Installing and Starting the Ethernet CP with STEP 7

2.4Downloading the Configuration Data to the Target System

Principle

The configuration data of the Ethernet CP are downloaded from the hardware configuration. All the configuration data of the S7 station are downloaded including the central configuration, all relevant DP master systems and all parameter settings.

The data of the configured connections must also be downloaded, see below.

Type of Interface

You can download the configuration data to the S7 station on the following paths (interfaces):

SMPI interface

You can use this interface to download configuration data or when assigning a MAC/IP address for the first time (node initialization – for details, refer to the manual /1/ “Assigning Addresses for the First Time”).

SIndustrial Ethernet

Here, you use the PG mode of the Ethernet CP in the S7 station (see also Section 1.3).

Depending on the PG/PC interface used by the station on which you create your configuration, you can download the defined configuration data to the S7 station over the TCP/IP interface or over the ISO interface of STEP 7.

When you download over the IP interface, the CP must already have been assigned an IP address; refer to Chapter 2.3.

When you download over the ISO interface, you can use the preset MAC address. However, please note the following:

Note

If you want to download the configuration data over the ISO interface to a CP with an unchanged, factory-set MAC address and you have configured a different MAC address in your STEP 7 project, you must start the download in NetPro or HW Config; this is the only way you will be prompted to enter the current MAC address. The SIMATIC Manager, on the other hand, aborts the download if the target station cannot be reached.

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.
