I need to find out what the exact functionality is of the slnet call in the automation script in the below screenshot.
I think the call updates the output label on the matrix.
I'm also interested in knowing where the related DCF interface label is being updated.
Would that be done by the same slnetcall by software?
Or is it the connector that will do the update?

Hi Jeroen,
What = 128 corresponds to UpdatePortsXml.
You can find all SLNet enum messages listed here: Enum NotifyType | DataMiner Docs
This SLNet call allows you to dynamically modify a matrix configuration.
For more details, see: Dynamically changing matrix configuration | DataMiner Docs
And for a complete description of this specific message, refer to: NT_UPDATE_PORTS_XML (128).
Regarding the last topic, I think the logic should probably be in the connector.
I hope this can help 😉
