How does the listener works? @Question

[JohnLeBuff]

Hello,
I have a question that I did not find in the documentation.
The OPCUA Listener Node, how does it work?

Does the listener request data from the server or is the listener a subscription to the “nodes”?

Because I use the injection node to inject many OPCUA variables that I want to retrieve and process in Nodered. Some of these variables are not updated if the state change is only for a short period of time e.g. 1.5 seconds.

Hope someone can help me and thanks
John

Subscription contains also sampling interval (100ms fastest) and publish is normally 1000ms.

This should work in your case.
