i'm recently working on designing a Modbus RTU network over RS485,
i have 13 slaves, the distance between them is 40m, the totale distance is 650m, i will use a twisted paire cable with 22 AWG and 120Ω of characteristic impedance.
I want to know how to calculate the...
I have 130 devices connected in series with Rs485 by Modbus RTU protocol.
I know that RS485 has a limitation of 32 devices per segment.
And i can manage that by adding repeaters ..
My question is , if i make a convertion of modbus RTU to Modbus Tcp , the problem of limitation can be solved ...
