Project Window
The project window is split into two halves. The left half shows the tree structure of the project. The
right half shows the objects that are contained in the object open in the left half in the selected view
(large symbols, small symbols, list, or details).
Click in the left half of the window on the box containing a plus sign to display the full tree structure
of the project. The resulting structure will look something like the following figure.
At the top of the object hierarchy is the object "S7_Pro1" as the icon for the whole project. It can be
used to display the project properties and serves as a folder for networks (for configuring
networks), stations (for configuring the hardware), and for S7 or M7 programs (for creating
software). The objects in the project are displayed in the right half of the project window when you
select the project icon. The objects at the top of this type of object hierarchy (libraries as well as
projects) form the starting point in dialog boxes used to select objects.
Project View
You can display the project structure for the data available on the programming device in the
component view "offline" and for the data available on the programmable control system in the
component view "online" in project windows.
An additional view you can set is available if the respective optional package is installed: the plant
view.
Note
Configuring hardware and networks can only be done in the "offline" view.
