GB/T 20818.11-2026

This standard defines generic data structures and property lists (LOPs) for measuring equipment used in industrial process control, enabling standardized electronic data exchange between manufacturers, suppliers, and system integrators. It is applied in the automation and process industries, such as chemical, oil and gas, and power generation, to facilitate consistent cataloging and procurement of devices like pressure, temperature, and flow transmitters. By providing a common framework for describing device attributes, it supports interoperability and efficient data integration across engineering and maintenance systems.
