  1. SIL 3 DuplineSafe Jens Neigaard

  2. DuplineSafe Idea • To seek approval for Dupline as a Safety Bus according to: • EN61508 (SIL 3) Functional safety of electronic systems • EN954-1 (Cat 4) Safety related parts of control systems • EN81–1 (Cat 4) Elevator safety norm Jens Neigaard

  3. Why do we need these approvals ? • We have existing customers demanding it • We have new potential customers demanding it • The approvals will open new markets for Dupline • The general image of Dupline will be improved • Synergy with the Safety Product Group • The trend in the Fieldbus market is going in this direction- and we must continue to develop our technology to keep pace Jens Neigaard

  4. How can we compete with open Safety Buses like ProfiSafe, SafetyBus and ASI-Safety ? • Dupline has some unique features which make the system very suitable for certain safety applications: • Dupline can handle long distances • Dupline is noise immune and reliable • Dupline is simple • Dupline modules can be powered from the bus • Dupline input module can be ATEX approved Jens Neigaard

  5. Traditional safety circuit with series wired NC Contacts • Problems: • Shorted contacts create an undetected loss of safety function • No diagnostics • Resistance in contacts becomes a problem over time Safety Relay Contactor 0 VDC 24 VDC Contactor 0 VDC 24 VDC Jens Neigaard

  6. Traditional parallel wired safety circuit • Problems: • Wiring cost • Limited number of inputs • Lack of flexibility Safety Relay Contactor 0 VDC 24 VDC Contactor 0 VDC 24 VDC Jens Neigaard

  7. 0 VDC 24 VDC 0 VDC 24 VDC PLC/ PC/ Text Display Gateway Profibus-DP or Modbus Channel Generator The DuplineSafe Solution Safety Output module Safety Input modules • Standard Dupline Channel Generator • Buspowered Safety Input Modules • Configurable Safety Relay Output module • Diagnostic information via PLC, PC or • Text Display • Up to 63 safety signals on one Dupline bus Contactor Tx Tx Contactor Tx Tx Jens Neigaard

  8. 0 VDC 24 VDC 0 VDC 24 VDC PLC/ PC/ Text Display Gateway Profibus-DP or Modbus Channel Generator DuplineSafe vs. series wired safety circuit Safety Output module • The risk of a dangerous short circuit is much lower because all short circuits on the bus are either detected or have no impact on safety function • Only risk is input leads, but these are very short due to the vicinity of the input module • Precise diagnostics which can be read from a PLC, PC or Text Display • No problems with contact resistance due to short input leads Safety Input modules Contactor Tx Tx Contactor Tx Tx Jens Neigaard

  9. 0 VDC 24 VDC 0 VDC 24 VDC PLC/ PC/ Text Display Gateway Profibus-DP or Modbus Channel Generator DuplineSafe vs. Parallel wired safety circuit Safety Output module • Reduced wiring cost • Higher number of inputs possible • (up to 63 input modules) • Higher flexibility for enhancement of a system Safety Input modules Contactor Tx Tx Contactor Tx Tx Jens Neigaard

  10. Communication Concept • The synchronization channel is toggling every Dupline cycle (controlled by safety output module) • The status of each input is transmitted is on 2 different Dupline channels • The transmission is dynamic with the bits toggling every Dupline cycle • When the input contact is closed, channel 1 follows the sync channel, channel 2 is reverse. When the input contact is open it is the opposite Jens Neigaard

  11. Communication Concept Jens Neigaard

  12. Combined Solutions • The Safety Modules • Can operate on existing Dupline system • Can be used together with standard Dupline modules Jens Neigaard

  13. The DuplineSafe Approval • Approved Products: • Safety Input Module • (GS75102101) • Safety Relay Output module • (GS38300143) • Approval according to: • IEC 61508-SIL3 • EN954-1 Cat. 4 • Pending: • EN81-1 Jens Neigaard

  26. Advantages Jens Neigaard

  27. Advantages Jens Neigaard

  28. Target Applications • REPLACEMENT OF SERIES WIRED EMERGENCY STOP SYSTEMS: • Much safer • Diagnostics reduce downtime • Several safety relays at different positions can react on the same safety switch Safety Relay Contactor 0 VDC 24 VDC Contactor 0 VDC 24 VDC Jens Neigaard

  29. Target Applications • Application requirements to our advantage • Long distances • Widespread safety switches • No local power supply available at safety switches • High reliability / noise immunity demanded • Simplicity in design, installation and commissioning demanded • Frequent system changes • Application requirements to our disadvantage • Ultra-fast reaction-time needed • (not needed for buttons / pull-wire) • Advanced safety functions needed • (e.g. Safety PLC with programmable logic functions) • Open system specified Jens Neigaard

  30. Target Applications • Application examples • Long bulk material conveyors • Tunnels • Mines • Stone Mills • Power Plants • Cement Factories • Conveyors used in sorting systems • Airports • Postal systems • Automated Logistics Systems • Wood Works • Cranes (sliding contacts) • Automatic door systems (e.g. big stock facility) • Elevators (when EN81-1 approval is ready) • Chemical plants (especially when ATEX approval is ready) Jens Neigaard

  31. Competitors • Safetybus-P (Pilz) • ProfiSafe (Siemens) • ASI-Safety at work (Siemens, Schneider, Turck ..) • Interbus Safety (Phoenix) • Devicenet Safety (Rockwell) • SafeEthernet (HIMA) Jens Neigaard
