摘　　要：冗余功能是一个工业控制网络系统成功的关键环节,是保证系统稳定、安全、可靠的重要手段。文章在西门子S7-300软冗余系统工作原理的基础上,提出了软冗余系统的硬件组成及程序实现方法,通过电源模块、CPU、冗余模块、通信模块以及I/O等相关硬件,完成相应的软件组态。It is pointed out the redundancy function is a key link to succeed of control network system in industry. It is important means to ensure system stable,system safe and system reliable. Based on the Siemens S7 - 300 software redundancy principle, this paper proposed soft-redundant hardware components and programming methods. By configuring the power modules, CPU, redundant modules, communication modules and I/O modules and related hardware, accurate and complete the software configuration.
