Current Application

New TWG structure at Sercos International

Since the foundation of the Sercos user group in 1990,15 to 20 member companies continuouslycontribute to the further development of the Sercos technology. The technical work in recent years has been mainly focusing on the migration from a dedicated digital drive interface to an universal automation bus for diverse applications in machinery and plant engineering, as well as beyond.

With the implementation of Industry 4.0 concepts and the associated convergence of IT and automation, Sercos International is restructuring the Technical Working Groups (TWGs) and is bundling the relevant Sercos® topics in three working groups. This results not only in a fast and efficient reaction on market demands and technology trends. Furthermore, the drafting of the Sercos specifications and the inclusion of these specifications in international standardization will be accelerated accordingly.

The TWG Communication focusses on communicationrelated topics, such as the Sercos real-time protocol, the IP communication, and hardware issues. Associated with this working group are new technologies and trends, such as IEEE 802.1 Time-Sensitive Networks (TSN) and security. This TWG is headed by Florian Ruhhammer (Schneider Electric Automation) and Denis Janssen (Hilscher).

The TWG Devices is responsible for the maintenance and further development of the Sercos device profiles. This includes among others the generic device profile (GDP) and the function-specific profiles for decentralized I/Os, encoders, electrical, pneumatic and hydraulic drives, as well as power sections of electrical drives. This TWG is headed by Dr. Andreas Selig (Bosch Rexroth) and Marcus Würr (Schneider Electric Automation).

The TWG Application and Tools deals with application-specific topics as well as with software tools. Application-specific topics include energy management (Sercos Energy), functional Safety (CIP Safety on Sercos), as well as the mapping of the Sercos technology to OPC UA. In addition, the working group is responsible for the coordination of the development of Sercos-related software tools (such as Sercos Conformizer, Sercos Monitor and Sercos Configurator). This TWG is led by Volker Lutz (Phoenix Contact) and Dr. Stephan Schultze (Bosch Rexroth).

The Sercos Steering Committee (SSC) is the superimposed body which coordinates the technical work in the TWGs in close coordination with the working group leaders, the Marketing Working Group (MWG) and the Board (BoD) of Sercos International. The SSC is headed by Peter Lutz (Sercos International).
