佳答案
在診斷信息描述中調(diào)用了OB80。
OB80 :時間故障。可能的原因:
這樣的故障包括: 循環(huán)時間超出、執(zhí)行OB 時應(yīng)答故障、向前移動時間以致于躍過了OB 的啟動時間、CiR 后恢復(fù)RUN 方式。如果,例如,當(dāng)循環(huán)中斷OB 仍在執(zhí)行前一次調(diào)用時,該OB 塊的啟動事件發(fā)生,操作系統(tǒng)調(diào)用OB80。如果OB80 未編程,CPU 變?yōu)镾TOP 方式。您可以使用SFC39 至42 封鎖或延時和再使能時間故障OB。
注意:如果在同一個掃描周期中由于掃描時間超出OB80 被調(diào)用兩次,CPU 就變?yōu)镾TOP 方式。您可以通過在程序中適當(dāng)?shù)奈恢谜{(diào)用SFC43“RE_TRIGR ”來避免這種情況。
