OPC Studio User's Guide and Reference
PutProperty Method



OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc.DataAccess.Extensions Namespace > DAItemPropertyRecord Class : PutProperty Method
The Id of OPC property to be modified.

Because the OpcLabs.EasyOpc.DataAccess.DAPropertyId has an implicit conversion from System.Int64 and OpcLabs.EasyOpc.DataAccess.DAPropertyIds, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a long integer (representing the numerical value of the access rights), or an element of the OpcLabs.EasyOpc.DataAccess.DAPropertyIds enumeration in place of this parameter, and the corresponding Property Id specification will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the DAPropertyId Constructor(Int64) or DAPropertyId Constructor(DAPropertyIds) constructor instead.

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

The new value of OPC property.

The value of this parameter can be null (Nothing in Visual Basic).

Modified a property value in this structure, for an OPC property specified by its Id.
