本文件规定了ISO 6165中定义的土方机械（EMM）及其设备中机器控制系统（MCS）安全相关部件的软件开发和信号传输要求的一般原则。此外，本文件还阐述了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机器控制系统输出响应不正确。 网络安全不在本文件范围内。 注:有关网络安全的指导，请参阅适当的安全标准。 本文件不适用于出版日期之前制造的EMM。

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.
