  1. NeSSI* - Generation II “Revolution or Evolution?” *New Sampling/Sensor Initiative CPAC - November 5-8, 2001 Rob Dubois - Peter van Vuuren - Jim Tatera . Tatera and Associates “the best way to predict the future is to create it”

  2. The Recent History of • ISA2001 Meeting (Joint ISA/CPAC Session) • NeSSI Tutorial Standing Room Only Interest Public Introduction of Generation II Specification • Open Discussion Session (Sept 11 Impact) Main Issue - Area Classification Requirements Identified X-Team to address • Ad-hoc Sensor Connectivity Session CAN-based protocols (e.g. SDS, DeviceNet) best candidates A C-team will clarify benefits of CAN and propose as preferred NeSSI sensor communications standard • MiscellaneousEfforts afoot to extend SP76 to IEC standard NeSSI Tutorial at INTERMAC Meeting in Japan (Nov 8) - Rob DuboisNeSSI Marketing Survey Underway

  3. Legacy NeSSI Hot Off The Press

  4. Major Goals of • Facilitate the acceptance/implementation of... • modular, miniature & smart sample system technology • based on ISA SP76 standardization work • Promote the concept of... • field-mounted smart sampling/analytical systems • integration of sample systems with physical/chemical sensors • Lay the groundwork for... • open connectivityarchitecture for sensor communications (e.g. Ethernet, DeviceNet, etc.) • industry standard communicationprotocols (e.g. OPC, DeviceNet, CAN etc.) • web enabled technologies (e.g. Browser based HMI) • Provide a technology bridge to the process for... • “sensor/lab-on-a-chip” micro-analytical devices

  5. NeSSI Generations • NeSSI Generation I (circa 2000-2002) • mechanical, passive components are on a SP76 substrate • NeSSI Generation II (circa 2002-2004) • “electrified” passive & active components are on a SP76 substrate • integral heating and temperature control of the substrate • all electrical components are integrated with SAM • sensors and actuators communicate via sensor bus • smart (self-diagnostic) sample systems • NeSSI Generation III (circa 2003+) • many analytical sensors and micro-analytical systems • wireless sensors
