Go to devices & networks, activate connections and select HMI connection in drop down field. Then devices like PLCs and HMIs are highlighted. Add a connection by drag&drop between two devices. Then go back to connections view of the HMI and there should be a new connection with a different icon. Then you can remove the previous connection (with black cable icon). Regards, Frink
