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,
  UV-light, 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

14
What are the Online Diagnostics?

• Monitoring electrical values including alarming
• voltage level bus power supply
• ambient temperature
• segment current load
• ripple
• noise
• jitter (each device)
• signal level at each device
• Monitoring communication values
• address/ live list for devices on the segment
• Communication statistics
• frame errors
• PDU (protocol data units)
• bus idle times
• cyclic and acyclic communication
