Networking Stations
Procedure
1. If the "Catalog" window is not visible:
Open the "Catalog" window using the menu command View > Catalog.
2. In the "Catalog" window click on the required object (under "Stations"), hold the
mouse button pressed, and use the drag & drop function to copy it to the
window for the graphic network view.
Invalid positions in the view window are shown by a sign instead of the
cursor.
Alternatively you can also double-click the required object in the "Catalog"
window.
3. Double-click the object.
Result: A dialog box with tabs for setting the properties is displayed.
4. Set the properties:
- For all objects except SIMATIC PC stations: in the "Interfaces" tab, create
the type of interface that the real object has (for example, PROFIBUS). Via
the "Properties" button, set the node and subnet properties.
Result: The object receives an interface symbol for every newly created
interface.
- For the "PG/PC" object: In the "Assignment" tab, set an assignment to an
existing module parameter assignment (PC card) if necessary. With this
assignment you link the "PG/PC" object in the network view with the actual
module parameters of your PG/PC. Advantage: If you, for example,
change the transmission rate of the subnet, the module parameters for
your PG/PC card change automatically.
