Hello friends.
Its been a while. I once posted a problem, where i wanded to read from one adress, that contained multiple information. For example adress 100 was listed in the documenation and contained multiple values:
ADR: 100.1 (bool value X)
ADR: 100.2 (bool value Y)
ADR: 100.3 (bool value Z) (and so on)
If someone want to read it: First project. Is Node-red the way to go
Here is my solution, how to read from an adress 100 that is splited into 6 "sub" adresses (100.1 , 100,2 ...)

My problem rn is, now kinda the same, but now i want to write to an adress that has "subadresses". For example, i want to write to the adress 101.1, I tried to find an answer and tested around to make it work, but i cant find a way to manage it. I am a bit confused ho to implement the buffer parser in the writing process. Thats what i have so far:
