I implemented your chain script as descript in https://game4automation.com/documentation/current/chain.html and as you have done in the scene DemoChain. The rotation of my chain elements are not correct and jumps at some points along the chain. All my anchers and all their tangent have rotation (0,0,0). I don't understand what I have done wrong. 

Hi,

 I use CADLink importing a model into scene and want to make a MU.  How to change it to a prefab quickly ? Thanks so much.

Here is code od RobotDK script.

Here is solution for S7PLC connect to PLCSIM Compact, comment in S7Interface disconection timeout.

SetPDU to 10 (working not stable and max 5 byte in, 5 byte out)

And using Nettoplcsim-S7o-v-1-2-4-0 program

Some features in configs NetToPlcsim

start.cmd

//

sc stop "S7DOS Help Service"
START /B NetToPLCSim.exe -f=S7Test.ini -s=NO -autostart

TIMEOUT /T 4
sc start "S7DOS Help Service"
TIMEOUT /T 4
"D:\Program Files\Siemens\Automation\S7-PLCSIM V15_1\Bin\Siemens.Simatic.PlcSim.Compact.exe"

S7Test.ini

//

[Station_1]
Name=PLC#001
NetworkIpAddress=192.168.88.50 //External IP of PLCSIM , adress of Ethernet board
PlcsimIpAddress=192.168.0.1   //internal IP of PLCSIM , not change this one
PlcsimRackNumber=0
PlcsimSlotNumber=0
TsapCheckEnabled=False

And now can connect to PLCSIM

Hi,

I am wondering whether G4A includes some way to automatically derive a meaningful object hierarchy and derive relations (e.g. spatial relations such as RCC8 relations). When you import models from CAD, there is often quite a "flat" hierarchy, i.e. most objects will be on the same level (e.g. a screw is on the same level as a motor). But this is usually not what you want, it would be better to have a "higher-level" hierarchy computed based on the positions of objects relative to each other. Similar with the relations like adjacent etc. Is there a way to derive this automatically in G4A? In the documentation I could not find anything.

Best regards,

Christiane

Hi I am using DEMOOPCUA on unity 2020.1.13f1. I am working directly on the demo templates. After switching to a different opc ua server, information are not automatically updated, this is unlike in the original demo template where data are automatically updated. Is it something that i am missing?   

Helo. Im trying to connect s7-1200 with game4automation. I saw the tutorial video and the https://game4automation.com/documentation/current/s7tcpip.html.

I followed all the process but still not working with this signs keep cycling.

I successfully checked the connection and added sdf file as well.

S7 interface plc input write error CPU : Function not available

I don't know how to solve this problem. Thank you.

I've started a project with the game4automation asset. I have a robot connected with the roboDK interface. When I try to open the project with another PC, It appears this error:

ArgumentNullException: Value cannot be null.

It seems like some paths from the old PC are still remembered by the asset. I have changed the RoboDK Application path and the RoboDK file path, but the error stays. Reinstalling the asset just works, but it is uncomfortable to do it every time I switch to another PC.
