A process plant and industrial control system architecture includes a generalized compute fabric that is agnostic or indifferent to the physical location at which the compute fabric is implemented, includes one or more physical control or field devices located at one or more specific sites at which a product or process is being manufactured and further includes a transport network that securely provides communications between the compute fabric and the pool of physical devices. The compute fabric includes an application layer that includes configured containers or containerized software modules that perform various control, monitoring and configuration activities with respect to one or more devices, control strategies and control loops, sites, plants, or facilities at which control is performed, and includes a physical layer including computer processing and data storage equipment that can be located at any desired location, including at or near a site, plant, or facility at which control is being performed, at a dedicated location away from the location at which control is being performed, in re-assignable computer equipment provided in the cloud, or any combination thereof. This control architecture enables significant amounts of both computer processing and IT infrastructure that is used to support a process plant, an industrial control facility or other automation facility to be implemented in a shared, in an offsite and / or in a virtualized manner that alleviates many of the communications and security issues present in current process and industrial control systems that attempt to implement control with shared or virtualized computing resources set up according to the well-known Purdue model.The industrial control system architecture is protected via more secure and customizable techniques as compared to those used in Purdue model-based control systems. For example, communications between any (and in some cases, all) endpoints of the system may be protected via one or more virtual private networks to which authenticated endpoints must be authorized to access. Endpoints may include, for example, containerized components, physical components, devices, sites or locations, the compute fabric, and the like, and the VPNs may include mutually-exclusive and / or nested VPNs. External applications and services, whether automated or executing under the purview of a person, may access information and services provided by the system via only APIs, and different sets of APIs may be exposed to different users that have been authenticated and authorized to access respective sets of APIs.A configuration system operates within the compute fabric to enable a user to easily make configuration changes to the compute fabric as the user does not generally need to specify the computer hardware within the compute fabric to use to make the configuration changes, making it possible for the user to deploy new configuration elements with simple programming steps, and in some cases with the push of a button.

Systems, apparatus, articles of manufacture, and methods are disclosed for license management of field devices in process control systems. An example apparatus includes interface circuitry; instructions; and processor circuitry to be programmed by the instructions to: identify a field device of a plurality of field devices in a process control system; determine a first version of a license of the field device; and in response to a request to change the first version of the license to a second version of the license: compare the second version of the license to a current version of the license; enable: (1) transmission of the second version of the license to the field device when (a) the second version of the license matches the current version of the license and (b) the field device is communicatively coupled to the processor circuitry; or (2) download of the second version of the license to a transportable memory device when (a) the second version of the license matches the current version of the license and (b) the field device is air-gapped relative to the processor circuitry; and deny either transmission of the second version of the license to the field device or download of the second version of the license to the transportable memory device when the second version does not match the current version.

A process control or automation system configured to control a plurality of process control or automation field devices in a process, includes a compute fabric executing a plurality of instantiated micro-encapsulated execution environments (MEEEs) that cooperate to control the process. Each of the plurality of field devices operates to sense a parameter of the process and output the sensed parameter of the process to an input of the compute fabric and / or to affect a parameter of the process according to an input received from the compute fabric. The system also includes a plurality of digital twin services, each instantiated as one or more of the plurality of instantiated MEEEs, each having an associated one or group of field devices, and each operable to mimic non-physical operation of the one or group of field devices.

The application relates to the technical field of industrial automation, and particularly discloses a layered data interaction industrial measurement and control method, which binds field sensors and actuators through an embedded control module, collects equipment operation data, and executes local autonomous process control logic. When communication is abnormal or interrupted, the embedded control module stores event data and a consistency identifier in a local cache unit to maintain autonomous operation, thereby avoiding system shutdown caused by communication interruption; after communication is restored, breakpoint continuation and integrity check are completed based on the consistency identifier, so that data integrity and business continuity are guaranteed. The layered architecture of software and hardware decoupling provides a standardized data interface to one or more upper software platforms through a data interaction and distribution mechanism, the upper platforms are only used for data display, analysis, reporting or business integration, do not participate in process control, stability, expansibility and adaptability are improved, and the method is suitable for various industrial measurement and control scenes.

Methods for semantic integration of OPC UA information models in a process control system, and corresponding systems and computer readable media. A method (300) performed by a federated information system (200) includes receiving (306), by a first node (202a) of the federated information system (200), a query for desired information from a calling process. The method includes propagating (308), by the first node (202a), a query to a plurality of other nodes (202b, 202c) of the federated information system (200). The method includes identifying (310), by each of the plurality of other nodes (202b, 202c), response information corresponding to the query, and aggregating (312) the response information from each of the plurality of other nodes (202b, 202c). The method comprises: storing (312) the aggregated response information in a mapping knowledge domain of the first node (202a); and returning (314), by the first node (202a), the aggregated response information to the calling process.

An automated spraying method for manufacturing thermal barrier coatings on multi-dimensional complex components is disclosed, relating to the field of thermal barrier coating preparation technology. This invention addresses the problems of existing methods, such as reliance on manual intervention in process transitions and lack of real-time feedback in process control. The invention involves pre-blasting protection of the component's film pores: a Teflon wire of a first diameter is inserted into the film pores, with a first length reserved on the inside; the component's spraying area is roughened by sandblasting; the pre-blasting protective material is removed, and pre-coating protection is applied: a Teflon wire of a second diameter is re-inserted into the film pores, with a second length reserved on the inside; an automated spraying program is used for the undercoat spraying, during which the workpiece temperature is monitored in real time and controlled within a predetermined temperature range, and the undercoat spraying is completed in one pass; after the undercoat spraying is completed, the thickness is measured; an automated spraying program is used for the topcoat spraying; and both the undercoat and topcoat coatings are heat-treated. This invention is used for thermal barrier coating spraying.
