• Significance of level 2,
more displays, mainly
used for monitoring
but also for controlling
• Several detailed views
on the same plant

temporarily
for start-up,
diagnostics etc.

Flexible Redundancy at all levels
• Scalable for different applications
(ESD, HIPPS, F&G etc.)
• Controller redundancy for availability
.. not required for safety
• Physical separation to combat
common cause
• Flexibility to accommodate different
SIF architectures so …
• Field device redundancy can be
designed to achieve safety and
availability goals
• I/O redundancy independent of CPU
