  1. Fieldbus Physical Layer as an Asset Randy Durick Business Development Manger TURCK Inc. Mile High Industrial and Automation Conference

  2. Plant Asset Management • Why Plant Asset Management? • Currently Plant Asset Management focuses on instrumentation performance • What about the infrastructure for the instrumentation? Mile High Industrial and Automation Conference

  3. Traditional Analog Circuits Only 1 value is transmitted Only one direction 4-20 mA Mile High Industrial and Automation Conference

  4. 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 Mile High Industrial and Automation Conference

  7. What About the Infrastructure? Mile High Industrial and Automation Conference

  8. Physical Layer Diagnostics Temperature ? Ripple ? Multi-barrier Voltage ? Power Conditioner Busload ? Current ? EEx-e Jitter ? Noise ? EEx-i Mile High Industrial and Automation Conference

  9. 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 Mile High Industrial and Automation Conference

  10. 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” Mile High Industrial and Automation Conference

  11. Fieldbus Physical Layer Diagnostics Maintenance HSE FD ∑ 4 Power Conditioner Multi-barrier Power Conditioner EEx-e EEx-i Mile High Industrial and Automation Conference

  12. Advanced Diagnostic Unit Fieldbus Physical Layer Diagnostics Maintenance HSE FD ∑ 4 Power Conditioner Multi-barrier Power Conditioner EEx-e EEx-i Mile High Industrial and Automation Conference

  13. 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 Mile High Industrial and Automation Conference
