Hi,
i am wondering if i can subscribe to objects using opcua. I want to use OPC Toolbox together with a python-opcua/ asyncua server. But it seems like i can only poll the values.
Is it possible to implement Subscribtion in OPC Toolbox for opcua ?

Starting R2023b, you can now subscribe to data change events in OPC UA nodes using the "subscribe" function in the Industrial Communication Toolbox.
Here is an example of how to use this feature:
