Abstract: A computer-readable storage medium for controlling a process plant includes instructions operable to determine the location of a device in the process plant and to display data related to proximate devices. The instructions cause a processor to transmit to a server a first request for first data from a data storage area and to receive from the server, in response to the first request, first data from the storage area. The instructions cause the processor to cause the display to display the first data received from the server and to receive an indication that the mobile user interface device is in proximity to an external device. The instructions cause the processor to transmit to the server a second request for second data according to the received indication and to receive second data from the server.

Abstract: User interface sessions in a user interface device are initiated or resumed according to a device type and a target session. A session request is received from a first client device. A device type associated with the session request is determined, and a graphical user interface configuration is identified according to the device type. A target session associated with the session request is identified and a new session is configured for the first client device according to the identified graphical user interface configuration and the identified target session. Data associated with the new session are transmitted to the first client device.

Abstract: A mobile device for context-sensitive operation in a process control environment, and a system including such a device, includes a first circuit for acquiring information associated with a process entity in the process control environment. The mobile device also includes a processor, communicatively coupled to the first circuit, for identifying the process entity based on the acquired information. Further, the mobile device includes a network interface, communicatively connected to the processor, for receiving work item data associated with a process entity. The work item data indicates a target function associated with the process entity. The processor triggers an event to facilitate implementing the target function associated with the process entity in response to the proximity of the mobile device to the process entity and the work item data.

Abstract: In a process plant, a mobile device detects a physical phenomenon and converts the detected physical phenomenon to digital data representative of the physical phenomenon. The data are transmitted to an expert system and analyzed by the expert system to determine a state of one or more process elements. Abnormal conditions associated with the process elements may be detected, and a cause of the abnormal condition may be determined from the digital data. Process control parameters may be automatically changed to correct the abnormal condition, work items may be created to cause personnel to take action to correct the abnormal condition, and/or an operator may be prompted to take a corrective action to resolve the abnormal condition.

Abstract: A supervisor engine cooperates with an expert system in a process control environment to automatically generate, assign, track, and manage work items. The supervisor engine creates work items according to data received from the expert system, selects available personnel to execute work items, sends work items to the selected personnel, schedules the execution of the work items, and creates and stores permissions that allow the assigned personnel to complete a target function of the work item at an assigned time. The supervisor engine determines required skill sets, roles, certifications, and/or credentials associated with a work item, and selects personnel to perform the work item according to a personnel profile specifying a skill set, a role, certifications, and/or credentials associated with the personnel. Alternatively or additionally, the supervisor engine assigns a work item according to the presence of personnel at or near the target equipment.

Abstract: A method or apparatus automatically configures a control module for synchronous execution on a Fieldbus segment of a process control network by determining if all of the critical function blocks of a particular control module can be assigned to FOUNDATION® Fieldbus field devices or to the I/O device associated with a particular Fieldbus segment. If so, the method or apparatus automatically assigns the function blocks of the control module, which would otherwise be scheduled to execute in a controller, to the I/O device for the Fieldbus segment. This technique enables all of the critical or necessary function blocks within the control module to execute in one macrocycle of the Fieldbus segment, thereby executing synchronously on a Fieldbus segment.

Abstract: A system and method for managing delivery of a link active schedule has a master link active scheduler and a backup link active scheduler communicatively coupled together via a databus. The system and method stores a link active schedule in a master link active scheduler and automatically transmits the most current link active schedule from the master link active scheduler over the databus to the backup link active scheduler upon receipt of the link active schedule in the master link active scheduler.

Abstract: A wiring fault detection, diagnostic and reporting technique enables linking devices within a process control system to measure the electrical characteristics of a segment protocol bus and the electrical characteristics of the signals transmitted via the protocol bus. The technique connects a signal line of a segment protocol bus to one of a plurality of measurement blocks within a wiring fault detection unit. The one of the plurality of measurement blocks measures an electrical characteristic associated with the segment protocol bus and sends the measured electrical characteristic to a wiring fault diagnostic manager. The wiring fault diagnostic manager analyzes the measured electrical characteristic to determine a type of the wiring fault and reports the type of the wiring fault via a user interface.

Abstract: A system and method configures a communication link in a process control system having a controller connected to an I/O device via a remote I/O communication link, which has a local and a remote I/O interface communicatively coupled via a remote I/O communication bus. The system and method specifies a remote connection between the controller and the I/O device, recognizes that the remote connection requires communications over the remote I/O communication link, and automatically generates communication objects to route communications between the controller and the I/O device via the remote I/O communication link.

Abstract: A system and method for interfacing a plurality of field devices which are communicatively coupled on a communication network via a standard communication protocol with a process control system uses a linking device to seamlessly integrate communications between the field devices and a controller within the process control system. The system and method uses the linking device to emulate the communication characteristics of the field devices to link information in field devices with information in a controller of the control system, thereby allowing control loops to include combinations of function blocks from both the field devices and the controller. The linking device uses a link active schedule to monitor substantially all communications on the communication network connecting the field devices and selectively processes and analyzes the monitored communications.
