OPC UA browser example? How view the OPC UA servers structure, OPC UA client example?

[Ola_A]

While trying to learn the basics about OPC UA I like to have an OPC UA browser, to look at a OPC UA server.

I like to see/show the tree structure of folders, notes, attributes and the rest in an nice graphical way.

The OPC UA examples in Labview 2015 is a good starting point, from them I could probably build such a OPC UA browser. That would be a good and nice training for me, but since time is limited maybe someone already did it. I guess any commercial OPC Client also has the functionality of browsing a server? Does NI provide any OPC UA client for evaluation?

Hi,

        Yes NI provide DSC Module for evaluation, In this module u can browse OPC variables. There are also 3rd party softwares like Codesys, MatrikonOPC . Just try out, but building your own module would take some time because you need to understand the protocol.

Thanks jay0909!

I will see if I can get a recent DSC evaluation that includes OPC UA from NI.

But it would be fun to make a simple browser myself, I like to learn how to use the Tree indicator!

I also have the OPC UA toolkit and am disappointed that none of the standard NI OPC diagnostic tools and tag browsers seems to work with OPC UA.  I am missing something?

A while back I was messing around to see if I could create a simple OPC UA browser. As with many side projects I lost interest after getting some of the basic functionality working but I have some of the basic functionality up on GitHub if you wanted to take a look at that.

Right now you can point it at a server and it will build out a basic tree structure for you which will display the browse name but have the actual tag value tied to the unique node id.

Have been taking a look at your example and can use it to see all of the tags on my cRIO OPC UA server, very nice!

This is a good beginning to something that really should come with the OPC UA toolkit.  I would like to see if I can extend your example to function like the Distributed System Manager which is a great tool for browsing NSV's.
