Can Client and Runtime Runs together?

Can Client and Runtime Runs together?


I would like to know below design is proper with zenon 11 EE edt.

I want usual server-client redundant design with 2 servers and 6 client.But if both servers fails , the client PCs should still communicate with PLCs.

1)Is it possible to make this kinda work without creating independent project which will be a standalone project inside of client PCs ?

2)If I managed created a new program and switch to it when servers fails,how can I match historian data after everything normalized ?

Thank you for answers already,
