Arduino Modbus Serial Trial Electronic Devices

Modbus SD Read & Write with Modbus Rtu communication.In Modbus RTU and Modbus ASCII, RS485 is used as the physical layer. Simple and robust, it has since become a de facto standard communication protocol, and it is now a commonly available means of connecting industrial electronic devices. Modbus is located in the level 2 of the OSI model, and uses a master/slave (or client-server) architecture. Modbus is a serial communications protocol originally published by Schneider Electric in 1979 for use with its programmable logic controllers (PLCs).

In this In this project I made, I used the SD and SPI libraries that came with Arduino and a library prepared by a developer called ModbusRtu.h. Simplex communication is unidirectional communication (one sends data and the other only receives data), with one arduino behaving only as transmitter and the other only as receivers. Simplex communication between two Arduinos by RS485. But in this project, we are only implementing simplex and half-duplex. Here Arduino Uno has two push.RS-485 can be implemented into three types of serial communication system: simplex, half-duplex, and full-duplex.

Here is the pro.YaptД±ДџД±m bu projede Arduino ile birlikte gelen SD ve SPI kГјtГјphanelerini ve ModbusRtu.h isimli bir geliЕџtiricinin hazД±rladД±ДџД± kГјtГјphaneyi kullandД±m. Eventually after finding no material online, I decided to look into it myself. I hope it will be a tutorial for those who are interested in such issues like me.I was trying to get modbus to work with ESP32 for a long time. While I was writing my Arduino code, I didn't pay much attention to the method, of course it can be developed further. Of course, I don't know how hard it is to get such information on another subject.
