Procedure
Configuring Connections
A connection defines the communication relationship between two nodes. It
defines the following:
• The two communication nodes involved
• The connection type (for example, S7, point-to-point, FMS, ISO-on-TCP, FDL,
or ISO Transport)
• Special properties which depend on the type of connection (such as whether a
connection remains permanently configured, or whether it is set up/broken
dynamically in the user program)
You must be in the network view of NetPro.
1. In the network view, select the module for which you want to create a
connection.
Result: The connection table for the selected module is displayed in the lower
half of the network view.
2. Double-click an empty row in the connection table, or select a row and select
the menu command Insert > Connection.
3. In the "New Connection" dialog box select the required connection partner.
You can obtain help with selecting a connection partner in the online help for
this dialog box.
4. Specify the type of connection.
5. 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:"
The contents of the "Properties" dialog box is dependent on the connection
selected; you can obtain help with filling it out in the online help for the dialog
box.
Result: STEP 7 enters the connection in the connection table of the local
(selected) node and assigns the local ID and a partner ID if required for this
connection which you will need when programming the communication function
blocks (value for the block parameter "ID").
