CHAPTER1 INTRODUCTION

CONTROLSYSTEMSTUDIO

The Control System Studio (CSS) is an Eclipse RCP based development platform and thefundamentformanyapplicationslikeEPICS,TANGOetc.Asmostoftheseapplicationsdealwithprocessvariablesandconnectionstocontrolsystems,theCSSCoreprovidesthenecessaryAPIsforaconvenientstart.

The integrated development environment of CSS provides facility for database development,alarmmanagementsystem,displaydevelopmentandconversion,datatrending,diagnostictoolsetc.

The Data Access Layer (DAL) is the core of the connection APIs. It communicates to EPICSthroughCAJ(ChannelAccessJava),whichisapureJavaimplementationoftheCAprotocol.Inthe (near) future itwillbepossible toconnect to TINEandTANGOcontrol systems throughDALaswell.ATINEintegrationisalreadyavailableasBeta.DALisaninherentpartoftheCSSCorebutcanalsobeusedasalibraryinanyotherJavaapplication.SimpleDALisaconnectionlayerbuiltontopofDAL.Itprovidesaslim,lesscomplexAPIthatallowsforamucheasierstartfordevelopersdealingwithprocessvariables intheirapplications.UsingSimpleDALimpliesacertain syntax for process variable addresses that enables applications to make use of thefollowingfeatures:

•Accessdifferentcontrolsystems(e.g.TINEandEPICS)inoneapplication

•usecharacteristics,aconceptforresourcesavingaccesstorecordfields

•queryprocessvariablesindifferenttypes

•usesimulatedchannels

•addresssystemfunctionsasprocessvariable
