با عرض سلام

در S7-300/400 آخرین OB شماره 122 بود و عملکردش هم برای I/O Access Error بود.

در S7-1500 شماره های بعدی هم وجود دارند مثه 123 و 124 که من کاربردشان را متوجه نشدم اگر ممکنه راهنمایی بفرمایید

ممنون

با درود و آرزوی تندرستی

بنظر می رسه OB های بالاتر از OB122 با شماره دلخواه در 1200 و 1500 می تونند بکار روند که عملکرد آن ها توسط برنامه نویس تعیین بشه. به عنوان نمونه مطابق عکسی که براتون ضمیمه کردم OB123 به عنوان Cyclic Interrupt در سیستم های Fail safe بکار رفته و حاوی لاجیک safety هست
