EasyUASubscriptionChangeArguments Constructor(Int32,UAMonitoringParameters,UASubscriptionParameters,Boolean)



OpcLabs.EasyOpcUAPrimitives Assembly > OpcLabs.EasyOpc.UA.OperationModel Namespace > EasyUASubscriptionChangeArguments Class > EasyUASubscriptionChangeArguments Constructor : EasyUASubscriptionChangeArguments Constructor(Int32,UAMonitoringParameters,UASubscriptionParameters,Boolean)
Contains handle of the monitored item to be affected.
Contains new monitoring parameters (such as the sampling interval, and optional data change filter). Must not be null.

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 this parameter, 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.

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

Contains new subscription parameters (such as the publishing interval). Must not be null.

Because the OpcLabs.EasyOpc.UA.UASubscriptionParameters 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 publishing interval in milliseconds) in place of this parameter, and the corresponding OPC UA subscription 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.UASubscriptionParameters.FromInt32 static method instead.

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

When set to true, a ConditionRefresh will be automatically performed when needed to keep the condition information up-to-date.
Initializes a new copy of the EasyUASubscriptionChangeArguments object from the monitoring item handle, monitoring parameters, subscription parameters, and auto condition refresh setting.
