I don't think that you will get simulation under 4ms. This would mean to set the Unity Physics at values around 1ms and this will take a lot of computation load and won't work on bigger systems. Fastest Interface schould be via Simit, followed by PLCSimAcvanced but you would need to set Simit cycle times to low values. 

Hi Ahmo,these are likely Profibus/Profinet interfaces. There are three possible approaches you can take:

1️⃣ Write Directly to DB/EA Areas & Implement Custom Behavior Models

• This allows you to fully control the behavior but requires a lot of effort, especially for frequency converters, as you’d need to model their behavior in detail.

2️⃣ Bridge the Simulation on the PLC & Use Simplified Behavior Models in realvirtual.io

• Instead of fully implementing the detailed logic, you could introduce a “Simulation Mode” on the PLC and use simplified drive behavior models on realvirtual.io (e.g., basic current response models). This reduces complexity while maintaining a functional simulation.

3️⃣ Use Siemens' Behavior Models (Requires Simit & PLCSimAdvanced)

• Siemens provides dedicated behavior models for such cases, but this requires a Simit license and potentially PLCSimAdvanced or a Simulation Unit running alongside realvirtual.io. This is typically Siemens’ recommended approach.

Each option has its trade-offs in terms of complexity, cost, and realism.

Just for making sure that the setting is correct. Put/Get in PLC is enabled and the "virtual Network Interface" - don't know the exact name in PLCSimAdvanced is activated? Is any communication possible or is only DB Access not working?

I think we need to check on your computer. Do you have a time slot tomorrow morning?

ok thanks, will need to check the enabling in run mode. 

Ok, if something does not works for the prefabs with PIXYZ please let us know. Basically we are just exchanging the meshes and the rest should be unchanged if you update.

Hi Mark,

did you used CAD Updater (https://doc.realvirtual.io/basics/cad-import/cad-updater).

Usually we used this so far without prefabs (so when the mesh data has been in the model) after a standard CADLink import. Don't know how it behaves with Prefabs - this could be something we should examine a little bit more.

Ok will check this afternoon and send you here with a private message a new beta script.

Would you be able to test if I am sending you a beta implementation of the new interface code? This would be very kind because at the moment I don't have a S7 here available on my table.

Hi, this setup is not considered in the current implementation. We need to implement a non blocking reconnection method to the S7. We will implement it for the next release.
