OpcUaVariableDescription (STRUCT)¶

TYPE OpcUaVariableDescription : STRUCT

InOut:

Name	Type	Comment
`bValueAvailable`	`OpcUa_Boolean`	Flag if the value is set or not: If this value is OpcUa_True the read operation will be done by the server. This is useful for static values. Write access will be denied. If this value is OpcUa_False the OPC UA Server will call OpcUaProviderRead of the provider that has added this node. OpcUaProviderWrite to write this node.
`value`	`OpcUa_Variant`	[m]: Static value of the node.
`dataType`	`OpcUa_NodeId`	[m]: NodeID of the data type node.
`i32ValueRank`	`OpcUa_Int32`	[m]: ValueRank of the value.
`accessLevel`	`OpcUa_Byte`	[m]: Access level of the node. If bValueAvailable == OpcUa_True this will be changed to CurrentRead.
`useraccesslevel`	`OpcUa_Byte`	[m]: Access level of the node with user rights taken into account. If pszObject is set the CmpUserMgr will be called to get the rights.
`historizing`	`OpcUa_Boolean`	[m]: Flag if historicity is available. By now not supported by the OPC UA server.
`bArrayDimensionSet`	`OpcUa_Boolean`	Flag if the array dimension is set.
`arrayDimensions`	`OpcUa_Variant`	[o]: Description of the array dimensions. Mandatory if the ValueRank is not Scalar.
`bMinimumSamplingIntervalSet`	`OpcUa_Boolean`	Flag if the minimum sampling interval is set.
`minimumSamplingInterval`	`OpcUa_Double`	[o]: Minimum sampling interval of this node.
`bAccessLevelExSet`	`OpcUa_Boolean`	Flag if AccessLevelEx is set
`ui32AccessLevelEx`	`OpcUa_UInt32`	[o]: Extended access level.
