Using an Arduino to read a simple MODBUS/RTU RS-485

Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). Modbus has become a de facto standard communication protocol and is now a commonly available means of …

Modbus RTU Master With Arduino in 5 Minutes Part 1

I wrote a modbus supervisor (master) using visual basic some years ago which was tested against commercial modbus enabled controllers (aircon units in my case). I then wrote a progam for a pic microcontroller to talk modbus as a slave. the max485 chip at both ends of the comms link to convert the serial data message you build in your software.

/20/2018It was me who told you that some libraries for ModBus TCP on Arduino are not very reliable but that doesn't mean that the protocol has this deficit. Quote My socket should be installed far from the CDP , hence I prefer to not use a Modbus RS485 protocol, but it seems that it's the most reliable .

Modbus Communication protocol for Arduino as Slave

Modbus communication protocol over RS-485. Modbus is a serial communications protocol originally published by Schneider Electric in 1979 for use with its programmable logic controllers (PLCs). Modbus is located in the level 2 of the OSI model, and uses a master/slave (or client-server) architecture.

USE ARDUINO AS A MODBUS SLAVE OVER RTU

Modbus protocol For communication of the PROMOTIC application with the Arduino , the Modbus protocol seems to be the best choice. Both serial link( Modbus RTU ) and/or Ethernet ( Modbus TCP ) can be used as communication interface (based on the configuration of the microcontroller itself).
