Hello, did somebody try to increase the number of the priority? I have the same problem. I Will try to do that but isn't clear why happened like that. Also from the manual of Siemens have many reason and is really difficult to find the right solution. I'm so sad to say Siemens = STOP Production :-( ------------------------------------------------------------------------------------------ |

Are you having a PLC stop while a safety OB is running? If the OB (or block it calls) uses tags that get updated at the end of a normal PLC scan, you can block that by increasing the priority of the OB to 17 (highest), and at the start of the OB disable interrupts, and at the end of the OB, enable interrupts. That's a powerful combination that should only be used when you cannot find a better way around it.
