Exception in OPCUAConnection.Connect on Android

JGIngaa 2 years ago in OPCUA4Unity updated by Support 2 years ago 4

Hi all!

I am using the OPCUA4Unity asset in my project. When I run it on android devices an exception is thrown in game4automation.OPCUAConnection.Connect(). Here is the full output:

The type initializer for 'Opc.UaFx.Client.OpcClient' threw an exception. at game4automation.OPCUAConnection.Connect () [0x00000] in <00000000000000000000000000000000>:0
at game4automation.OPCUA_Interface.Connect () [0x00000] in <00000000000000000000000000000000>:0

UnityEngine.Logger:Log(LogType, Object)
game4automation.OPCUA_Interface:Connect()

I am able to run it in Unity Editor aswell as Win Standalone App. I am also able to connect with another OPC UA client from the same android device to the server.Is Android not supported?


Please let me know if you need additional infos!

Are you compiling with ILCPP and are you having .Net20 compatibility turned on. Are you allowing Internet Access for your Android Device?

I have a question for OPCUA trial version

jang 2 years ago in OPCUA4Unity updated by Support 2 years ago 4

안녕! OPCUA 시험 버전이 있습니까?

나는 경험하고 구매하기로 결정하고 싶다.

Answer

It is licensed on a purchase per set basis. Updates are included through the Unity Asset Store. We never tested it, but I am pretty shure that WebGL will not work. We are no planning extra effort to support WebGL.

help for reading values from opcua server

Yulong Ding 2 years ago in OPCUA4Unity updated by Support 2 years ago 5

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!

Display NodeID value as text in Unity

allenlimofficial 2 years ago in OPCUA4Unity updated by Support 2 years ago 3

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!

Hi,

a few questions from my side to understand the problem.

Did you checked the NodeID you want to display the text from with an OPC UA Browser (you can find several in the internet).

Is the text displaying if you use an OPCUA_Node Script - the text should be sown under value?

If both things can be answered yes the communication is correct and it is just a programming issue on your side.

What I am wondering about is, that your NodeID is called "Counter1". It seems more that it is not of type string. Maype you missed to convert the integer to a string?

Best regards

Thomas
