  1. Mini-Fieldbus Components CPAC/NeSSI Workshop May 5, 2005, Seattle,WA by Softing North America Ken Hoover

  2. The Softing Group • Softing AG • Softing GmbH, founded 1979 • IPO, 1999 • Traded, Frankfurt Stock Exchange • Offices in Munich, Düsseldorf • Softing North America, Inc. • Incorporated in 2001 • Headquarters, Newburyport, MA • More than a decade of service in the US • Softing Romania • Formed, February 2005 • Product Development

  3. Employees • 160 employees • 95 active in R&D

  4. Analysis Tools OPC Technology Ethernet Softing -- a recognized world leader in the key technologies of industrial communications Fieldbus Products Based on Open Standards

  5. Technology Expertise • Industrial Fieldbuses • Protocol stacks • Device development • Diagnostic software • Hardware interfaces • Ethernet Gateways • OPC (Software Bridges)

  6. ABB Alcatel SEL Bosch E & J Gallo Endress+Hauser Fisher-Rosemount Ford Motors Foxboro GAO General Motors Honeywell Krohne Krones Limitorque Matshushita Miller Brewing Mitsubishi Opel Pepperl+Fuchs Schlumberger Schneider Electric Siemens StoneL Swagelok Tetra Pak Valmet Automation Yamatake-Honeywell Yokogawa Electric Our Customers

  7. Device (sensor/actuator) manufacturers System suppliers Services geared toward automation suppliers

  8. Services geared toward automation suppliers • Portable communication protocol stacks • FOUNDATIONTM fieldbus • PROFIBUS • CANopen • DeviceNet • Ready-to-use hardware architecture • PC boards for fieldbus systems • Reference platforms • Customizable gateways

  9. Fieldbus-enabling a field device Process Transducer Block Fieldbus-ASICs Sensor/Actuator SPC 4.2 AI PID AO Frontier 1+ Function Block Shell Basic Field Device Stack Find 1+ FF H1 Network

  10. Three steps to fieldbus/device integration Step 1: • License Softing’s hardware schematics, stack, function blocks • Modify form factor of existing hardware to meet requirements • Submit design to Softing for review • Jointly approve software specification Step 2: • Manufacturer produces prototype units and submits to Softing • Softing performs hardware tests • Softing adds protocol stack and function blocks to hardware Step 3: • Integrate device application and connection to device. • Certify device at certification authorities. Today 2 Months 3 Months

  11. Results: • It takes at least 3 months • It is costly ($100-300K) • Device manufacturer must evaluate ROI • May decide not to participate in market • May hold off until technology progresses

  12. A solution: Fieldbus OEM Kit New! November, 2004 Existing HART or analog sensors/actuators

  13. 3V 5V A solution: Fieldbus OEM Kit User interface Debug interface Reset circuit Jumper / configuration UART I2C SPI CPU M16C62P 31kB RAM 384kB Flash 4 SRAM 128k x 8 Databus D[0..7] A[8..18] A[0..16] Address latch A[0..7] AD[0..7] AI/AO (je 2x) Fieldbus Controller Find1+ A[0..4] serial (I2C) FRAM 128kBit/256kBit AD[0..7] multiplexed Adress/Data DI/DO (8x) 4 MDS MAU Interface 3V 5V (20mA) FieldbusPROFIBUS PA FF IEC-H1 MAU Protection EMV Protection EEx

  14. Fast integration of existing sensor/actuators • Good for Intrinsically and non-Intrinsically Safe environments • Provides easy electrical connection to the existing device hardware • Ready-made templates are customized, providing unique features to the application-specific sensor/actuator • Building the required Device Description files is included in the kit

  15. Results since introduction: • Just completing our fourth US implementation. • Prototype sensors implemented in as few as two weeks. • Cost of integration has been cut to one-fourth of previous costs. • Device manufacturer can participate in fieldbus market with much less risk.

  16. Unique requirements for NeSSI adoption: • Sensors/actuators are inexpensive • Cost of implementing fieldbus technology is high relative to cost of actuators • Sensor/actuator manufacturers are still unsure of ROI • Size of hardware is still too large.

  17. Some possibilities: • Reduce footprint of hardware interface • New, smaller fieldbus ASICs • Re-tool board to ¼ its size • Cost of components is driven by volume • Present low volume solution: $450 per board, $30K development/integration service including certification • Future scenario: $80-100K to re-tool board, price per board totally dependant on volume.

  18. Summary • Softing has vastexperience doing customer-specific projects • Over 50% of the FF-certified devices have “Softing Inside” • We have a worldwide installed base of over 30,000 fieldbus interfaces • Fieldbus technology is: • Proven and pervasive • Over 500,000 FF compliant devices installed • Over 13 Million PROFI nodes installed • Easy-to-use due to robust support tools • Getting easier to implement for sensor/actuator manufacturers • Getting less expensive to implement, but costs are driven by volume
