4. The components are wired either from the selected structure node of the tree view or directly
from the wiring diagram via the "Connect component" context menu entry.
The components that can be used at this point of the topology can be selected from the
module catalog and inserted and wired in the list of the used components. In this way, it is
ensured that a valid topology is created and that components are not connected twice.
Alternatively, you can drag and drop the components from the module catalog to the
"topology configurator" and connect them (save).
