The Modbus protocol was developed in 1979 by Modicon for industrial automation systems and programmable logic controllers with an Ethernet connection. It is used to transfer discrete/analog I/O ...

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 ...

The Arduino team has announced a new version of the Arduino PLC IDE, its integrated development environment for PLCs including the Arduino Opta range — now featuring full support for over-the-air ...

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 ...
