Introduction, application, benefits

Machine and plant constructors are being increasingly requested to offer more flexible and productive machines at reduced prices. This places new demands on the automation systems with respect to e.g. scope of functions, processing speedand size, as well as engineering and networking. PLCs are required with a large scope of functions and high processing speeds in a compact design. The networking facilities should be improved at the same time, but the engineering requirements should be simultaneously reduced. SIMATIC S7-300 is the most widely sold PLC within the context of Totally Integrated Automation with many successfulreference applications worldwide found in many different industrial sectors. S7-300 users profit from the experience and global servicing facilities of the market leader as well as the quality associated with SIMATIC. This is the basis for increasing profits and improving competitiveness using innovative automation solutions. The S7-300 has been designed for innovative systems solutions with theemphasis on production engineering, and is a universal automation platform providing optimum solutions for applications with central or distributed designs. Permanent innovations upgrade this automation platform even further. Examples include the powerful CPU modules whose range now also includes CPUs with integral Ethernet/PROFINET interface. Integral technological functions and integral safetyengineering mean that it is unnecessary to invest in additional devices. Application The SIMATIC S7-300 offers solutions for the most diverse automation tasks in the following areas: • Production engineering • Automotive industry • General machine construction • Specialized machine construction • Machine construction in series, OEM 2

Production line in the automobile industry – automated with theS7-300

• Plastics processing • Packaging industry • Food and drink industry • Process engineering Special applications For special applications there are additional product designs available based on S7-300: · Fail-safe applications: S7-300F and matching I/O1) · For applications requiring powerful technological and motion control functions: Technology CPU 317T-2 DP 1) · Machine control in compactform: SIMATIC C7 all-in-one control systems with integral HMI on basis of the S7-300 CPUs 1) • Distributed, intelligent preprocessing: CPU in ET 200S and ET 200X design 1) Low engineering costs The S7-300 is characterized by efficient configuring and programming which results in low engineering costs. The huge quantity frameworks of the CPUs make the S7-300 an ideal platform for the task-orientedSTEP 7 Engineering Tools complying to IEC 61131-3, for example high-level languages such as SCL. In addition, technology-oriented runtime software, e.g. Easy Motion Control can be used for motion control tasks.

The Engineering Tools also facilitate modular programming and re-usability of existing software. Engineering Tools not only support development but also readability, ease of maintenanceand documentation of programs. High availability Additionally, powerful integral system diagnostics increase controller availability and thus productivity. Configurable process diagnostics for analyzing process faults, reducing downtimes and further enhancing of productivity are also implemented. Low operating costs The Micro Memory Card can act as data and program memory so that no backup batteryis required and maintenance costs can partly be saved. The Micro Memory Card can also accommodate a complete project, including symbols and comments, which makes servicing easier since no project data are required on the respective device. The Micro Memory Card also facilitates program updating. It permits read and write access during RUN so that, for instance, archiving of measured values or...
