Property filled when Elipse E3 connects to an OPC UA Server, which indicates the data type on that OPC UA Server. This property is initially filled during the browsing process, if performed, and in any communication or connection to an OPC UA Server. Values below 1,000 are scalar and values above 1,000 are arrays. This is a read-only property. Possible values for this property are described on the next table.

•Structures defined by specific OPC UA Servers, not compatible with the OPC UA standard, are not read by Elipse E3. •Data types udtArrayQualifiedName, udtArrayLocalizedText, udtStructure, udtArrayStructure, udtArrayDataValue, and udtArrayUnknown do not allow writing in the current version of Elipse E3, because Elipse E3 uses a simplified formatting of these data types. •Data types ServiceCounterDataType (array with two positions), BuildIndfo (array with six positions), Argument (array with six positions), ApplicationDescription (array with eight positions), SessionDiagnosticsDataType (array with 44 positions), SessionSecurityDiagnosticsDataType (array with 10 positions), SubscriptionsDiagnosticsDataType (array with 31 positions), ServerDiagnosticsSummaryDataType (array with 12 positions), ServerStatusDataType (array with six positions), EuInformation (array with four positions), Range (array with two positions), TimeZoneDataType (array with two positions), DiagnosticInfo (array with seven positions), StatusResult (array with two positions), ComplexNumberType (array with two positions), DoubleComplexNumberType (array with two positions), XVType (array with two positions), RedundanteServerSataType (array with three positions), SamplingIntervalDiagnosticsDataType (array with four positions), EnumValueType (array with three positions), EndpointUrlListDataType (array with two positions), and NetworkGroupDataType (array with three positions) are displayed as udtStructure, but Elipse E3 handles the specific data type. •In the current version, Elipse E3 only allows single-dimension arrays, that is, it does not allow matrices as data types. |
