Introduction
0.1 Overview
Product data exchange goes smoothly, whether in companies, business systems, engineering tools, collaborative data systems and future control systems
Between the systems (electrical, measurement, and control technologies), there is a clear definition of the information exchanged and the use of the information.
In the past, when users asked suppliers or manufacturers for suitable equipment, they always asked for process control equipment and systems.
A variety of things. Use their own documentation schemes when it comes to vendors to describe these devices, often using different terminology, structure and
Body (paper documents, databases, CDs, electronic data books, etc.). There are similar situations in the planning and process progress, equipment information is frequently copied
Bay is in a number of different information technology systems to answer user inquiries.
A method for recording all existing data and user follow-up processes during the planning and ordering process is provided to relevant parties.
The way to note these elements. A prerequisite is the standardization of object description and data exchange.
This series of standards proposes a standardized approach that helps suppliers and users of measurement equipment optimize between companies and companies.
Workflow. Depending on the role in the process, the engineering company can be considered a user or supplier.
This method specifies the measurement device based on the attribute block. These attribute blocks are combined into a list of attributes, each of which describes a specific design
Equipment (device) type. This series of standards includes attributes that can be used to query or device integration in computer systems and other task systems.
Required solution or detailed performance.
In order to facilitate automatic data exchange between two computer systems in any workflow, GB/T 20818.10-2017 defines
Structural elements for a list of performance constructs for electronic and process control equipment, such as engineering, repair or procurement workflows and allowing customers and
The supplier optimizes their processes and workflows. Part 10 also provides a data model for the assembly property list.
This part of GB/T 20818 specifies the general structure of the list of operational attributes and device attributes (OLOPs and DLOPs). it
Specifies the framework of the other parts of the GB/T 20818 series of standards for measuring a given physical variable and using specific measurement principles
A list of all the properties of the device type. This general structure can also be used as a basis for an attribute list specification for other industrial process controls.
Instrument type (such as control valves and signal processing equipment).
0.2 attribute list (LOPs) content
The list of attributes specified in this section is described at the overview level as follows.
● measuring the operating conditions of the equipment;
● The environmental conditions of the measuring point;
● measuring the performance of the equipment;
● measurement, mechanical and electrical characteristics of the measuring device;
● Compliance of the measuring instrument to specific industry requirements.
A list of attributes (LOP) maps are structurally real, but do not represent a meter model.
0.3 Configuring the measuring device
The usual list of attributes needs to consider both the integrated device and the standalone installed device.
0.4 device type dictionary
Appendix A of this section describes a measurement device feature based on a step library (ISO 10303). This is a description of different devices
The relationship tree between types. Starting from the "automation device" at the root, it is first based on the type of measuring device and then based on the process variable
Measurement, and finally according to the measurement method. This structure will be used in the IEC Component Data Dictionary (CDD) "Automation Equipment" field.
For the purposes of this section, Chapter 3 identifies and defines the following types of measuring equipment. observation indicators, meters (meters), transmitters, switches, and measurements.
Measuring device.
It should be noted that in the real world, there is no clear demarcation between the types of measuring devices. In the commercial literature, indicators are often referred to as
Table (count), although the product does not provide quantitative measurements. Similarly, direct indication displays are usually equipped with an electrical trip switch that makes the meter (meter) a switch.
Finally, "transmitters" are not a general term, especially flow measurement, which many manufacturers call "instruments."

4 Overview
4.1 Category framework
GB/T 20818.1 is based on the measurement given the category framework of industrial process measurement equipment. Industrial process measuring equipment can be further refined
Divided into observation indicators, meters (meters), transmitters, switches, measuring devices, see the relevant definitions in Chapter 3 of this section. Figure 1 is a block diagram
Explain how the characterization is formed. All features are provided in Table A.1.
It should be noted that when creating a list of attributes for a device, the meter component may be one of an observation indicator, a meter, a transmitter, or a switch.
The observations, gauges, transmitters or switches can be part of a measuring device or a composite device (see 7.1). For clarity
See above, these are not shown in Figure 1.
The enhanced feature framework is used in the IEC Component Data Dictionary (CDD). In CDD, the measuring instrument belongs to the automation device.

4.2 aspects
In addition to describing the attributes of the device's own features in the Device Attribute List (DLOP), the device has different aspects for expressing it.
Related topics. For example, from an operational perspective, the list of operational attributes (OLOP) and its list of device attributes are related to each other.
