8. CIP Safety SERCOS safety Profiles Profiles CIP Safety adaptation to CIP Safety SERCOS SERCOS III SERCOS II1) CIP Safety on SERCOS –What is CIP Safety on SERCOS ? • Adaptation to CIP Safety • CIP Safety mechanism and data formats will be adopted unmodified • Minimum implementation of standard CIP (ConnectionManager, Message Router, Identity) on the “grey” level • SERCOS safety Profiles • Description of a Safety Profile (parametersand behavior) with SERCOS parameter 1) won’t be supported by BRC

9. CIP Safety on SERCOS –What is CIP Safety on SERCOS ? • Why to adopt CIP Safety? • Certified and already implemented safety protocol by different communication networks (DeviceNet, EtherNet/IP) means a high investment security • Reduced development costs for component oriented vendors, since multiple communication networks use the same safety stack • World-wide market acceptance by a broad interest group • Safety measures of the different communication networks differ marginally only and do not lead to substantial unique selling points. Furthermore the whole transport mechanism and the overall features of the system are more essential

The SMP header controls the fragmentation or priority of the messages. (Lower priority data packets can be interrupted by higher priority packets)
