Hi Labview user ,
I have a couple of question about OPC UA (i am a new user of OPC)
First question :
* I had to work with a siemens PLC and Labview using OPC UA to communicate between each other , the issue is that when i use the installable file i lose the OPC UA connection ,
is there a driver or somthing else missing that i should added to solve the problem?
*second question :
is there a dll file can we used for the OPC UA connection ?
thank you

Your build application should have an additional "data" folder and in there you should find at least ni_opcua.dll. But that is not enough, this is just the LabVIEW bindings for the LabVIEW OPC UA Toolkit support libraries. And if you want to install this built application on a different computer you also need an OPC UA Runtime Installation.

But this runtime also needs a paid license:
