11.6.2 Creating and Assigning Parameters to a New Subnet
Requirement
Procedure
Tips:
NetPro must be open.
Note
STEP 7 automatically and centrally sets consistent subnet properties (e.g.
transmission rate) for all nodes in a given subnet.
If you set or modify subnet properties in STEP 7, you must make sure that each
node in the system subnet adopts these settings (Downloading a Configuration to a
Programmable Controller ).
1. If the "Catalog" window is not visible:
Open the "Catalog" window using the menu command View > Catalog.
2. Click on "Subnets" in the "Catalog" window.
3. Click on the required subnet, hold the mouse button pressed, and use the drag
& drop function to copy the subnet to the window for the graphic network view.
Invalid positions for subnets in the view window are shown by a sign instead
of the cursor.
Result: The subnet appears as a horizontal line.
4. Double-click the symbol for the subnet.
Result: The properties dialog box for the subnet is displayed.
5. Assign parameters to the subnet.
You can open an information window giving details about the subnet properties by
holding the mouse on the symbol for the subnet.
