Installing and Starting the Ethernet CP with STEP 7

Procedure

To download the configuration data to the S7 station, follow the steps outlined below:

 

1.

Open the “Set PG/PC Interface” dialog box in the Windows Control Panel.

 

2.

Set the PG/PC interface according to the CPs available on your PG and

 

 

according to the bus attachment (interface parameter assignment used).

For more detailed information, refer to the integrated help system.

3.

Change the CPU to the STOP mode (regardless of the type of interface – see

 

 

 

above).

 

4.

Select the menu command PLC " Download to Module.

STEP 7 then guides you through dialog boxes. Note the additional information in the “STEP 7 User Manual”, Chapter “Configuring and Assigning Parameters to Modules” /6/.

Deactivating the MAC Address in the Configuration

If you deactivate the use of the MAC address when you are configuring the CP, the CP can be reached via the preset MAC address, however you cannot define any ISO transport connections or S7 connections over ISO connections in your configuration.

Saving the Configuration Data in Non-Volatile Memory

You can download the configuration data step-by-step or all at once. If you download step-by-step, you will be prompted to start the download function separately for each module. You must select this method if you want to save the configuration data in non-volatile memory on the Ethernet CP. In this case, select the “Copy to ROM” button in the “Download” dialog for the CP.

Downloading the Configured Connections

To download configured connections, you use a corresponding download function in the connection configuration (NetPro).

Notice

If you have assigned a new address to the Ethernet CP or have configured connections, you must always download the connection configuration again.

Remember that you also make suitable address adaptations for the other stations or “substitute objects”.

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.
