NeSSI? Industry Vision Gen III what are
the next steps?

• Discussion Moderator Rob Dubois

Agenda

• A recap of industry visions. Is NeSSI in
  alignment?
• Gen III microAnalytical
• issues and barriers
• Gen III specification
• what information is needed?
• Gen III implementation
• what could CPAC do to enable the development of
  microAnalytical devices?

1. Industry Visions is NeSSI in alignment?

• NAMUR, VDI/VDE-GMA (Roadmap for Process Sensors
  2005-2015)
• All physical and chemical data are available at
  any time by all equipment parts and processes
• Measurement takes place without interference in
  the process
• The measured values are available in real time
• Ideally sensor systems function without
  maintenance, calibration and adjustment
• The sensor systems are inexpensive

• NIST/ATP Vision 2020 (Process Measurement and
  Control 1998-2020)
• Develop technology to provide smart sensors for
  all process measurement
• Develop tools to diagnose faults in real-time
• deliver modular systems both in hardware and
  software.
• Develop devices to minimize maintenance
  including self-diagnostics, fault detection,
  minimized service requirements and the capability
  for in-situ standardization and calibration.

2. Gen III what are the Issues Barriers?
(notes)

• Can/should the NeSSI-bus be used to transfer high
  intensity data (spectra and chromatograms)?
• one can send just send key information, quality
  factors
• can be done
• keep open ended should be able to handle large
  amounts information
• CAN can handle high intensity data
• data speed is not critical in many applications

Different Implementation Model for
microAnalytical

• B Type
• non-modular
• NeSSI-bus used for communication
• can use power externally or from the bus
• EExd enclosure

• A TYPE
• modular
• bus power and comm.
• Intrinsically Safe

3. What would be required in a Gen III document?
(notes)

• Detailed specification is not required
• Need Development phases
• macro to micro
• Interfaces described to allow Intellectual
  Property to flourish between the rails
• Have inventors concentrate on microAnalytical
  measurement not packaging and communication
• Provide connectivity model

Could we employ a phased Development?
low power smallest disposable robust/self-diagnost
ic redundant

4. Gen III Implementation (notes)

• What could CPAC do to enable the development of
  microAnalytical devices?
• a clearing house for microanalytical
• further definition needed
• use of the terms microlytics and sensometrics for
  small devices
