The key to interoperabilityBackground

Time: circa 1990

Situation: valves and transmitters are becoming microprocessor based; intelligent field devices

HART® Communication Protocol is popular

Issue: Interoperability of devices with Host applications

EDDL Tutorial


5

The key to interoperabilitySolving Interoperability …

Problem: How does the Host understand device capabilities and interpret digital information in the HART messages?

Option #1: Custom Software Drivers

Software driver needed for each device type

Time consuming/costly to write

Difficult for supplier to maintain

Difficult for end users to manage

EDDL Tutorial

The key to interoperabilitySolving Interoperability …

Problem: How does the Host understand device capabilities and interpret digital information in the HART messages?

Option #2: Use a Descriptive Technology

EDDL Tutorial

The key to interoperability The key to interoperability

What is EDDL?International Standard for Interoperability

EDDL is an Electronic Device Description Language

EDDL is an international standard

Endorsed by IEC (IEC 61804)

EDDL is endorsed by the three major digital busses

Fieldbus Foundation

HART Communication Foundation

Profibus Nutzerorganisation e.V (PNO)

EDDL Tutorial

The key to interoperabilityEDDL

EDDL technology was designed to avoid the need for special, proprietary, and operating system-specific host application files

It allows a host system to both configure as well as monitor devices on-line

Consists of two parts

A file (EDD) that describes the device and the information that it contains

A host application that reads the EDD file to learn how to retrieve and interpret digital information from the device

EDDL Tutorial

The key to interoperability The key to interoperabilityWhat is an EDD?

An EDD is the computer readable file written in Electronic Device Description Language (EDDL) that describes the data in a field device

It is in a compressed binary formatIt is not executable code

It is the file that the Host application reads in order to learn how to retrieve information from the field device

EDDL Tutorial

The key to interoperability The key to interoperabilityEDD’s and Interoperability

EDD’s enable :- Devices from different suppliers to interoperate with a single Host

- The same device to interoperate with different Hosts.Device fromSupplier A

Device fromSupplier Z

Describes How the device functions per IEC 61804 Small ASCII files (< 200k)

The key to interoperabilityBackground

Time: Circa 2002

Situation: Fieldbus Foundation, HART Communication Foundation and Profibus are all using EDDL

Valves and transmitters are becoming more intelligent

Field devices are incorporating complex diagnostics and set-up requirements

Issue: EDDL in IEC 61804-2 does not have any features to support graphical display of diagnostics and advanced device features

EDDL Tutorial


13

The key to interoperabilityEDDL Has Been Enhanced

Goal: Extend Interoperability to support increasing device intelligence

The HART Communication Foundation, the Fieldbus Foundation and Profibus Nutzerorganisation e.V formed a Cooperative Project to specify EDDL enhancements

The enhancements have been tested and have been added to IEC 61804

Approved on 10 Feb 2006

The new document will be published as IEC 61804-3, in June 2006

Benefits to End Users and Vendors


19


Independency of EDDL –is minimizing continuous upgrades

EDDL / EDDs are independent from Operating systems and versions DCS platforms Communication interfaces and paths

Why? EDDs are text based files There is no executable code in an EDD EDDs are managed by an interpreter, all communication setups

are done by the DCS or the tool EDD and Excel sheets – a comparable technology

Both describe user interfaces including graphics and complex relations between the data

In case of changing the versions of EXCEL or the operating system there is no need to upgrade the sheet It simple works!



20


EDDL is Easy to Use ensures transparency and accessibility in your plant

Build in state of the art graphics

Trends, Bar graphs

One tool for all devices

Common transparent data base

A new device just a new EDD

Same Look & Feel in a tool / DCS for all devices

EDDs define the data organization for the UI to build up a real one



21


EDDL Technology Supports Safe Operation of Your Plant

No influence on the runtime stability

There is no executable code with EDDs which may have an effect to the stability of the operating system

EDDs are interpreted and therefore encapsulated

No impact of one EDD to others

Easy update and device additions during operation

Interpreter

22


EDDL – For Vendors: Easy to Use and to Learn, Easy to Maintain

EDDL is easy to learn

Like Visual Basic

Standard text editor

Context sensitive editors available

Existing EDDs can be used as a basis for a new device

Learning by doing

One EDDL – many languages for localisation

VARIABLE tag

{

LABEL “TAG“;

HELP “|en|Text that can be used in any way.“

CLASSDEVICE;

TYPE INTEGER(1)

}

Definition of a variable of a device


Adapting an EDD to a new device version

normally means copy/paste and small adjustments


23


EDDL - Backbone for Diagnostics & Maintenance Management System

EDDs provide diagnostics data for Maintenance Management Systems

Occurrences of non regular states of components are signaled to an DCS

The diagnostics data are read via the corresponding EDD from the device w/o disturbing the plant operation

Predictive maintenance based on EDDs saves costs due to reduced cyclic scheduled service tasks



24


EDDL Keeps Your Investment Alive

Reduced costs for education and training

Learn handling once- manage all devices and components due to the common Look & Feel in your Tool or system

Transparent backward compatibility reduces upgrade costs in case of

Operation System upgrade

Tool / DCS upgrade

Stable and consistent EDDL standard reduce costs

no upgrades of EDDs due to new EDDL version at a device supplier

No installation of such “new” (means upgraded) EDDs at end users



25


EDDL – Fits Best in All Environments

EDDL is used

from Handheld

from simple devices

to very complex devices1) Manufacturing Execution

EDDL and OPC UA


29

The key to interoperabilityOPC Foundation

International Industry Standard Organization

400+ Member Companies / 40+ end-users Members

2500+ Total Companies Build OPC Products = 15000+ Products

The vision of OPC is to be the Foundation for interOperability

for moving information vertically from the factory floor through the enterprise of multi-vendor systems (with stops in between…)

For moving information horizontally between devices on different industrial networks from different vendors;

Not just data but information…….

Reliable, Secure Integration is a must

Collaboration is key to pulling multiple “open” standards into unified open platform architecture….

Why OPC and EDDL

OPC UA - A single interface standard

Based on Web-Services (internet-technology) Allows solutions to run different operating systems (OS Independence)

Consolidates existing OPC interfaces (data, archive, alarm, event)

EDDL information (Parameterization, etc) in addition to data type is provided by an OPC

UA server, which enables client application to use OPC UA server data with reduced engineering effort
