Modbus RTU Slave Implementation on Arduino - Read Sensory Data and Save it to RTU Slave Registers

This Video demonstrates how to Implement a Modbus RTU Slave on an Arduino. The Tutorial shows how to read sensory data using the Arduino and then writing this data to slave registers. The Modbus RTU Master can then access this data by reading the slave registers.
The implementation is done using an Arduino Nano and a ModbusRTUSlave Library

One of the clearest video to explain arduino as modbus slave. Good job 🎉

Hy, I'm looking to implement these function in Arduino to communicate with Artisan Scope to control a FAN, heater and temperature with MAX6675K. Can you do a video on how to read a write these register please? Thank you and congratulations for the content!

[@pedroadolfogalani858]

Thanks for the video. Please, which modbus simulator did you use? where can I find?

[@InstrumentacionExterran]

Si porfavor como se llama el simulador que usas en este video

[@mohammedrezk8072]

Very informative Video , my question is there a way to make Arduino master device ? , Thanks for your efforts.

[@brightersidehacks]

Yes, a video on that is coming soon as well

[@caiocezar7199]

Very good video
In this case, you use the Arduino programming serial port to carry out this communication with the modbus simulator.
What would it look like using a MAX485 type converter?

[@mihecmuhec2876]

Very clear and simple code, exactly what I was looking for. But I would like to connect the output to the MAX485 module. Then I could feed the data into the Modbus loop.
How to do it?

Here is a video using Max232 : ruclips.net/video/bHuYg5lF_-8/видео.html
