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

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

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

• 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

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

SYSTEMS:
• Much safer
• Diagnostics reduce downtime
• Several safety relays at
different positions can react
on the same safety switch

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
