سوالی از همکاران محترم داشتم

آیا میشه ورژن CPU های S7-400H را بدون اینکه فرآیند دچار توقف بشه تغییر داد؟

سلام

بله اگر ورژن CPU V4.0 و یا بالاتر باشد امکان پذبر است .

ابتدا Standby CPU را انتخاب کنید و آن را در مد Stop قرار دهید و Firmware آنرا آپدیت کنید سپس از Switch to گزینه with altered operating system
را انتخاب کنید و عملیات را برای CPU دوم تکرار کنید.

پس از Restart CPU در مد Redundant قرار می گیرد . (برای کارت حافظه RAM )

فکر کنم روشی که مهندس رهایی گفتن فقط برای upgrade بدون توقف امکان پذیر باشه

برای downgrade نمیشه چون اجازه switch to نمیده

مهندس از سوال ایشان به نظر می رسد که هر دو CPU در حال کار است و منظورشان از تغییر، Update Firmware است و در این حالت روشی که از Stop پلنت جلوگیری کند روشی بود مطابق منوال زیمنس بیان شد

اگر CPU جدیدی تهیه شده که ورژن آن بالاتر از CPU در حال کار است و میبایست ورژن آن Down شود، باید به صورت مستقل ورژن CPU جدید به ورژن CPU در حال کار تغییر کند و سپس در رک H قرار گیرد تا مد Redundant فعال شود و در این حلت هم نیازی به Switch to نمی باشد.
