Cause

Several interconnected bus ports are combined into a physical network. In the concrete case one or multiple bus ports connected to each other that are part of a physical network have different values assigned for the property Physical network: Name. The different values are output in the placeholders <x> and <y> of the message.

Solution

1. Use the Go to (graphic) and Go to (2nd coordinate) functionalities, which are available in the popup menu of the Message management dialog, to navigate to the network / bus cable connection points of the physical network that are connected to each other.
2. Call up the respective property dialog at the network / bus cable connection points and enter the same value in the Bus port tab in the Physical network: Name field. Or alternatively, enter the name of the physical network only at one of the network / bus cable connection points that are connected with each other and delete it at the other network / bus cable connection points.
3. Update the connections.
4. If required, start a new check run.
