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.

Configuring General parameters
You specify the communication parameters in the "Properties" configuration dialog of the
communication instruction. This dialog appears near the bottom of the page whenever you
have selected any part of the instruction.
Refer to "Device configuration: Configuring the Local/Partner connection path (Page 118)"
for more information.
In the "Address Details" section of the Connection parameters dialog, you define the TSAPs
or ports to be used. The TSAP or port of a connection in the CPU is entered in the "Local
TSAP" field. The TSAP or port assigned for the connection in your partner CPU is entered
under the "Partner TSAP" field.
