Invensys Ltd. is a multinational engineering and information technology company headquartered in London, United Kingdom. It was formed in 1999 through the merger of BTR plc and Siebe plc. It has offices in more than 50 countries and its products are sold in around 180 countries. It was taken over by the French multinational Schneider Electric for a total consideration of £3.4 billion in January 2014. Schneider plan to replace the "Invensys" name with their own, therefore the "Invensys" brand name shall be phased out. Invensys lines of business are grouped into four segments: Software, Industrial Automation, Energy Controls and Appliance. Its brands include Avantis, Eurotherm, Foxboro, IMServ, InFusion, Triconex, SimSci, Skelta, Wonderware, Drayton, Eberle, Eliwell. Wikipedia.

A well test system for testing fluids produced from one or more petroleum wells has a separator and a plurality of multiphase flow metering systems, each of which has the capability, over at least a portion of its operating envelope, of separately measuring flow rates of oil, water, and gas. The well test system has a fluidic system, including gas leg conduits coupling the separator to the multiphase flow metering systems, liquid leg conduits coupling separator to the multiphase flow metering systems, and bypass conduits for directing multiphase fluid to the multiphase flow metering systems while bypassing the separator. Valves are configured to selectively route fluid flow though the fluidic system to selectively bypass the separator when the multiphase flow metering systems can be used to provide separate flow rates of oil, water, and gas in the unseparated multiphase fluids from the well.

Systems and methods for providing a dynamically synchronized instance to a network device. A repository database stores a process model instance having a layout defined by data elements. A design tool processor coupled to the repository database provides the instance to a user device and a network device. The user device modifies data elements of the instance to generate a first version instance, and the design tool processor generates a dynamically synchronized instance for storing and serving the dynamically synchronized instance to a network device.

Systems and methods for generating an event-based data set using a computer implemented asset monitoring system are provided. An asset repository stores data related to one or more commissioned assets of an asset monitoring system. When event data is received from an asset, whether an asset maintenance record corresponding to the asset exists in the asset repository is determined based on comparing the data in the asset repository to the event data. When the asset maintenance record is determined to not exist in the asset repository, an asset identification record corresponding to the asset is rendered. The asset identification record comprises the event data and additional asset-related data collected from the asset. An event-based data set is generated based on the asset identification record.


Targeted distributing of reports containing historical process control information to particular user devices via a communications network. A curating service permits assigning a score to each report based on an interest level value of the historical process control information to a user associated with each user device and/or an urgency value of the historical process control information. Routing reports to user devices based on the score raises visibility of the historical process control information without overburdening the communications network.

Systems and methods for generating an alert resolution status based on a contextualized alert. An asset repository stores asset-specific data for interpreting an asset parameter. A diagnostic contextualization component is coupled to the asset repository and generates the contextualized alert by retrieving data in the repository. The component also generates the alert resolution status based on determinations related to the contextualized alert.


Interaction between development environments and runtime environments to ensure that underlying process components are in an acceptable state before deploying application updates. A deploy state monitor in a development environment interacts with runtime values in executing applications to manage deployment requests and states of executing applications.

A thermostatic valve such as a radiator valve for regulating the flow of heated fluid in a pipe comprises sensing means (2) for sensing the temperature of the ambient air and actuating means (5) activated by said sensing means, which in turn actuate a fluid valve. A heat shield (4) prevents or inhibits convected and radiated heat from the heated fluid pipe from entering the area of the sensing means, thereby allowing the sensing means to react to the sensed ambient air.


A multicore system controls devices in a process control system. A primary control processing device having a primary master core and a primary remote core is configured for controlling communications on a first network among a first plurality of devices. The primary remote core is configured for controlling communications on a second network among a second plurality of devices. A shadow control processing device is coupled to the first and second networks for processing redundant communications among the devices. The shadow control processing device comprises a shadow master core and a shadow remote core. The shadow master core is configured for controlling communications on the first network among the first plurality of devices. The shadow remote core is configured for controlling communications on the second network among the second plurality of devices.

A historian interface system provides a graphical representation of tags that represent attributes of a continuous process. A historian system stores the tags and metadata values describing the tags. A display device coupled to the historian system via a communication network displays graphical representations of the tags via display panels and receives selections of the tags. The historian system contextualizes selected tags based on the metadata values describing the selected tag and determines an optimal visualization scheme for the selected tags. The display device displays graphical representations of values of the tags and dynamically determines optimal grouping of the tags based on properties of the display device.


Simulation of process control environments, including dynamic properties, with a modified first-order Taylor series expansion. By using more linear calculations, a physical dynamic property is approximated in less time and with fewer computing resources. By adjusting the approximation to introduce curvature, a physical dynamic property is represented over a wider range than with basic linear series expansions. A comparison to a basic linear first-order series expansion identifies conditions when a rigorous update of a dynamic property is needed.
