Introduction

0.1 Overview

Only when the information of both parties is exchanged and the use of the information is clearly stated, can the company, business system, and engineering tools be able to proceed smoothly.

And the product data exchange between control systems (electrical, measurement and control technology).

Customers will put forward various requirements for control equipment, and at this time they require suppliers and manufacturers to choose appropriate equipment. In the past, suppliers would

Describe the device according to its own file format, usually using different terms, structures and media (paper, database, CD-ROM, electronic catalog, etc.). This

This situation is very similar to some situations in the planning and development process, that is, equipment information is often used in many different information technology systems.

Reference.

Any method, if it can record all the necessary information of the equipment during planning, ordering and use, and enable it to be used for further

The treatment of these factors can provide all relevant parties with the possibility of paying attention to these elements. The prerequisite for this method is the object description and information exchange

standardization.

The GB/T 20818 series of standards proposes a standardized method that helps suppliers and users of measurement equipment to optimize internal and

Work flow between companies. Depending on the role in the process, the engineering company can be considered a user or supplier.

This method specifies process control equipment through attribute blocks. These attribute blocks are combined into attribute lists, where each list describes a specific

The type of equipment (device). The attributes included in this series of standards can be used to query or set equipment in computer systems and other task systems.

Into the required program or detailed performance.

In order to facilitate automatic data exchange between two computer systems in any workflow, IEC 61987-10 defines

And the structural elements of the performance structure list of process control equipment, such as the workflow of engineering, maintenance or procurement, and allow customers and equipment suppliers

Optimize their processing and workflow. IEC 61987-10 also provides a data model for assembly attribute lists.

IEC 61987-11 specifies the general structure of measuring equipment, and provides several important details, such as the processing of composite equipment.

The description of the attribute list of industrial automatic valves is also required. This section specifies the operating attribute list and equipment attribute list of industrial automatic valves

The general structure of the table. Industrial automatic valves are also called final control elements and include control valves, automatic on/off valves and process regulators. This part of regulation

The structure of the subsequent parts of this series of standards is defined. These subsequent parts will specify the completeness of the final control elements with different structures and functional principles.

LOP. This general structure can be used as the basis for other industrial process control instrument type LOP specifications.

0.2 Device type dictionary

Appendix A gives the characteristic description of the final control element. This is a tree describing the relationship between different device types. From the root

The "Industrial Process Automation Device" started, introducing the final control components. In addition to control valves, actuators and accessories, such as positioners, also belong to

This group. These feature descriptions are used in the process automation field of the IEC Common Data Dictionary (CDD).

1 Scope

This part of GB/T 20818 stipulates.

* The Common Data Dictionary (CDD) has a collection of various automatic valves, including the characteristics of control valves, automatic on/off valves and process regulators

description;

* Compliant with IEC 61987-10, the common operation attribute list (OLOP) and equipment attribute list (DLOP) of the final control element

structure.

The general structure of OLOP and DLOP contains the most important blocks for the final control element. The relevant blocks for a specific device type are in

Described in other parts of the IEC 61987 series of standards. Similarly, this section does not involve device attributes. For example, globe valve and quarter stroke

The OLOP and DLOP of the valve are specified in IEC 61987-22.

Note. In the classification (see Figure 1), the "final control element" has only special automatic valves and process regulators. In practice, there are other specialized equipment
