Plant Asset Management
 Why Plant Asset Management?
Currently Plant Asset Management
focuses on instrumentation performance
What about the infrastructure for the
instrumentation?

Enabling Factors with FF
•Increased intelligence closer the process
•online performance indication through process &
device diagnostics
•increased process stability
•Improvements
•increasing plant availability
•increasing productivity and product quality
•less raw & waste material
•During longest lifecycle period of the plant: operation

Life Cycle of Fieldbus Physical Layer:
 Design
Environment
Bus topologies
Component selection
 Commissioning
“great view at the abyss”
A new view to the physical layer “black
hole”
 Operation
Modification
Expansions
Maintenance

Environment of the Fieldbus Infrastructure
 Fieldbus Installations have to resist a lot of
influences
 the drop of signal-quality of older field devices
 degrading of shielding, earthing and grounding
 noise & ripple, caused by other peripheral
devices, causing a drop of signal quality and
interfere communication
 negative effects of temperature, humidity, UVlight, vibrations
 These are well known effects and their
influence needs to be reduced by
monitoring the fieldbus physical layer – no
more “black hole”

Why HSE for the Diagnostics?
 Separate bus recieves diagnostic information regardless of DCS
 Vender neutral protocol
 Integration of Ethernet-based networks into FF-system architecture
 FF-Function blocks
 FF-Alarms
 Ethernet – Accepted Physical Layer
 Use of standard ethernet hardware
 Virtually Unlimited number of stations are possible
 Virtually Unlimited Ethernet Network length
 High transmission speed of HSE
What are the Online Diagnostics?
 Monitoring electrical values including alarming
