Rudrani Posts: 163 Rating: (4)	hi all, I have a S7 300 and simotion D410 both are communicating on profibus network. I have defined I/O addresses in hardware. PLC is master and D410 is configured as slave. Communication has been esblished and its working fine. but there is SF on CPU. I have also attached a print screen of diagnostic buffer with this thread. SF is about I/O acess. So I downloaded the hardware again, but still there is an error. But my communication is working properly. Pls help...as soon as possible. regards, Rudrani Attachment diagnostic buffer.jpg (68 Downloads)
