土方机械.功能安全.第4部分:控制系统安全相关部分的软件和数据传输的设计和评估

[中文适用范围]： 本文件规定了土方机械 (EMM) 及其设备中机器控制系统 (MCS) 安全相关部分的软件开发和信号传输要求的一般原则，如 ISO 6165 中所定义。 此外，本文件还讨论了ISO 12100 中定义的与机器控制系统中嵌入的软件相关的重大危险。 正在解决的重大危险是来自机器控制系统输入的不正确的机器控制系统输出响应。 网络安全不属于本文档的范围。 注：有关网络安全的指导，请参阅相应的安全标准。 本文件不适用于其发布之日之前生产的 EMM。 [外文原描述]： This document specifies general principles for software development and signal transmission requirements of safety-related parts of machine-control systems (MCS) in earth-moving machinery (EMM) and its equipment, as defined in ISO 6165. In addition, this document addresses the significant hazards as defined in ISO 12100 related to the software embedded within the machine control system. The significant hazards being addressed are the incorrect machine control system output responses from machine control system inputs. Cyber security is out of the scope of this document. NOTE For guidance on cybersecurity, see an appropriate security standard. This document is not applicable to EMM manufactured before the date of its publication.
