What is it good for? Allows you to connect your Modbus RTU slaves (such as sensors, energy meters, HVAC devices) to Modbus TCP/UDP masters (such as monitoring systems, home automation systems). You do ...

A library that allows your Arduino or MSP to communicate via Modbus protocol, acting as a slave. Supports serial (RS-232, RS-485), LoRa RN-2483 and IP via Ethernet (Modbus IP). - pawelpq/Modbus-Slave ...

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 ...
