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

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

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

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

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.

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.

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.

Summary  Softing has vast experience 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
