Only when the information exchanged and the purpose of the information are clearly defined, the company, business systems, engineering tools, internal company data systems and Only then can product data exchange between future control systems (electrical, measurement and control technology) proceed smoothly. In the past, users would make various requirements to suppliers or manufacturers when purchasing equipment, and suppliers would describe these equipment according to their Their own file formats, often using different terminology, structures and carriers (paper, databases, CD-ROMs, electronic catalogs, etc.). This situation and regulations Similar to some situations in the planning and development process, device information is often used in many different information technology systems. There are many types of equipment, each with different attributes (including equipment attributes and operating attributes, etc.). In order to record the equipment at one time, it is important to plan and order the equipment. As well as all necessary information in the later use process, all relevant parties should pay attention to these elements, and GB/T 20818 "Industrial Process Measurement" is specially formulated. and data structures and elements in the control process equipment catalog to describe different equipment and standardize the exchange of information. GB/T 20818 proposes a standardized approach that helps suppliers and users of measurement equipment optimize their performance within and between companies. workflow. Depending on the job or functional role in the process, engineering companies may be considered users or suppliers. This method specifies the Customized process control equipment. These attribute blocks are combined into attribute lists, each of which describes a specific device (device) type. GB/T 20818 includes attributes that can be used for queries or proposals as well as those needed to integrate the device into a computer system to perform other tasks. Detailed properties. GB/T 20818 is intended to consist of the following parts.

1.Measuring equipment with analog and digital outputs. Specifies communication for process measurement equipment with analog and digital outputs Using a collection of structures and product characteristics, the purpose is to provide guidance for the formulation of standards for different types of process measurement equipment.

10.Basic principles of List of Properties (LOPs) for electronic data exchange for industrial process measurement and control. The purpose is Specifies the basic principles of operating attribute lists (OLOP) for electronic data exchange of measuring equipment, and provides the data model of OLOP.

1 Scope

GB/T 20818.14-2023 is Part 14 of the Chinese series on data structures in process equipment catalogues, and gives the lists of properties for temperature measuring equipment. A temperature measurement is an assembly rather than a device - sensor, sheath, thermowell, extension and transmitter - and the properties that decide whether it will work in a given service are spread across all of them: the sensor type and class, the immersion length, the wetted material, the response time and the process connection. Comparing catalogues by hand across those dimensions is what the property list removes. The standard sets the general provisions and the description of the object and device lists of properties, with a normative annex giving the full property list for temperature measuring equipment. It took effect on 1 March 2024.

This document specifies.

---Operating attribute list (OLOP) used to describe the operating parameters of temperature measuring equipment and a set of requirements for temperature measuring equipment;

---Device Properties List (DLOP) used to describe different contact and non-contact temperature measurement device types. The structure of OLOP and DLOP conforms to the general structure defined in IEC 61987-11 and conforms to the general structure defined in IEC 61987-

10 Basic principles of LOP structure. In addition to OLOP, other aspects required in the different electronic data exchange processes described in IEC 61987-10 have been Published in IEC 61987-92. The attribute library and block library used by LOP in this document are listed in Appendix C and Appendix D respectively.
