摘要： Generic shadowing allows a shadowing device in a process plant to automatically discover, without pre-configuration or pre-definition, and without the use of a configuration tool, source control objects that are hosted at other devices and that are to be shadowed. Source control objects may utilize any data type, format, structure, language, etc. The shadowing device includes a shadow manager and a set of primitive components defining simple data types that are utilized to discover the configurations/definitions and data types of source control objects, and includes a shadow library in which signatures of discovered source control objects are stored. Signatures are instantiated and used by the shadowing device to provide dynamic data to recipient devices, applications, and/or control objects in the process control system, where the dynamic data is a mirror of data that is observed first-hand by the source control objects during their on-line operations at their host devices.

摘要： An enhanced modular controller is disclosed that includes a plurality of configurable communication ports and a control logic layer operable to control equipment of a process plant. The plurality of communication ports include a first set of communication ports and a second set of communication ports which are operable to communicate with one or more nodes of a distributed control system of the process plant. The enhanced modular controller also includes a software layer that accepts port configuration parameters that define one or more port communication rules for the first set of communication ports and for the second set of communication ports. The one or more port communication rules causes the software layer to selectively allow or restrict retransmission of incoming messages, where the incoming messages are received at the first set of communication ports or the second set of communication ports.

摘要： An alarm handling and viewing system includes an alarm display interface that enables the different alarms generated by the same control module, safety system module, device, etc., to be handled and viewed in a manner that is different than each other and/or that is different than the display parameters specified for the module or device that generates the alarms. The system thus enables the selection of various different alarms of a single control module, device, etc., to result in different plant displays, different faceplate displays, and/or different alarm handling parameters to be used to provide further information to the user regarding the selected alarm. This feature, in turn, enables the alarm handling and viewing system to immediately switch to a predetermined plant display, faceplate display, or detail display best suited to the individual alarm being viewed, to thereby enable a control operator to more quickly identify the source or cause of an alarm and/or to determine a cause of action to take in responding to the alarm.

摘要： Methods and apparatus to detect root causes of alarm patterns in process control systems are disclosed. An example method includes retrieving process control data generated in a process control system during a historical period of time. The process control data includes alarm data associated with alarms activated during the historical period of time. The example method also includes generating an alarm activation timeline for the historical period of time. The alarm activation timeline includes icons representative of the alarms to visually represent a temporal relationship of activation of the alarms, where one of the icons is representative of an alarm that is no longer active. The example method further includes storing the alarm activation timeline in a database.

摘要： Methods and apparatus to configure process control systems based on generic process system libraries are disclosed. An example method includes instantiating an instance of a generic process system library. The instance is associated with items of equipment and corresponding process signals of a process control system. The generic process system library comprises at least one of generic process graphic data or generic control strategy data corresponding to the items of equipment and the corresponding process signals of the process control system. The example method further includes configuring the instance of the generic process system library by incorporating process-specific data associated with the operation of the process control system with the at least one of the generic process graphic data or the generic control strategy data.

摘要： Techniques for controlling the operation of a process plant or several process plants within a process control system using a centralized or distributed controller farm allow for increased flexibility in the process control system. Any of the controllers in the controller farm may be utilized to execute modules corresponding to any of the field devices in one or several process plants. Control modules or other operations may be allocated amongst the controllers distributing the load so that one controller is not performing several operations while others are inactive. Additionally, the controller farm may be located in a temperature controlled room or area in an offsite location from the process plants. In some scenarios, load balancing techniques are performed to distribute the load for the modules equally or at least similarly amongst the controllers.
