标准摘要
[中文适用范围]： IEC 62541-15:2025 描述了利用 IEC 62541 机制交换安全数据的通信层（含服务与协议）。该文档明确了 IEC 61784‑3 中定义的、适用于本安全通信层的功能安全通信原则。此安全通信层专用于安全装置的实施。 注 1：本文档主要针对控制器之间的通信，但设计时已充分考虑扩展至其他应用场景（如 OPC UA 现场层通信）的可行性。 注 2：本文档不涉及电气安全与本质安全方面。电气安全关乎电击等 hazards；本质安全则涉及潜在爆炸性环境中的相关 hazards。 本文档依据 IEC 61508 系列和 IEC 61784-3 关于功能安全的要求，定义了基于 OPC UA 技术在网络参与者之间传输安全相关消息的机制。这些机制可应用于过程控制、制造、自动化及机械设备等多种工业场景。 本文档为合规设备与系统的开发者与评估人员提供指导。 注 3：系统最终达到的安全完整性等级（SIL）声明，取决于该文档在系统中的具体实现方式；仅将本文档实现在标准设备中，不足以使其 qualifies 为安全设备。 [外文原描述]： IEC 62541-15:2025 describes a safety communication layer (services and a protocol) for the exchange of SafetyData using IEC 62541 mechanisms. It identifies the principles for functional safety communications defined in IEC 61784‑3 that are relevant for this safety communication layer. This safety communication layer is intended for implementation in safety devices only. NOTE 1 This document targets controller-to-controller communication. However, easy expandability to other use-cases (e.g. OPC UA field level communication) has already been considered in the design of this document. NOTE 2 This document does not cover electrical safety and intrinsic safety aspects. Electrical safety relates to hazards such as electrical shock. Intrinsic safety relates to hazards associated with potentially explosive atmospheres. This document defines mechanisms for the transmission of safety-relevant messages among participants within a network using OPC UA technology in accordance with the requirements of the IEC 61508 series and IEC 61784-3 for functional safety. These mechanisms can be used in various industrial applications such as process control, manufacturing, automation, and machinery. This document provides guidelines for both developers and assessors of compliant devices and systems. NOTE 3 The resulting SIL claim of a system depends on the implementation of this document within the system – implementation of this document in a standard device is not sufficient to qualify it as a safety device.
