IEC 62859:2016+A1:2019提供了一个框架来管理核电站（NPP）系统的安全和网络安全之间的相互作用，同时考虑了解决这些问题的当前IEC标准以及核I&C可编程数字系统的具体情况。本标准建立了以下要求和指南: -将网络安全条款纳入核I&C架构和系统，这些架构和系统从根本上为安全而定制； -避免安全和网络安全条款之间的潜在冲突； -帮助识别和利用安全和网络安全之间的潜在协同作用。 该合并版本由第一版（2016年）及其修正案1（2019年）组成。因此，除了本出版物之外，没有必要下令进行修订。

IEC 62859:2016+A1:2019 provides a framework to manage the interactions between safety and cybersecurity for nuclear power plant (NPP) systems, taking into account current IEC standards addressing these issues and the specifics of nuclear I&C programmable digital systems. This standard establishes requirements and guidance to:
- integrate cybersecurity provisions in nuclear I&C architectures and systems, which are fundamentally tailored for safety;
- avoid potential conflicts between safety and cybersecurity provisions;
- aid the identification and the leveraging of the potential synergies between safety and cybersecurity.
This consolidated version consists of the first edition (2016) and its amendment 1 (2019). Therefore, no need to order amendments in addition to this publication.
