is it possible to call method of OPCUA server?

I bought the OPCUA4UNITY asset recently, then I set up a simple opcua server with python-opcua (code is here). It’s able to connect the server, import the nodes, but there is no data showing in the inspector when I click the “Update Node” button.

I tried to debug in VS. It seems the "Value" property of opcNode is missing.

Then I used OPC watch, the value can be read.

I also tried other opcua servers, like UA-.NETStandard has the same problem and another problem is it cannot import all the nodes in unity.

For “OPC UA C++ Demo Server V1.7.0” server, value can be read correctly, but it cannot import all the nodes in unity.

I have struggled several days, please help me, thanks a lot!

Hello. I have since bought your OPCUA4Unity, and followed your tutorials in the YouTube video. I wish to refer to your Text with Delegate text. I tried doing the same thing but i am unable to output anything to my game. I am able to type in the "Text From OPCUA Node" and it comes out in the game. May I know how did you connect the script to the string that you wanted for display? 

In my case, I wish to reference it to the "Value". I have tested running your OPCUA_Node and Interface and they work well (sweet!) but as we know it does not show up in the game scene. So I hope you may advise me on what are the steps needed. Thank you!
