Nice idea, but many functions need to be retested before going to production with all the CPU/s and Sinamics drives

@gijzelaerr do you need some help on your PR ?

maybe later on, for me it is a tryout to use AI coding tools for auto translation from C++ to python. Once i laid the foundation to have the old python wrapper communicate with the new low level code i can use some hand porting all the functions.

I think it's a great idea. Also, as a reference, there is a native implementation in Go: https://github.com/robinson/gos7

pyS7 has also been started.
