OPC UA Driver

[nirtecBruker]

Hi,

I am testing communication between Siemens PLC and Machine Simulator over OPC UA. For this purpose I am just using the default machine #01 Easy Transfer Line

The connection and configuration is fine, and communication works flawless, so it is a really good feauture. I have used file -> save in order to bring up the config again for later.

However, if I close TIA Portal and/or Machine Simulator, or restart my PC, sometimes the loaded configuration loose the mapped variables, which is a bit annoying when you have to remap them. It is okay for this small machine, but it is not sustainable with larger amounts of variables.

Has this happened to anyone else? Is it me that is doing something wrong or is it a bug?
