DAItemPointSubscribeParameters Constructor(DAGroupParameters)



OpcLabs.EasyOpcClassic Assembly > OpcLabs.EasyOpc.DataAccess.Connectivity Namespace > DAItemPointSubscribeParameters Class > DAItemPointSubscribeParameters Constructor : DAItemPointSubscribeParameters Constructor(DAGroupParameters)
The group parameters to use.

Because the OpcLabs.EasyOpc.DataAccess.DAGroupParameters has an implicit conversion from System.Int32, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (representing the requested update rate in milliseconds) in place of this parameter, and the corresponding OPC DA group parameters object will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.DataAccess.DAGroupParameters.DAGroupParameters Constructor(Int32) constructor instead.

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

Creates a new instance of the object, from OpcLabs.EasyOpc.DataAccess.DAGroupParameters.
