OPC UA: Contradiction between help documentation and example VI, some more infomation would be good.

Status: Declined

Filed as bug

The LabVIEW Help for the OPC UA Connect VI has this statement in the description of the "OPC UA data change event" output: "NI does not recommend using this output."

The example VI "Data Access Client.vi" inside "OPC UA Demo.lvlib" uses this output. Could it be possible to add a possible explanation as to why in the Example the "OPC UA data change event" output is used? Or could the Help for the OPC UA Connect VI be modified?

I have tried to find someone who knows the history of that example, but I have been unable to find anyone who knows definitively. I believe that the example was written early and the note about "NI does not recommend..." was added later, and the example was never updated. That toolkit is outside of LabVIEW

 

I will file a bug report to update the example to not use the terminal.
