I am still not sure if I understand your question, but I will try. If I misunderstood, let me know.

In QuickOPC, you are making method calls to subscribe the individual monitored items. The OPC UA subscriptions are maintained for you automatically by the component.

All monitored items that use the same parameters share the same subscriptions. So, if, for example, you subscribe to all your items with sampling rate 1000 milliseconds, and also do not set other subscription parameters, there will be *one* subscription created for all of them by QuickOPC.

If you then subscribe to one or more monitored items with sampling rate 2000 milliseconds, they will go into a second subscription, and so on.

Best regards

Hello,

So I mean if you want to monitoring one nodeid on the OPC server, you must subscribe it to the server for monitoring. In the DeviceExplore.Config.xml you can define "maxsubscriptioncount" on the server. Question how can check how many subscription is created/active?

Thank you.
