Tutorial: Modbus TCP to MQTT - VB.net WinForm

 Hello innovators!

If you have Modbus data and you want to make it accessible from the internet, this video could be a perfect solution for you. 

The goal of this project is to publish Modbus TCP data to MQTT so we can access it from anywhere and any application.

This is a Modbus IOT (internet of things) project. 

Before you start, there are a few things you have to prepare:

1. get access to a MQTT broker. We will use Miqottt.com as a FREE MQTT broker. All you need to do is easily register, login and create a topic.

2. a Modbus device or simulator. We will use ModbusHD. You can get it from this link: https://youtu.be/gmmLis3Vk6Y

3. Visual Studio 2022 as an IDE for creating a project.

4. an application to check MQTT data. We will use MQTT Explorer. 

These are the steps:

00:00 - intro

00:10 - create a new VB WinForm project

04:26 - login to Miqottt.com to get MQTT topic

05:04 - configure Modbus Register address

08:32 - install package: EasyModbus, M2Mqtt

10:07 - Scripting

19:53 - test Modbus with ModbusHD

20:32 - scripting MQTT client

24:41 - test MQTT with MQTT Explorer

Thanks, and have a nice day!
