You can read inputs but if you use S7 TCPIP interface the inputs must be in a PLC memory area where no hardware is configured to. Otherwise the hardware input status will always overwrite what the S7TCP interface has written to the input.

It depends what you want to do. Because of Limitations in Unity PLCSim Advanced is a little bit more complicated (external coupling exe needs to be started). S7 Interface is easier and works on all Platforms. But with S7 interface you can't write to inputs where also a hardware is configured to.

You can't write on inputs which are configured in the hardware configuration like in a real PLC because the hardware status will overwrite / collide with your write.

You can't read Inputs per Definition. Inputs are Values going into the PLC. You can only read Outputs from the PLC.

Interact is a 3rd Party solution. Do you have got a license for interact?

Hi, I just checked your problem.

Currently I don't see an easy solution.

 You might check out the solutions of Traeger which gives you a more advanced access to OPCUA via C# (see https://docs.traeger.de/en/software/sdk/opc-ua/net/client.development.guide). 

If you want to switch to the solution of Trager we can refund you the money if you would like.

Ich werde mir die MoveCenter Funktion heute nochmals genauer ansehen - in der Praxis verwenden wir sie selbst praktisch nie. Am Besten einfach ein leeres Gameobject an die richtige Stelle setzen und den Rest dann darunter (alles ohne MoveCenter)

Hi, honestly I totally missed you upload. You should do it again.

But what you are doing is reading a not officially supported data type and structure. This is pure development and our for free support is only if you have bugs in standard feature and functions. But still - please send me the upload again (it might be already deleted) and I will have a look ino it.

You should have any kind of error in the console log which should point you in the right direction. 

Please always check and send us the log in case of problems.

Please try to set empty game objects to the correct rotation positions and don't use move center in this case.
