SUMMARY

AfterSiemensreleasedthenewerfirmwareV4.0andthereafter,manycustomersreportedtheycannolongergetdataupdateswithWonderwareDASSidirect..

AfterthenewFirmwareV4.xreleasefortheS71500andS71200PLCfamily,manycustomersfoundthemselvesnolongerabletogetdataupdatefromthosenewlyupgradedPLCs.Thereasonwasthatthe

newSiemensPLCfirmwareaddednewfeaturesthatkeepPLCDBfromsharingthedata.InfactnotsharingDBisthedefaultsetting.

AnothernewfeatureinthenewPLCFirmwarereleasesupportssymbolicitemnamingwhereyoucanassigntheplcdatablocksandelementswithmoredescriptivesymbolicnames,andallowtheclient

applicationandinterfacedrivertoaccesstheDBwiththesymbolicnamesasitemnames.

ThisTechNoteprovidestheWonderwareDASSiDirectinformationneededtogetconsistentdataaccessfromtheS71200and1500PLCwiththosenewfeatures.

SITUATION

software.OncethechangesaremadeinthePLC,WonderwareDASSidrectwillbeabletogetdatawithoutanyadditionalconfiguration.
