configuration for software redundancy URGENT!

anony Posts: 23 Rating: (0)	Hi All , I am having an S7 400R system which is working perfectly at the PLC end with respect to the switch over. I want to know what configuration should be done in WinCC flexible with respect to the connection/changeover etc to enable the switch over in the Operator panel. I am using an MP 277 10" Touch panel and I want the switch over to happen on the same in case one CPU fails. i.e If CPUA fails, the OP should consider CPUB as master and vice versa. If there is any usefull link on how to do this switchover configuration on WinCC flexible , it would be really usefull. Thanks in advace

anony Posts: 23 Rating: (0)	Hi , I have tried this way also as per the manual, But I dont think this method of configuration on WinCC Flexible can be used in case of software redundancy . I am using two 414-2 CPU's which are software redundant and connected to the MP277 via MPI . I only want the HMI to switch over in case of CPU failure. Thanks in advance
