同步鏈路冗余
軟冗余 CPU 間的鏈路可以有三種選擇:CPU集成 MPI 接口、PROFIBUS-DP通信模塊和以太網(wǎng)通信模塊。因?yàn)閮蓚€(gè) CPU 之間只有一條數(shù)據(jù)鏈路,所以一旦這條同步鏈路發(fā)生中斷,會(huì)造成兩個(gè) CPU 無法同步。
在 S7-1500R/H 冗余系統(tǒng)中,兩個(gè) S7-1500R CPU 之間同步數(shù)據(jù)使用的是 PROFINET 環(huán)網(wǎng),即使 CPU 之間的連接網(wǎng)線斷開,但由于是環(huán)網(wǎng)形式,同步數(shù)據(jù)還是可以從另外一側(cè)的網(wǎng)絡(luò)進(jìn)行。而 S7-1500H CPU 是有兩根光纖專門用于同步,本身就是冗余設(shè)計(jì),即使一根斷開也不影響兩個(gè) H CPU 之間的同步。
