EasyUASubscriptionChangeArguments Constructor(Int32,UAMonitoringParameters)

Contains new monitoring parameters (such as the sampling interval, and optional data change filter).

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).

Initializes a new copy of the EasyUASubscriptionChangeArguments object from the monitoring item handle, and monitoring parameters.
