  9. NeSSI Generation II What is Generation II? NeSSI II = SP76 + IS + CAN + SAM SP76 = NeSSI Generation I from SEMI IS = Intrinsic Safety CAN = Controller Area Network – DeviceNet SAM = Sensor Actuator Manager – Open Interface to Plant-wide Network and/or Analyzer Reliable, Networked, Modular, Safe, Open, and Affordable!

  11. NeSSI Generation II • PROJECT ABSTRACT • The Problem: Need for a networked, standardized, int.safe, modular, affordable and reliable process stream sampling and sensor system. Sampling systems now are causes for down-time and questionable process stream samples followed by costly control errors. • Objectives are to: •  Accelerate development of the prototype system component • such as intrinsically safe, digital pressure, temperature and • flow (p, T, F), sensors, smart valves, flow-controllers, and a • sensor/actuator networking capability •  Build, demonstrate, and test 1-2 NeSSI-II units, and •  Provide a platform for incorporating analytical sensors right • into the sampling system.

  12. ABSTRACT (cont’d.) Benefits Enabled by Full NeSSI Implementation:  Reduce down time, energy use & operating & sampling cost: U.S.: 0.1-0.2 Q/y or $10-20 billion  Bring these savings to the end-users at an earlier date, and  Reduce the business risk to the Supplier and End-User End-Users are members from across the processing industries: chemical, petrochemical, power generation, refining, food, beverage and dairy, pulp & paper Schedule:  One year for design, build and lab-test  One year for installation and field testing Deliverables:  Interim and Final Reports (no hardware) on design of sensor hard- and software, NeSSI test results, benefits and recommendations Management of the Program: Honeywell + Consortium

  16. ISO OSI 7-Layer Model Application Layer Presentation Layer Session Layer Transport Layer Network Layer Data Link Layer Physical Layer CAN Communications - Issues and Background • Issues/Questions: • 1. Is it feasible to embed all required device electronics, • microcontroller, and CAN communications into a NeSSI • SP-76 1.5 x 1.5” footprint? • 2. Is a CAN network capable of operating through an IS barrier? • Selection of CAN as a communications enabler for NeSSI • High Level Protocol • SDS, DeviceNet, CANOpen - all publicly available & proven • Data Link Layer • Master/slave, peer-to-peer, multicast messaging • All data types supported • Diagnostics • Carrier Sense Multiple Access with Collision Resolution • 16-bit CRC error checking, intell.network mgmt.capability • Physical Layer • Trunkline/multidrop with branches • Separate twisted pairs for signal and device power distribution • Up to 64 nodes, up to 500 meters trunk length • Intrinsic Safety

  17. Adaptation of Honeywell Temperature, Pressure, & Flow Sensors to NeSSI design standards. • Microbridge flow sensor interfaced to a typical miniature CAN microcontroller and 12 mm connector. • A similar interfacing • approach will be used in this project to connect existing sensors and actuators to • the CAN network. 12 mm by Bob Nickels, Honeywell

  18. CAN Communication - Feasibility and Intrinsic Safety Evaluation • DESCRIPTION OF TESTING: • Lab tests utilized SDS protocol and devices • A standard Zener Intrinsic Safety Barrier was used in series with both CAN communication signals. Component values were varied down to 4.3 volt Zeners and up to 100 ohms of series current-limiting resistance • 20 CAN devices were connected over trunk lines varying from 5 to 250 meters • Devices were configured to generate bus traffic as high as 20% bandwidth utilization to simulate worst-case conditions. • A CAN network analyzer was connected to monitor traffic and detect errors • TEST RESULTS: • After over 72 hours of operation, a total of 87 million messages had been sent with only two CAN error frames. This is well within normal expectations for a CAN bus. • CONCLUSION: (tentative) • It appears that industrial CAN networks are entirely suitable for applications such as NeSSI when used with a properly-designed IS barrier.

  19. Adaptation of Honeywell S1 Series Pressure Sensor to NeSSI design standards. • Current Status: • Sensor Design and SP76 housing qualified • Intrinsically Safe (IS). • CAN controller and transceiver chipsets • identified. • DeviceNet protocol selected and pretested • in selected chipset. • Preliminary CAN IS mode testing done. • First POCA units being built for February • delivery to Dow and ExxonMobil. • Next Steps: • Design and build PCBs incorporating selected sensing and communication chipsets/circuits. • Design and build PCBs into SP76 Housings and qualify full product as IS. • Establish and incorporate DeviceNet connector architecture for NeSSI applications. • Test Assemblies in full DeviceNet network. • Identify DeviceNet IS network restrictions and rules. • Propose establishment of DeviceNet IS Special Interest Group (SIG) to • ODVA (Open DeviceNet Vendors Association).

  27. NeSSI Benefits, Nominal Ethylene Plant • Output: 1-2 billion pounds ethylene / year. • Savings enabled by smart, modular sampling (NeSSI I-III): • 430$k/y due to building and ownership cost savings, over 15 year life, of 2.4 and 4$M, respectively (per P.VanVuuren et al) • 100K$/y to 2+M$/y plant operational savings, due to conservative assumption of only a 1% improvement in process control (afford more measurements, and achieve greater efficiencies, less waste and less down time) • Significance: • 1-2% total savings by processing industries • Total US energy use & GDP: 1017 Btu/year & $1013/year • Assume US Process Industry uses 10% of total • NeSSI: 1-2% of 1016 Btu/y (0.1-0.2 quads/y) or $10-20B/y.

  28. NeSSI-II Network and Sensor Developments • CONCLUSIONS • Loaded CAN bus network error rate of 2: 87,000,000 is smaller than expected • Sensors compatible with NeSSI-II are around the corner: PT, FT, • IS certifications of P, F sensors were obtained before and need to be renewed • NeSSI-compatible microanalyzers are under development • Energy and cost savings are projected to be significant: 10-20 B$/y after NeSSI saturation of all industrial processes • Team approach enhances risk of success
