MonitoringParameters Property (EasyUASubscriptionChangeArguments)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.OperationModel Namespace > EasyUASubscriptionChangeArguments Class : MonitoringParameters Property
Contains new monitoring parameters (such as the sampling interval, and optional data change filter).
Syntax
'Declaration
 
Public Property MonitoringParameters As UAMonitoringParameters
'Usage
 
Dim instance As EasyUASubscriptionChangeArguments
Dim value As UAMonitoringParameters
 
instance.MonitoringParameters = value
 
value = instance.MonitoringParameters
public UAMonitoringParameters MonitoringParameters {get; set;}
public:
property UAMonitoringParameters^ MonitoringParameters {
   UAMonitoringParameters^ get();
   void set (    UAMonitoringParameters^ value);
}

Property Value

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

Returns the monitoring parameters object.
Exceptions
ExceptionDescription

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

The getter method of this property is pure, i.e. it does not have observable side effects.

Because the OpcLabs.EasyOpc.UA.UAMonitoringParameters 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 sampling interval in milliseconds) in place of OpcLabs.EasyOpc.UA.UAMonitoringParameters value when setting this property, and the corresponding OPC UA monitoring parameters will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.UAMonitoringParameters.FromInt32 static method 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
