Introduction

GB/T (Z) 21099 consists of the following 6 parts.

--- Part 1: General introduction to system aspects. The purpose is to provide suppliers with general guidelines and specifications to ensure that users can select compatible equipment.

compatibility, interoperability, and interchangeability.

--- Part 2: FB concept specification. The purpose is to provide conceptual function block specifications, including. device model of device components;

conceptual specification of the FB for measurement, execution, and processing, including general rules for supporting essential features of control to avoid impeding innovation New details and specialized details for different industrial fields; Electronic Device Description (EDD) technology, using engineering life cycle tools Tools to integrate real product details.

--- Part 3: EDDL syntax and semantics. The purpose is to specify the Electronic Device Description Language (EDDL) technology, which allows the use of industrial the integration of actual product details is accomplished through tools in the process life cycle.

--- Part 4: EDD interoperability. The purpose is to ensure that field device developers use the EDDL structure consistently. It supplements EDDL specification to promote interoperability and portability between EDDL applications Plant nature.

--- Part 5: EDDL built-in library. The purpose is to define the EDDL built-in library and provide various fieldbus specifications.

--- Part 6: Meeting the needs of field device engineering tools for integrated fieldbus devices. The purpose is to provide equipment and system manufacturers with it provides guidance for manufacturers to use EDDL technology to meet user needs, and also provides guidance for system integrators and instrument maintenance personnel.

Provides guidance to help end users integrate systems and incorporate device management into their workflow using EDDL technology.

This document contains.

---Overview of using EDDL;

--- Provide EDDL examples and demonstrate how to use them;

---Describe how to implement the use case;

---Explain the correct application of EDD for each example.

This document is not a guide to EDDL, nor is it intended to replace the EDDL specification.

This document provides instructions for EDD applications. These instructions describe how to perform operations when the technology used in the host implementation is not specified.

For example, the FILE structure describes the data stored by the proxy EDD application on behalf of the EDD. The FILE construct does not specify data.

The EDD application can use a database, a plain file, or any other format of its choice.

EDDL functions are subject to the profile of each communication technology. The descriptions in this document refer to these functions in a general sense and are not intended to be exhaustive.

All communication technologies will support all the functions described. In order to understand the features supported by each communication technology, reference is made to GB/T 21099.3 the line definition in.
