IEC 62279:2015规定了铁路控制和保护应用中使用的可编程电子系统软件开发的过程和技术要求。它旨在用于任何有安全问题的领域。这些系统可以使用专用微处理器、可编程逻辑控制器、多处理器分布式系统、更大规模的中央处理器系统或其他架构来实现。与上一版相比，主要技术变化如下: -增加关于软件管理和组织、角色和能力的定义、部署和维护的要求； -根据IEC 61508-2:20 10增加了关于工具的新子条款。

IEC 62279:2015 specifies the process and technical requirements for the development of software for programmable electronic systems for use in railway control and protection applications. It is aimed at use in any area where there are safety implications. These systems can be implemented using dedicated microprocessors, programmable logic controllers, multiprocessor distributed systems, larger scale central processor systems or other architectures. The main technical changes with respect to the previous edition are as follows:
- addition of requirements on software management and organisation, of definition of roles and competencies, deployment and maintenance;
- addition of a new subclause on tools based on IEC 61508-2:2010.
