本文件提供了与供应商无关的工业数字生态系统架构的要求、规范和指南。它包括一个标准化的连接性和服务体系结构，以及一个标准化的用例体系结构，该体系结构具有指定原子级可重用场景和事件的方法，可用于指定标准化行业用例的特征。 注1:第二业务流程中包含的标准行业用例示例与标准化用例架构一起包含在附录A中。 本文件给出: -适用于石油和天然气、石化、发电、公用事业和其他资产密集型行业的架构指南； -在任何给定时间，工厂、平台或设施的二级业务流程中包含的系统体系、系统（包括硬件和软件）和组件之间的互操作性要求； -指导如何实现和维持这些互操作性要求，以支持同一工厂、平台或设施的运行； -能够使数字生态系统概念专业化的规范，以满足所包括行业中二级业务流程的要求； -指导行业参与者，包括所有者/运营商及其产品和服务供应商，使用基于本文档中包含的规范进行互操作的产品来支持其二级业务流程需求。 注2:本文件主要关注在次要业务流程中发挥作用的系统的互操作性需求，包括图7中确定的领域中的系统。

This document provides requirements, specifications and guidance for an architecture of a supplier-neutral industrial digital ecosystem. It includes a standardized connectivity and services architecture, and a standardized use case architecture with methods to specify atomically re-usable scenarios and events, which can be used to specify the characteristics of standardized industry use cases. NOTE 1 Examples of standard industry use cases included in the secondary business process are included in Annex A along with standardized use case architecture. This document gives: — guidance for an architecture applicable to the oil and gas, petrochemical, power generation, public utilities and other asset-intensive industries; — requirements for interoperability among systems of systems, systems (including hardware and software) and components included in the secondary business process of a plant, platform or facility at any given time; — guidance on how these interoperability requirements are to be achieved and sustained in support of operations in the same plant, platform or facility; — specifications enabling the specialization of a digital ecosystem concept for the requirements of the secondary business process in included industries; — guidance to industry participants, including owner/operators and their product and services suppliers, to support their secondary business process requirements using products, which interoperate based on the specifications included in this document. NOTE 2 This document is focused on interoperability requirements for systems which play roles in the secondary business process, including those in domains identified in Figure 7.
