Hi all! 

I am using the latest reavirtual. However, I am having problems with S7 TCPIP because the component displays "waiting to connect" and other error messages, and communication with S7-1200/1500 does not work, although it works with version 6.0.3. What could be the problem and what could be the solution? Thank you in advance for your hel

MQTT IN/OUTPUT ERROR [Repair] / realvirtual.io Forum / realvirtual.io (formerly game4automation)

Hi,

when we trigger our build pipeline and run tests or build the project via script, from time to time the HelloWindow pops up and blocks the pipeline run.

Context

• We are using realvirtual in a Unity project that we build and test via Azure DevOps.

• Unity is started from the pipeline in batchmode (no user interaction, headless build).

• Typical commands are like: -batchmode -projectPath <path> -runTests or -batchmode -projectPath <path> -buildWindows64Player <path> ...

Most of the time this works fine, but occasionally the HelloWindow appears during startup and seems to wait for user interaction. Since this happens on a build server without UI interaction, the process just hangs and the entire CI job times out.

Expected behavior

• When Unity is running in batchmode (CI environment), realvirtual should not open the HelloWindow at all, or

• There should be an option (e.g. a setting, scripting define symbol, or asset menu option) to completely disable the HelloWindow for automated builds/tests.

Actual behavior

• Infrequently, the HelloWindow still appears during CI runs, even though Unity is started in batchmode.

• This blocks the build/test pipeline until it times out.

Questions / requests

• Is there a recommended way to disable the HelloWindow for CI/batchmode runs?

• Could realvirtual internally check for Application.isBatchMode and skip showing the HelloWindow in that case?

• If there is already a setting or flag to turn this off, could you point me to the correct configuration?

Thanks a lot in advance!

Dear,

Thanks for your support.

I have another problem when realvirtual io package install in HDRP project.

1) Unity 6 LTS Version (6000.0.62f1)

2) Create HDRP Project

3) Install Reavirtual IO Digital Twin Professional (6.0.8)

→ Compile error occurs (see image below)

4) Switch to HDRP Menu (in realvirtual menu)
※ Render Pipelines > Switch to HD render Pipeline (HDR) > Path Tracing & Ray Tracing (Both Try)

→ Compile error still occurs (see image below)

I would like to request guidance on how to resolve this issue so I can use realvirtual io in HDRP project.

Best regards,

Seokhyun Lee

Dear,

Sorry But,

The problem is not solved.

I'm having trouble again with a compile error after installing RealVirtual AI Builder with Unity 6 LTS version.

1) Unity 6 LTS Version (6000.0.62f1)

2) Install RealVirtual IO Digital Twin Professional (6.0.8) & Simulation 6 (6.0.6) → OK

3) Install RealVirtual IO AI Builder 1.0
→ Compile error occurs (see image below)

I would like to request guidance on how to resolve this issue so I can use RealVirtual AI Builder.

Hi, 

When trying to make an S7 connection (new empty scene) in the realvirtual.IO starter kit I have following issue.
The connection is OK and running in Scene mode, but once in Game mode, I see I have following error:

Connection failed: get_gameObject can only be called from the main thread.
Constructors and field initializers will be executed from the loading thread when loading a scene.
Don't use this function in the constructor or field initializers, instead move initialization code to the Awake or Start function. 

In the connection view of TIA portal I see a lot of connection active.

Does anyone has any advise on how to solve this?

Hi everyone,

I’m trying to figure out the best way to model a gantry in realvirtual and I’d like to check if my approach makes sense.

Mechanical setup

• Think of a classic gantry crane

  

• In my machine I have
  

  • Two separate X-axes at the bottom (front and back rails – green arrows).
    They can move independently in X, but in normal operation they should behave like a gantry pair.

  • On top of them sits a Y-axis stage (blue arrows) that moves sideways.

  • 

• The Y-stage is physically connected to the X-axes via joints in Unity.

• The CAD / Unity hierarchy is basically flat – the Y-stage is not a child of one of the X carriages, so I cannot rely on parenting to move it together with X.

Control side

• I have separate drives / axis values for:

  • X-front

  • X-back

  • Y-stage

• The requirement is:

  • When X moves, the whole Y-stage must move with it.

  • Y should still have its own motion relative to the gantry.

Questions

1. What is the recommended realvirtual setup for this kind of gantry?

2. How should I combine this with joints?

   • Should I keep the joints at all, or would you recommend a purely kinematic Axis/Drive setup for this use case?

Any hints, best practices, or “don’t do this” stories are very welcome.
Thanks in advance!

I would like to simulate pick and place processes of parts by using kinematics without physics. I am struggling with my understanding of the MU, Source, Grip/Fix concepts.

What do I have to do to make a sourced MU part a subcomponent without physics?
