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 ? Without adding repeaters !
The process is like that :
Rs485 ==> CONVERT TO Ethernet (tcp) ==> fibre optique ==> Convertion to Ethernet again ==> convertion to Rs485 again and connect to the SCADA .
