Hello and thanks for the reply!
Yes I am interested in MODBUS protocol as it will make my project more compatible with existing RS-485 products out there. That way I could use some of the factory made modules for interconnection with our repeater controller if needed. I would appreciate if you could give me an working example of MODBUS protocol over RS-485 network. Thank you in advance.
