4.3.1 Creating a New Connection
Principle
When you create new connections, you start from entered and networked stations.
A connection is then configured starting from a station or CPU in the current S7
project and then selecting a destination station.
Due to the networking, the node addresses (MAC or IP addresses) of the two
stations are already decided. The local/remote TSAPs (Transport Service Access
Point) or ports at both ends of the connection are automatically assigned default
values.
If the partner station is a station outside the current project or a non-S7 station, the
remote TSAPs (Transport Service Access Point) or ports must be specified in the
Properties dialog of the connection.
The endpoint of the connection to a SIMATIC S7 station is always a CPU. A
separate connection table is created for each CPU and displays the connection
partner and types of connections.
New Connection
To configure a new connection, the stations and their CPs must be configured and
networked in the S7 project. To create a new connection, follow the steps below:
In NetPro, follow the steps below:
1. In NetPro, select the station or the CPU in the station from which you want to
establish the connection.
2. Select the menu command Insert " New Connections (also available with the
right mouse button!).
Result: The following dialog appears on the screen.
