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 ...

This low-power transceiver module uses the Maxim MAX485 IC to enable serial communication over extremely long cable runs (up to 4000 feet / 1200 meters). At a data rate of up to 2.5Mbps, serial data ...

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 ...
