DeltaV SIS Safety Network Components
The local safety network (LSN) is the communication backbone of the DeltaV SIS process safety system.
  The global safety network (GSN) enables safety-rated communication among LSN’s while allowing functional segregation on different LSN’s.  The GSN can be logically separated in domains which are a group of LSN’s.


  • Dedicated to safety – no possibility of common-cause control and safety communication failures
  • Required update time supported on the DeltaV SIS local safety network
  • Scalable and cost-effective
  • Fully redundant networks
