1. Oil, Gas & Petrochemicals CementChemicalsMetals & Minerals Life Sciences UtilityAutomotive An Integrated Analytical Process GC and SHS Based on IS CAN Communication ABB Analytical Tracy Dye Circor Tech Patrick Lowery

2. Vision Revisited A self reliant process analytical system that receives, sends and acts on multivariate data to monitor, communicate and control its status and health via any networked client.

3. NeSSI TM Value Proposition Revisited Improved System Reliability and Serviceability Reduced Capital Costs Reduced Operational and Maintenance Costs

4. IS CAN for the NeSSI TM Communication Bus “Plug and play” in Div 1/Zone 1 classified areas CAN is everywhere in demanding applications (marine, auto, aerospace) Balanced signaling (differential drive) enables superior noise rejection (relative to unbalanced single end) especially over cables Open and Standard, already built in … Data Integrity Mechanisms Integral Bus Error Recovery and Self Correction Message Prioritization Via Non-Destructive Arbitration Mature and Well Defined Application Layers Such As CAN Open

5. Basic System Topography

6. Two Application Steps Step 1 (Without SAM) Hybrid communication system Discrete analog outputs for single signal devices Discrete digital inputs IS CAN networked components for multivariate data devices Basic control Temperature, flow, filtration backup, valve switching Basic indication Sample flow, ΔP, temperature

7. System Prototype Layout for Application Step 1 F/O IS CAN

8. Two Application Steps Step 2 (With SAM) ‘Self Describing’ System All SHS components have open standard description file (EDDL?) Real time operational view of SHS on any networked client Fully integrated process analytical system

9. Progress and Path Forward IS CAN physical layer is a reality backed by a standard (CiA 103) SHS components with IS CAN communication are available Realization of the NeSSI TM vision with a controlled cost, two step approach Step 1 in Q1, 2008 Step 2 in 2009
