1. Progress and Developments in Network Solutions for NeSSI Generation II CPAC May 2005 John Mosher – Honeywell Sensing & Control

2. Physical Interface “Rail” – ANSI/SP76 Communications Interface “Rail” The Area Between the Enabling “Rails” is Where Sensor and Instrument Vendors Add Value and Commercialize Intellectual Property. The Network “Rail” Enables Information

3. NeSSI-Net NeSSI Generation II Network Requirements:NeSSI Generation II Network Requirements: - Intrinsically Safe - Multi-variable Capability - Configuration Storage and Update Capability - Diagnostic Capability - Connectivity to Sensor Actuator Manager (SAM) - Fault Tolerance - Protocol administered independently (not by NeSSI/CPAC) - Open System - World-wide acceptance - Petrochemical market acceptance - Key customer acceptance The Network Enables Information and Uptime

4. The Fieldbus Foundation: - Offered to help with Specification Definition - Will coordinate resources with NeSSI product vendors - Offered Technical Assistance in Implementing FF - Understands Vision for MicroAnalytical Platform - Free Device Conformance Testing Foundation Fieldbus Foundation Fieldbus Chosen for Generation II/III - Proposed, discussed and accepted at CPAC Fall Meeting - Meets all criteria of requirements - Minor engineering work to shrink network interface - Press Release Issued at Foundation Fieldbus General Assembly

5. Foundation Fieldbus Value: FF delivers benefits today - Wiring and cabinet savings - Asset management for lower maintenance and fewer incidents - Faster startup, commissioning, maintenance Fieldbus supports a rich set of capabilities - Control on the wire (the only protocol that has it) - Automatic Addressing - Automatic Configuration via Electronic Data Descriptions - Automatic Replacement Device Configuration - Built-in Alarming - Function Blocks for Simple Device Management - Seamless Data Transfer with FF HSE (High Speed Ethernet)

NeSSI-Net Future Directions Room for Improvement? - Extended Temperature Range - Improved FISCO Node Count - ProfiBus PA NIST Program - Intrinsically Safe CAN bus - Working Group Established - Adoption of CANOpen - Definition of Physical Layer - Prototype in Development - IS Certification costs Discussed The Network Enables Information and Uptime

11. Honeywell Foundation Fieldbus New Experion R300 Series C Foundation Fieldbus Module 4 Fieldbus H1 channels Fully Redundant Configuration available 100 Mbps to Experion Controller or directly to Server

12. DoE Sensor Project Update

13. DoE Project Delayed by Funding Issues Phase One includes 2 NeSSI Units Scheduled for PHASED Participants in Q4 Phase Two Funding Reduced No NeSSI Units Currently in Phase Two Overall Project Schedule may be Extended to 5 Years from 3 Initial System will be short of Gen II Specs Need Input from Participating Users on Acceptance of ‘Build-up-to’ Gen II approach DoE Project is No Longer a Catalyst for NeSSI Gen II/III Development. DoE Project Update
