8. Dupline Specialist Seminar 2005 8Jens Neigaard DuplineSafe vs. series wired safety circuit 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 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 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 Precise diagnostics which can be read from a PLC, PC or Text Display No problems with contact resistance due to short input leads No problems with contact resistance due to short input leads Safety Output module Contactor Tx Safety Input modules Contactor PLC/ PC/ Text Display Gateway Profibus-DP or Modbus Channel Generator 0 VDC 24 VDC 0 VDC 24 VDC

10. Dupline Specialist Seminar 2005 10Jens Neigaard 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

11. Dupline Specialist Seminar 2005 11Jens Neigaard Communication Concept

12. Dupline Specialist Seminar 2005 12Jens Neigaard The Safety Modules - Can operate on existing Dupline system - Can be used together with standard Dupline modules Combined Solutions
