Hello,

is there a easy way or can somebody provide suggestions how to move MUs in game mode with mouse navigation same as possible in scene view?

I purchased and installed the realvirtual.io plugin in Unity. Initially, everything worked fine, but after a few days, when I restarted Unity, all content related to realvirtual.io reported errors, and the toolbar options related to the plugin disappeared.

Hello Sir,

  Currently I have added the PLC Advance interface to my project. Also successfully to run the PLCSim advancedCoupler.exe. But after that, it shows that PLCSIMAdvance runtime not available. Can you please help on this

Hi, thomos, please update assistant when i try to fix some problems its not using recent knowdge.

thanks

Hello,

is there a way to combine two or more MUs ?

for example: MU1 (main part) is on a transport surface. At some point it stops and MU2 (smaller part) should be fixed onto MU1. They continue moving on transport surface together without falling apart. I tried to do this by attaching the fixer script to MU1 and unset the gravity of MU2. But with the fixer script MU1 is not moving anymore.

best regards

Carsten

Hi Thomas,

there seems to be a bug in Sensor (Script).

If I disable "Display Status" I see a purple graphical error only in game mode.

I tested this in "DemoGripping" version 2022.13.

Hi team please update S7 Connection Tutorial in youtube with new TIA19 and if possible update on PLCSIMAdvance v6 too

I've been using realvirtual.io for a week. But I'm struggling with kinematics links modeling.

As I see in your documentation, you are using either parenting or dynamics on game objects.

The thing is, for certain kinematics chains, neither technique worked...

There is futher example of mechanism i need to model :

There is a way to model complex kinematics chains (Without using mass and force)?

Yesterday, I tried to dive deeper into the kinematics of more "complex" objects in Unity. However, I reached my limits when working on the kinematics of the model in the attached image, and I wanted to ask for your assessment of the complexity involved.

From my experience, chaining linear and independent movements doesn't seem to be a problem. However, combining rotational and linear movements appears to be more complex.

The model is actually a relatively simple construction. On a base-plate, there is a rotatable and driven turret. At the top of this turret, there is a shaft driven by a motor, which, through a connecting rod-like mechanism, is supposed to exert a linear movement on the "sleeve" around the turret. I have illustrated this with two images.

I have tried various combinations of kinematic chains and also tested the use of Unity's internal joints like the "Hinge Joint." I always got to the point where I still needed to add the linear movement of the sleeve. However, I couldn't implement this final step under the conditions of the existing movements.

In general, I have the following questions:

• Is it possible to use the joints provided by Unity in combination with the drives from Realvirtual?
• Are there any similar "joints" from Realvirtual that constrain kinematic movement (i.e., without additional drive)?
• I had the feeling that a functioning kinematics heavily depends on the hierarchical arrangement of the game objects. It seems that the linear constraint of the sleeve to the turret doesn't work due to the hierarchy. Do you have any tips or rules that need to be followed, and is such a kinematic chain as desired in the model even possible?

I have also attached the STEP file of this model and would appreciate any feedback.

I want to interface the realvirtual digital twin with a c# application. The c# application already exists and controls resources like motors with resource commands. The commands are already expressed in a message that is send via TCP. No PLC is used.

An example message would be:

- message type -> eg resource command request

- object id -> eg Xaxis

- command id -> eg move

- parameters -> eg position, speed, acceleration and deceleration parameters

The individual parameters in the message are extracted from the message by a decoding procedure.

I would like to use an industry standard like MQTT (or OPC UA) to interface with the digital twin. Therefore the TCP message has to be converted to a MQTT message.

I have limited knowledge in this area, but from what I understand is that the digital twin requires signals. Drive_DestinationMotor for example requires 5 PLC outputs and 4 PLC inputs, the PLC outputs/inputs should be mapped to signals, signals should be connected to MQTT topics, each MQTT topic represents 1 signal. Am I right?

I can understand how to convert the TCP message to multiple MQTT messages, but how can I make sure that parameters like position and speed signals are received all at once or before the actual "start drive" signal?

Are there examples available on how to do this or should I use a different approach? What would happen when I replace Drive_DestinationMotor by a controller with states? Are there examples of such a controller?
