Benefits

Dedicated to safety. Some systems from other

vendors use the same networks for both control and

safety. The DeltaV SIS LSN and GSN are dedicated to safety,

carrying only safety-rated signals and isolated from the

control network. They are therefore immune to any failure

of the control network.

Fifty millisecond update time. All the data broadcast on the

LSN is available to every CSLS on the same LSN every

50 milliseconds. Combined with the speed of the CSLS,

the 50 millisecond update time guarantees input-to-output

time of less than 300 milliseconds anywhere on the LSN

when the CSLS is configured for 50-millisecond scan rate.

Plug-and-play components. As a dedicated safety network

with predictable communications traffic, Emerson has done all

of the system testing so you only have to plug the components

together to create the safety networks.
