Syntax
'Declaration
 
Property PublishingInterval As Integer
'Usage
 
Dim instance As _UASubscriptionParameters
Dim value As Integer
 
instance.PublishingInterval = value
 
value = instance.PublishingInterval
int PublishingInterval {get; set;}
property int PublishingInterval {
   int get();
   void set (    int value);
}

Property Value

Valid values of this property are in the range from 0 to 2147483647 (Int32.MaxValue).

Unit of measurement is ms.

The default value of this property is 1000.

Returns the publishing interval (in milliseconds).
Exceptions
ExceptionDescription

The value of an argument is outside the allowable range of values as defined by the invoked method.

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

If you do not specify the publishing interval (leave it at zero), the component will calculate it by dividing the sampling interval (for the monitored item) by the automatic publishing factor (see OpcLabs.EasyOpc.UA.Engine.EasyUAClientEngineParameters.AutomaticPublishingFactor). The resulting value is limited by OpcLabs.EasyOpc.UA.Engine.EasyUAClientEngineParameters.FastestAutomaticPublishingInterval. This means that by default, the publishing interval equals to one half of the sampling interval.

In order to obtain or modify this parameter, access the OpcLabs.EasyOpc.UA.OperationModel.UAMonitoredItemArguments.SubscriptionParameters.
