In this video I explain how to connect an Arduino Uno board to a Modbus Master device, using SimpleModbusSlave library. More info: github.com/multiopti/teaching
Hola Gustavo Gracias por compartir tu experiencia en este viso referente a como utilizar el arduino como Modbus slave. Deseaba saber como conectaste la parte material, Rx, Tx (1,0)? utilizaste una interface RS 485? Espero tu respuesta, creo que ibas a subir un video de esto.
Hi, nice video. I tried to use your sketch by installing SimpleModbusSlave library but I can't complile at all. I have an error about 'mbed.h' libraries. Can you suggest me how to solve problem? I have to connect a Arduino Uno to Schneider PLC by using Modbus RTU protocol. Thank you.
I am trying to monitor my 12v valence batteries that has 4 module in series at 3.65v each which is = 14.6v. Since these batteries have an internal bms, which has an amp connector. How can I monitor each module using arduino, rs485, logic level converter and 4 module relay?
You could use some circuit to measure the four required voltages, depending on the required accuracy you may have different solutions. Arduino UNO has 6 analog channels, so you could use it. RS485 is only required if you want to transmit the values to another device for other purpose. If you have Wifi connectivity, it is possible to connect your Arduino to a WiFi Shield and send data through Internet. I hope it helps you
@@gustavosanchez4522 It would be great.. have you any material (pdf, manual, instructions) to share with me? I have been working in my final thesis at my college...
Hola, Gustavo estoy investigando como comunicarme con el arduino en protocolo modbus, sin embargo, como tengo varios dispositivos como asigno el numero de terminal al dispositivo o mejor expresado donde le asigno la identificación al dispositivo
Saludos Excelente video, ¿Cómo puedo descargar ese software para simular un dispositivo MODBUS? tienes un enlace o podrias facilitarmelo a algún correo electrónico. Tengo un convertidor Modbus a USB que compré hace un año y no he logrado probar.
