OB 57 Failure

Hello ,

I have an OB 57 not  loaded Failre , before the system based on S7-410 5H work normaly

thx

Hi Kour!

The OB57 function is  manufacturer specific interrupt ,so you should call the manufacture of the machine to get the advice what you should to do 

Thank you  MAZENJER,

I checked my Profibus networks , I keep just the ready slave , without any disconnected slave , so without Bus Fault , this message error does not appear any more .
