I was wondering when will OPC UA for Unity 2019 will be supported?
With kind regards,
Stan (Developer at Siemens)
Hi, we have no tutorial about that.Even if Unity 2019 is not officially supported yet, you should be able to get it running. What is your problem. What kind of error messages do you have?
is it possible to run the OPCUA Interface inside a webgl app? I tried with Unity 2018.4.15 and 2019.2.17 and always got a "Memory index out of range" error in Chrome and Edge.
No WebGL is not supported - sorry. I also think that communicating in a Web application over OPCUA might also be not wished from the security point of view.
since the last update I get an LicenseException when building for Android. I only get the error on the device not in the editor.
"LicenseException: The supplied license is not longer supported for this version. You need to renew your support subscription to use this version of the OPC UA Framework Advanced."
I use the OPCUA4Unity asset from the asset store. Since I get this error on already shipped devices I realy need a quick solution. Thank you!
I am closing this. We can't reproduce it.
I can connect to my OPC UA server from OpcWatch, UA Expert and even Node-RED.
However wenn importing nodes I get an error message that the client would not be able to connect. I've attached a log-file. Does someone has any idea?
Which version are u using. I can't reproduce. With 1.026 Update works. Used Demo Model and UaCPPServer to check.
Do you have a small demo model - based on UaCPPServer where I can check your issue?
Can you write to OPC UA variable using the PLCInputFloat varible type. I easily read values from the PLCOutputFloat inside scripts using the "variableName".Value method but I cannot seem to write using the datatypes.
I am able to change to variables on OPC UA server using other applications.
I am sending you via email a link to the current beta asset!
I get an error from UnityLinker (see below) in Unity 2019.2.2f1, Android and PC Standalone build. The project also uses LWRP which, I assume, is not so important here. I did not test with standard rendering. I can reproduce this error in an empty project just importing the OPCUA4Unity asset. Other settings are IL2CPP, Net Standard 2.0.
Edit: Maybe it is helpfull to know, that Mono Scripting Backend does not run into this.

sorry we don't have a solution for the problem. Because of Unity is changing very fast we decided to relay on the Long Term Support releases which give long term support and better stability. So my advice is to use Unity 2018.4.8f1 and other 2018.4 Versions
I am using OPCUA4Unity in my Hololens Unity project. An exception is thrown when I try to connect to an OPCUA server from the Hololens. Here is the 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"
I am able to connect just fine in Unity Editor, but not when connecting in Hololens.
I have ensured that the build settings are correct (IL2CPP, .NET 2.0 compatibility), and have set the permissions to allow internet access in Hololens. I am on Unity 2018.4.8f1, and have tried upgrading my project to 2019.1.14f1 but that did not fix the issue.
Let me know if you need more information!
the problem must be inside the included DLL. We agreed with our supplier of the DLL to wait to receive our Hololens2 to be able to test and to find the issue. For now we can only say that Hololens is not working (it was not only you who is not able to get it working).
No currently I think not. I would propose to use OPC UA. Is there a public API for FactoryTalk Communication. If yes it could be easily integrated with some programming.
Dear game4automation team,
so far the OPCUA4Unity asset works very smooth. Great work!
In my project I tried to update my data like you show in the DemoTextWithDelegate example. But the subscription object returned in OPCUA_Interface :
sub = connection.SubscribeNodeDataChange(nodeid,del);
is pretty much empty:
I used UAExpert to test the subscription with the same node id, which worked. As far as I can tell I do not get any warnings or errors. Here is my code how I subscribe:
private OPCUANodeSubscription _safetyLevelSubscription; //subscription is a class member [...] _safetyLevelSubscription = _interface.Subscribe(node.NodeId, SafetyLevelNodeChanged); //this is the call [...] public void SafetyLevelNodeChanged(OPCUANodeSubscription sub, object obj) //this is the delegate signature
Now, I noticed that the OPCUAInterface gameobject holds pretty much all the nodes of the top node as childs and keeps them up to date. At least in the editor. Wouldn't it be best practice then to always access those child OPCUA_Nodes instead of adding an additional subscription?
Thanks for your thoughts!
Maybe I should add, that the delegate is not called when the value on the OPC UA server changes. I assume it is due to the null ptr in the subscription. Also, I use a codesys opc ua stack.
Thanks for the positive feedback. Please give us a review in the Asset Store if you like it.
You have both options. Subscribe in code or use the imported child nodes for accessing the values.
Usually the subscription gets null if the server is not reachable. Some servers are also limiting the number of subscriptions - maybe this is the case on your server. Do you see anything in the console log?
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!
Hi, we tested it also with android and it shoudl workl.
Are you compiling with ILCPP and are you having .Net20 compatibility turned on. Are you allowing Internet Access for your Android Device?
