technology• Promote the concept of...

– at the pipe/field-mounted (“byline”) analytical systems

• Lay the groundwork for...– open connectivity communication architecture

• Provide a technology bridge to the process for...– “sensor/lab-on-a-chip” microanalytical devices

• Reduce Cost to Build– Design and Engineering– Manufacturing and Installation

• Reduce Cost of Ownership– Design Standardization– Simpler, less expensive maintenance

• Enhance Reliability– Validate sample, data, communication

• Do you have any questions regarding the the standard footprint and/or the relevance of your technology to this concept and/or its suitability beyond plant applications (lab, pilot plant, etc)?

• Do you understand the Process Safety issues and requirements (e.g. I.S. Ex ia)? Would your like to discuss any of them?

• Foundation like organization?• Applet creator?• Analyzer Vendors?

• Would you agree that SAM would be useful device for interfacing and interacting with both the Sensor bus and the larger world of the Ethernet – What do you (or don’t you) like….?– What would you like improved or added?
