Therefor i need a redundant connection swtiching between both CPU's if neccesary. For WinCC flex this was clear, scripts are known and working like in this example; Connecting a SIMATIC HMI operator device with a SIMATIC S7-1500R/H - ID: 109781687 - Industry Support Siemens But scripting is changed for Unified and i am not so good at scripting that i had succes with converting it.. Siemen support only handend me the "old" script so therefor i need help of all the smart programmers here. Does someone already have a redundant connection script running at unified? Thanks a lot!

Through the system IP the configuration is the same as in the application example. Through the script the configuration is also the same but the script changes. Here you can find a post with an example project adapted for WinCC Unified and some tips to create the script that may help you: "TIP: Connecting a SIMATIC HMI Unified with a SIMATIC S7-1500R/H" Even so, I'm going to look to see if I see more information about this script so I can help you. Best regards!
