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 Refresher: Why Bother with a Standards At All?

SwagelokCircorParker A good example of a standard that achieves the objectives Refresher: The Current Standard

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

Implementation of the clocking pin on an optional basis allows manufacturers to minimize the cost Reaffirmation of the Current Standard 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.

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

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

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

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

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

SP76.51 Standard Committee Expanded Charter 1.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 Microanalytical devices yet to be developed may add a whole new dimension of creative flow passage access

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

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

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

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 SP76.51 Standard Committee Expanded Charter

Such information forms the basis for building a self- describing system

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 CIA (CAN in Automation) ANSI-ISA SP76.51 Fieldbus Standards Agency Hosting Communication Profile SP76.51 Standard Committee Expanded Charter

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

Summary Becomes the building block for a self describing system!
