自动化领域中使用103协议的保护测控装置非常多，但是maxDNA分散控制系统的通信模块不支持103协议。介绍了基于maxDNA系统SBP技术的南自以太网103主站协议的设计，重点讲述了103主站的几种冗余模式设计，分析了各自的优缺点，并测试了双主站双网冗余模式的性能。基于maxDNA系统的以太网103主站，与从站采用UDP报文与TCP报文相结合的方式通信，提高了信息传输的及时性，保证了数据的完整性和正确性，多种冗余方式的支持，可根据现场应用的具体需求选择适用的冗余模式，增加了系统的安全可靠性和灵活性。

To seamlessly accommodate various kind of electrical automation equipments into the maxDNA DCS system so as to create an unified and integrated solution for power plant automation,a back-end server that conforms to SAC103 (an enhanced version of lEC870-5-103) protocol is presented.Enhanced with a set of novel active/standby switch-over mechanisms,which are tunable as according to specific project requirements,the communication server may operate with a warm backup con-figured in the run-time.Through automatical y switching the transport between TCP and UDP.
