I'm encountering difficulties accessing nodes within the OPCUA Server. While I can establish a connection with the server, the nodes aren't being properly imported into Unity.
Examining the image below, it's evident that input nodes contain nested nodes. However, as depicted in the screenshots, Unity fails to list all the available nodes.

I created an HMI object with 2 HMI tabs. The first tab stores a drop-down menu, and the second tab stores 3 HMI Panel World Space with HMI buttons. When I use Unity in Scene and Game mode , I can visualize the changes. However, after starting the simulation ( Play mode ), all the objects inside HMI wont appear on the game. All elements are on the UI layer.

as i descripte，i want to complete a machine digital twin which is similar with the example demo from your website shows.

Hello! I'm following the RealVirtual tutorials playlist and I'm on part 7, where Logic Steps scripts are added, but I can't find them in my version of the Asset. 

When I search, I only find the Control Logic Script.

I'm using the demo version, are these scripts only available in the Professional version?

I don't know how to use transport surface, I notice in the demo scene the conveyor belt works perfectly, but in my scene everytime I tried turn the whole conveyor 90 degree but the texture dose not follow and still goes as before. How do I fix this?Video

Hi, I bought 'realvirtual.io Digital Twin Professional 2021'.

whein I saw HMI components - realvirtual.io 

There are HMI Components  but, When I Downloaded on Asset Store There is no HMI Demo and Module.

how Can I Get this module?

When running the scene for extended periods of time we get the problem that the gripper script stops working. The sensor stop detecting MUs and it does not give any errors. Is there a problem in the background which comes up after running a scene for a long time?

Hi,

Now I have created two paths A and B using IK Path, when I repeat the signal quantity given to start for each path individually the paths can be executed correctly, but once I execute A and B alternately the paths are unreachable.

For example, I am using Signal Start to get path A to start moving, and Signal Ended to get if path A has finished executing. When Signal Ended is true for A, I start executing path B. It happens that path B can't finish execution and Signal Ended stays false.

This results in me not being able to control the robotic arm by itself to do the job I want to do, how can I solve this problem?

Good morning,

We are having problems with the OPC UA connection.

When the OPC server is turned off and on again the connection is reestablished correctly, but only once since startup, if the server disconnects a second time the connection is never reestablished.

How can we solve the problem?

Thank you.

Hello,

I recently purchased realvirtual for Unity and I am trying to get familiar with the demo application.

For future projects it is necessary to keep up OPC UA connections with Beckhoff TwinCat PLCs and Siemens PLCs.

For now I work with a Beckhoff PLCs that runs demo code and a OPC UA server on it.

Connecting to the OPC UA Server with OpcWatch or UaExpert is no issue (security = None)

My Unity configuration looks like this:

However trying to connect in the Unity Editor results in the following error message.

I tried applying standard setting and also connecting to a local python opc ua server without success.

Connecting to the PLC with the TwinCATInterface object however worked well (for future applications a wireless connection on android devices are mandatory).

Unity Version: 2022.3.14f1

realvirtual version: release 2022.07 07. September 2023

I hope I delivered sufficient information.

Thanks in advance.
