Hello everyone.I got a new IM153-2AA02-0XB0 and I saw  LED's  BF1 and BF2
on the front of board IM153-2.

My previous module IM153-2 has BF LED .

BestRegards and thanks.. 

Hello,

and what do you want to know from us?

If you want to know sth about LEDs, you can look in the manual of the module

Hello sara.rez;

The manual Pittisplash has mentionned can be found here:

SIMATIC Distributed I/O device ET 200M

Basically, a BF (Bus Fault) LED indication means that the Profibus configuration on the IM 153-2 is not correct.

What master is the IM 153-2 connected to (the master should also have a BF LED active)? What Profibus address has been set on the dipswitches of the IM 153-2 and does that address match the one used in the master's Profibus configuration? What modules are installed on the IM 153-2 rack and are any of them faulty?

If you are connected to the DP-master with step 7 you can study the messages in the diagnostic buffer to find out what the BF LEDs correspond to.

Hope this helps,

Daniel Chartier

Hello

Regarding the LEDs, the module should be 6ES7 153-2BA02-0XB0, not 6ES7 153-2AA02-0XB0.

Does the 6ES7 153-2BA02-0XB0 replace the 6ES7 153-2AA02-0XB0 ?

Can the 6ES7 153-2BA02-0XB0, module be used in S7 V5.2?

Best Regards
