Process

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.

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

Jumper / configuration

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 projectsOver 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 installedOver 13 Million PROFI nodes installed

Easy-to-use due to robust support toolsGetting easier to implement for sensor/actuator manufacturersGetting less expensive to implement, but costs are driven by volume
