This library was created to make it easier to create communication between devices using ModBus RTU protocol, based on RS485 wiring. As it state in the title, library is written only for handling ...

Since Arduino's own MODBUS libraries do not support either the ESP32 or the RS485 Wing, I tested various other libraries and came across the ModbusRTUMaster and ModbusRTUSlave libraries by C. M.

Abstract: This paper explains how to set up the communication between PLC and Arduino based on Modbus Protocol. PLC is a master and Arduino is a slave. A Fx2N-48MR, a Fx2N-485BD, an Arduino main board ...
