Presentation Transcript

  1. SP76.51 Symbol Library:“The NeSSI Component Info-Net™” Steve Doe, Parker Hannifin

  2. Topics • ANSI/ISA-76.00.02-2002 Refresher & Reaffirmation • SP76.51 Origin & Charter • Expanded Charter- “Component InfoNet™” • Port Designators • Communications Appendix

  3. Refresher: Why Bother with a Standards At All? • Provide an agreed-upon, understandable & accessible information database that benefits an industry-wide base of users & suppliers (SHS stakeholders) • Leave room beyond the agreed-upon elements of the standard for manufacturers to compete in the marketplace

  4. Refresher: The Current Standard A good example of a standard that achieves the objectives Swagelok Circor Parker

  5. Experience has taught us that perhaps the much-debated alignment pin was a good idea Reaffirmation of the Current Standard • ANSI/ISA reaffirmation of the Standard is due in 2007 • Parker proposes inclusion of the clocking pin as an option into the reaffirmed standard

  6. Reaffirmation of the Current Standard Implementation of the clocking pin on an optional basis allows manufacturers to minimize the cost Provides a fail-safe method to insure proper field orientation of an operational device to its associated substrate flow path Improper field orientation of operational devices can have detrimental effects on a system's functionality, with potentially hazardous results.

  7. SP76.51 Standards Committee Origin • Supplement to the existingISA-5.1-1085(R1992) to an all-inclusive library of symbols for devices used specifically in process analytical schematics • Because…

  8. SP76.51 Standards Committee Origin …variety isn’t the spice of life when it comes to schematics!

  9. SP76.51 Standard Committee Current Charter • Library is poised for committee member review and comment • Committee membership is open to any interested stakeholder; contact David Lewko if you’re interested in participating (lewkod@bantrel.com)

  10. SP76.51 Standard Committee Current Charter Each symbol becomes the basis for an agreed upon description of a functional component…

  11. SP76.51 Standard Committee Expanded Charter …and provides a reference point for its physical relationship within a system that can now self-describe

  12. Microanalytical devices yet to be developed may add a whole new dimension of creative flow passage access SP76.51 Standard Committee Expanded Charter • Establish a “porting legend” for all functional devices • SP76 allows device makers to access any combination of the (5) defined flow passages • Simple 2-port devices are intuitive • 3-port devices may not be quite so intuitive

  13. For example, one schematic defining a simple 2-way valve • Three manufacturers’ products Parker Swagelok Circor • Conventional wisdom leads all three manufacturers to define the center port as inlet and offset as outlet SP76.51 Standard Committee Expanded Charter • Providing end users with field plug and play freedom!

  14. SP76.51 Standard Committee Expanded Charter However, what if a competitive performance advantage can be achieved by porting differently? Manufacturer “X”

  15. SP76.51 Standard Committee Expanded Charter Both SP76 Compliant, but is it still “Plug & Play” ? End users are entitled to know how devices within a symbol definition are ported

  16. SP76.51 Standard Committee Expanded Charter • Last committee meeting was held at ISA Expo last October • Attendees agreed in principal to include a “port legend” template to define flow passage requirements for each symbol

  17. SP76.51 Standard Committee Expanded Charter • Such information forms the basis for building a self- describing system

  18. SP76.51 Standard Committee Expanded Charter • The template can also be appended to provide operational and connectivity information relative to networked and non-networked devices, including electrical and flow net listing Standards Agency Hosting Communication Profile CIA (CAN in Automation) ANSI-ISA SP76.51 Fieldbus

  19. Summary • A simple standard symbolic description…

  20. Summary • A simple standard symbolic definition… • Bolstered with a standard template for describing physical & communication connectivity details….

  21. Summary • Becomes the building block for a self describing system!

  22. Thank You! Committee membership is open to any interested stakeholder; contact David Lewko if you’re interested in participating (lewkod@bantrel.com)
