Property Value

The default value of this property is False.

Remarks

Many servers fail in this respect, providing 0 instead of 1 for data monitored items with default queue size.

In order to obtain or modify this parameter, in the default state (when $(memberUrl equals to false), access OpcLabs.EasyOpc.UA.Engine.UAClientAdaptableParameters.MonitoredItemParameters property of static $(memberUrl. If you have set $(memberUrl to true, you need to access OpcLabs.EasyOpc.UA.Engine.UAClientAdaptableParameters.MonitoredItemParameters property of $(memberUrl.

This member or type is for use from COM. It is not meant to be used from .NET or Python. Refer to the corresponding .NET member or type instead, if you are developing in .NET or Python.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.

Requirements

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