S7 Redconnect

dear all.
I use S7 400H CPU 414H with one CP443-1 with one CPU 414H, Two CP443-1 use one Industry Ethernet connect with PC run WinCC over one CP1613 card. But, when main CPU 414H die, WinCC can connect with Redundant CPU 414H over CP443-1?, because MAC address of CP443-1 main and MAC address of CP443-1 redundant, do i need to use S7 redconnect in this case?.
Help me.

You always need redconnect when u are comunicating with an H system

Under Dynamic Wizard of WinCC there is inbuilt script "Create redundant Connection" under system function tab.

Only thing to be done is that click on any picture and then doubal click on this script.
This script will ask you the IP address of the SLAVE CPU and RACK number of it, provide both this information and you are done.
Now whenever the MASTER CPU goes OFF the WInCC will continue to show you all the data via SLAVE CPU.
No redconnect is required.
