I'm especially interested in H series PLC and possible redundancy changeover time. Can you post link to the appropriate manual? Thank you very much

I am giving a link to 417-HCPU tech spec. https://mall.automation.siemens.com/DE/guest/index.asp?aktprim=0&lang=en&nodeID=10007552&foldersopen=-1385-1386-1387-1388-1591-1685-1686-1689-1688-&jumpto=1688
