Remarks

The Sparkplug producer (edge node or device) is actively publishing data when its data source is connected, i.e. when OpcLabs.BaseLib.Communication.ConnectedCondition.ConnectionState of DataSourceCondition is OpcLabs.BaseLib.Communication.CommunicationConnectionState.Connected.

Changes in the data source condition are reported through the ISparkplugProducerEvents.DataSourceConditionChanged event.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
