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.……
This section provides instructions on basic features and functions of
the 475 Field Communicator. It also provides information on assembly,
components, starting, entering standby, shutting down, settings,
applications, and maintaining the 475 Field Communicator. The
functionality described in this section is based on system software
A graded CPU range with a wide performance range is available for configuring the controller. The product range comprises 7 standard CPUs, 7 compact CPUs, 5 fail-safe CPUs and 3 technology CPUs. The CPUs are available from a width of only 40 mm
SIMATIC S7-300 is within Totally Integrated Automation the most sold Controller.
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 theSIPLUS extreme devices
Particularly in the finishing technique the S7-300 is used in the following industries:
General mechanical engineering
Building of special machines
Series mechanical engineering, OEM
Food and Beverage industry
Fast counting/fairs with direct access on the hardware counters
Simply positioning with direct control the MICROMASTER frequency static frequency changers
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 centra lexpansions or the construction of distributed structures with ET 200M; thereby producing very cost-effective spare parts handling.
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 centralrack and up to 8 per expansion unit. Interface modules(IMs) handle communication between the individual racksautonomously. In the case of plants covering wide areas, CCs/EUs can also be installed at greater distances from eachother (up to 10 m).
In a single-tiered configuration, this results in a maximumconfiguration of 256 I/O, and in multi-tiered configurations upto 1024 I/O. In distributed configurations with PROFIBUS DP,65536 I/O connections are possible (up to 125 stations, suchas ET 200M via IM 153). The slots are freely addressable, thatis, there are no slot rules.
The extensive range of S7-300 modules is also used in distributedautomation solutions. The ET 200M I/O system that hasthe same construction as the S7-300 can be connected via Interface modules not only to PROFIBUS but also to PROFINET.
