This is a simple application (commercial / not free) for reading OPC DA and Modbus TCP that can be published as a Modbus TCP Server. We designed this app for Windows XP 32-bit, so the GUI is not pretty enough, but it can run in Windows 10.
You can purchase this little application (with full sourcecode) by sending me an email here:

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!
Hi innovators!
This tutorial shows you the easy way to create an application that displays Modbus data on a Chart object.
We use Visual Studio 2022, with C# and WPF .Net Framework type project.
These are the steps:
00:00 - Create a C# WPF Project
00:42 - Install EasyModbus & LiveCharts package
01:28 - Create Chart objects
08:28 - Coding / Scripting
14:37 - Test with Modbus TCP Server Simulator (ModbusHD)
18:30 - Change some parameters
The Modbus simulator (ModbusHD) can be downloaded from this link:

Thank you, and have a nice day!
This video tutorial shows you how to create a Mobus TCP Client app on mobile (Android) using Visual Studio with a Xamarin Forms C# project.
For Modbus TCP Server Simulator, please download ModbusHD application from here: https://drive.google.com/file/d/1qlb29iHVV4s2ykGiPQvSF1xa7I4dhFTe/view
Hi...!
I build some apps for iOS and Mac for Modbus:

This application is a Simulator for Modbus TCP Server.
Pada video kali ini kita akan membahas tentang project Modbus TCP Client untuk membaca dan menulis dalam tipe Float, baik Float biasa maupun Float SWAP.
Pada video kali ini kita akan belajar bagaimana caranya membaca banyak register Modbus TCP dengan bahasa VB.
Kita perlu memecah fungsi Read Register karena pada library EasyModbus yang kita pakai dibatasi sampai 125 register setiap sekali memanggil fungsi tersebut.
Silakan download file project nya disini:

Pada kesempatan kali ini kita akan membahas projek sederhana aplikasi Modbus TCP Multi Clients dengan bahasa VB.net
silakan download file sourcecode nya disini: https://drive.google.com/file/d/1pX6G-xcnUrIxY93oeH1HdmfKvNIWRfaF/view?usp=sharing aplikasi ModbusHD bisa didownload disini: https://hadiscada.blogspot.com/2020/09/modbushd-aplikasi-modbus-tcp.html
tambahan pada versi ini:
+ MenuModbusHD dibuat oleh HadiSCADA. Aplikasi ini bisa dijalankan sebagai Modbus TCP Server atau Modbus TCP Client, atau Modbus RTU Slave, dan atau Modbus RTU Master. Sedikit penjelasan: + pada Modbus TCP, istilah yang dipakai adalah Server-Client. Server sebagai penyimpan data/register dan Client yang membaca (polling). + pada Modbus RTU, istilah yang dipakai adalah Slave-Master. Slave sebagai penyimpan data/register dan Master yang membaca (polling). Cara pakainya silahkan lihat video berikut:
