I use WINCC Flexible 2008 with 2 PLC CPU 315-DP in a software redundacy configuration. I can configure 2 Connection for 2 CPUs but my tag can address only one connection at a time. How is it possible to maintain the connection if other CPU becomes master. If all my tag address connection1 what happens when connection1 fails and connection2 takes over. how could i solve this problem
