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： A method for configuring a process control system includes coupling an I/O module to a PLC coupled to field devices. For each field device, the PLC has registers storing data of values associated with the field device. The PLC is configured such that each field device is associated with a PLC control tag, and each control tag is associated with tag parameters corresponding to the registers for the field device. The method includes configuring the I/O module to associate the tag parameters with corresponding controller parameters such that, for each control tag, there is a set of controller parameters associated with the tag parameters for the control tag. The method includes instantiating an integration object and associating the integration object with one of the control tags. The integration object configures itself, according to the set of controller parameters that is associated with the tag parameters for the control tag, as an analog input function block, a discrete input function block, an analog output function block, or a discrete output function block.

摘要： 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.

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.

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： A two-wire routing device includes an upstream communication interface for communication with a controller, a two-wire communication and power interface configured to convey communication and power to a field device over a two-wire link, and a router electronic controller. The router electronic controller is coupled to the upstream communication interface and the two-wire communication and power interface. The router electronic controller receives, via the upstream communication interface, a safe state command from the controller, and transmits, via the two-wire communication and power interface, the safe state command to a field device over the two-wire link. The router electronic controller further executes a secondary de-energization scheme for the field device to control a power switch to cut power over the two-wire link to the field device.
