Available in PDF, EPUB and Kindle. Book excerpt: PROFINET is the first integrated Industrial Ethernet Standard for automation, and utilizes the advantages of Ethernet and TCP/IP for open communication from the corporate management level to the process itself. PROFINET CBA divides distributed, complex applications into autonomous units of manageable size. Existing fieldbuses such as PROFIBUS and AS-Interface can be integrated using so-called proxies. This permits separate and cross-vendor development, testing and commissioning of individual plant sections prior to the integration of the solution as a whole. PROFINET IO, with its particularly fast real-time communication, fulfills all demands currently placed on the transmission of process data and enables easy integration of existing fieldbus systems. Isochronous real-time (IRT) is used for isochronous communication in motion control applications. PROFINET depends on established IT standards for network management and teleservice. Particulary to automation control engineering it offers a special security concept. Special industrial network technology consisting of active network components, cables and connection systems, together with recommendations for installation, complete the concept. This book serves as an introduction to PROFINET technology. Configuring engineers, commissioning engineers and technicians are given an overview of the concept and the fundamentals they need to solve PROFINET-based automation tasks. Technical relationships and practical applications are described using SIMATIC products as example.

Download or read book A Comprehensible Guide to Servo Motor Sizing written by Wilfried Voss and published by Copperhill Media. This book was released on 2007-08 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Importance of servo motor sizing should not be underestimated. Proper motor sizing will not only result in significant cost savings by saving energy, reducing purchasing and operating costs, reducing downtime, etc.; it also helps the engineer to design better motion control systems. However, the knowledge of mechanical systems and their influence on motor speed, inertia and torque requirements seems to decline in a world where modern technology aspects, such as tuning and programming, seem to be the main focus. The motor sizing process involves a number of mathematical equations, which are most certainly documented, but not necessarily with the motor sizing process in mind. This book focuses primarily on servo motor sizing and it documents in detail the inertia and torque calculations of standard mechanical components and the motor selection process.
