5.3.1 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.
Creating a 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.
