SIEMENS S7-300

SIMATIC S7-300

Siemens PLC
The modular controllers for innovative system solutions in the manufacturing industry 
The SIMATIC S7-300 has been designed for innovative system solutions with the focus on manufacturing engineering, and as a universal automation system, it represents an optimal solution for applications in centralized and distributed configurations: 
The product range comprises 7 Standard CPUs, 6 Compact CPUs, 6 failsafe CPUs and 2 Technology Siemens PLC CPUs. 

Highlights
The ability to integrate powerful CPUs with Industrial Ethernet/PROFINET interface, integrated technological functions, or fail-safe designs make additional investments unnecessary.  
The S7-300 can be set up in a modular configuration without the need for slot rules for I/O modules. There is a wide range of modules available both for the centralized and the distributed configuration with ET 200M.  
The Micro Memory Card as a data and program memory makes a backup battery superfluous, and with it, part of the maintenance costs. In addition, an associated project, including symbols and comments, can be stored on this memory card to facilitate service calls.  
The Micro Memory Card also enables simple program or firmware updates. The Micro Memory Card can be used during operation for storing and accessing data, e.g. for measured value archiving or recipe processing.  
In addition to standard automation, safety technology and motion control can also be integrated in an S7-300.  
Many of the S7-300 components are also available in a SIPLUS version for external environmental conditions, e.g. extended temperature range (-25...+60 °C) and for use where there is aggressive atmosphere/condensation.

Digital modules

Description

Digital actuators and sensors can be connected to a SIMATIC S7-300 via digital modules. The extensive range of modules allows the most suitable signal module to be selected in each case.

Analog modules

Description

More complex tasks require the processing of analog process signals. Analog actuators and sensors can be connected to a SIMATIC S7-300 via analog modules without additional amplifiers. The extensive range of modules allows the most suitable signal module to be selected in each case.
