Rosemount 1151S At HART Foundation >12 Years

– In Foundation Office When I Joined !– Device Revision 5(Not the newest revision of 1151S)

Its EDD was Written 1993/*

* 1151SII Rev 5 HART Device Description * * HART Communicator Toolkit rev G * * Garrie Huisenga 6/3/93 * Updated 10/14 by Chip Rauth to add 2nd precision tables, * changed g formats to e formats * DD rev 2 to use RMTPRES5 and more like 3051C

*/

Rosemount Still Ships 1151s– Millions in Plants*

(* according to Rosemount Website)

– Customers Require Support



The 1151S' EDD Today

Exactly Same EDD– Still Works – Devices in Plants

Still Supported– 13 Year Old DD

Where are the people who wrote this EDD?

On old devices, who updates the EDD so it works today?

DDL Started with HART

1990 "International Fieldbus Group" Notion of DDL

1991-1993 DDL and HC-275 presented at HUG 1994 HCF DD Library established for

registration and distribution 1994 First HCF DD Workshop 1995 Large HC-275 shipments begin 1996 FF Adopts DDL 2001 DDL IDE project initiated

– Enhance DD Developer Productivity– Access to DDL Technology by all HART members

2003 EDDL Cooperation Group Starts 2004 EDDL Approved by IEC 2004 DD-IDE & SDC-625 Released 2004 Honeywell FDCM & handheld released

– First SDC-625 based host. 2005 HCF SDC-625 Supports 100% of EDDL Enhancements 2005 New HART DDL Specifications Approved 2006 EDDL with Enhancements Approved by IEC ** Actually HCSIMActually HCSIM

Brief DDL History



Elements of an EDD Data Modeling

– Fundamental EDDL Capability– Models Field Device Real-Time Database

Smart Field Device like RTU in SCADA– Other EDD Declarations Refer to Data Model

Communications– Defines all communications capabilities– EDD Application Chooses What and When to

Communicate HMI

– Allows a User to Browse Field Device– EDD Developer Determines Organization

and Content– Host Application Determine Look and Feel

Methods– Models Standard Operating Procedures (SOPs)– Ensures User Performs Procedure Consistently

EDDL Technology No Other Programming Language

Like EDDL

An EDD is a Text-Based Model of the Field Device

– Developers Describes What Capabilities are in their Field Device

– NOT How the Application should use the Field Device

– Supports Simple to Complex

Host Application Interprets the EDD– Developer focuses on the

EDD Application– Provides a secure "window" to

browse the Field Device– EDD describes the Application's

view of Field Device using MENU

EDDL is the right dividing line between Field Device and EDD Application developers

EDD's are Portable Operating Systems

– Unix (Solaris)– Windows NT, 2000, XP (SDC-625,

PDM, AMS, FDM, etc.)– Embedded (HC-275, 375-FC)

Processors– ARM– Wintel– Motorola 68302

Protocols– HART– PROFIBUS– FOUNDATION FIELDBUS

– Others

HART EDDL Today HCF DD Library

– >60MBytes of Encoded EDDs– 1079 DDs, 438 devices, 100 manufacturers– 3.6 Million Lines of Code– Adding 150 EDD's per Year– Stable and field-proven for long life

Continuing Investment in EDDL Technology– Enhancements to EDD Language– Tools for EDD Developers,

Host Applications– Continuous Quality Improvement– Industry Education– Simplifying Access to HART EDD Library

EDDL is the Only Technology Endorsed by the HCF for the Configuration of HART Devices

EDDL is the Only Technology Endorsed by the HCF for the Configuration of HART Devices



One Encoded EDD works on all Hosts– The real promise of EDDL– Real EDD portability– Lower host and field device development costs– Provide end user access to DD's

Critical DD Development Tools controlled by HCF– DD-IDE Tool Suite and SDC625 reference Host– Managed and maintained as HCF standards

SDC625 (HCF Interpreter) licensed by HCF members for inclusion in commercial products– Ensures correct interpretation of DDs and full benefit of testing,

validation and registration process

EDDL Quality Assurance HART DD Library Registration Key to EDD QA

All EDDs must registered and verified with reference Host(source files archived, symbols controlled)– Well defined process for Registering EDDs– Detailed, Repeatable process to ensure Consistency, Quality– Process updated as loop-holes identified

All EDDs distributed as single encoded file to ensure security and integrity – this file must work on all EDD compliant Hosts

Evolving, improving since 1994



Backward Compatibility A Core HART Value

– HART Specifications detail how a revision is made to a field device – You can replace an old device with a new one without changing the host

application.» New Revisions work in place of old revisions.

– You can Add to a device (Commands, Data)– You can't change what's already in the device

Backward Compatibility in EDDs: – Compliance detected by auditing symbols

» Symbol = Name of Data, Command, Menu, etc» Symbol changes, additions, deletions detects

– No Changes to EDDL that break an Existing EDD.– All Hosts must support registered EDDs



Continuous Quality Improvement Big Need to start testing host applications

EDDL Interoperability Guidelines – Basic host interoperability – Documents Enhancements

EDDL Common Test Requirements– Identify test requirements common to all Protocols– Focus on Host Requirements First

HART EDDL Working Group– Addressing HART-Specific Requirements– Beginning work on actual test program

HART Interoperability Workshops– Held twice a year– Sharing between host and EDD developers– Everyone in one room.



The EDDL Enhancements – The Evolution Continues

Growing acceptance of DDL and increasing complexity of devices created the need for improved user display

Enhanced DDL extends capabilities to support graphical Windows display of device information– + Graphic objects, charts, trends– + Storage of device data in Hosts – + Increased computation for managing complex devices

International Standard - IEC 61804, EDDL

EDDL Cooperation Team (ECT) established by HART, PNO, FF and OPC to further the technology and maintain IEC Standard



First Enhanced DD Registered at HCF Enhanced DDL marks a significant change

– Applications can now maximize the full capability of intelligent field devices

– Reduces the need for custom device configuration and diagnostic software

Configuration and monitoring is now easier and faster– Reduces errors and downtime

An International Standard - IEC 61804, EDDL

Built on experience, designed by experts

EDDL Technology – Safe, Secure and Robust
