Installing and Starting the Ethernet CP with STEP 7

S Replace Module without PG

With this option, you can have the configuration data of the CP stored

 

on the CPU. If you then replace CP, the configuration data for the

 

new CP are downloaded automatically from the CPU when the CP is

 

started up.

 

If you select this option, the configuration data are stored long-term

 

on the CPU instead of in the EEPROM of the CP. Remember,

 

however, that long-term storage on the CPU is only safe from power

 

outages if the CPU is protected by battery backup or by using an S7

 

Memory Card.

 

Note

 

If you store the configuration data on the CPU, please read the note

 

below.

 

The following functions do not modify the configuration data on the

 

CPU:

 

S Resetting module memory

 

S Resetting to factory settings

 

S Assigning an IP address1) (using the target system selection in

 

the SIMATIC Manager or the properties dialog in HW Config or

 

NetPro)

 

If you subsequently upload the configuration data from the CPU to a

 

PG you will always object the configuration data that were previously

 

on the CP (with parameters, connections, IP address).

 

1) Note: You should only use the assign IP address function during

 

commissioning; in other words, before downloading the configuration

 

data.

 

 

S Ethernet Profile for

Select this profile if you use fault-tolerant communication in your

Fault-Tolerant Connections

system. Fault-tolerant communication means that Industrial Ethernet

 

is designed with redundancy and that you have configured

 

fault-tolerant S7 connections.

 

If you select the Ethernet profile for fault-tolerant connections here,

 

the time response of the S7 connections is adapted. As a result,

 

breakdowns of a connection are detected more quickly and the

 

failover to redundant connections is faster.

 

 

 

Note

 

Select the Ethernet profile for fault-tolerant connections only when

 

you actually use fault-tolerant S7 connections. Otherwise you must

 

expect your system to be more susceptible to problems since, for

 

example, the number of transfer or connection establishment

 

attempts is reduced compared with non-redundant systems.

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.
