Progress Ø Ø In addition, preparations are being made to test power supply schemes for low powered CAN Bus as per the Ci. A (CAN in Automation) Intrinsically Safe CAN Bus Working Group Working network of sensors, valves, and control devices will be online in late Feb according to proposed IS power supply and communication scheme CIRCOR Tech Core sensing and control modules will have different bus flavors available according to end user or analyzer OEM preference (I 2 C, CAN Bus, Modbus, RS 485) Will be working with CAN and other PLC and/or hybrid controller companies to bring control solutions for retrofit activity outside of smart GC’s Complete, Modular, Ready Today www. circortech. com

What’s Next? Ø Mainstream customers will not adopt a “discontinuous” technology without: § Having the “whole product concept” fulfilled ü Having the entire core product (s) augmented by EVERYTHING that is needed for the customer to have a compelling reason to buy ü Distributors or sales people skilled in the new technology ü Good warranty, strong company, and strong support ü 2 nd Sources and a Competitive Marketplace § This includes the product (s) along with training, support, manuals, cables, connectors, accessories, additional hardware and software, etc. § Example: One cannot implement an IS CAN Bus solution without a certified IS Power Supply, an IS CAN Bus Isolator Repeater, Special Cabling, Wiring Documentation, and Config.

What’s Next? Being developed ØExample of IS CAN Bus Network (courtesy of Ci. A IS CAN Bus working group Needs further development and certifications Being developed Complete, Modular, Ready Today www. circortech. com

What’s Next? Ø What is still needed to fulfill the Whole Product Concept for Digital Bus? § More power supply components § Repeaters, Isolators, and Barriers § Connectors and Cabling § Configuration Management Software § A Standalone SAM (Sensor Actuator Manager) for non-GC analyzer applications with HMI Ø What is needed for overall Ne. SSi system success? § End users must “change behavior” in order to adopt a discontinuous technology innovation § At a certain point, innovation must cease to allow customer to digest what is currently being offered. Otherwise, they are waiting on the next revision Complete, Modular, Ready Today www. circortech. com

What’s Next? Ø Examples of what to expect § Digital bus system maintenance will require software and hardware interaction between analyzer and sample system § Could get stuck in information overload mode if streaming data is provided rather than mission critical decision making information § Sample system purge systems go away, potentially exposing the digital devices to concentrated chemical vapors continuously § Compromises may have to be made to make digital bus sensors cost effective in these extreme environments ü ü ü IP 65 ratings a necessity, corrosive resistance a must, 85 deg C operation Hot Swap, Plug and play, C 1 D 1, Zone 1 (possibly Zone 0) certifications become necessary Digital devices must be field addressable rather than “software addressable” which means that windows, access ports, must be available Some sort of visual indication of system health would be desirable rather than going back and forth between SHS and analyzer CAN IT ALL BE ACHIEVED COST EFFECTIVELY? ? ?

What’s Next? Ø Examples of what to expect, cont. § Energy budgets will become important due to the relatively high cost § § per milliwatt of special IS power supplies Terms like “average cost per node”, and “average power per node”, will used to as a technical selling advantages for smart digitally controlled sample systems Multi-function, multi-variable devices will be leveraged to gather multiple pieces of information with a single bus node, minimizing connection cost Digital bus node functionality and failure modes (FMEA) will have to be taken into account when performing system design and safety reviews of smart sample systems Will integrators adopt this responsibility quickly?
