Exception	Description

Exception

Description

System.ArgumentOutOfRangeException

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.
