Creating an S7 connection

The connection type that you select creates a communication connection to a partner
station. The connection is set up, established, and automatically monitored.
In the Devices and Networks portal, use the "Network view" to create the network
connections between the devices in your project. First, click the "Connections" tab, and then
select the connection type with the dropdown, just to the right (for example, an S7
connection). Click the green (PROFINET) box on the first device, and drag a line to the
PROFINET box on the second device. Release the mouse button and your PROFINET
connection is joined.
Refer to "Creating a network connection" (Page 117) for more information.
Click the "Highlighted: Connection" button to access the "Properties" configuration dialog of
the communication instruction.
