Regulations
Business Context
Safety Instrumented Systems should remain independent from process
control systems to prevent common cause failures. Modern facilities,
however, increasingly share communication networks, engineering
workstations, and diagnostic platforms to improve operational
efficiency.
The Contradiction
Greater independence improves functional safety.
Greater infrastructure sharing improves operational efficiency.
Why It Exists
Shared digital infrastructure reduces cost and simplifies engineering
but may introduce dependencies capable of affecting both operational
control and safety functions simultaneously.
Direction
Maintain independent safety architectures while using secure, controlled
interfaces that allow information sharing without compromising
functional independence.
