Range of application

In the first instance SIMATIC S7-300 is used for innovative system solutions in manufacturing technology, especially for automobile industry, mechanical engineering in general and especially for special machine building and serial production of machines (OEM), at plastics processing, packaging industry, food and beverage industry and process engineering

As an all-purpose automation system is S7-300 the ideal solution for applications, which need a flexible concept for central as well as local configuration

For applications, which require a especial robustness because of surrounding conditions, we have the SIPLUS extreme devices

Particularly in the finishing technique the S7-300 is used in the following industries:

1. Automobile industry

2. General mechanical engineering
   

3. Building of special machines
   

4. Series mechanical engineering, OEM
   

5. Plastics processing
   

6. Packaging industry
   

7. Food and Beverage industry
   

8. Process engineering
   

9. Fast counting/fairs with direct access on the hardware counters
   

10. Simply positioning with direct control the MICROMASTER frequency static frequency changers
    

11. PID-Regulation with integrated functional module
    

Benefits

1. Thanks to their high processing speed, the CPUs enable short machine cycle times.

2. The S7-300's range of CPUs provides the right solution for every application, and customers only pay for the performance actually required for a specific task
   

3. The S7-300 can be set up in a modular configuration without the need for slot rules for I/O modules
   

4. There is a wide range of modules available both for the centralized and the distributed configuration with ET 200M.
   

5. Integral PROFINET interfaces enable simple networking of the controllers, and simple data exchange with the operations management level
   

6. The narrow module width results in a compact controller design or a small control cabinet.
   

7. The ability to integrate powerful CPUs with Industrial Ethernet/PROFINET interface, integrated technological functions, or fail-safe designs make additional investments unnecessary.

Siemens: SIMATIC Advanced Controllers (S7-300 Series)

Always the right Controller: for plant or mac

hine building, for production or process technology, for stand-alone or highly complex applications. Siemens offers the perfect control solution for every application - PLC or PC-based.
The range of SIMATIC Controllers starts from logic modules to Basic, Advanced and Distributed Controllers all the way to Software Controllers.

SIMATIC controllers from Siemens – The intelligent choice for your automation task

SIMATIC controllers from Siemens provide you with controllers for cost-effective automation solutions on all performance levels – with consistent functionality and standardized interfaces, perfectly optimized for applications with requirements ranging from simple to complex.

In addition to best performance, the new controller generation provides the advantage of scalability and functional consistency thanks to the uniform engineering in the TIA Portal and best-in-class solutions in terms of security and safety.

SIMATIC S7-300: the modular universal controller for the manufacturing industry

The SIMATIC S7-300 universal controller is specially designed for innovative system solutions in manufacturing, specifically the automotive and packaging industries.

This modular controller serves as an ideal universal automation system for centralized and decentralized configurations. Safety technology and motion control can be integrated with standard automation into this universal controller.

Powerful, compact and cost-effective

The SIMATIC S7-300 universal controller saves on installation space and features a modular design.

A wide range of modules can be used to expand the system centrally or to create decentralized structures according to the task at hand, and facilitates a cost-effective stock of spare parts. With its impressive array of innovations, the SIMATIC S7-300 universal controller is an integrated system that will save you additional investment and maintenance costs.

Design and function

Design

The S7-300 enables space-saving and modular configurations. In addition to the modules, only a DIN rail is required for hooking in the modules and screwing them into place.

This results in a rugged and EMC-compatible design.

The build-as-you-go backplane bus can be expanded by simply plugging in additional modules and bus connectors. The varied range of the S7-300 can also be used for central expansions or the construction of distributed structures with ET 200M; thereby producing very cost-effective spare parts handling.

Expansion options

If the automation task requires more than 8 modules, the central controller (CC) of the S7-300 can be expanded using expansion units (EUs) Up to 32 modules can be used in the central rack and up to 8 per expansion unit. Interface modules(IMs) handle communication between the individual racks autonomously. In the case of plants covering wide areas, CCs/EUs can also be installed at greater distances from each other (up to 10 m).

In a single-tiered configuration, this results in a maximum configuration of 256 I/O, and in multi-tiered configurations up to 1024 I/O. In distributed configurations with PROFIBUS DP,65536 I/O connections are possible (up to 125 stations, such as ET 200M via IM 153). The slots are freely addressable, that is, there are no slot rules.

The extensive range of S7-300 modules is also used in distributed automation solutions.

The ET 200M I/O system that has the same construction as the S7-300 can be connected via Interface modules not only to PROFIBUS but also to PROFINET.
