SERCOS III – uncompromising precision and efficiency

Because it delivers excellent performance in practical application, SERCOS has become the leading drive communication technology. High data transfer rates and high-precision synchronization make SERCOS III the solution of choice for deployment of decentralized automation systems.

Keeping jitter to a minimum increases precision Real-time precision requires ac- curate signal timing and simultane- ous signal execution.

SERCOS III of- fers a whole range of new and innovative functions, and it sets the standard for current and future motion control applications. SERCOS has now successfully made the transition from a drive interface to a general-purpose automation network.” Peter Lutz, SERCOS International e. V./Managing Director

“Our flexible tufting machines allow our customers to create innovative patterns and designs, improv- ing their product quality and variation while increasing efficiency and productivity. This requires a fast deterministic machine control system that can easily be modified or updated, while shortening commissioning and startup time through portable programming. SERCOS brings both requirements together, offering the best value as a bus system for our machines.” William Christman, Card-Monroe Corp./Director of R&D

“The system design fits in very well with our philosophy, and that was the crucial factor that tipped the scales in favor of Rexroth. Even back then, Rexroth was able to offer modular system architecture, and that gave us the tools that we needed to do exactly what we had in mind, namely to deliver elec- tronics which every customer can comfortably handle on site.” Werner Oster, KHS AG Packaging Competence Center/Manager Technical Sales/Product Support

“High productivity, reliability and good investment protection are the outstanding features of our system solutions. For us, there is no alternative to top speed, real-time communication and data transfer as well as unrestricted safety, availability and open design. SERCOS offers this unique profile combined with a proven track record in the field.” Dr. Elmar Wings, ProCom Systemhaus und Ingenieurunternehmen GmbH/Engineering Manager CNC Products

“The importance of safe bus systems continues to increase in industrial automation. The SERCOS safety concept is an essential element of modern system design.” Klaus Kemp, TÜV Rheinland Industrie Service GmbH/Project Manager Functional Safety/Software

“SERCOS III is an open communication interface which is used in devices supplied by a range of different manufacturers. Immediate, problem-free device interoperability is only guaranteed if the manufacturers adhere strictly to the specification. On behalf of SERCOS International, we conduct conformity testing on all SERCOS devices in our test lab. Users have the confidence that certified SERCOS devices are truly compatible.” Hans-Peter Bock, ISW, University of Stuttgart/Communications Interfaces Group Leader

“Our customers require maximum availability and fully synchronous operation from our printing ma- chines. Simple, modular design in distributed networks, safety functions and a proven track record for precision are strong arguments which clearly speak in favor of SERCOS as our bus system. Successful implementation of more than 20,000 axes in the field since 1995 confirms us in our conviction that we have made the right choice.” Andreas Birkenfeld, König & Bauer AG/Division Manager Construction System Technology

“A robust real-time communication system is absolutely essential for the excellent print quality and reliability of our ma- chines. The communication system guarantees fully synchronous operation and maximum availability combined with unrestricted productivity. We have decided to use SERCOS which is the established standard in the real-time market.” Harald Bollhöfener, Fischer und Krecke GmbH & Co./Manager Electronic Engineering

Rexroth and the BOSCH Group – a clear commitment to SERCOS III

“We have made a conscious decision to use internationally standardized communi- cation mechanisms and programming languages. That is a fundamental difference between the Rexroth automation system and other products that are based on pro- prietary solutions which protect the systems from competition and keep prices high. That is why we make every effort to support the development of SERCOS III, which combines two standards that are currently very important: the proven real-time mechanisms of the SERCOS interface and the Ethernet physical layer which is used Reiner Leipold-Büttner, throughout the world. We now have an open, high-performance communication Bosch Rexroth AG/Executive Vice President Engineering and system which is supported by a number of drive and controller manufacturers and is Manufacturing being developed further.”

“Customers rightfully expect to get the best automation solutions from the ‘Drive and Control Company’. These solutions are built around a seamless communication system which enables our customers to fully utilize the excellent quality of our products in their applications. SERCOS III is the standardized, leading real-time high-performance bus for sophisticated drive solutions, and it is also the optimal, universal communica- tion solution. Now in its third generation, SERCOS has a proven track record that extends back over many years of practical experience as an industrial-grade bus system. SERCOS is faster, more reliable and less complicated, and it delivers higher precision. SERCOS is also more open. We simply cannot afford to become dependent on the Dr. Karl Tragl, Bosch Rexroth AG/Executive Vice technology and strategy of any single manufacturer. That is why we have firmly sup- President Sales ported the SERCOS interface since day one. SERCOS is standardized from the proto- col to the device data, and it is non-proprietary. The highly intelligent devices in the Rexroth product portfolio offer simple, fully compatible plug & play functionality.”

“In the research and advanced development community within the Bosch Group, we are responsible for coordination of control technology in the plants. A corporate-wide strategy must be based on universal, powerful, uncomplicated and above all non-pro- prietary systems. Following intensive analysis and intensive practical testing, we came to the conclusion that SERCOS III offers unparalleled performance and simplicity. The unique, open, standardized communication strategy offers a significant advan- tage compared to other bus systems which are often dominated by individual manu- Frank Westphal, facturers. That is why we promote the use of SERCOS III as the universal bus system Robert Bosch GmbH/Head of Department R&D Production within the Bosch Group.” Automation
