OPC UA Node identifier #683

Closed johnbarbosas closed 3 months ago

johnbarbosas commented 5 months ago

Hello there, idk if it's an issue, but how can I access the OPC UA nodes using a string identifier, instead of using the number ID? Cause when edit my AAS on AAS Package Explorer and export this as a nodeset, the ID number changes every time, so even though I make a table including names and IDs, I need do remake this table every time I make a change on AAS.

I added this feature to read, which action needs this?

Code will detect that msg is not containing nodeId, it will translate browsePath back to nodeId and use it then... should be compatible with existing flows.

Thank you so much! I'll try it.

I've already updated the pallete, and tried a lot of things, but always get the same error:

"warning: properties like messageType, namespace, variableName or VariableValue is missing."

I use this command: br=/0:Objects/6:AASROOT/6:AssetAdministrationShell:myStation1/6:Submodel:Handling2/6:Feedback/6:Q_94_Claw_2_Cart/6:Value

Idk, but I think numbers refers to namespace and names refers to BrowserName/DisplayName (tried both, didn't worked).
