Hello, I have the same issue. I'm working with WinCC 7.4 SP1 Update 6. I have also a dedicated network adapter used for the redundancy. Redundancy between two servers, alarm and tag logging synchronization, are working but internal tags with "Synchronization" check won't work. ------------------------------------------------------------------------------------------ |

Thanks for the fast reply. At the end I've found that issue was caused by wrong time synchronization from master and standby. |
