灼華樂(lè)享PILZ安全模塊PNOZ S5? ?751105?
首先,我們要明白故障安全模塊的鈍化是一種保護(hù)機(jī)制。除了系統(tǒng)剛上電啟動(dòng)外,鈍化通常因?yàn)楣收习踩K檢測(cè)到了某種故障而觸發(fā)。這種故障可能是故障安全模塊與故障安全CPU之間的PROFIsafe通信故障,也可能是故障模塊本身檢測(cè)到了錯(cuò)誤。比如,對(duì)于1oo2 對(duì)等的傳感器評(píng)估,檢測(cè)到同組的兩個(gè)通道信號(hào)不同;或者對(duì)于1oo2不對(duì)等的傳感器評(píng)估,檢測(cè)到同組的兩個(gè)通道信號(hào)相同。無(wú)論是哪種故障,都會(huì)引發(fā)模塊鈍化。? 鈍化的具體表現(xiàn)是:用安全值替代正常值,這里的安全值通常是"0"。對(duì)于F-DI輸入信號(hào)而言,會(huì)用"0"取代通道的輸入信號(hào);對(duì)于F-DQ輸出信號(hào)而言,會(huì)將輸出值賦"0",而忽略故障安全程序的計(jì)算結(jié)果。? 有了上面的知識(shí),對(duì)于留言的問(wèn)題就比較好回答了。? 假設(shè)故障安全輸入模塊采用了1oo2對(duì)等的傳感器評(píng)估方式,急停按鈕連接到某雙通道組內(nèi)。一般情況下,這兩個(gè)通道的信號(hào)是同時(shí)變化的,即同時(shí)接通或斷開,這種情況下是不會(huì)引發(fā)模塊鈍化的。除非急停按鈕的雙通道不能同時(shí)動(dòng)作,這種情況極少。? 急停按鈕接線完成后,還需要在故障安全程序中編寫相應(yīng)的代碼才能達(dá)到較高的安全等級(jí)。你可以參考下我的文章:西門子PLC故障安全編程——ESTOP1指令? 每一個(gè)故障安全模塊都有一個(gè)數(shù)據(jù)塊(F-IO DB)存放該模塊的一些參數(shù)。當(dāng)模塊發(fā)生鈍化后,其F-IO DB的PASS_OUT和QBAD會(huì)變?yōu)門RUE。這種情況下要先消除故障原因,然后重新集成才能正常工作。
