Wireless in Process Manufacturing: Making Progress, with More on the Way

  1. 1. Wireless in Process Manufacturing:Wi l i P M f t i Making Progress, with More on the Way Harry Forbes Senior Analyst ARC Advisory Group y p HForbes@ARCweb.com
  2. 2. Agenda 2007 ARC Best Practices Research Why Multiple Technologies? Current trends, leading applications 2 © ARC Advisory Group
  3. 3. Industrial Wireless ProductsMust Find a “Sweet Spot” Radio Technology and End User interference Requirements rejection ISM RF Application Band vs. Requirements licensed li d (data (d t rate, latency, t l t range, etc.) Device Power Supply Network N t k Long U f l L Useful Protocols Life Network Industrial Topology Environment No single wireless technology solution meets all requirements of all applications! 10 © ARC Advisory Group
  4. 4. Industrial Wireless SolutionsRequire Many Design Decisions Radio Variables Signaling Range PAN LAN MAN WAN (meters) 1-30m 10-100m 100-5,000m 5,000-20,000m Data Rate (kbps) 102 103 104 105 106 Power Supply Self-contained or Rechargeable Mains power replaceable battery (high power) battery (low power) (low power) Radio Spectrum Unlicensed Unlicensed Licensed Sub-1GHz 2.4Ghz Modulation Analog Digital Spread Spread Spectrum Spectrum FHSS DSSS Application Variables Industrial Protected Higher IP ratings Hazardous locations (moisture, dust) location certification Data Sampling 1 Hz 10 Hz 100 Hz 1000 Hz Rates (Hz) Synchronization 1 sec 1 mSec 1 µSec Required 12 © ARC Advisory Group
  5. 5. Industrial Wireless SolutionsDesign Decisions -- Field Transmitters Radio Variables Signaling Range PAN LAN MAN WAN (meters) 1-30m 10-100m 100-5,000m 5,000-20,000m Data Rate (kbps) 102 103 104 105 106 Power Supply Self-contained or Rechargeable Mains power replaceable battery (high power) battery (low power) (low power) Radio Spectrum Unlicensed Unlicensed Licensed Sub-1GHz 2.4Ghz Modulation Analog Digital Spread Spread Spectrum Spectrum FHSS DSSS Application Variables Industrial Protected Higher IP ratings Hazardous locations (moisture, dust) location certification Data Sampling 1 Hz 10 Hz 100 Hz 1000 Hz Rates (Hz) Synchronization 1 sec 1 mSec 1 µSec Required 14 © ARC Advisory Group
  6. 6. Trend:Focus on extreme low-power operation New wireless sensor semiconductor ventures focused on low power operation p p • 2007 GreenPeak Technologies • IEEE 802.15.4 (ZigBee) chips, modules • Optimized for low power • 2006 Gainspan Corporation • IEEE 802.11 (Wi-Fi) chips • Optimized for low power • Existing SoC products reduce power • Dust Networks • Ember • TI 19 © ARC Advisory Group
  7. 7. Less Power Needed by New Radio Modules 20 © ARC Advisory Group
  8. 8. Trend:Self-Powered Wireless Sensor Nodes Super-capacitor Radio Power Micro- Conditioning controller PMG Vibration Energy Sensors Micro-generator g Commercialized 10/2007 (Bently Nevada wSIM) Power supplies are ATEX certified 21 © ARC Advisory Group
  9. 9. Wireless Field Sensing Commercial products since 2003 Longer life More reliable communication Better security Soon standards-based • IEEE 802.15.4 • HART V.7 (WirelessHART) • ISA SP100 24 © ARC Advisory Group
  10. 10. Wireless Condition Monitoring - Future Sensors include energy harvesting Low i t ll ti L installation cost t Data capture can be fully automated Data analysis can be fully automated Will extend monitoring to important p p plant assets Can be installed on existing plant assets Requires network infrastructure 27 © ARC Advisory Group
  11. 11. Summary: Things To Remember Wireless can yield huge value, but not without effort Process plants will always use many different forms of wireless Wireless product introductions will continue to accelerate 31 © ARC Advisory Group
