企业控制系统集成 第2部分：企业控制系统集成的对象和属性

[中文适用范围]： 本部分 IEC 62264 规定了制造控制功能与其他企业功能之间交换的接口内容，这些内容作为相互关联的信息模型。信息模型表示为相互关联的概念对象模型集合，可用于实现具有逻辑数据和物理数据模型的应用程序。接口中的数据交换范围限定在 IEC 62264-1 定义的层次模型中第 3 级制造操作与第 4 级业务系统之间。本文档的目的是降低与接口实施相关的风险、成本和错误。由于本文档涵盖了众多制造操作和企业领域，且这些领域有许多不同的标准，因此本数据交换标准的语义在概念层面进行描述，旨在使其他标准能够映射到这些语义。为此，本文档定义了一组包含在通用接口中的元素，以及用于扩展实施中接口内容的机制。范围仅限于定义 IEC 62264-1 中定义的交换信息的对象模型和属性。 [外文原描述]： IEC 62264-2:2026 specifies interface content exchanged between manufacturing control functions and other enterprise functions as interrelated information models. The information models are represented as an interrelated collection of conceptual object models which can be used for the implementation of applications with logical data and physical data models. The data exchanges in interfaces are scoped as between Level 3 manufacturing operations and Level 4 business systems in the hierarchical model defined in IEC 62264-1. The purpose of this document is to reduce the risk, cost, and errors associated with interface implementation. Since this document covers many manufacturing operations and enterprise domains and there are many different standards for those domains, the semantics of this data exchange standard are described at a conceptual level intended to enable the other standards to be mapped to these semantics. To this end, this document defines a set of elements contained in the generic interface, together with a mechanism for extending the interface content for implementations. The scope is limited to the definition of object models and attributes of the exchanged information defined in the IEC 62264-1. This third edition cancels and replaces the second edition published in 2013. It is published as a double logo standard. This edition constitutes a technical revision. Due to the extent of the changes and updates, this document cannot ensure backward compatibility to implementations based on older editions. This edition includes the following significant technical changes with respect to the previous edition and ANSI/ISA 95.00.02-2018 (ED3): a) object models are added for the use of interactive communications to notify subscribers about the occurrence of events and to provide context information about the event, making the information exchange more efficient and consistent. The added object models were the operations event model and operations record model. b) operations location model and spatial definition attribute added to allow the description of operation locations. c) operations test model added to define how test specifications and test results are related to testable objects, operations test requirements, actual resource, and work definitions. d) definition of possible measurement uncertainty sub-attributes for all value, quantity and duration attributes defined in this document. e) updated hierarchy scope model. f) removed as separate models in this edition were the models for product definition, production schedule, production performance, and production capability. Their content is covered for all manufacturing operations management categories under operations models. g) object model was added for the operations segment capability as a collection of resources related to other operations models. h) updated relationship name and role name conventions established in 3.3.4 and implemented across all models and associated tables. i) updated all objects’ relationship role table with explicit source and target names. j) updated common header attributes for objects and property objects established in 4.5 and implemented across all models and associated tables. k) updated explanation of the ‘relationships between resource reference objects in operations management information models and resource models. These additional resource relationships are added to all operations management models. l) added an annex explanation for implementation options for specifying values in unit of measurement attribute. m) added an annex explanation for implementation considerations for inheritance and persistence of data exchange object models.
