Problem Solved!
I first, set the node address of HMI in transfer settings to 15, then removed the HMI object from Profibus line on HWconfig,and set the WinCC address to 15 and then checked the "Only Master on the Bus" option.
I downloaded the hwconfig and everything became OK! No BF and no SF flashing anymore!
Thanks for answers!
