Hello everyone,

I try to write a data server, that subscribes to data from an OPC UA Server and push this data to another client.

In the SubscriptionNotificationListener the function onDataChange(…) is called for every MonitoredDataItem individually, but my aim is to call one function for all MonitoredDataItems that changed in the PublishingInterval, like the onNotificationData(…) function. I tried this function, but I only get the values and can’t match the values to the MonitoredItems they refer. Is there a function or a way to get a list of changed MonitoredDataItems after each PublishingInterval? I didn’t find a way until now.

I hope my problem is understandable.

Kind regards,
jakblu

Try this:

				if (notificationData instanceof DataChangeNotification) {
					DataChangeNotification dataChangeNotification = (DataChangeNotification) notificationData;
					for (MonitoredItemNotification notification : dataChangeNotification
							.getMonitoredItems()) {
						MonitoredDataItem item;
						try {
							item = (MonitoredDataItem) Subscription.getItem(notification
									.getClientHandle());
	...
