Safety included – CIP Safety on SERCOS

Safety included – CIP Safety on SERCOS is the protocol which is used to transfer safetyrelated data on the SERCOS interface. It was defined in collaboration with ODVA and has been certified for compliance to IEC 61508 up to SIL 3. There is no need for an additional safety bus, because the safety information is sent in addition to the standard data on the SERCOS interface network in real time. The combination of drives, peripherals, safety bus and standard Ethernet in a single network simplifies handling and reduces hardware and installation costs, and it makes it easy to deploy integrated safety controllers and homogeneous safety solutions.
Principle CIP Safety on SERCOS

CIP Safety on SERCOS means:
  • the CIP Safety standard is used as the functional safety protocol
  • CIP Safety adapted to SERCOS
  • SERCOS-specific safety profiles

With CIP Safety on SERCOS, the data is sent on the same medium using the same connection as standard communication. Reliable communication can take place between all network levels including peer-to-peer communication and cross-network communication. The master does not necessarily have to be a safety controller. It can also route data without being able to interpret it. Safety-related data is sent in a safety data container which is placed on the real-time data channel (MDT and AT) similar to standard data.
Embedded safety datas

The safety-related data is transferred in a safety-data-container. Like the standard-data it is integrated in the correspondent real-time device channel in AT and MDT.

The combination of drives, peripherals, safety bus and standard Ethernet in a single network simplifies handling and reduces hardware and installation costs, and it makes it easy to deploy integrated safety controllers and homogeneous safety solutions.
