با سلام و احترام

1-در کتاب آقای مهندس ماهر حالتی در بررسی خطای شبکه پروفی باس ذکر شده است(cross) که ارتباط پروفی باس بین master و et شماره یک قطع شود شبکه به کار خود ادامه می دهد در صورتی که فیبرنوری بین دو cpu قطع شود cpu رزرو در مدار نمی آید برای رفع این موضوع چگونه باید عمل کرد؟

2 در این سیستم S7400H که زیر دست(خروجی) Y کوپلر چندین et 200m قرار گرفته است به چه صورت در برنامه می توان مشخص کرد که کدام et شبکه پروفی باس اش قطع شده است؟ آیا با همان روش ob86 می توان اینکار را کرد؟

3- هر cpu را به چه روشی خطای شبکه اش را می توان تشخیص داد ؟

برنامه با s7 5.5 ساده می باشد و از pcs7 استفاده نشده است.

با تشکر
