  1. Motion, Safety and I/OSERCOS Seminar AtlantaSeptember 16, 2009 Peter Lutz, Managing Director SERCOS International e.V.

  2. Overview • One network for Motion, Safety & I/O • Function-specific Profiles • S/IP • CIP Safety on SERCOS • SCI and FDT/DTM • Components & Products • Applications • Summary (c) SERCOS International 2009

  3. Motivation SERCOS safety and SERCOS I/O (1) • Conventional system topology • Up to 3 different bus systems • I/O bus • Safety bus • Drive bus • Disadvantages • Topology costs • Total Costs of Ownership • Training, maintenance and service safetycontrol MC, PLC I/O bus I/O I/O drive bus safety bus drive motor (c) SERCOS International 2009

  4. Motivation SERCOS safety and SERCOS I/O (2) • SERCOS III • One network for • I/O communication • Safe communication • Drive communication • Additional Ethernet protocols • Optimized solution • Simple topology • Reduced number of interfaces • Unified engineering • Scalable functionality control I/O I/O SERCOS III drive motor (c) SERCOS International 2009

  5. Motion, Safety and I/O • One cable is sufficient … SERCOS III Device Drive Profile I/O- Profile … CIP Safety on SERCOS Cyclic Data Acyclic Data Non- Real-Time Data Ethernet SERCOS III Protocol Ethernet Port #1 Port #2 (c) SERCOS International 2009

  6. Operation modes: Torque Velocity Position Interpolation (absolute position) Positioning (absolute / relative position) Synchronous Mode (spindle drives) Electronic Gearing Additional drive functions: Probing Cycle External Encoder Homing Drive controlled NC controlled Positive Stop Mechanical Parameter Scaling Modulo function others Function-specific Profile (FSP) Drive SERCOS drive profile used for almost 20 years by more than 30 drive suppliers and more than 50 control suppliers (c) SERCOS International 2009

  7. Function-specific Profile (FSP) I/O • Applicable for Block and Modular I/Os • Applicable for hybrid devices, e.g. 2-axis servo drives with I/O capabilities • Based on SERCOS III device model • Compatible to SERCOS III protocol structure • Combinable with CIP Safety on SERCOS for Safe I/Os • User friendly Parametrisation using XML • SDDML (SERCOS Device Description Markup Language) • SPDML (SERCOS Profile Description Markup Language) • Supported by renowned manufacturers (c) SERCOS International 2009

  8. Additional Function-specific Profiles • Encoder profile under development for: • Incremental encoders • Absolute encoders • Basic profile (raw encoder data) and extended profile (scaled encoder data) • Extension of drive profile under development for: • Frequency converters • Hydraulic drives (c) SERCOS International 2009

  9. CIP Safety on SERCOS (1):Coopration between SI and ODVA • Cooperation between SERCOS International (SI) and the Open DeviceNet Vendors Association (ODVA) – announced in Nov. 2006 • Safety concept for SERCOS interface • Safe data transmission according SIL3 • Support of centralized and decentralized safety aplications • Characteristics: • Support of any transmission mechanisms • Routing capability across SERCOS interface and other networks • Single and multi-cast connections • Producer-consumer model • Safe, direct cross communication between SERCOS slaves (c) SERCOS International 2009

  11. CIP Safety on SERCOS (3):Release of Specification • Approval by TÜV and BGIA in March 2008 • Specification released in April 2008 (FSP Safety) • Review by jSIG CIP Safety and TRB of ODVA • CIP Safety Vol. 5 Edition 2.2to be released in 2009 • Update IEC 61784-3 • Cooperation with IXXAT:Development of independentstack software for CIP Safety on SERCOS (c) SERCOS International 2009
