Tools(2),Typical Use Cases:Workshops or small installationsOnline connection to the deviceOperation mainly via the DTMs GUIUser has access to all DTM functionality,e.g.by switching between different tab cardsCurrent configuration and parameters are read from the deviceParameters may be written to the device e.g.for test purposes,FDT Technology Overview The Complex Case:Control Systems(1),Asset Management,Engineering Tool,HMI,Automation,Field Device,DiagnosisCalibrationMaintenance,ConfigurationParameterization Commissioning,OperatingAlarm reportingMonitoring,Process variablesClock synchronizationStatus,FDT Technology Overview The Complex Case:Control Systems(2),Typical Use Cases:Different Frame Applications may use a DTM in different contexts Availability of DTM functions is controlled according to the application contextAll settings loaded to the device are stored in a system databaseOnline connection to the device is not always available DTM works on database onlyDTM functions are frequently used in the background w/o starting a user dialog,FDT Technology Overview Communication,Profibus DPV1 Read RequestProfibus DPV1 Read Response,FDT Technology Overview Profibus XML Examples,FDT Technology Overview Nested Communication,0.20 mA,HART,Ethernet,Ethernet based Protocol,FDT Technology OverviewCommunication uses Tunneling,Ethernet,TCP/IP,FDT Technology OverviewCommunication,Each component wraps the communication frame from the component below,WITHOUT knowing the contentsRouting through system topologyDTM below does not have any knowledge about the network topologyDTM must only support its own communication protocolCommunication/routing through ANY network topology,no limitationsCommunication/routing is possible even if the underlying protocol is unknown by the engineering or standalone tool,FDT Technology Overview Scope of FDT Core Specification,Software Architecture(Components,Interfaces)DeviceDTM,CommDTM,FDT Container COM Interfaces and
