摘要
应用414-5H冗余系统本身自带的PN接口,在不增加CP443的情况下实现与414-4H系统之间的无扰冗余切换。软件使用SIMATIC Step7 5.5,在netpro组态界面中的CPU下添加S7-connection链接,且使用西门子自带功能块SFD14(READ)和SFD15(WRITE)两个功能块,通过对其组态编程,实现两套冗余系统间数据的冗余交换。
The PN interface with 414-5 H redundant system is used to achieve non disturbance redundancy switching between 414-4 H system but without adding CP443. The software uses SIMATIC Step7 5.5 to add S7-connection links under CPU in the netpro configuration interface,and uses two functional blocks of SIEMENS＇s functional block SFD14（READ）and SFD15（WRITE）. By configuration programming,the data redundancy exchange between two sets of redundant systems is realized.
