Discovery of adding or deleting objects

Post by sandor.voros »

Dear all,

We would like to implement an OPC UA browser and it should recognize all changes that happens on the server side.
For the value changes it is quite straight forward, as one only has to subscribe to the value change event.
Is there a way to detect changes like adding, or deleting nodes, properties, folders, etc?
E.g. subscription to an entire namespace?

Many Thanks!

Cheers,
Sandor

Hi,

yes there is an event, the so called "ModelChangeEvent" that you can subscribe to. This event is fired whenever the Information Model changes. If so, your application can re-browse to find out what has changed.
