Hello, in your case a second HMI Connection is not need, you can use the _1 Connection.

Thanks ChristophD, And that brings me back to the topology view - see attached screenshots. Why can the setup with an "extra connection" work in one case and not in the (almost identical) other case ? I believe the second connection was made for a reason (cannot remember the reason) and would prefer to keep it - are you smart people SURE it serves no purpose ? Regards xmnj

Hi again, My problem is that I the (simulation of) the HMI panel cannot "find" my signals - see attached screenshots. I had problems getting the project downloaded to a controller - difficulties with IP A - but somehow the IP A was set correctly - see this thread;IP address thread I experienced this before and you helped me solve it is this thread: unresolved objects thread.

Hi again, I am still too new and inexperienced - so I am not sure what screen you mean ? See also attached screenshots. I do not have a BOP for the controller and not yet access the the physical HMI panel. So that is simulated as we talked about. Is the PG/PC device not the same for S7 and WinCC when they are both the same TIA version - and I CAN change thing in the PLC -so I should be in contact with HMI panel too - right? I unfortunately do not know where to check those settings "the HMI Connection properties that s7Online is configured and the Partner station have the IP of you PLC" But the only screen I have for the HMI panel just now is the one that TIA produces when I start the simulation. That CAN work - I have seen it work with two very similar systems. In the project the IP A's of the PLC and panel are set correctly. In the physical PLC it is set correctly.
