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.

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.

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.
