          1.冗余系統(tǒng)


          所謂冗余系統(tǒng)是指系統(tǒng)中有多余的部分,沒有它系統(tǒng)照樣工作,但在系統(tǒng)出現(xiàn)故障時,這多余的部分能立即替代故障部分而使系統(tǒng)繼續(xù)正常運行。冗余系統(tǒng)一般是在控制系統(tǒng)中最重要的部分(如CPU模塊)由兩套相同的硬件組成,當某一套出現(xiàn)故障立即由另一套來控制。是否使用兩套相同的I/O模塊,取決于系統(tǒng)對可靠性的要求程度。


          兩套CPU模塊使用相同的程序并行工作,其中一套為主CPU模塊,一塊為備用CPU模塊。在系統(tǒng)正常運行時,備用CPU模塊的輸出被禁止,由主CPU模塊來控制系統(tǒng)的工作。同時,主CPU模塊還不斷通過冗余處理單元(RPU)同步地對備用CPU模塊的I/O映像寄存器和其它寄存器進行刷新。當主CPU模塊發(fā)出故障信息后,RPU在1~3個掃描周期內將控制功能切換到備用CPU。I/O系統(tǒng)的切換也是由RPU來完成。


          a)冗余系統(tǒng)b)熱備用系統(tǒng)


          2.熱備用系統(tǒng)


          熱備用系統(tǒng)的結構較冗余系統(tǒng)簡單,雖然也有兩個CPU模塊在同時運行一個程序,但沒有冗余處理單元RPU。系統(tǒng)兩個CPU模塊的切換,是由主CPU模塊通過通信口與備用CPU模塊進行通信來完成的。兩套CPU通過通訊接口連在一起。當系統(tǒng)出現(xiàn)故障時,由主CPU通知備用CPU,并實現(xiàn)切換,其切換過程一般較慢。
