Safety Network Protocols

Feb. 2, 2012
The term “safety network” can apply to both peer-to-peer networks and I/O bus systems, and the safety protocols used can range from proprietary to various levels of open or vendor-independent. Here are some safety protocols and the industrial networks they are associated with:
  • AS-Interface Safety at Work (also called AS-i Safe) on any network
  • CIP Safety on EtherNet/IP, ControlNet and DeviceNet networks
  • ProfiSafe on ProfiBus and ProfiNet networks
  • openSafety on Ethernet Powerlink and other networks
  • Functional Safety over EtherCAT (FSoE) for EtherCAT networks
  • FF-SIF on Foundation Fieldbus networks
