Plant Asset Management

Why Plant Asset Management?

Currently Plant Asset Management focuses on instrumentation performance

What about the infrastructure for the instrumentation?

Traditional Analog Circuits

March 31st and April 1st, 2009 Mile High Industrial and Automation Conference

4-20mA

Only 1 value is transmittedOnly one direction

Enabling Factors with FF

March 31st and April 1st, 2009 Mile High Industrial and Automation Conference

•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

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”

Fieldbus Physical Layer Diagnostics

March 31st and April 1st, 2009 Mile High Industrial and Automation Conference

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

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
