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?
DD-IDE and SDC-625 The HART Standard
HART COMMUNICATION FOUNDATION
Does your computer run MS-Windows 3.11?

DDL Started with HART
Brief DDL History
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.

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 HMI Data Model Communications HART COMMUNICATION FOUNDATION

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
Field Communicator 375-FC
HART COMMUNICATION FOUNDATION
EDDL is the right dividing line between Field Device and EDD Application developers

DDL is the HART Standard
DD
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
Write it Once Test It Once Use It Anywhere
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 HART COMMUNICATION FOUNDATION

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 HART COMMUNICATION FOUNDATION

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 HART COMMUNICATION FOUNDATION
Page 14 of zzzz Copyright - HART Communication Foundation, 2006
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
