DLMS-COSEM through Serial Port

Hi Guruxs,

I'm trying to make sense of the DLMS User Association, my usual area is web development, but in this case, I need to implement a protocol of this type.

I am reading the blue book and also the green one, although it is difficult for me to think about how to create a frame to send through the serial port, I do not know if all the protocol requires an object-oriented model (blue book) or if only it is possible to know HOW TO CREATE a frame to send all the queries to the device, that is, like a script...

I want to give thanks above all for your time, I sorry.... if the question is not very clarifying.

Note: The language to be implemented would be the same, it would use Java / Python.

Thank you, happy code! :)
