--- Changed the scope to include "Electronic Device Description (EDD) technology, which can integrate real product Product Details", deleted "This document only defines a subset of GB/T 21099.1, while GB/T 21099.1 describes Appendix B contains the conformance statement of the conformance statement only with GB/T 21099 this part is relevant. The requirements in GB/T 21099.1 are not included in these conformity declarations" and "This part of GB/T 21099 the classification is also based on GB/T 19769.1 "Abstract Definition" and other contents (see Chapter 1, Chapter 1 of the 2015 edition);

--- Added terms. EDDL processor, EDDL profile, EDD application, incompatibility, proxy, electronic device description technology, electronic Device Description Interpreter, Electronic Device Description Language, Electronic Device Description Language Compiler, Coexistence, Managed Resources, Interoperability, Interoperability Convertibility, interconnectivity, interoperability, models, built-in routines, performance, semantics, preprocessors, preprocessor directives (see Chapter 3);

--- Added "Lexical Structure Conventions" (see 3.3);

---"CommandASE" has been added to the mapping from FB to APO (see Chapter 8).

This document is equivalent to IEC 61804-2:2018 "Function Block (FB) and Electronic Device Description Language (EDDL) for Process Control Part 2 Part. FB Concept Specification.

The following minimal editorial changes were made to this document.

--- In order to coordinate with the existing standards, the name of the standard is changed to "Function Blocks (FB) for Equipment and Integrated Process Control in Enterprise Systems" and Electronic Device Description Language (EDDL) Part 2: FB Concept Specification.

Introduction

GB/T (Z) 21099 is intended to consist 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 configuration files for various fieldbuses.

--- 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 provides conceptual functional block specifications that can be mapped by industrial organizations to standardize communication systems and their associated definitions.

Can be used to specify Electronic Device Description Language (EDDL).

The relationship between GB/T 21099.2 and other standards and products is shown in Figure 1.

For equipment and integrated process control in enterprise systems Function Block (FB) and Electronic Device Description Language (EDDL) Part 2: FB Concept Specification

1 Scope

This document applies to function blocks (FB) for process control.

This document specifies the function block (FB) taking the following factors into consideration.

a) The device model defines the device components that conform to this document.

b) FB concept specification for measurement, execution and processing. It includes general rules for essential features to support control and Details that hinder innovation and specialization in different industrial fields are avoided.

c) Electronic Device Description (EDD) technology, which can integrate real product details using engineering life cycle tools.

Function block standardization combines a variety of existing technologies to define and abstract the characteristics of function blocks in a unique way.

The abstract method of function blocks is called "FB concept specification" in this document. The abstract definition of function blocks can be applied to a specific communication system.

Such as are referred to herein as FB concept specifications and are mapped by industry organizations to specific communication systems and their additional definitions.

NOTE This document can be mapped to ISO 15745-1.

There are many solutions on the market that meet the requirements of this document and show how the conceptual specifications can be implemented in a given technology.

New technologies need to find equivalent solutions (see Figure 4).
