A simple GUI for reading data from OPC Server, ModBus, AB Contrologix 5000 or XML, directly from the terminal.
There is also a Worker Service that writes the required data (initialized by the GUI) to a local QuestDB.

For the OPC UA Servers you can insert Username:Password in the Path field.
Remember to trust the certificate or you will receive the error
Object reference not set an instance of object.<e>
For address of the tag, you need to insert the full path, for example
ns=2;s=Channel1.Device1.Tag1
For the moment like for the other components, it is used a direct Read and not a Subscribtion.
