با سلام و احترام

همانطور که مطلع هستید در wincc تگ ها با فاصله زمانی حداقل 500 ms زخیره و آرشیو گیری می شوند.

حال اگر بخواهیم تغیرات یک سیگنال آنالوگ حساس را در حدود هزارم میلی ثانیه هم ثبت بشه به چه سخت افزار یا نرم افزار نیاز داریم؟ با تشکر

برای ثبت سیگنال ها با Cycle time خیلی کم میشه از رکوردرهای خاص استفاده کرد

مثه SIREC زیمنس

میتوانید تنظیم نمونه برداری از تگ را به صورت Acyclice و Upon change در نظر بگیرید.

آیا نمونه های گرفته فقط به هنگام تغییر برای استفاده و تحلیل مناسب هستند؟

@sgh سلام، برنامه در ob35 و به صورت cycle نوشته شده(100ms) تنظیمات wincc هم همون upon change هست.

بله نمونه ولتاژ در همان لحظه خطا برای تحلیل نیاز می باشد.

لحظه خطا در حد هزارم میلی ثانیه است. میخوایم این افت ولتاژ در این تایم ببینیم که تا چه حد ولتاژ افت میکنه.

درود بر گرامیان

در S7-1200 , S7-1500 امکان Trace اضافه شده که میتونه یک سولوشن خوب برای نمونه برداری سریع باشه . زمان نمونه برداری میتونه خیلی کوتاه در حد میکروثانیه یا در حد سیکل اجرای OB1 باشه
