Main changes:

The code has been refactored in order to facilitate the configuration from config.json.
Server and client scripts that use asyncua library instead of opcua library have been added.
Main.py script has been replaced by one of the client scripts: client-opcua.py or client-asyncua.py.
Now the OPC-UA server can be created running one of the server scripts: server-opcua.py, server-opcua-xml.py, server-asyncua-.py or server-asyncya-xml.py.
Currently tested on Windows, Ubuntu 22.04 and Python>=3.8

@alq-eium , I've solved the issue with glibc 2.31. Instead of installing a newer glibc, I've installed openmodelica in the workspace and exported the compatible FMU. After doing that, the log seems fine. Please check below:

▶ python client-asyncua.py

In addition to the pip commands in the README, I had to do:

apt-get install build-essential libssl-dev libffi-dev python3-dev
pip install pyopenssl --upgrade

for the example to work.

alq-eium commented 9 months ago

Thank you @prasadtalasila , I will update the README. Regarding the additional commands, I think that it will happen again if we change the Operating System or the Python version since in a VM with Ubuntu 22.04.3 it works with pyOpenSSL version 23.3.0. Maybe the the best way to ensure that all needed Python libraries are installed, is to export a requirements.txt and import it, instead of typing the libraries by hand:

Exporting:
```
pip freeze > requirements.txt
```
Importing:
```
pip install requirements.txt
```

I will do it in a clean Python environment for the Linux version of DTaaS

prasadtalasila commented 9 months ago

Thanks.

alq-eium commented 9 months ago

Hi Prasad these are the updates:

script.mos that compiles the Modelica model into an FMU. After installing Open Modelica Compiler just run omc script.mos and the FMU will be compiled.
requirements_linux.txt and requirements_windows.txt that contain the list of pip packages and its versions. Now running pip install requirements_linux.txt should be enough to install all Python dependencies

prasadtalasila commented 9 months ago

@alq-eium Thanks for the updates. I will check these tomorrow and merge it.
