the display views as subviews of other display views. An operator application obtains the defined layout and display view hierarchy and presents the display views at an operator workstation according to the obtained layout and/or display view hierarchy.

Abstract: The present invention relates to the furanochalcone class of compounds of general formula A. The present invention particularly relates to the synthesis of furanochalcones and their CYP1A1, CYP1A2 and CYP1B1 inhibitory activity. In addition, the invention relates to the prevention or treatment of cancer caused by polyaromatic hydrocarbons (PAHs), 4-nitroquinoline-1-oxide, and N-nitroso-N-methylurea, heterocyclic amines, estrogen and 17?-estradiol, resulting from the inhibition of CYP1A1, CYP1A2 and CYP1B1 enzymes.

Abstract: The described techniques enable plant personnel to avoid the time and labor-intensive process associated with traditional design systems by enabling users to design, test, and “preview” control logic for controlling a process before downloading the control logic to a configuration database or process controller in the plant. This enables the quick testing and improvement of control logic during the design phase, avoiding the time-consuming iterative process of designing, downloading to a database, propagating to a live controller, and testing on the physical controller. It also separates testing of logic and non-logic aspects of a controller configuration, enabling a user to finish designing the control logic before downloading the configuration to the controller, where she only needs to test non-logic aspects of the configuration.

Abstract: A method and system of aggregating and converting data in a vehicle network is provided. An example method includes receiving a plurality of streams of sensor data over two or more Camera Serial Interface (CSI). The method further includes rearranging the plurality of streams of sensor data into an aggregate stream. The method further includes packetizing the aggregate stream by arranging transmission format bits at appropriate bit positions of the aggregate stream to form a packet data stream. The method further includes transmitting the packet data stream over a vehicle on-board packet data link.

Abstract: Techniques for reconciling discrepancies between the runtime operation of a process plant and the configuration for the process plant allow for the process plant to be operated in a predictable and consistent manner. Additionally, techniques for reconciling discrepancies in the process plant enable inappropriate parameter values to be detected and reconciled efficiently and before such inappropriate values are included into configuration. Such techniques reduce the risk of downtime for online operation of the process plant to troubleshoot object configuration. A configuration engineer may provide one or more reconciliation instructions to reconcile the discrepancy. A configuration application then updates the process control environment of the process plant in accordance with the one or more reconciliation instructions. In some cases, the discrepancy is resolved by updating a configuration file for the object. In other cases, the discrepancy is resolved by updating the runtime instantiation of the object.

Abstract: Disclosed herein are techniques for automatically distributing device identification amongst components of a process control loop in a process plant while the loop is communicatively disconnected from the plant's back-end environment or control room. A field device's identification is stored in a memory of a component of the loop (which may be the field device or a proxy) and is used for commissioning the field device. While the loop remains disconnected, the field device's identification is distributed to the memory of another component of the loop and used for commissioning a portion of the loop including the field device and the another component. Additional distribution to other components for commissioning other loop portions is possible. Distribution may be triggered by the completion of certain commissioning activities, the establishment of communicative connections between components, and/or other conditions.

Abstract: The described methods and systems give users situational awareness regarding control loops in a process control system. The user can utilize the loop interface described herein to quickly understand how a given element (e.g., a device or function block) relates to other elements of the control loop. This enables the user to appreciate how modifying a parameter or device, for example, may impact control of the process. The user need not be intimately familiar with the logic associated with a control loop to understand the status of the control loop and its constituent elements. Further, in an embodiment, the user can easily correct certain statuses (e.g., unusual conditions) that arise with respect to the control loop.

Abstract: Systems and methods of configuring process control systems for operating process plants including multi-variable devices are disclosed herein. Multi-variable devices generate data associated with primary parameters and subsequent parameters. To facilitate configuration and use of subsequent parameters within process control systems, new device objects may be generated to represent the subsequent parameters. The new device objects may be generated as child device objects of parent device objects representing the multi-variable devices. Each child device object may also have a unique tag to identify the new device object within the process control system. The subsequent parameters of the multi-variable devices may thus be used within the process control system by reference to the tags of the corresponding child device objects.
