Replace the module with a working module if every thing is checked and OK. I hope it helps, hdhosseini

When the BF-LED flashes, it means: IM 153-1 is incorrectly configured - no data exchange is taking place between the DP master and the IM 153-1. Causes: • Configured and set PROFIBUS address is incorrect • Faults on the bus or The configured structure of the ET 200M doesn´t tally with the actual structure of the ET 200M check the projected HW-config of the station and the DIP-Swiches for the PB-address. The IM153-2 needs a Powercycle after you changed the PB-address. Also check the Profibus at all. hope this helps, regards,
	FCK WAR! Be nice!

ganz11 Posts: 31 Rating: (0)	thank you so much everyone for your valuable replies... the problem was solved.. as per your advices, i have checked the resistors, i have replaced the ET200M module, configured the network and also downloaded a new program but the fault was same.. so i started replacing all the DI,DO,AI slaves in the rack and found that the digital output slave from the ET200M module was internally damaged, once i replaced the DO module, the fault disappeared.. i cross checked it again by swapping it with another DO of another slave and the fault shifted, so i confirmed that the fault is with the DO anyways thank you (hdhosseini, alex, scott and mopS04) for your support

So I shifted some modules to the another rack, now the same problem was repeating today. My module catalog no: 153-4BA00-0XB0

Open the hardware configuration / PN-IO section / right click and select Disconect PROFINET IO System and download the hardware again, the error status will be gone
