Arduino Slave Modbus RTU (RS232) - svtdhnlucom

While Modbus RTU specifications define the format of a data frame transferred over a serial line, the type of serial signal is not defined. Many Modbus sensors communicate over RS-485. To interface between RS485 and the TTL used by standard Arduino-type boards, you will need an RS485-to-TTL adapter.
