The portable field maintenance tool may interact with field devices configured according to a number of different communication protocols, such as the HART protocol and the Fieldbus protocol. The portable field maintenance tool may be energy limited and fault tolerant, and may operate in compliance with Intrinsic Safety standards, enabling use of the portable field maintenance tool in hazardous areas.

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: Methods and apparatus to communicatively couple on/off valves to controllers in a process control system are disclosed. An example apparatus includes a first interface to receive a command signal from a termination module to be communicatively coupled to a controller in a process control system. The command signal is directed to an on/off valve in the process control system. The first interface transmits a feedback signal to the termination module in response to the command signal. The example apparatus also includes a second interface to receive position information from proximity sensors in a switch box monitoring a state of the on/off valve. The feedback signal is based on the position information. The example apparatus further includes a communication processor to be communicatively coupled to the first and the second interfaces to process the command signal and the feedback signal.

Abstract: Techniques for managing alerts associated with devices of a process control system in a process plant are described.

Abstract: Methods and apparatus for operating a process plant include multiple user interface devices operable to determine the location of the device in the process plant and to display data related to proximate devices. A processor in a mobile user interface device transmits a first request for data and receives the requested data in response to the request. The processor causes a display to display the received data. The processor receives an indication that the mobile user interface device is in proximity to an external device the processors transmits a second request for data according to the received indication. The processor then receives data in response to the second request.

Abstract: Flexible graphic element objects in a process plant are configurable both in a run-time operating environment in which a process is being controlled and in a configuration environment. An instantiated flexible graphic element object may be a display view or may be another graphic element included on a display view. A graphic element object may be linked to and/or derived from another graphic element object, and changes to a particular graphic element object may be propagated to its derivations, e.g., according to a distribution policy. Changes to definitions corresponding to a particular graphic element object (e.g., to the definition of a graphic element attribute such as a shape, animation, event handler or property) may be overridden or modified in another object derived from the particular graphic element object. The modified derived object may be renamed and saved separately from the particular graphic element object.

An example apparatus includes an I/O module to be electrically coupled to a field device via a terminal block, the terminal block including a surge protector to reduce an input voltage to an operating voltage when the input voltage satisfies a first threshold, and a communication interface to generate a status message when the input voltage satisfies the threshold.

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: A data analytics service for performing data analytics functions within a distributed process control environment is provided. The service may provide a user interface for creating a first diagram, representing a data model. The first diagram may be configured, compiled, and evaluated using off-line (i.e., historical) data from a distributed process control system, which may include data stored in distributed data engines (DDEs). Following evaluation, the first diagram may be automatically converted into a second diagram that is bound to on-line (i.e., real-time) data sources within the process control environment, which may then be compiled and executed to generate performance or predictive analytics data for the process. The diagrams may comprise a plurality of configurable function blocks or modules, connected logically via wires conveying outputs or inputs of the blocks or modules.

Abstract: A method of providing data from a process control system to remote computing devices includes obtaining, at a data server via a first network from a mobile server, one or more lists including indications of requested process data parameters indicating process data for communication from the server to the remote devices via a second network. The method includes receiving, from a plurality of controllers within the process control system via a third network, a stream of process data parameter values associated with process data parameters included in one or more configuration files. The configuration files describe a configuration of the process control system. The method includes identifying, by processors of the data server, a subset of the received parameter values corresponding to the requested process data parameters of the lists, and communicating, from the data server to the mobile server via the first network, the identified subset of parameter values.

Abstract: Process control systems for operating process plants are disclosed herein. The process control systems include control modules that are decoupled from the I/O architecture of the process plants using signal objects or generic shadow blocks. This decoupling is effected by using the signal objects or generic shadow blocks to manage at least part of the communication between the control modules and the field devices. Signal objects may convert between protocols used by control modules and field devices, thus decoupling the control modules from the I/O architecture. Generic shadow blocks may be automatically configured to mimic the operation of field devices within a controller executing the control modules, thus partially decoupling the control modules from the I/O architecture by using the shadow blocks to manage communication between the control modules and the field devices.

Abstract: An automated method for managing a work flow in a process plant includes determining the steps of performing a work item and generating associated displays for an operator or other personnel to perform the steps of the work item. A work item is created specifying a task to be performed in the process plant and determining from the specified task a set of procedures for execution of the work item. For each procedure, an associated display is generated and the associated displays are displayed on a mobile user interface device sequentially in an order in which the set of procedures are to be performed.

Abstract: A long-haul process control plant includes a process control system which controls industrial processes running within the plant, and a safety instrumented system, servicing the process control system, which detects safety-related problems within the plant and communicates safety messages within and between portions of the process plant, e.g., to effect a trip or other mitigating action. To transmit safety messages between remotely located portions of the process plant via a low-bandwidth long-haul link, a safety data concentrator combines individual safety messages generated by the safety logic solvers disposed at one portion of the plant into a concentrated safety message, and transmits the concentrated safety message to a safety data de-concentrator in the remote portion of the plant.

Abstract: 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 or I/O network within a plant, and this configuration is stored in a device placeholder object in a back-end environment of the plant. Thereafter other objects, modules, applications, user interfaces, etc., that are to execute in the back-end environment of the plant to communicate with the field device during on-line operation of the plant may be designed, built, configured, and tested using the device placeholder object without any actual communications with the field device and without assigning the device placeholder object to a particular I/O channel or I/O network.
