“We were looking for a SCADA system that would be easy to connect to our ERP application and we also wanted to implement the ISA-95 standard. The Wonderware System Platform met our expectations.”

A Major Project – Standardizing Terminology

TodeploytheWonderwareSystemPlatform,theChevronOroniteGonfrevilleindustrialITteambeganbybecomingfamiliarwiththeISA-95standard.

Thestandardconsistsofterminologyandmodelsthatdescribeboththestructural(products,materials,productionfacilities,andhumanresources)andoperational(capability,production)aspectsoftheproductionsystemsusedtosupportinformationsharing.Italsodefinesdataattributesandstructures,productionoperationmanagementmodels,andtransactionsbetweenmanagementandtheshopfloor.

“Itiswell-structuredanddetailed,butaswithmanynewstandards,ittakesamajorefforttoabsorbitall.Tobetterunderstandit,andto‘pickout’whatwasmostsuitableforoursituation,ourteamattendedatwo-daytrainingsessiononsitegivenbytheControlChainGroup(CGC).Thishelpwasveryvaluabletous,”saidTalleux.ImplementingtheISA-95standardinvolvedamajorefforttostandardizeinternalterminology.Asisoftenthecaseonmanufacturingsiteswith

Objects and Thin Client Workstations - A Bonus for the SCADA System

InchoosingtheWonderwareSystemPlatform,thesimpleconnectionwiththeSAPERPapplicationwasnottheonlybasisforthedecision.Beingabletoworkwiththinclientswasalsooneofthecriteria.Inparticular,thisenabledChevronOronitetomaintainacertainconsistencybetweentheirtwosystems.

Toaccessinformationonthesupervisoryserversinstalleduptothispoint,theGonfrevillesiteisworkingwiththinclients.Thisapproachhastheadvantageofusingmorerobust(nomovingmechanicalparts)andcost-effectiveworkstations,whichdonotrequireupdating.WonderwarealreadyofferedthisoptionwithWindowsworkstations.

“WeweredelightedthatthecompanyexpandedthisoptionandthatwecannowuseLinuxworkstations.Intermsofupdatefrequencyandanticipatedcomputersecurity,wewillhavealotlesswork,”saidTalleux.

RedundancywasalsoastrongargumentforchoosingtheWonderwareSystemPlatform.Toensurehighdataavailability,thedataacquisitionsystemnativelyintegratesaredundancyfeatureusingsimpleconfiguration,whichmeansthatsomeapplicationscanbeputononeserverandothersonasecondserver.Ifoneoftheserversfails,theapplicationsonthefailedserverareautomaticallytransferredtothesecondserver.
