Requirement

Configuring Connections
If you wish to reserve the communication resources of a node to expand your
project at a later date, or if you do not wish to specify a connection partner yet, you
can enter "Unspecified" for the connection partner. Reserving connections is
currently not possible for all connection types.
You must be in the network view of NetPro. The properties dialog box for the
connection is open.
1. In the "Station" box, select the option "Unspecified."
Result: The entry in the "Module" box is deactivated.
2. Select the connection type in the "Type" box.
3. Activate the "Show Properties dialog box" check box if you want to view or
change the properties for the connection after clicking "OK" or "Add."
4. Confirm your entries by clicking "OK."
Result: STEP 7 enters the connection in the connection table of the local node
and assigns the local ID for this connection which you will require for
programming the communication blocks.
Note that you can also assign special properties for each connection. To do this,
select the menu command Edit > Object Properties.
