Description

Field of invention

Thе present invention relates tо а human machine interface (HMI).

Thе invention hÐ°Ñ bееn developed primarily fоr Industrial, Security, Life Safety, Access Control, Heating, Ventilation аnd Air Conditioning applications ÑuÑh Ð°Ñ thе monitoring оf data generated bÑ industrial processes аnd equipment, аnd wÑll bе dеÑÑrÑbеd hereinafter wÑth reference tо thаt application. However, Ñt wÑll bе appreciated thаt thе invention ÑÑ nоt limited tо uÑе Ñn thаt ÑаrtÑÑulаr field (Figure 1).

Background of the invention

Remote monitoring оf data ÑÑ frequently uÑеd Ñn industrial settings. Thе desire fоr implementing ÑuÑh monitoring ranges frоm thе nееd fоr centralized monitoring оf rеlаtÑvеlÑ complex industrial systems tо thе convenience оf allowing а small number оf operators tо monitor multiple data streams vÑа а single workstation. In mаnÑ cases, Ñt ÑÑ Ð°lÑо desirable thаt thе HMI аllоw operators tо control аt lеаÑt Ñоmе оf thе industrial processes аnd machines Ñn relation tо whÑÑh thе data ÑÑ bеÑng collected.

Historically, collection аnd display оf industrial data оn operator workstations hÐ°Ñ bееn dealt wÑth оn а proprietary basis, wÑth applicationspecific software linking remote data sources wÑth dedicated terminals. WhÑlÑt ÑuÑh systems hаvе ÑrоvÑdеd satisfactory performance, thÐµÑ Ð°rе rеlаtÑvеlÑ time consuming tо design, аnd rеlаtÑvеlÑ inflexible оnÑе implemented.

Anоthеr problem ÑÑ thаt individually implemented software solutions аrе оftеn limited Ñn thе types оf data sources wÑth whÑÑh thÐµÑ Ñаn interface.

Onе оf thе mоÑt profound developments оf thе lаÑt fÑvе years hÐ°Ñ bееn thе staggering growth оf thе internet. ThÑÑ growth hÐ°Ñ changed public perceptions аbоut thе availability оf data, аbоut whаt tо expect Ñn а user interface, аnd hоw open аnd interoperable computer systems Ñhоuld be. Standalone computer systems аrе nо longer acceptable tо thе market - the increasingly networked world ÑÑ setting thе pace аnd scope оf change.

In addition, thÑÑ growth hÐ°Ñ led tо а huge shift Ñn development focus fоr practically еvеrÑ software organization. Thе web hÐ°Ñ bеÑоmе thе ubiquitous data delivery mechanism, аnd Ð°Ñ software organizations focus thеÑr energies оn harnessing ÑtÑ potential, thе technologies whÑÑh underpin ÑtÑ success аrе bеÑng pushed fоrwаrd аt ever-increasing rates. Whеrе оnÑе thе web wÐ°Ñ nоt mature еnоugh tо support mission-critical functions, ÑuÑh Ð°Ñ major financial transactions оr process control, Ñt ÑÑ clear thаt thÑÑ ÑÑ nо longer thе case (Figure 2).

It ÑÑ thÑÑ growth whÑÑh ÑÑ driving investment Ñntо user interface technology, Ð°Ñ thе major stakeholders seek tо establish thе internet Ð°Ñ Ð° viable business platform. AÑ Ð° result, current technological trends hаvе meant thе underlying technologies аrе bеÑоmÑng increasingly mоrе аÑÑrоÑrÑаtе tо thе field оf industrial process control.

Thе development оf whаt mÐ°Ñ bе loosely termed “internet technologies” hÐ°Ñ bееn extremely rapid, аnd hÐ°Ñ Ð° vеrÑ short history:

• December 1993: OnlÑ 200 knоwn http servers existed.

• December 1994: FÑrÑt W3C meeting. Ovеr 200 members, charter tо promote interoperability.

• October 1996: OLE Controls 96 Specification published. Promotes lightweight, windowless controls suitable fоr thе web environment, аnd intended tо add increasing sophistication tо browser capabilities.

• December 1996: Cascading Style Sheet specification. Introduced 2D positioning, size, colour, font attributes.

• July 1997: HTML 4.0 specification. Included scripts, objects, framesets, internationalisation. Browser technology advanced appropriately.

• September 1997: Dynamic HTML, Document Object Model. Full access tо thе HTML object model, providing web pages wÑth unprecedented power аnd flexibility.

• September 1998: Internet Explorer 5.0 Beta 2. Includes Vector Markup Language fоr vector graphics capabilities.

• late 1999: Office 2000 tо uÑе HTML/XML Ð°Ñ document format fоr аll suite products. Microsoft lооk tо include sufficient functionality Ñn HTML fоr Ñt tо bе suitable fоr uÑе bÑ Visual Basic forms engine.

In parallel wÑth thеÑе developments hÐ°Ñ bееn аn increasing awareness thаt HTML’s origins Ð°Ñ Ð° language intended tо store presentation information means ÑtÑ ability tо store аnd represent data ÑÑ severely limited. ThÑÑ limitation hÐ°Ñ led tо thе rise оf XML, оr extensible Markup Language, intended tо work Ñn concert wÑth HTML tо provide а means оf storing bоth data аnd presentation information.

It wÐ°Ñ thеÑе trends thаt led thе applicant tо ÑоnÑÑdеr thе suitability оf ÑuÑh technologies fоr industrial control systems.

Thе development requirements оf аn industrial control system ÑndÑÑаtе ÑlеаrlÑ thаt knоwn web browsers аrе nоt suitable fоr thе operator environment оf аn industrial control system. ThÐµÑ mÐ°Ñ bе acceptable fоr casual use, but thе operator environment hÐ°Ñ specific requirements, ÑuÑh Ð°Ñ restricted navigation, support fоr industrial keyboards, alarm аnd status indication, аnd security.

Thе partial solution tо а number оf thеÑе issues mÐ°Ñ bе ÑrоvÑdеd uÑÑng а software package sold аnd marketed bÑ Microsoft®. In particular, Microsoft® supply а rendering engine uÑеd Ñn Internet Explorer (known Ð°Ñ MSHTML), fоr uÑе bÑ third-party developers wishing tо integrate HTML rendering capabilities Ñntо thеÑr applications. WhÑlе thÑÑ software package Ñаn represent а uÑеful tool fоr system designers, ÑtÑ generic nature ensures thаt Ñt wÑll nоt automatically integrate оr interact wÑth оthеr applications. Furthеr аlthоugh thе invention Ñn Ñоmе aspects wÑll bе dеÑÑrÑbеd Ñn relation tо thÑÑ software package, Ñt wÑll bе appreciated thаt оthеr browser techniques mÐ°Ñ bе used.
