Therefore, to allow communication over the RS485 bus, electronic components with TTL signal levels must use UART to RS485 signal converters, such as RS485 4 click. On the other hand, the converter circuit should offer enough ESD protection to prevent damage of sensitive TTL electronic components...
For connecting it with PC, the USB to RS-485 converter module is used. And the Arduino UNO with MAX-485 TTL to RS-485 converter module, the whole setup will look file follows: For using Modbus in Arduino UNO, a library <ModbusRtu.h> is used. This library is used for communic...
