Property Value

This value of this property can be null (Nothing in Visual Basic).

The default value of this property is null.

Remarks

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 the OpcLabs.EasyOpc.DataAccess.DAGroupParameters value when setting this property, 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.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
