  4. 4. International field bus and safety standards for factory automation PROFIBUS covers both factory & process automation PROFINET - based on standard ETHERNET - is its complementary network • 1999 first specification for safety communication called PROFIsafe. • PROFIsafe has evolved to become the leading and most comprehensive safety communication technology in the world. • Developed to IEC 61784-3-3, PROFIsafe is now the International Standard • Evaluated by TUV and BGIA
  5. 5. The “PROFIsafe” Protocol • Safety messages transmitted on existing standard bus cables in coexistence with the standard messages. • Total independence from the base transmission channels be it copper wires, fiber optics, wireless, or backplanes Safety measures include: The “Black Channel” principle • The consecutive numbering of the PROFIsafe messages ("sign-of life") • A time expectation with acknowledgement ("watch-dog") • A codename between sender and receiver ("F-Address") • Data integrity checks (CRC = cyclic redundancy check) PROFIsafe message format
  6. 6. Certified Safety Output CH A Pulse Check Output Signal Positive switched Data CRC 001100011100 uP uP 1 1 O One Output channel 0 Read back Decentralized I/O Ground Switched uP 2 Input data Read back CPUs Cross Check Each Other! Failsafe I/O modules protect locally & simplify the design and wiring, Even if the PLC and Network Fail, the I/O Module can go into Safety Lockout

  14. 14. Safety Market Overview • Available Safety Protocols o o o o o ProfiSafe CIPSafety Safety EtherCAT Safety Net p openSAFETY is limited to Profibus and Profinet is limited to EtherNet/IP and SERCOS is limited to EtherCAT is a proprietary protocol from PILZ is open and available for any fieldbus • openSAFETY is fully open and totally independent of the fieldbus!
  15. 15. Concept of openSAFETY • Any Brand - Any Bus - One SAFETY standard your HMI brand any SAFE PLC your PC brand your PLC brand Your PANEL brand your IO brand your motion brand
  16. 16. Safe line communication
  17. 17. openSAFETY • Independent, 100% open, and License free technology • Approved as worldwide standard IEC61784-3 • TÜV certified protocol – IEC61508/11 SIL3, PL e, Cat 4 • One single Safety Standard for the complete production line
  18. 18. Reference Model • openSAFETY includes all necessary services and interfaces to the Safety Application
  19. 19. Communication Model • openSAFETY makes use of the producer / consumer communication model
  20. 20. Communication Model • openSAFETY provides an extended version of the producer / consumer communication model allows the producer to produce separated data for individual consumers
  21. 21. Communication Model • openSAFETY server client communication. Mainly used for configuration services and network management
  22. 22. Errors and Preventive/Corrective Measures • No faults go undetected !
  23. 23. Frame Structure • The frame consists of two sub frames and is able to transport data up to 254 bytes of payload data
  24. 24. Total Flexibility • openSAFETY domain and gateway allow the safety through different network architect
  25. 25. openSAFETY for Component Manufacturer • One time development investment o same safety standard for all fieldbuses • Reduced development time o Certified openSAFETY stack available • Investment security o legal and technical independence o open source protocol stack • Easy certification o TÜV certified conformance test o guaranteed interoperability
