Hello everyone.

I will work on MBUS master project in nowadays. I want to read 50 slave mbus calorimeters. Every meter has own battery.
So can you suggest me working master circuit about that?

Thanks!

Hi Devfirat,
here you have a little help, this is a working schematic I have used to connect  until 3 devices.
The resistor R110 is the main used to set the feedback voltage from the  slave devices to set reception.
For the unit you are planned  I think you need a little microcontroller and  some op. amp to set
a programmable voltage  in order to set the 0 state level.
