DEXPI Specification 2.0.1

This is a bugfix release for DEXPI Specification 2.0.0.

Model Changes

• Core Model

  • modified: enumeration Core.PhysicalQuantities.RatioUnit renamed from PercentageUnit; several literals added

• Plant Model

  • added: concrete class Plant.Instrumentation.ProcessSafetyFunction, subclass of Plant.Instrumentation.ProcessInstrumentationFunction

  • moved: composition property Plant.ProcessEquipment.Heater.TubeBundle, moved from subclass Plant.ProcessEquipment.ElectricHeater to Plant.ProcessEquipment.Heater

  • modified: opposite upper multiplicities of properties Plant.Piping.PipingConnection.SourceItem, Plant.Piping.PipingConnection.TargetItem, Plant.Piping.PipingNetworkSegment.SourceItem, and Plant.Piping.PipingNetworkSegment.TargetItem are now all unlimited (were 1 before)

  • fixed: RDL references for Plant.PlantStructure.IndustrialComplex and Plant.PlantStructure.PlantSection

• Process Model

  • added: composition property Process.Process.InstrumentationActivity.InformationPorts

  • renamed: composition property Process.Process.Composition.MoleFractions, renamed from MoleFractiona

  • removed: enumeration Process.Enumerations.CompositionBasis

  • modified: Process.Process.MaterialStateType.Composition now composition property with multiplicity 0..1, was reference property with multiplicity 1

  • removed: composition property Process.ProcessModel.Compositions

  • removed: composition property Process.ProcessModel.MaterialStateTypes

  • modified: Process.Process.MaterialState.Phases now composition property, was reference property; also renamed from Phase

  • modified: Process.Process.MaterialState.State now composition property, was reference property

  • modified: Process.Process.SeparatingByFlash now subclass of Process.Process.SeparatingByThermalProcess, was (direct) subclass of Process.Process.Separating

  • modified: Process.Process.MeasuringProcessVariable.MeasuredVariable now data property with type Builtin.Undefined | Process.Enumerations.MeasuredQuantity, was composition property with type Core.QualifiedValue

  • added: class Process.Process.SelectingProcessVariable

  • added: enumeration Process.Enumerations.SelectorType

  • modified: composition property Process.Process.StoringEnergy.ChargeCapacity renamed from Capacity

  • modified: class Process.Process.StoringEnergy: description changed

  • modified: composition property Process.Process.StoringEnergy.ChargeCapacity renamed from Capacity

  • added: class Process.Process.StoringMechanicalEnergy

  • added: class Process.Process.SupplyingEnergy

  • modified: Process.Process.SupplyingElectricalEnergy now subclass of Process.Process.SupplyingEnergy, was (direct) subclass of Process.Process.ProcessStep

  • modified: Process.Process.SupplyingMechanicalEnergy now subclass of Process.Process.SupplyingEnergy, was (direct) subclass of Process.Process.ProcessStep

  • added: class Process.Process.SupplyingMaterial

  • modified: Process.Process.SupplyingFluids now subclass of Process.Process.SupplyingMaterial, was (direct) subclass of Process.Process.ProcessStep; properties removed as they are now inherited

  • modified: Process.Process.SupplyingSolids now subclass of Process.Process.SupplyingMaterial, was (direct) subclass of Process.Process.ProcessStep; properties removed as they are now inherited

  • added: class Process.Process.TransportingEnergy

  • modified: Process.Process.TransportingElectricalEnergy now subclass of Process.Process.TransportingEnergy, was (direct) subclass of Process.Process.ProcessStep

  • modified: Capacity moved from Process.Process.TransportingElectricalEnergy to Process.Process.TransportingEnergy.Capacity

  • added: class Process.Process.TransportingMechanicalEnergy

  • added: class Process.Process.TransportingThermalEnergy

  • added: class Process.Process.TransportingMaterial

  • modified: Process.Process.TransportingFluids now subclass of Process.Process.TransportingMaterial, was (direct) subclass of Process.Process.ProcessStep; property Flow removed as it is now inherited from the superclass

  • modified: Process.Process.TransportingSolids now subclass of Process.Process.TransportingMaterial, was (direct) subclass of Process.Process.ProcessStep; property Flow removed as it is now inherited from the superclass

  • added: class Process.Diagram.PortNodePosition

  • added: property Process.Process.ProcessStepDetail.Ports

Reference P&ID

• DEXPI Reference P&ID: types of general Plant.ProcessEquipment.Nozzle items refined to adequate subclasses Plant.ProcessEquipment.AccessNozzle, Plant.ProcessEquipment.InstrumentNozzle, and Plant.ProcessEquipment.ProcessNozzle

Minor Fixes

• spelling errors fixed in descriptions of Process.Process.CalculatingSplitRange, Process.Process.InformationPort, Process.Process.MaterialPort, Process.Process.SeparatingByCentrifugalForce, and Process.Process.ShuttingOffFlow
