Configuring Communication Connections

4.3.1Creating 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.

S7 specifications

The Siemens S7 series represents a cornerstone in the realm of programmable logic controllers (PLCs), developed by Siemens, a leading company in industrial automation. Widely used across various industries, the S7 series offers robust solutions for controlling machinery and processes, thanks to its reliable performance, flexibility, and scalable architecture.

One of the key features of Siemens S7 PLCs is the modularity of their design. Each system can be configured to meet specific application requirements due to the ability to mix various input/output modules, CPUs, and communication processors. This modular approach allows for the customization of systems to suit diverse automation tasks, providing end users with the adaptability required for modern manufacturing environments.

The S7 series encompasses several models, including the S7-1200, S7-300, and S7-1500. The S7-1200 is particularly suited for small to medium-sized applications, offering a compact design and integrated communication interfaces. In contrast, the S7-300 is designed for more extensive and complex control systems, making it ideal for large-scale industrial applications. The S7-1500 stands out with its advanced performance metrics, rich feature set, and high-speed processing capabilities, making it perfect for demanding applications that require real-time control and extensive data handling.

Siemens also emphasizes the importance of communication technologies within the S7 series. With options such as PROFINET, PROFIBUS, and EtherNet/IP, the S7 PLCs can seamlessly integrate into existing automation infrastructures, ensuring smooth data exchange between devices. The incorporation of web-based technologies and cloud connectivity further enables remote monitoring and control of systems, enhancing operational efficiency.

Another notable characteristic of Siemens S7 PLCs is the use of TIA Portal (Totally Integrated Automation Portal), an innovative software platform that simplifies the engineering process. TIA Portal allows users to program, configure, and diagnose their automation devices in a single environment, reducing setup times and improving productivity.

In conclusion, the Siemens S7 series stands out due to its modular design, range of models suitable for various applications, advanced communication technologies, and user-friendly programming software. This combination of features and characteristics makes S7 PLCs a preferred choice for industries seeking reliable and efficient automation solutions. As industrial demands continue to evolve, Siemens S7 PLCs remain at the forefront, adapting to technological advancements and setting benchmarks in the automation field.
