OPC Studio User's Guide and Reference
UAAttributeField Constructor(UAAttributeField)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA Namespace > UAAttributeField Class > UAAttributeField Constructor : UAAttributeField Constructor(UAAttributeField)
An object that specifies the node in the OPC server.

Because the UAAttributeField has an implicit conversion from OpcLabs.EasyOpc.UA.Filtering.UASimpleAttributeOperand, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.EasyOpc.UA.Filtering.UASimpleAttributeOperand in place of this parameter, and the corresponding OPC UA attribute field will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromUASimpleAttributeOperand static method instead.

The value of this parameter cannot be null (Nothing in Visual Basic).

Initializes a new copy of the object.
